Unlike general HVAC brands that added a data centre line, precision cooling is the whole business. That focus shows up in the things that actually matter on a critical site: high sensible heat ratio so the unit removes heat instead of wasting capacity on dehumidification, EC fan technology, close control of temperature and humidity, and a controller designed to run several units as a coordinated group rather than as competing thermostats.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 16px 0;\"\u003eIndigi Power and Cooling supplies, installs, commissions and maintains STULZ precision cooling equipment throughout Australia. We are a critical power and cooling contractor, not a general air conditioning firm, so the same team that sizes and installs your CRAC units also handles the UPS, the switchboard work and the ongoing maintenance regime. That matters because cooling failures in a server room are usually not cooling failures at all. They are power problems, control problems or airflow problems that a cooling-only contractor is not equipped to diagnose.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 28px 0;\"\u003eThis page sets out the STULZ range by capacity band, explains the difference between DX and chilled water CyberAir configurations, covers the CRAC versus CRAH question that trips up most buyers, and explains what Indigi can do for STULZ equipment you already own, including units that somebody else installed.

It comes in two fundamentally different forms, and the choice between them is a building decision rather than a cooling decision.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:20px;font-weight:700;color:#111111;margin:26px 0 10px 0;\"\u003eCyberAir 3PRO DX, 20 to 150 kW\u003c\/h3\u003e\n\n\u003cp style=\"margin:0 0 16px 0;\"\u003eThe DX version carries its own refrigeration circuit and rejects heat to an external condenser, dry cooler or condensing water loop. It is the right answer where there is no central chilled water plant, or where the IT room needs to be thermally independent of a base building system that shuts down out of hours. STULZ builds it in six sizes across five cooling systems: A and AS for air-cooled operation, G for glycol, GE and GES with integrated indirect Free Cooling, ACW for a combined air and chilled water arrangement, and GCW for glycol with chilled water backup. That last group matters more than it sounds, because dual-source units let a site keep cooling when either the refrigeration circuit or the water plant is unavailable.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 16px 0;\"\u003eAirflow configurations are ASD downflow into a raised floor, ASU upflow for rooms without a floor void, and ASR for raised floor return. Refrigerant options across the family have included R407C, R410A, R134a and the lower global warming potential options R513A and R454C. Refrigerant choice is not a detail in Australia. Any work on the circuit requires a licence under the Ozone Protection and Synthetic Greenhouse Gas Management Regulations, and the refrigerant charge influences both the levy exposure and the availability of gas for future top-ups.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:20px;font-weight:700;color:#111111;margin:26px 0 10px 0;\"\u003eCyberAir 3PRO CW, 22 to 260 kW\u003c\/h3\u003e\n\n\u003cp style=\"margin:0 0 16px 0;\"\u003eThe chilled water version has no compressor. It is a coil, an EC fan array and a control valve, fed from a central chiller plant. Eleven sizes are available, in CW single circuit and CW2 dual circuit forms, the latter allowing two independent water sources for concurrent maintainability. ASR and ABR variants are built for hyperscale halls where very large air volumes have to be moved with minimal fan energy. If your building already has a chiller plant with spare capacity, CW is almost always the cheaper and more efficient choice per kilowatt, and it scales much further than DX before the electrical infrastructure becomes the constraint.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 28px 0;\"\u003eIf you are still weighing the topology decision, our \u003ca href=\"\/pages\/crac-unit-faq-what-is-the-difference-between-dx-chw-and-cdw-crac-systems\" style=\"color:#d9590c;\"\u003eDX, CHW and CDW comparison\u003c\/a\u003e works through the trade-offs in detail, and our \u003ca href=\"\/pages\/server-room-cooling-australia\" style=\"color:#d9590c;\"\u003eserver room cooling\u003c\/a\u003e page covers room design, containment and redundancy.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:26px;font-weight:800;color:#111111;margin:36px 0 16px 0;\"\u003eCyberRow and high-density racks\u003c\/h2\u003e\n\n\u003cp style=\"margin:0 0 16px 0;\"\u003ePerimeter cooling runs out of headroom somewhere between 8 kW and 15 kW per rack, depending on how disciplined the containment is. Above that, the air simply cannot be delivered to the front of the cabinet fast enough or cold enough, and you get hot spots regardless of how much total capacity is installed in the room. CyberRow addresses this by sitting in the row, drawing hot air horizontally from the hot aisle and discharging cold air directly into the cold aisle over a short path.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 16px 0;\"\u003eEach CyberRow delivers 11 kW to 58 kW and can cool up to six cabinets, in three widths so it can be fitted into an existing row layout. Because the air path is horizontal, no raised floor is required, which makes it viable in office-building server rooms and retrofit situations where a floor void was never built. In practice, in-row cooling takes a room from the 5 kW to 8 kW per rack that legacy perimeter units support up to the 30 kW to 40 kW range without structural work. Beyond that, you are into liquid cooling, and our \u003ca href=\"\/collections\/liquid-cooling-solutions\" style=\"color:#d9590c;\"\u003eliquid cooling range\u003c\/a\u003e and \u003ca href=\"\/pages\/data-centres-it-infrastructure\" style=\"color:#d9590c;\"\u003edata centre infrastructure\u003c\/a\u003e pages cover the options.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 28px 0;\"\u003eOne point worth stating plainly, because it is routinely missed: in a high-density room, the thermal ride-through after a cooling failure can be under a minute. If the cooling plant is not on protected power, the room will hit over-temperature shutdown long before the UPS batteries protecting the IT load are exhausted. Cooling on UPS is not optional in a high-density design. We cover the electrical side of that on our \u003ca href=\"\/pages\/three-phase-ups-installation-commissioning-australia\" style=\"color:#d9590c;\"\u003ethree phase UPS installation\u003c\/a\u003e page.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:26px;font-weight:800;color:#111111;margin:36px 0 16px 0;\"\u003eSmall server rooms, switchrooms and outdoor shelters\u003c\/h2\u003e\n\n\u003cp style=\"margin:0 0 16px 0;\"\u003eMost Australian critical cooling is not hyperscale. It is a 12 kW comms room in a regional council building, a battery room behind a switchboard, or an equipment shelter on a hill somewhere with no one on site. STULZ builds specifically for that end of the market, and it is the segment where most generic HVAC installations go wrong.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:20px;font-weight:700;color:#111111;margin:26px 0 10px 0;\"\u003eCyberAir Mini, 5.9 to 34.7 kW\u003c\/h3\u003e\n\n\u003cp style=\"margin:0 0 16px 0;\"\u003eCyberAir Mini is the successor to MiniSpace and covers 5.9 kW to 34.7 kW across four sizes. It is built for small server rooms, equipment rooms, UPS rooms and battery rooms. The distinction from a domestic split system is the sensible heat ratio. A comfort cooling unit is designed to remove humidity from a room full of people. A precision unit is designed to remove dry heat from a room full of electronics, so nearly all of its rated capacity does useful work, and it holds setpoint continuously rather than cycling. Battery rooms in particular need stable temperature, because valve-regulated lead acid life halves for roughly every 8 to 10 degrees Celsius of sustained elevation above 20 degrees.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 16px 0;\"\u003eIf you have MiniSpace units in service, they are now legacy equipment. That does not mean they need replacing today, but it does mean spare parts lead times get longer each year and a replacement plan is worth having.

Free Cooling is standard across much of this range, which is the whole point for unattended sites: when the outside air is cool enough, the compressor stays off and the unit runs on fans alone at a fraction of the energy. For a remote site running on a limited power budget, or one where a generator refuel trip is a day's driving, that difference is operationally significant rather than merely economic.

STULZ offers it as Direct Free Cooling on CyberAir units and as an integrated indirect option in the GE and GES cooling systems. The economics depend entirely on how many hours a year the ambient sits below your changeover point, and in Australia that varies enormously by location.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 16px 0;\"\u003eMelbourne, Canberra, Hobart and the Adelaide Hills get genuinely useful Free Cooling hours through autumn, winter and spring. Sydney gets a moderate benefit. Brisbane gets less. Darwin, Cairns and the Pilbara get very close to none, and any vendor promising large Free Cooling savings on a tropical site should be asked to show the bin hours. The related lever in warm climates is raising the server inlet setpoint. ASHRAE TC 9.9 recommends an inlet range of 18 to 27 degrees Celsius, and most Australian rooms are still run at the bottom of that band out of habit. Moving the setpoint up within the recommended envelope, with proper containment so hot and cold air do not mix, usually delivers a larger and more reliable saving than Free Cooling does north of the Tropic of Capricorn.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 28px 0;\"\u003eDirect Free Cooling brings outside air into the room, so filtration and hygiene become live issues. AS\/NZS 3666 governs air handling system hygiene, and coastal salt, bushfire smoke and construction dust are all real considerations for Australian sites. ISO 16890 rated filtration and a maintenance regime that actually changes filters on schedule are part of the design, not an afterthought.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:26px;font-weight:800;color:#111111;margin:36px 0 16px 0;\"\u003eCRAC or CRAH: what the difference actually is\u003c\/h2\u003e\n\n\u003cp style=\"margin:0 0 16px 0;\"\u003eThis is the question buyers get wrong most often, partly because the industry uses the terms loosely and partly because STULZ builds both under the same CyberAir name. A CRAC unit, computer room air conditioner, contains a refrigeration circuit. It has a compressor, an evaporator coil and an expansion device, and it rejects heat to an outdoor condenser or a water loop. A CRAH unit, computer room air handler, has no compressor at all. It is a chilled water coil with fans and a modulating valve, and the actual refrigeration happens in a central chiller somewhere else in the building.\u003c\/p\u003e\n\n\u003cdiv style=\"overflow-x:auto;border-radius:8px;border:1px solid #2a2a2a;margin-bottom:28px;\"\u003e\n  \u003ctable style=\"width:100%;border-collapse:collapse;font-size:16px;line-height:1.4;\"\u003e\n    \u003ccaption style=\"caption-side:top;text-align:left;font-size:14px;color:#777777;padding:0 0 8px 2px;\"\u003e\n      Table: CRAC versus CRAH compared, mapped to the STULZ CyberAir range\n    \u003c\/caption\u003e\n    \u003cthead\u003e\n      \u003ctr style=\"background-color:#111111;color:#ffffff;\"\u003e\n        \u003cth scope=\"col\" style=\"padding:13px 16px;text-align:left;font-weight:700;border-right:1px solid #333;\"\u003eConsideration\u003c\/th\u003e\n        \u003cth scope=\"col\" style=\"padding:13px 16px;text-align:left;font-weight:700;border-right:1px solid #333;\"\u003eCRAC (direct expansion)\u003c\/th\u003e\n        \u003cth scope=\"col\" style=\"padding:13px 16px;text-align:left;font-weight:700;\"\u003eCRAH (chilled water)\u003c\/th\u003e\n      \u003c\/tr\u003e\n    \u003c\/thead\u003e\n    \u003ctbody\u003e\n      \u003ctr style=\"background-color:#fafafa;\"\u003e\n        \u003cth scope=\"row\" style=\"padding:11px 16px;font-weight:700;border-right:1px solid #e3e3e3;border-bottom:1px solid #e3e3e3;\"\u003eSTULZ product\u003c\/th\u003e\n        \u003ctd style=\"padding:11px 16px;border-right:1px solid #e3e3e3;border-bottom:1px solid #e3e3e3;\"\u003eCyberAir 3PRO DX, CyberAir Mini, CyberRow DX\u003c\/td\u003e\n        \u003ctd style=\"padding:11px 16px;border-bottom:1px solid #e3e3e3;\"\u003eCyberAir 3PRO CW and CW2, CyberRow CW\u003c\/td\u003e\n      \u003c\/tr\u003e\n      \u003ctr style=\"background-color:#ececec;\"\u003e\n        \u003cth scope=\"row\" style=\"padding:11px 16px;font-weight:700;border-right:1px solid #e3e3e3;border-bottom:1px solid #e3e3e3;\"\u003eRefrigeration located\u003c\/th\u003e\n        \u003ctd style=\"padding:11px 16px;border-right:1px solid #e3e3e3;border-bottom:1px solid #e3e3e3;\"\u003eInside the unit, in the IT room\u003c\/td\u003e\n        \u003ctd style=\"padding:11px 16px;border-bottom:1px solid #e3e3e3;\"\u003eIn a central chiller plant, outside the IT room\u003c\/td\u003e\n      \u003c\/tr\u003e\n      \u003ctr style=\"background-color:#fafafa;\"\u003e\n        \u003cth scope=\"row\" style=\"padding:11px 16px;font-weight:700;border-right:1px solid #e3e3e3;border-bottom:1px solid #e3e3e3;\"\u003eBest suited to\u003c\/th\u003e\n        \u003ctd style=\"padding:11px 16px;border-right:1px solid #e3e3e3;border-bottom:1px solid #e3e3e3;\"\u003eRooms up to roughly 150 kW, sites with no chiller plant, tenancies needing thermal independence\u003c\/td\u003e\n        \u003ctd style=\"padding:11px 16px;border-bottom:1px solid #e3e3e3;\"\u003eLarge halls, campuses and any building with spare chiller capacity.

As a guide to project scale, server room cooling design and installation runs from $8,000 to $15,000 for a small room, $25,000 to $45,000 for a medium installation, and $45,000 to $60,000 and above for large deployments.

In data centre use it usually means a CyberAir computer room air conditioner or a CyberRow in-row unit. The difference from ordinary air conditioning is that a STULZ unit is designed to hold a tight temperature and humidity band continuously, with a high sensible heat ratio so almost all its capacity removes dry heat from electronics rather than moisture from the air.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:20px;font-weight:700;color:#111111;margin:26px 0 10px 0;\"\u003eWhat are CRAC units?\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 16px 0;\"\u003eCRAC stands for computer room air conditioner. A CRAC unit is a self-contained precision cooling system with its own refrigeration circuit that maintains a data centre or server room within a defined temperature and humidity envelope, typically 18 to 27 degrees Celsius at the server inlet under ASHRAE TC 9.9. It differs from a CRAH unit, which has no compressor and instead uses chilled water supplied from a central plant. STULZ builds both, as CyberAir DX and CyberAir CW respectively.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:20px;font-weight:700;color:#111111;margin:26px 0 10px 0;\"\u003eHow much do CRAC units cost?\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 16px 0;\"\u003eEquipment cost depends on capacity, cooling system, refrigerant and configuration, so precision cooling is quoted per project rather than sold from a price list. As a guide to installed project cost in Australia, Indigi prices server room cooling design and installation at $8,000 to $15,000 for a small room, $25,000 to $45,000 for a medium installation and $45,000 to $60,000 or more for large deployments. The unit itself is usually well under half the delivered cost once electrical supply, condenser or pipework runs, controls and commissioning are included.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:20px;font-weight:700;color:#111111;margin:26px 0 10px 0;\"\u003eWhat are the main STULZ product lines?\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 16px 0;\"\u003eThe main lines are CyberAir, the perimeter CRAC and CRAH family available in DX from 20 to 150 kW and chilled water from 22 to 260 kW; CyberRow, in-row cooling from 11 to 58 kW for high-density racks; CyberAir Mini, 5.9 to 34.7 kW for small server, equipment and battery rooms and the successor to MiniSpace; CyberLab for laboratories and archives needing plus or minus 0.5 K control; and a shelter and cabinet range from 1 to 16 kW covering SplitAir, WallAir, TelAir, ShelterAir FC and CabinetAir PRT.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:20px;font-weight:700;color:#111111;margin:26px 0 10px 0;\"\u003eWhere is STULZ headquartered?\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 16px 0;\"\u003eSTULZ is headquartered in Hamburg, Germany. The company was founded in 1947, remains family owned, and manufactures precision air conditioning and humidification equipment sold worldwide.

Service level controller passwords are deliberately restricted and we do not publish them, because the parameters behind that level change compressor protection, fan curves and alarm thresholds and an incorrect entry can damage the machine. Send Indigi the model and serial number and we will help you get the right documentation or attend site to make the change safely.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:20px;font-weight:700;color:#111111;margin:26px 0 10px 0;\"\u003eHow does STULZ compare with Vertiv CRAC units?\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 16px 0;\"\u003eBoth are credible precision cooling manufacturers and either will work in a well-designed room.

In data centre use it usually means a CyberAir computer room air conditioner or a CyberRow in-row unit. The difference from ordinary air conditioning is that a STULZ unit is designed to hold a tight temperature and humidity band continuously, with a high sensible heat ratio so almost all its capacity removes dry heat from electronics rather than moisture from the air.\"}},\n{\"@type\":\"Question\",\"name\":\"What are CRAC units?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"CRAC stands for computer room air conditioner. A CRAC unit is a self-contained precision cooling system with its own refrigeration circuit that maintains a data centre or server room within a defined temperature and humidity envelope, typically 18 to 27 degrees Celsius at the server inlet under ASHRAE TC 9.9. It differs from a CRAH unit, which has no compressor and instead uses chilled water supplied from a central plant. STULZ builds both, as CyberAir DX and CyberAir CW respectively.\"}},\n{\"@type\":\"Question\",\"name\":\"How much do CRAC units cost?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Equipment cost depends on capacity, cooling system, refrigerant and configuration, so precision cooling is quoted per project rather than sold from a price list. As a guide to installed project cost in Australia, Indigi prices server room cooling design and installation at $8,000 to $15,000 for a small room, $25,000 to $45,000 for a medium installation and $45,000 to $60,000 or more for large deployments.

The company was founded in 1947, remains family owned, and manufactures precision air conditioning and humidification equipment sold worldwide. Australian buyers deal with local supply and service partners rather than the factory directly, which is why local parts availability, technician coverage and response times matter more to total cost of ownership than the badge on the unit.\"}},\n{\"@type\":\"Question\",\"name\":\"Where do I find a STULZ CRAC unit manual or the controller password?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Manuals are model specific and published by STULZ, so start with the model and serial number on the unit's data plate. Service level controller passwords are deliberately restricted and we do not publish them, because the parameters behind that level change compressor protection, fan curves and alarm thresholds and an incorrect entry can damage the machine. Send Indigi the model and serial number and we will help you get the right documentation or attend site to make the change safely.\"}},\n{\"@type\":\"Question\",\"name\":\"How does STULZ compare with Vertiv CRAC units?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Both are credible precision cooling manufacturers and either will work in a well-designed room. STULZ is a specialist that builds only precision cooling and humidification, with a particularly strong small and mid capacity range and a deep shelter and outdoor cabinet offering. Vertiv, formerly Emerson Network Power, has the larger Australian installed base under the Liebert name and a broader portfolio spanning UPS, busway and monitoring. On most Australian projects the deciding factors are local parts availability, technician coverage and how the unit integrates with existing plant rather than any headline specification difference.\"}}\n]}\n\u003c\/script\u003e\n","products":[{"product_id":"stulz-cyberair-3pro-dx-precision-air-conditioning-australia","title":"STULZ CyberAir 3PRO DX Precision Air Conditioning Units Australia","description":"\u003cdiv style=\"box-sizing:border-box;max-width:960px;margin:0 auto;padding:28px 20px;font-family:Arial,Helvetica,sans-serif;font-size:17px;line-height:1.6;color:#222222;\"\u003e\n\u003cp style=\"font-size:15px;color:#888888;text-transform:uppercase;letter-spacing:0.5px;margin:0 0 10px 0;\"\u003eHome \/ Precision Cooling \/ STULZ \/ CyberAir 3PRO DX\u003c\/p\u003e\n\u003cdiv style=\"background-color:#fafafa;border-left:4px solid #d9590c;border-radius:6px;padding:16px 20px;margin-bottom:28px;\"\u003e\n  \u003cp style=\"margin:0;font-size:19px;\"\u003e\n    \u003cstrong\u003eThe STULZ CyberAir 3PRO DX is a direct expansion (DX) computer room air conditioning unit delivering 20 kW to 150 kW of cooling capacity in six sizes and five cooling systems, engineered for data centre and server room applications across Australia.\u003c\/strong\u003e\n    It is available in downflow (ASD), upflow (ASU) and raised floor (ASR) air conduction, with Direct Free Cooling and Indirect Dynamic Free Cooling options that cut compressor running costs substantially.

A CRAC unit runs continuously, every hour of every day, and is sized on sensible heat rather than the latent load that dominates an office system. The CyberAir 3PRO DX sits at the upper end of that category. It is the direct expansion member of the CyberAir 3PRO family, built on more than three decades of STULZ development work, and it is specified where a site needs high cooling density from a small floor plate without giving up efficiency.\u003c\/p\u003e\n\u003cp\u003eFor Australian operators the appeal is usually threefold. The unit fits through a standard doorway despite its capacity, which matters when retrofitting an existing comms room in a CBD tower. It holds supply air temperatures inside the ASHRAE TC 9.9 recommended envelope, which keeps the IT load reliable and the energy bill defensible. And its Free Cooling variants exploit the cooler shoulder seasons in Melbourne, Canberra, Hobart and inland New South Wales, where outside air can carry a meaningful share of the annual cooling hours.\u003c\/p\u003e\n\u003cp\u003eIndigi Power and Cooling is an Indigenous and Veteran owned critical power and cooling specialist, registered with Supply Nation and ICN Gateway.

The FreeCool Plenum sits on top of the unit with dampers, so it consumes no extra floor area. Operation moves through three stages automatically. In Free Cooling mode the outside air damper opens and the compressor stays off entirely, with return air mixed in if the outside air is too cold. In mixed mode the compressor runs at partial load to top up capacity. In compressor mode the outside air damper closes and the unit cools conventionally. STULZ rates the fully economised case at up to 90 per cent more economical than compressor only cooling.\u003c\/p\u003e\n\u003cp\u003eThe catch is that outside air enters the white space, so this suits sites with wider temperature and humidity tolerances. In coastal Australian locations, salt laden air and bushfire smoke events are real considerations that should be weighed at design stage.\u003c\/p\u003e\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 10px 0;\"\u003eIndirect Dynamic Free Cooling\u003c\/h3\u003e\n\u003cp\u003eNo outside air enters the building. Heat is rejected through a water or glycol circuit to an external dry cooler, with an integrated Free Cooling coil in the unit. STULZ describes this as the only system with automatic efficiency optimisation, because there is no fixed changeover setpoint. Variable speed pumps, variable speed dry cooler fans and EC compressors are all regulated together against outside temperature and current heat load, which STULZ states reduces total energy consumption by up to 60 per cent across all active components.\u003c\/p\u003e\n\u003cp\u003eAn Extended Free Cooling mode holds cooling capacity constant by increasing airflow instead of starting the compressor, which lengthens the number of hours per year that run compressor free.

Electrical work must be carried out by a licensed electrician to AS\/NZS 3000, and any work on the refrigerant circuit requires an ARCtick licensed refrigeration technician under the Ozone Protection and Synthetic Greenhouse Gas Management Regulations. Where the unit serves a mechanical ventilation system, AS\/NZS 3666 hygiene obligations also apply. Indigi handles all of this in house rather than subcontracting the critical path.\u003c\/p\u003e\n\u003cp\u003eTypical scope covers heat load verification against the actual IT draw rather than the nameplate, condenser or dry cooler siting and pipe run design, rigging and placement, refrigerant charging and leak testing, controller configuration and BMS integration over Modbus, sequencing setup where multiple units share a room, and witness commissioning with documented handover. Indicative pricing for server room cooling design and installation runs from $8,000 to $15,000 for small rooms, $25,000 to $45,000 for medium installations and $45,000 to $60,000 plus for large projects. Quoted scope always depends on the site.\u003c\/p\u003e\n\u003cp\u003eOnce running, the unit needs a maintenance regime that reflects continuous duty. Filters are the most common cause of a gradual capacity loss and the filter control manager will flag them, but the schedule should also cover coil condition, condensate management, refrigerant charge, compressor and fan health, humidifier service where fitted, and controller alarm history review.

ASU is upflow, discharging from the top of the unit for rooms without a floor void. ASR is the raised floor version, where the fan box is relocated into the floor void.

Indigi Power and Cooling supplies, installs, commissions and maintains CyberRow in row cooling units nationally from hubs in Brisbane, Sydney and Melbourne.\n  \u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003eRack densities have moved. A data hall designed a decade ago sized 3 kW to 5 kW per cabinet and pushed cold air out of a floor void to the room at large. A hall carrying GPU compute, virtualisation clusters or dense blade chassis now routinely sees 15 kW, 25 kW or more in a single cabinet, and a room level cooling strategy simply cannot deliver enough air to the front of those racks fast enough. The result is a hot spot: one or two cabinets running well above the rest of the hall while the perimeter CRAC units work hard and over supply everything else.\u003c\/p\u003e\n\u003cp\u003eIn row cooling solves that by shortening the air path. The CyberRow is a narrow cabinet, 300 mm, 400 mm or 600 mm wide and 1,950 mm high, that is bolted into the row alongside the racks it serves. Air travels metres rather than tens of metres, and because the unit is measuring temperature at the racks themselves rather than at a return grille on the wall, it responds to what the servers are actually experiencing. STULZ describes the CyberRow as professional server rack cooling with innovative air conduction, and the design intent shows in the details: horizontal air distribution, up to five independent fans, and six temperature sensors across the front and rear faces.\u003c\/p\u003e\n\u003cp\u003eIndigi Power and Cooling is an Indigenous and Veteran owned critical power and cooling specialist, registered with Supply Nation and ICN Gateway.

The CyberRow supports both of the standard containment strategies, and the correct choice drives which air conduction option you order.\u003c\/p\u003e\n\u003cdiv style=\"display:grid;grid-template-columns:repeat(auto-fit,minmax(280px,1fr));gap:18px;margin-bottom:24px;\"\u003e\n  \u003cdiv style=\"border:1px solid #e3e3e3;border-radius:8px;padding:16px;background-color:#fafafa;text-align:center;\"\u003e\n    \u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:0 0 6px 0;\"\u003eCold aisle containment\u003c\/h3\u003e\n    \u003cp style=\"font-size:15px;color:#555;margin:0;text-align:left;\"\u003eUnits with a frontal air outlet blow straight down the enclosed cold aisle.

Cold air is thrown along the front of the rack line and hot air is collected close to where it is produced, so the mixing that normally occurs in an open hall is substantially reduced without erecting doors and roof panels. That matters in Australian comms rooms and small data halls where the room is shared, the ceiling is low, or the building owner will not permit structural aisle work.\u003c\/p\u003e\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eThree zone control and Delta T regulation\u003c\/h2\u003e\n\u003cp\u003eA tall cabinet does not have one temperature. The top of a 42U rack running dense compute is frequently several degrees warmer than the bottom, and a cooling unit that reads a single average will either starve the top or over cool the whole rack to protect it. The CyberRow addresses this with three temperature sensors on the front, three on the back, and up to five independently variable EC fans.\u003c\/p\u003e\n\u003cp\u003eThe controller measures Delta T between supply and return across each of three horizontal zones and adapts cooling capacity in each zone individually. In practice one fan bank may sit at 42 per cent while the two above it run at 65 and 67 per cent, because that is what the racks in front of them are asking for. Hot spots are removed without the energy penalty of an across the board over supply, and because EC fan power varies roughly with the cube of speed, small reductions in fan duty produce disproportionately large savings on a 24 hour a day load.\u003c\/p\u003e\n\u003cp\u003eThe controller also carries two mutually independent setpoints, typically a fixed supply air setpoint and a fixed Delta T setpoint between supply and return air. Holding both at once is what allows precise temperature control at the server inlet while still managing the volume of air moved, rather than trading one against the other. STULZ develops the controller in house, which is why the Free Cooling operating modes, the zone logic and the fan redundancy behaviour are handled as one integrated control strategy rather than bolted together from third party parts.\u003c\/p\u003e\n\u003cp\u003eFan redundancy is worth calling out separately. If a fan fails, the remaining fans automatically speed up to hold capacity, so a single fan fault does not become a thermal event while a technician is dispatched. The controller monitors and reports all faults, and a standard RS-485 serial port allows integration into a building management system over Modbus or STULZ protocols. Optional humidity sensor, electric heater and humidifier are available where the room needs active humidity control as well as sensible cooling.\u003c\/p\u003e\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eChoosing between the cooling systems\u003c\/h2\u003e\n\u003cdiv style=\"overflow-x:auto;border-radius:8px;border:1px solid #2a2a2a;margin-bottom:28px;\"\u003e\n  \u003ctable style=\"width:100%;border-collapse:collapse;font-size:15px;line-height:1.4;\"\u003e\n    \u003ccaption style=\"caption-side:top;text-align:left;font-size:14px;color:#777777;padding:0 0 8px 2px;\"\u003eTable: CyberRow cooling system options and where each one fits an Australian site\u003c\/caption\u003e\n    \u003cthead\u003e\n      \u003ctr style=\"background-color:#111111;color:#ffffff;\"\u003e\n        \u003cth scope=\"col\" style=\"padding:13px 16px;text-align:left;font-weight:700;border-right:1px solid #333;\"\u003eSystem\u003c\/th\u003e\n        \u003cth scope=\"col\" style=\"padding:13px 16px;text-align:left;font-weight:700;border-right:1px solid #333;\"\u003eDescription\u003c\/th\u003e\n        \u003cth scope=\"col\" style=\"padding:13px 16px;text-align:left;font-weight:700;\"\u003eTypical fit\u003c\/th\u003e\n      \u003c\/tr\u003e\n    \u003c\/thead\u003e\n    \u003ctbody\u003e\n      \u003ctr style=\"background-color:#fafafa;\"\u003e\n\u003cth scope=\"row\" style=\"padding:11px 16px;font-weight:700;border-right:1px solid #e3e3e3;border-bottom:1px solid #e3e3e3;\"\u003eA \/ AS\u003c\/th\u003e\n\u003ctd style=\"padding:11px 16px;border-right:1px solid #e3e3e3;border-bottom:1px solid #e3e3e3;\"\u003eAir cooled direct expansion with an external air cooled condenser.

There is no direct cable or refrigerant connection between the rack and the cooling unit, so the unit can be positioned wherever the thermal model wants it without being tied to a particular cabinet. Water connection openings are pre cut as standard at both the top and the bottom of the cabinet, which means the same unit suits an overhead reticulation design or an under floor one without site fabrication. The housing is powder coated with doors front and rear, and the electrical box pivots out for service, so a technician working in a live aisle is not forced to break containment or shut down a neighbouring rack to reach a component.\u003c\/p\u003e\n\u003cp\u003eThe zigzag G4 filter sits in a metal frame and is changed from the aisle. On a continuously running unit the filter is the most common cause of a gradual, unnoticed capacity loss, so filter change intervals should be set against the actual dust load of the room rather than a generic annual schedule.

Electrical work must be carried out by a licensed electrician to AS\/NZS 3000, and any work on the refrigerant circuit of an A, AS, GS or GES unit requires an ARCtick licensed refrigeration technician under the Ozone Protection and Synthetic Greenhouse Gas Management Regulations. Where the installation forms part of a mechanical ventilation system, AS\/NZS 3666 hygiene obligations apply to the air handling components and to the cleaning and inspection regime.

We measure server inlet temperatures at commissioning and confirm they sit within the ASHRAE TC 9.9 recommended envelope of 18 to 27 degrees Celsius, because that is the number an auditor or a hardware vendor will ask about, not the unit's supply air temperature.\u003c\/p\u003e\n\u003cp\u003eIndicative pricing for server room cooling design and installation runs from $8,000 to $15,000 for small rooms, $25,000 to $45,000 for medium installations and $45,000 to $60,000 plus for large projects. A typical in row retrofit of two to four CyberRow units into an existing row, including pipework and controls integration, usually lands in the medium band. Quoted scope always depends on the site, the pipe run and how much work has to happen out of hours.\u003c\/p\u003e\n\u003cp\u003eOnce running, the unit needs a maintenance regime that reflects continuous duty. The schedule should cover filter condition and replacement, coil cleanliness, condensate management, refrigerant charge and leak checks on DX models, chilled water valve and actuator operation on CW and CW2 models, fan bearing and EC fan health across all five fans, controller alarm history, and verification that the zone sensors are still reading correctly after any rack moves.

The actual number depends on the load per cabinet, the containment arrangement and the air conduction option selected.

Indigi Power and Cooling supplies, installs, commissions and maintains CyberAir 3PRO CW units nationally from hubs in Brisbane, Sydney and Melbourne.\n  \u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003eOnce a facility grows past a handful of racks, cooling stops being a room-by-room problem and becomes a plant problem. At that point it is usually cheaper and more reliable to make cold water centrally with high efficiency chillers and distribute it, rather than put a compressor inside every unit on the floor. The CyberAir 3PRO CW is the air handling half of that arrangement. STULZ describes it as an innovative chilled water air conditioner for data centers, and in practice it is the workhorse CRAH unit that sits at the end of a data hall row, takes chilled water in, and turns it into a controlled volume of cold supply air.\u003c\/p\u003e\n\u003cp\u003eThere is no compressor, no refrigerant charge and no condenser to find roof space for. What the unit does contain is a large chilled water coil, EC fans, filtration, and the STULZ controller that keeps supply air inside the ASHRAE TC 9.9 recommended envelope. Because the compression work happens back at the chiller, the unit itself draws very little power, and the engineering argument shifts from compressor efficiency to two other things: how little fan energy it takes to move the air, and how warm the water can be while still meeting the load. Both of those are where this range is designed to win.\u003c\/p\u003e\n\u003cp\u003eIndigi Power and Cooling is an Indigenous and Veteran owned critical power and cooling specialist, registered with Supply Nation and ICN Gateway.

Chilled water is generated centrally, distributed in flow and return mains, and delivered to CyberAir 3PRO CW units on the data hall floor. On the left the units discharge into a raised floor plenum and cold air rises through perforated tiles into the cold aisle. On the right a slab floor room is served without a floor void. The same unit family covers both, which matters when a campus has mixed legacy and new build space and the operator wants one spares holding and one control platform across all of it.\u003c\/p\u003e\n\u003cp\u003eTwo consequences follow from that architecture and they are the reason large sites choose chilled water. First, all the noisy, maintenance-heavy rotating plant sits outside the white space, so work on a chiller does not mean work inside a secure data hall. Second, capacity is added by adding air handling units on an existing pipe main rather than by re-engineering refrigerant runs, which is how a staged build is meant to work.\u003c\/p\u003e\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eAir conduction options\u003c\/h2\u003e\n\u003cdiv style=\"display:grid;grid-template-columns:repeat(auto-fit,minmax(240px,1fr));gap:18px;margin-bottom:24px;\"\u003e\n  \u003cdiv style=\"border:1px solid #e3e3e3;border-radius:8px;padding:16px;background-color:#fafafa;text-align:center;\"\u003e\n    \u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:0 0 6px 0;\"\u003eUpflow and Downflow\u003c\/h3\u003e\n    \u003cp style=\"font-size:15px;color:#555;margin:0;text-align:left;\"\u003eFans inside the cabinet.

Cabinet height rises to 2,915 mm on sizes 4, 5, 7 and 8 to carry a larger heat exchanger and more airflow per unit.

Fan power is a genuinely continuous load: it runs at full duty every hour of the year, including the hours when the IT load is light. Moving the fans into the floor void, shortening the air path and removing internal pressure losses drops Airflow Efficiency Ratio to around 0.11 to 0.14 W per cubic metre per hour across the published ASR range, against 0.14 to 0.17 for the equivalent high cabinet models.

Almost all of the electrical input sits in the chiller and the pumps. That reframes what a good CRAH unit does: its job is to make the plant behind it cheaper to run, and the way it does that is by working properly at warmer water temperatures.\u003c\/p\u003e\n\u003cp\u003eThe published CyberAir 3PRO CW tables are quoted at 12 degrees Celsius flow and 18 degrees Celsius return. Historically many Australian data halls were designed around 6 or 7 degree flow temperatures, inherited from comfort cooling practice, which forced the chiller to work hard year round and made Free Cooling almost impossible outside winter. STULZ designs the CyberAir 3PRO CW around higher air and water temperatures, and states that this increases the number of Free Cooling hours available at the chiller. That is the mechanism that actually moves annual energy consumption, and it is why raising the design water temperature is usually the first thing worth examining on an existing site.\u003c\/p\u003e\n\u003cp\u003eThe second lever is flow rate. STULZ states that the unit achieves its duty at a reduced water flow rate, which lowers system power consumption because the pumps do less work, and lowers investment cost because smaller hydraulic components can be specified. On a large hall, pipe diameter, valve sizing and pump selection are a meaningful share of the mechanical capital budget, so this is not a rounding error.\u003c\/p\u003e\n\u003cp\u003eThe third is air temperature optimisation in line with the ASHRAE recommendation. ASHRAE TC 9.9 puts the recommended server inlet envelope at 18 to 27 degrees Celsius. Running the cold aisle near the top of that band rather than the bottom raises the return air temperature to the coil, which raises the temperature difference across the coil, which in turn allows the warmer water and the reduced flow rate described above. All three levers are the same lever seen from different ends, and they only work together if the containment is honest and hot and cold air are genuinely separated.\u003c\/p\u003e\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 10px 0;\"\u003eReading the published EER figures correctly\u003c\/h3\u003e\n\u003cp\u003eThe EER values in the tables above, from 33.1 to 53.8, look extraordinary next to the 4 to 5 range quoted for a DX unit. They are not comparable, and it is worth being explicit about why. On a chilled water unit the EER expresses cooling capacity against the electrical input of the unit itself, which is essentially the fans, because the compression work happens back at the chiller and is not counted here. A whole-of-system efficiency comparison has to include the chiller, the pumps and the heat rejection plant. Treat the unit EER as a measure of how efficiently this box moves and conditions air, and use plant modelling, not this number, for a PUE case.\u003c\/p\u003e\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 10px 0;\"\u003eCW2 and what redundancy actually buys\u003c\/h3\u003e\n\u003cp\u003eThe CW2 cooling system connects a single unit to two independent chilled water circuits. If one circuit is isolated for maintenance, fails, or loses its pump set, the unit continues to cool from the other. Compare that with the conventional approach of installing N+1 whole units: CW2 puts the redundancy inside the cabinet, which saves floor space and means the redundant capacity is not sitting idle in a separate machine. The trade is duty per cabinet. As the table shows, a size 8 ASR 2160 CW2 delivers 195 kW against 273 kW for the single circuit ASR 2410 CW at the same physical size, because the coil face is shared between two circuits. Whether that trade is worth making depends on how your chilled water distribution is arranged and what your resilience obligations look like, which for regulated Australian operators often means an APRA CPS 230 style operational risk assessment rather than a purely engineering judgement.\u003c\/p\u003e\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 10px 0;\"\u003eContainment, filtration and air hygiene\u003c\/h3\u003e\n\u003cp\u003eA CRAH unit only performs to its published numbers if the air it receives is the air the selection assumed. Cold aisle or hot aisle containment, blanking panels in every unused rack U, and sealed floor cutouts are what keep bypass air and recirculation from eroding the temperature difference across the coil. Filtration to ISO 16890 protects the coil face from fouling, and a fouled coil is one of the most common causes of a slow, unexplained capacity loss on chilled water plant.

There is no refrigerant pipe run to design and no external condenser to site, but there is hydraulic work: flow and return connections, isolation and regulating valves, strainers, air venting, insulation, and a control valve that has to be sized for authority rather than convenience. Get the valve authority wrong and the unit hunts, which shows up later as unstable supply air temperature and unnecessary fan modulation.\u003c\/p\u003e\n\u003cp\u003eElectrical work must be carried out by a licensed electrician to AS\/NZS 3000. Where the unit is specified with a DX backup circuit, or where the wider system includes chiller work, any intervention on a refrigerant circuit requires an ARCtick licensed refrigeration technician under the Ozone Protection and Synthetic Greenhouse Gas Management Regulations. Where the installation forms part of a mechanical ventilation system, AS\/NZS 3666 applies to hygiene, cleaning and record keeping. Indigi holds these capabilities in house rather than subcontracting the critical path.\u003c\/p\u003e\n\u003cp\u003eTypical scope covers heat load verification against actual IT draw rather than nameplate, hydraulic connection and commissioning of the water circuit, balancing and flow verification, rigging and placement including the floor void fan box on ASR and ABR units, controller configuration, BMS integration, sequencing where multiple units share a hall, and witness commissioning with documented handover. Indicative pricing for server room cooling design and installation runs from $8,000 to $15,000 for small rooms, $25,000 to $45,000 for medium installations and $45,000 to $60,000 plus for large projects. Large chilled water hall projects sit at the upper end and above, and scope always depends on the site.\u003c\/p\u003e\n\u003cp\u003eOnce running, a chilled water unit needs a maintenance regime built around water, air and controls rather than refrigerant. That means coil condition and cleanliness, filter differential pressure and changeout, condensate tray and drain integrity, valve and actuator operation, water quality and glycol concentration where used, fan bearing and EC motor health, and a review of controller alarm history.

Indigi Power and Cooling supplies, installs, commissions and maintains CyberAir Mini units nationally from hubs in Brisbane, Sydney and Melbourne.\n  \u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cp\u003eMost Australian IT rooms are not data halls. They are a 10 to 40 square metre room in an office floor, a hospital wing, a council depot or a school, carrying anywhere from four to twenty racks plus a UPS and its batteries. That room still needs the same things a data hall needs: stable supply air temperature, tight humidity control, continuous 24\/7 duty and filtration that keeps dust off the electronics. What it does not have is floor space, a plant room, or a budget that stretches to a 100 kW machine.\u003c\/p\u003e\n\n\u003cp\u003eThe CyberAir Mini exists for exactly that gap. It covers 5.9 kW to 34.7 kW across four cabinet sizes and six cooling systems, with airflow from 1,800 to 9,200 cubic metres per hour. STULZ builds it to deliver the maximum cooling capacity from a minimal footprint, using the largest heat exchanger and filter surface areas that will fit inside the cabinet, EC fan technology and intelligent control to hold running costs down. It is a computer room air conditioning unit in the proper sense, sized on sensible heat and running every hour of the year, not a comfort split system asked to do a job it was never designed for.\u003c\/p\u003e\n\n\u003cp\u003eIndigi Power and Cooling is an Indigenous and Veteran owned critical power and cooling specialist, registered with Supply Nation and ICN Gateway. We supply, install, commission and maintain CyberAir Mini units across Australia, and we also service the large installed base of older STULZ MiniSpace equipment already running in Australian comms rooms.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eMiniSpace becomes CyberAir Mini\u003c\/h2\u003e\n\n\u003cp\u003eIf you have a STULZ unit in your comms room that was specified any time from the late 1990s through to the early 2020s, there is a good chance it is a MiniSpace. STULZ has renamed and re-engineered that range as the CyberAir Mini, bringing it into line with the CyberAir naming used across the rest of the precision cooling portfolio. The product does the same job in the same part of the market. It is the small-capacity, floor-standing, front-access precision unit for rooms that are too small for a data hall CRAC and too critical for a comfort system.\u003c\/p\u003e\n\n\u003cp\u003eThe commercial point matters more than the naming. Australian sites searching for STULZ MiniSpace parts, service or a like-for-like replacement are now looking at a product with a different name, and that creates a genuine risk of a facilities manager concluding the range has been discontinued and defaulting to a comfort split. It has not been discontinued. It has been superseded, and the successor is a better unit.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 10px 0;\"\u003eThe upgrade path from an existing MiniSpace\u003c\/h3\u003e\n\n\u003cp\u003eA MiniSpace to CyberAir Mini replacement is usually one of the simpler precision cooling projects on a site, because the fundamentals carry across. Cabinet height remains 1,980 mm, which is the dimension that most often governs whether a unit will physically go into an existing room with a suspended ceiling. Widths of 540 mm, 740 mm, 940 mm and 1,140 mm sit in the same family of footprints. Front access servicing means the replacement can go back against the same wall in the same position. Where the existing unit is chilled water fed, the pipework route, the condensate drain and the electrical supply are frequently reusable with minor modification.\u003c\/p\u003e\n\n\u003cp\u003eWhat changes is the efficiency and the control. Current EC fan technology, larger heat exchanger surface area and the modern STULZ controller with its optional touchscreen typically produce a material reduction in fan energy and a much better part-load response than a unit designed two decades ago. Refrigerant is the other driver. Older units commonly ran R407C or R22 in the oldest cases, whereas current DX CyberAir Mini units use R513A at GWP 631 and the hybrid Free Cooling variants use R454C at GWP 148.\u003c\/p\u003e\n\n\u003cp\u003eThe practical sequence we run is a site survey and heat load verification, a selection against the actual measured IT load rather than the nameplate of the outgoing unit, a staged changeover plan that keeps the room cooled while the swap happens, and full commissioning with documented handover. On a single-unit room that usually means temporary cooling for the changeover window.

An EER of 22.25 on the CCD 90 CW means the unit is moving roughly 22 kW of heat for every kilowatt of electrical input at the stated conditions, because there is no compressor in the unit. That only applies where the building already has a chilled water plant with capacity to spare and a service agreement that guarantees it runs outside business hours, which is the usual catch in a commercial tenancy. Where the plant shuts down at night or on weekends, chilled water alone is not a safe basis for a critical room, and the ACW dual-fluid option or a DX selection is the better answer.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eModel tables: air cooled (A) and hybrid Free Cooling (GE)\u003c\/h2\u003e\n\n\u003cdiv style=\"overflow-x:auto;border-radius:8px;border:1px solid #2a2a2a;margin-bottom:24px;\"\u003e\n  \u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;line-height:1.4;\"\u003e\n    \u003ccaption style=\"caption-side:top;text-align:left;font-size:14px;color:#777777;padding:0 0 8px 2px;\"\u003eTable: CyberAir Mini air cooled DX models.

A 40 kVA three-phase UPS running at 60 per cent load at 95 per cent efficiency rejects only a couple of kilowatts of heat, not 40. Sizing on the nameplate is the single most common error we see, and it produces an oversized unit that short cycles, controls poorly and wears its compressor out early. Our \u003ca href=\"\/pages\/server-room-heat-load-calculator\" style=\"color:#d9590c;\"\u003eserver room heat load calculator\u003c\/a\u003e works this through properly, and we verify it against measured draw during a site visit.\u003c\/p\u003e\n\n\u003cp\u003eSecond, battery rooms are temperature-critical in a way server rooms are not. VRLA battery life halves for roughly every 8 to 10 degrees Celsius above 20 to 25 degrees Celsius. A battery string sitting at 35 degrees in an unconditioned room will not deliver its rated runtime and will need replacing in a fraction of its design life, which is a far larger cost than the cooling that would have prevented it. Holding the room at 20 to 25 degrees Celsius is the whole reason a battery room gets a precision unit rather than a wall split.\u003c\/p\u003e\n\n\u003cp\u003eThird, ventilation obligations apply. Vented lead-acid and some VRLA installations require mechanical ventilation to control hydrogen concentration, and where a mechanical ventilation system serves the space, AS\/NZS 3666 hygiene obligations for air handling apply alongside it. Cooling and ventilation need to be designed together, not bolted on in sequence. See our \u003ca href=\"\/pages\/server-room-ups-cooling-australia\" style=\"color:#d9590c;\"\u003eserver room UPS and cooling packages\u003c\/a\u003e for how we scope the two as one job.\u003c\/p\u003e\n\n\u003cp\u003eA practical rule for the small end: a 10 to 15 rack room with a UPS typically lands somewhere between 8 kW and 25 kW of sensible load once you account for lighting, envelope gain and people, which puts it squarely across the CCD 61 A to CCD 350 CW span. Two smaller units in N+1 are almost always a better answer than one larger unit, because a single unit means a single point of failure and no capacity to service the machine without shutting the room's cooling down entirely.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eFree Cooling and control options\u003c\/h2\u003e\n\n\u003cp\u003eBoth Direct and Indirect Free Cooling are available as options across the range. Direct Free Cooling draws filtered outside air into the room when conditions allow, which is the cheapest possible cooling but exposes the space to outside air quality. In coastal Australian locations, salt-laden air, and in summer, bushfire smoke, are real considerations that belong in the design conversation rather than being discovered later. Indirect Free Cooling keeps outside air out of the room entirely and rejects heat through a water or glycol circuit to an external dry cooler, with the integrated Free Cooling coil in the GE units doing the work whenever ambient conditions permit.\u003c\/p\u003e\n\n\u003cp\u003eOn chilled water selections, the pressure independent control valve option is worth specifying. It holds the design flow rate through the coil regardless of pressure fluctuations elsewhere in the building loop, which matters in a shared plant where other tenants' valves are constantly modulating. Paired with energy-efficient pumps it removes a class of control instability that is otherwise very hard to diagnose from inside the comms room.\u003c\/p\u003e\n\n\u003cp\u003eBeyond that, the option list covers different filter classes, various heating options and humidification. Filtration is specified to ISO 16890, and on a small room the filter is the component that most often causes a slow, unexplained loss of capacity. The STULZ controller flags filter condition, but it needs someone to be reading the alarms. The controller itself is available with an optional touchscreen and supports intelligent capacity control across a group of units, so an N+1 pair sequences rather than fighting each other.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eApplications\u003c\/h2\u003e\n\u003cul style=\"font-size:17px;padding-left:22px;margin-bottom:28px;\"\u003e\n  \u003cli style=\"margin-bottom:8px;\"\u003eSmall \u003ca href=\"\/pages\/server-room-cooling-australia\" style=\"color:#d9590c;\"\u003eserver rooms and comms rooms\u003c\/a\u003e from roughly four racks up to twenty, where a full data hall CRAC is oversized and a comfort split is unsuitable\u003c\/li\u003e\n  \u003cli style=\"margin-bottom:8px;\"\u003eUPS rooms and battery rooms needing a stable 20 to 25 degrees Celsius to protect battery design life, covered in our \u003ca href=\"\/pages\/server-room-ups-cooling-australia\" style=\"color:#d9590c;\"\u003eserver room UPS and cooling\u003c\/a\u003e packages\u003c\/li\u003e\n  \u003cli style=\"margin-bottom:8px;\"\u003eEquipment rooms, MDF and IDF rooms, and network riser rooms in commercial towers\u003c\/li\u003e\n  \u003cli style=\"margin-bottom:8px;\"\u003eRetrofits into existing buildings where the doorway, the ceiling height and the absence of a raised floor all constrain what can physically be installed\u003c\/li\u003e\n  \u003cli style=\"margin-bottom:8px;\"\u003eHospital, pathology and diagnostic imaging IT rooms with continuous uptime obligations\u003c\/li\u003e\n  \u003cli style=\"margin-bottom:8px;\"\u003eCouncil, utility, rail and defence control rooms operating under APRA CPS 230 style operational resilience expectations\u003c\/li\u003e\n  \u003cli style=\"margin-bottom:8px;\"\u003eBuildings on a central chilled water plant, where \u003ca href=\"\/pages\/chw-crac-maintenance-brisbane-sydney-melbourne\" style=\"color:#d9590c;\"\u003eCHW CRAC arrangements\u003c\/a\u003e or an ACW dual-fluid unit make the most sense\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eCyberAir Mini compared with Vertiv Liebert Mini-Mate\u003c\/h2\u003e\n\n\u003cdiv style=\"overflow-x:auto;border-radius:8px;border:1px solid #2a2a2a;margin-bottom:28px;\"\u003e\n  \u003ctable style=\"width:100%;border-collapse:collapse;font-size:15px;line-height:1.4;\"\u003e\n    \u003ccaption style=\"caption-side:top;text-align:left;font-size:14px;color:#777777;padding:0 0 8px 2px;\"\u003eTable: Indicative comparison against the nearest small-capacity Vertiv precision unit.

All electrical work must be carried out by a licensed electrician to AS\/NZS 3000, and any work on the refrigerant circuit requires an ARCtick licensed refrigeration technician under the Ozone Protection and Synthetic Greenhouse Gas Management Regulations. Where the unit forms part of a mechanical ventilation system, which is common in UPS and battery rooms, AS\/NZS 3666 hygiene obligations for air handling systems apply as well. Indigi carries out all three in house rather than subcontracting the critical path.\u003c\/p\u003e\n\n\u003cp\u003eA typical scope covers heat load verification against measured IT draw rather than nameplate ratings, condenser or dry cooler siting and pipe run design, rigging and placement into what is often a tight room with a single narrow door, refrigerant charging and leak testing, condensate drainage and pump-up where there is no gravity fall available, controller configuration and BMS integration, sequencing setup where two units run in N+1, and witness commissioning with a documented handover pack. Indicative pricing for server room cooling design and installation in the small band, which is where most CyberAir Mini projects sit, runs from $8,000 to $15,000. Medium installations run $25,000 to $45,000. Final scope always depends on the site, and condenser access is usually the variable that moves the number most.\u003c\/p\u003e\n\n\u003cp\u003eOnce running, a small room actually needs more maintenance discipline than a large one, not less, because there is rarely any redundancy to hide behind. The schedule should cover filter condition and replacement, coil cleanliness, condensate management, refrigerant charge and leak checks, compressor and EC fan health, humidifier service where fitted, and a review of the controller alarm history rather than just a glance at the current state.

Unlike a data centre CRAC unit it is designed for rooms with no or only a low heat load, where the job is holding a constant climate rather than removing kilowatts. Indigi Power and Cooling supplies, installs, commissions and maintains CyberLab units nationally from hubs in Brisbane, Sydney and Melbourne.\n  \u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cp\u003eMost precision cooling equipment sold in Australia is built around a problem that a laboratory store, a records repository or a collection store does not have. A data hall generates a large, continuous, almost entirely sensible heat load, and the machine that serves it is sized to move that heat out of the room fast. An archive stack, a herbarium cabinet room or a calibration lab often generates almost nothing. Lighting is minimal, occupancy is intermittent, and the equipment inside may amount to a few hundred watts. The risk in those rooms is not overheating. The risk is drift, and the material damage that follows when temperature and humidity wander outside the band the stored goods can tolerate.\u003c\/p\u003e\n\n\u003cp\u003eThe STULZ CyberLab is designed for exactly that case. STULZ describes it as the market's first standardised unit for special applications of this kind, meaning applications with no or only a low heat load, where the requirement is holding temperature and humidity constant so that sensitive stored goods do not deteriorate. It is a single standard size: 20.1 kW total cooling capacity, all of it sensible, 6,000 cubic metres per hour of airflow, 5.9 kW power consumption and 57 dBA sound pressure, quoted at return air of 24 degrees Celsius and 45 per cent relative humidity on a 400 V, three phase, 50 Hz supply with 50 Pa of external static pressure. Data at 60 Hz is available from STULZ on request. Air conduction is upflow and the cooling system is air cooled, with an external condenser, using R410A refrigerant at a global warming potential of 2,088.\u003c\/p\u003e\n\n\u003cp\u003eIndigi Power and Cooling is an Indigenous and Veteran owned critical power and cooling specialist, registered with Supply Nation and ICN Gateway. We supply, install, commission and maintain CyberLab units across Australia, including the humidification, condenser and controls scope that a close control installation depends on, and we can integrate the unit into an existing building management system alongside the rest of your critical plant.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eWhy a low heat load room is harder to control than a data hall\u003c\/h2\u003e\n\n\u003cp\u003eThis is counter intuitive to anyone whose experience is in data centre cooling, so it is worth setting out properly. A cooling machine only controls a room while it is actually running. In a data hall the load is large and constant, so the compressor runs continuously and the control loop has plenty of authority. Put the same machine in a 200 square metre archive stack with a 2 kW internal load and it will satisfy the setpoint in a few minutes, shut down, and then sit idle while the room slowly drifts back towards the conditions of the building around it. Every one of those cycles is a temperature excursion and, more importantly, a humidity excursion.\u003c\/p\u003e\n\n\u003cp\u003eHumidity is where the damage happens. Paper, parchment, textiles, timber, photographic emulsion, herbarium sheets, taxidermy, magnetic tape and pharmaceutical products all respond to relative humidity far more sharply than they respond to temperature. Cyclic swings are worse than a steady value slightly off target, because repeated moisture uptake and release drives dimensional movement, cockling, delamination and, at the upper end, mould germination. A specification that reads 20 degrees Celsius and 50 per cent relative humidity is really a specification about stability, not about the numbers themselves.\u003c\/p\u003e\n\n\u003cp\u003eA conventional CRAC unit makes this worse in two specific ways. First, it dehumidifies whether you want it to or not. Whenever the coil surface sits below the dew point of the return air, moisture condenses out, so a machine that is oversized for the sensible load strips water out of a room that had no latent load to begin with, and the humidity floor keeps dropping. Second, its capacity steps are coarse. A unit with two on\/off compressors serving a small load has very little useful modulation available, so it hunts.\u003c\/p\u003e\n\n\u003cp\u003eThe CyberLab is built the other way round. Its cooling capacity is fully sensible, so the sensible heat ratio is effectively 1.0 and the coil is not designed to be a dehumidifier. Its EC compressor modulates infinitely across an output control range of 0 to 100 per cent, so it can sit at a low, steady output indefinitely rather than cycling.

AS\/NZS 3666 is built around the same logic as VDI 6022: cooling coils, drain pans and condensate systems are the components where microbial amplification occurs, so they must be accessible, inspectable and cleanable, and they must be inspected on a defined schedule. Part 2 of the standard sets out the operation and maintenance regime, including the requirement that plant is designed so that inspection can actually be carried out.\u003c\/p\u003e\n\n\u003cp\u003eThis matters more than it sounds. In practice the most common AS\/NZS 3666 finding on close control equipment is not that the drain pan is dirty, it is that nobody can see whether the drain pan is dirty without a shutdown, so the inspection either does not happen or happens once a year with the unit off. Four factory fitted inspection windows change the economics of that inspection completely. A facilities officer can walk past on a Monday morning, look through the glass, and record a visual condition check without touching the plant or interrupting the climate in the room. For a hospital laboratory, a PC2 suite or a public collection store, that is a real compliance advantage rather than a marketing point.\u003c\/p\u003e\n\n\u003cp\u003eThe same design thinking runs through the rest of the airstream. The condensate tray is arranged to drain fully rather than hold standing water, the heat exchanger is accessible for cleaning, and because the unit runs continuously at low modulated output instead of cycling on and off, the coil spends far less time sitting wet and idle, which is the condition microbial growth actually needs.

Holding relative humidity to plus or minus 3 per cent means being able to add moisture as well as remove it, and in most Australian climates a sealed store will need humidification for a meaningful part of the year. Perth, Adelaide, Canberra and inland New South Wales all run long dry spells where an unhumidified room will sit well below any sensible collection or laboratory setpoint.\u003c\/p\u003e\n\n\u003cp\u003eThe CyberLab uses an external STULZ UltraSonic BNB ultrasonic humidifier, controlled directly by the CyberLab controller rather than by a separate standalone humidistat. Ultrasonic humidification works by using piezoelectric oscillators to atomise water into a fine cold mist, which is then carried into the airstream. Compared with an electrode boiler or resistive steam humidifier, the electrical demand is very low for the moisture delivered, there is no boiling cylinder to replace, and there is no heat added to a room that is being cooled at the same time. The trade off is that ultrasonic units require good water quality, so water treatment should be specified at design stage rather than retrofitted after the first service.\u003c\/p\u003e\n\n\u003cdiv style=\"overflow-x:auto;border-radius:8px;border:1px solid #2a2a2a;margin-bottom:28px;\"\u003e\n  \u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;line-height:1.4;\"\u003e\n    \u003ccaption style=\"caption-side:top;text-align:left;font-size:14px;color:#777777;padding:0 0 8px 2px;\"\u003eTable: STULZ UltraSonic BNB external humidifier options for the CyberLab.

A well sealed, vapour checked archive with minimal air change may sit comfortably on a BNB 5000A at 5.0 kg per hour. A gallery store with a loading airlock, regular door openings and staff access, or a laboratory with mechanical exhaust that has to be made up, will usually need the 8.0 kg per hour BNB 8000A. Both units are slim, at 255 mm high and 200 mm deep, so they mount on a wall or in a duct without taking usable floor space out of a store.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eEC compressor control and the STULZ C7000\u003c\/h2\u003e\n\n\u003cp\u003eThe infinitely variable EC compressor is the component that makes the control accuracy achievable. STULZ lists five benefits of it on this unit and each one has a direct consequence for a low load room. Infinite compressor control gives precise temperature regulation. Maximum efficiency in partial load matters because a room like this is in partial load essentially all of the time, so the part load figure is the real operating figure, not the nameplate. A constant supply air temperature means the air leaving the unit does not swing between cold and neutral, which is what causes localised humidity variation across a store. Integrated soft start protects the power line by removing the large inrush current of a direct on line compressor start. And the long service life comes from continuous operation without on\/off cycles, since compressor wear is concentrated in starts rather than in running hours.\u003c\/p\u003e\n\n\u003cp\u003eEvery component in the system, including the external UltraSonic humidifier, is controlled by the STULZ C7000. Having one controller manage cooling, dehumidification and humidification together is not a convenience feature. When those functions are split between separate devices, the classic failure mode is a control loop fight: the cooling coil pulls moisture out below the dew point while the humidifier puts it back in, and the room holds setpoint while both devices run continuously and the energy bill quietly doubles. A single controller with visibility of both temperature and humidity can sequence them properly and use a dead band, so only one of them acts at a time.\u003c\/p\u003e\n\n\u003cp\u003eThe C7000 is a familiar unit to Australian refrigeration and controls technicians because it is fitted across a wide range of STULZ equipment, not just the CyberLab. Operating parameters, setpoints, alarm history and operating hours are all reachable from the front panel display. Deeper configuration menus are password protected by service level, which is the correct arrangement for a controller in a room where an unrecorded setpoint change can damage a collection. Indigi technicians hold the service access required to commission, reconfigure and fault find on C7000 equipped units, and we document every parameter change as part of the service report rather than leaving it in the controller for the next person to discover.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eAustralian applications\u003c\/h2\u003e\n\n\u003cp\u003eThese buyers care about humidity stability far more than raw cooling capacity, which is the opposite of a data centre buyer.

That log is also the baseline for every subsequent service visit, so drift can be identified as a trend rather than discovered as a failure.\u003c\/p\u003e\n\n\u003cp\u003eOngoing maintenance follows the same continuous duty logic as any critical cooling asset, with two additions. The hygiene inspection through the four windows should be recorded at every visit and, ideally, more often by site staff between visits. And the ultrasonic humidifier needs water quality checks, oscillator condition checks and cleaning on a schedule set by the local water supply. Everything else is familiar: coil condition, condensate management, refrigerant charge, fan and compressor health, filter condition and a controller alarm history review.

Combined with the manufacturer's worldwide service network and Indigi's Australian coverage, that gives a defensible chain of evidence for an institution that has to justify the spend on a collection or a laboratory it is legally responsible for.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eFrequently asked questions\u003c\/h2\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eWhat is the STULZ CyberLab used for?\u003c\/h3\u003e\n\u003cp\u003eThe CyberLab is a precision air conditioning unit for maintaining a constant climate in archives, warehouses, museums and laboratories. It is designed for applications with no or only a low heat load, where the requirement is holding temperature and humidity constant so that sensitive stored goods do not deteriorate. STULZ describes it as the market's first standardised unit for special applications of this kind. Typical Australian uses are records repositories, gallery and museum collection stores, herbaria and seed banks, pathology and specimen storage, calibration rooms and wine storage.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eHow accurately does the CyberLab control temperature and humidity?\u003c\/h3\u003e\n\u003cp\u003eTemperature is held to within plus or minus 0.5 K of setpoint and relative humidity to within plus or minus 3 per cent. That accuracy comes from three things working together: an infinitely variable EC compressor with an output control range of 0 to 100 per cent, fully sensible cooling capacity so the coil is not dehumidifying uncontrolled, and a single STULZ C7000 controller managing cooling, dehumidification and the external humidifier as one system.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eWhat cooling capacity does the STULZ CyberLab provide?\u003c\/h3\u003e\n\u003cp\u003eTotal cooling capacity is 20.1 kW, all of it sensible, at an airflow of 6,000 cubic metres per hour and a power consumption of 5.9 kW. Sound pressure is 57 dBA measured at 1 m height and 2 m in front of the unit under free field conditions. External static pressure is 50 Pa as standard and 450 Pa maximum. These are nominal figures at return air of 24 degrees Celsius and 45 per cent relative humidity on a 400 V, three phase, 50 Hz supply with 50 Pa external static pressure, and 60 Hz data is available from STULZ on request.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eWhy does the CyberLab have inspection windows?\u003c\/h3\u003e\n\u003cp\u003eThe CyberLab is designed to comply with VDI 6022 hygiene requirements, and to satisfy those requirements the units are fitted with four inspection windows. They let you check the condition of the condensate tray and the heat exchanger at any time and so prevent bacterial growth. In Australia the equivalent standard is AS\/NZS 3666, covering air handling and water systems of buildings and their microbial control, which requires that coils, drain pans and condensate systems can actually be inspected and cleaned. The windows make that inspection possible without shutting the unit down or removing panels.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eWhich humidifier is used with the CyberLab?\u003c\/h3\u003e\n\u003cp\u003eAn external STULZ UltraSonic BNB ultrasonic humidifier, controlled by the CyberLab controller. Two sizes are offered. The BNB 5000A delivers 5.0 kg per hour of humidifying output from 10 oscillators, draws 430 VA and measures 694 by 255 by 200 mm. The BNB 8000A delivers 8.0 kg per hour from 16 oscillators, draws 670 VA and measures 1,024 by 255 by 200 mm. Selection depends on the moisture loss rate of the room, not its floor area, so air change rate, door openings and any mechanical exhaust make up all need to be counted.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eWhat is the STULZ C7000 controller?\u003c\/h3\u003e\n\u003cp\u003eThe C7000 is the STULZ unit controller fitted to the CyberLab and to a wide range of other STULZ equipment. On this product it controls all components in the system, including the external UltraSonic humidifier, so cooling, dehumidification and humidification are sequenced by one device rather than by separate controls that can work against each other. Setpoints, operating hours and alarm history are available from the front panel display, while deeper configuration menus are password protected by service level.

The CyberLab is built for continuous low output, fully sensible cooling, tight humidity control and permanent hygiene inspection access.\"}}\n]}\n\u003c\/script\u003e","brand":"STULZ","offers":[{"title":"Default Title","offer_id":52961636843840,"sku":null,"price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/8375\/5840\/files\/CyberLab_800x800px.jpg?v=1786195505"},{"product_id":"stulz-cabinetair-prt-outdoor-cabinet-cooling-australia","title":"STULZ CabinetAir PRT Outdoor Cabinet Cooling Units Australia","description":"\u003cdiv style=\"box-sizing:border-box;max-width:960px;margin:0 auto;padding:28px 20px;font-family:Arial,Helvetica,sans-serif;font-size:17px;line-height:1.6;color:#222222;\"\u003e\n\n\u003cp style=\"font-size:15px;color:#888888;text-transform:uppercase;letter-spacing:0.5px;margin:0 0 10px 0;\"\u003eHome \/ Precision Cooling \/ STULZ \/ CabinetAir PRT\u003c\/p\u003e\n\n\u003cdiv style=\"background-color:#fafafa;border-left:4px solid #d9590c;border-radius:6px;padding:16px 20px;margin-bottom:28px;\"\u003e\n  \u003cp style=\"margin:0;font-size:19px;\"\u003e\n    \u003cstrong\u003eThe STULZ CabinetAir PRT is a 1.0 kW to 2.0 kW Plug and Play cooling unit for a single outdoor equipment cabinet, built to hold street and roadside enclosures within their operating temperature anywhere in Australia.\u003c\/strong\u003e\n    Three models cover the range, PRT10H at 1.0 kW, PRT14H at 1.4 kW and PRT20H at 2.0 kW, all in the same 1,200 mm high by 417 mm wide by 300 mm deep envelope, running on R134a and rated by STULZ for outside temperatures from -20 to +60 degrees Celsius. Indigi Power and Cooling supplies, installs and maintains CabinetAir PRT units nationally from hubs in Brisbane, Sydney and Melbourne.\n  \u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cp\u003eAn outdoor equipment cabinet is a small, sealed, uninsulated steel box sitting in the open. The electronics inside it dissipate perhaps a few hundred watts to a couple of kilowatts, which does not sound like much until you add the solar gain on a dark cabinet skin in full sun and remember that there is nowhere for the heat to go. The CabinetAir PRT is the STULZ answer to exactly that problem. It is by a wide margin the smallest unit in the STULZ outdoor cooling family, an order of magnitude below the shelter and container units, and it is scoped for one cabinet rather than a room, a shelter or a walk-in enclosure.\u003c\/p\u003e\n\n\u003cp\u003eAustralian conditions make the case sharper than most markets. A kerbside cabinet in Bourke, Mount Isa or the Pilbara sees ambient air that already sits close to the internal temperature limit of the equipment before the equipment has produced any heat of its own, and the cabinet skin itself can run well above ambient in direct sun. STULZ rates the CabinetAir PRT for outside temperatures up to +60 degrees Celsius, which is higher than the rest of the STULZ shelter range and is the single specification on this page that matters most to an Australian roadside deployment. At the other end of the map, a cabinet in a residential street in suburban Melbourne has a different constraint entirely, which is that whatever cools it has to be quiet enough that nobody complains about it.\u003c\/p\u003e\n\n\u003cp\u003eIndigi Power and Cooling is an Indigenous and Veteran owned critical power and cooling specialist, registered with Supply Nation and ICN Gateway. We supply, install, commission and maintain STULZ cabinet cooling across Australia, and we work with network operators who run fleets of enclosures rather than single sites, so the conversation usually starts with how the maintenance model will scale rather than with the unit itself.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eSee STULZ outdoor cooling in operation\u003c\/h2\u003e\n\n\u003cdiv style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;border-radius:8px;margin-bottom:10px;background:#111111;\"\u003e\n  \u003ciframe src=\"https:\/\/www.youtube.com\/embed\/-fzfhYF0uiE\" title=\"STULZ Shelter Cooling (english)\" frameborder=\"0\" loading=\"lazy\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0;\"\u003e\u003c\/iframe\u003e\n\u003c\/div\u003e\n\u003cp style=\"font-size:14px;color:#888888;margin:0 0 28px 0;\"\u003eSTULZ Shelter Cooling (english), 2 minutes 47 seconds.

Whenever the outside air is cool enough to carry the cabinet's heat away on its own, the unit uses it directly and the compressor stays off. The only electrical load in that mode is fan power, which is a small fraction of what a compressor draws. When the outside air is too warm to do the job, the unit reverts to active air conditioning and holds the internal temperature regardless. STULZ positions this as huge energy savings, and on a cabinet running a constant electronics load year round the saving accrues every hour that the ambient sits below the internal setpoint.\u003c\/p\u003e\n\n\u003cp\u003eWhere that lands in Australia depends heavily on latitude. A cabinet in Hobart, Canberra, Ballarat or the New South Wales tablelands spends a large share of the year with ambient air well below the cabinet setpoint, so the compressor is idle for most of the annual hours. A cabinet in Darwin, Cairns or Karratha spends far less time in that window, and the case for the unit there rests on the active cooling capability and the +60 degrees Celsius outside rating rather than on the Free Cooling hours. Both cases are legitimate, they are just different business cases, and it is worth being honest about which one applies before the energy saving goes into a submission.\u003c\/p\u003e\n\n\u003cp\u003eThe trade-off with any direct method is that outside air is being brought to the equipment rather than kept away from it, so filtration and filter servicing become part of the operating plan. On a dusty rural highway, a road corridor under construction, or a coastal site with salt laden air, that is a real consideration and should be raised at design stage rather than discovered at the first blocked filter. Where the enclosure genuinely cannot tolerate any outside air, the unit still functions as a conventional active cooling module, you simply do not collect the Free Cooling hours.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eFull capacity in all operating conditions\u003c\/h2\u003e\n\n\u003cp\u003eSTULZ states that with the CabinetAir PRT the system equipment can run at 100 per cent capacity in all operating conditions, so there are no fluctuations in the performance of the IT components inside the cabinet. That claim is worth unpacking, because it is the practical difference between an active cooling unit and everything cheaper.\u003c\/p\u003e\n\n\u003cp\u003ePassive and semi-passive cooling methods are all tied to ambient. A filtered fan set can only ever hold the cabinet above outside air temperature, so on a 42 degree afternoon the internal temperature is somewhere north of 42 degrees and the equipment inside either throttles, drops carriers, restarts, or ages faster than the asset plan assumed. A thermoelectric cooler can get below ambient, but the margin it can hold shrinks as the outside temperature climbs, which is precisely when you need it. Active refrigeration is indifferent to that. It sets the internal condition and holds it, and the +60 degrees Celsius upper limit means that limit is not going to be reached by an Australian summer, however unpleasant the day is at kerb level.\u003c\/p\u003e\n\n\u003cp\u003eFor a network operator the consequence is not really a temperature number, it is a fault statistic. Thermal derating events on radio and transmission equipment are usually invisible in the asset register and highly visible in the network performance report. Removing the temperature variable removes a category of intermittent fault that is expensive to diagnose from the network operations centre because it does not reproduce on a cool morning.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003ePlug and Play mounting and the swap-out maintenance model\u003c\/h2\u003e\n\n\u003cp\u003eThis is the part of the CabinetAir PRT story that carries the most commercial weight in Australia, and it is also the part that gets overstated most often, so it is worth setting out precisely.\u003c\/p\u003e\n\n\u003cp\u003eThe unit is a self-contained, factory sealed and factory charged module. It mounts to the cabinet and it comes off the same way. STULZ states that units can be serviced and replaced by the operator's own personnel with no refrigeration engineers required. The mechanism behind that statement is straightforward: because the module is exchanged as a whole rather than opened, the refrigerant circuit is never broken into during a routine swap, so the person doing the exchange is not performing refrigerant handling work. An operator's own field technician can carry the replacement unit to site, disconnect and remove the failed module, mount and reconnect the replacement, and be gone, without a separate refrigeration callout being scheduled behind them.\u003c\/p\u003e\n\n\u003cp\u003eWhat that does not mean is that the regulations stop applying. Any work that does involve the refrigerant circuit, including recovery, charging, leak repair, and degassing the removed module at end of life, still requires an ARCtick licensed technician under the Ozone Protection and Synthetic Greenhouse Gas Management Regulations. Electrical connection of the unit still requires a licensed electrician working to AS\/NZS 3000. The saving is specific and it is real, but it is a saving on routine swap-outs, not an exemption. Written accurately in a maintenance plan it still stands up, and it is far more defensible than a claim that the unit needs no licensed trades at all.\u003c\/p\u003e\n\n\u003cp\u003eThe value of that model scales with fleet size and geography, which is exactly the shape of most Australian street cabinet estates. If you have four hundred enclosures spread across a state, the cost of every intervention is dominated by travel and by the number of separate trades that have to attend. Collapsing a cooling failure from a two visit, two trade event into a single technician visit with a replacement module in the back of the van is the whole argument. It also means a failed unit can be returned to a workshop and assessed properly instead of being diagnosed at the kerb with traffic control in place.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eMonitoring, alarms and what to specify\u003c\/h2\u003e\n\n\u003cp\u003eA street cabinet is unattended by definition, so the cooling unit needs to be able to tell somebody when it is unhappy. Specify the monitoring interface at order stage rather than after the first summer. The practical questions are whether the unit can raise a volt free alarm contact into the existing site alarm loop, whether internal cabinet temperature can be reported back to the network management system alongside the equipment alarms already coming from that site, and whether the alarm thresholds can be set to something that gives useful warning rather than only reporting a failure that has already happened.\u003c\/p\u003e\n\n\u003cp\u003eSet the high temperature warning threshold below the point at which the equipment inside starts to derate, not at its shutdown limit, so a truck roll can be planned in business hours. Indigi will walk through the available options with STULZ for the specific configuration you are ordering, because what is offered varies by model and by order code and we would rather quote what is actually available than what would be convenient.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eAustralian applications\u003c\/h2\u003e\n\u003cul style=\"font-size:17px;padding-left:22px;margin-bottom:28px;\"\u003e\n  \u003cli style=\"margin-bottom:8px;\"\u003eNBN and telecommunications street cabinets in residential and commercial streets, where noise and appearance both matter\u003c\/li\u003e\n  \u003cli style=\"margin-bottom:8px;\"\u003eFibre distribution and node cabinets carrying active electronics that must not thermally derate\u003c\/li\u003e\n  \u003cli style=\"margin-bottom:8px;\"\u003eKerbside and roadside equipment enclosures exposed to full sun for most of the day\u003c\/li\u003e\n  \u003cli style=\"margin-bottom:8px;\"\u003eTraffic signal and intelligent transport system controller cabinets at intersections and on motorway corridors\u003c\/li\u003e\n  \u003cli style=\"margin-bottom:8px;\"\u003eRail level crossing, signalling and trackside equipment cabinets, including remote sections with long response times\u003c\/li\u003e\n  \u003cli style=\"margin-bottom:8px;\"\u003eSmall cell and distributed antenna system equipment enclosures on poles, rooftops and street furniture\u003c\/li\u003e\n  \u003cli style=\"margin-bottom:8px;\"\u003eUtility metering, RTU and SCADA cabinets across electricity, water and gas networks\u003c\/li\u003e\n  \u003cli style=\"margin-bottom:8px;\"\u003eCCTV, public safety and emergency communications enclosures in public places\u003c\/li\u003e\n  \u003cli style=\"margin-bottom:8px;\"\u003eEdge compute and micro node cabinets that sit outside the scope of a conventional \u003ca href=\"\/pages\/server-room-cooling-australia\" style=\"color:#d9590c;\"\u003eserver room cooling\u003c\/a\u003e design but still carry a continuous IT load\u003c\/li\u003e\n  \u003cli style=\"margin-bottom:8px;\"\u003eSites where the cabinet also houses batteries or a small inverter, which is worth reviewing alongside \u003ca href=\"\/pages\/server-room-ups-cooling-australia\" style=\"color:#d9590c;\"\u003eUPS and cooling packages\u003c\/a\u003e because battery life is temperature driven\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eTwo Australian conditions come up on almost every one of these.

Roadside enclosures get hit by mowers, water, dust, wind driven rain and occasional deliberate damage, and any cooling arrangement that depends on a fragile external component will generate callouts.

Any work on the refrigerant circuit requires an ARCtick licensed refrigeration technician under the Ozone Protection and Synthetic Greenhouse Gas Management Regulations, and that includes recovering the R134a charge from a module that is being retired. AS\/NZS 3666 governs the microbial control of air handling and water systems in buildings, so it will not normally be triggered by a standalone street cabinet, but it does come into scope where the same maintenance contract also covers building mounted mechanical ventilation plant, and it is worth checking which of your sites fall on which side of that line before the contract is written.\u003c\/p\u003e\n\n\u003cp\u003eA typical scope for us covers heat load verification against the actual equipment draw in the cabinet rather than the nameplate, a review of solar exposure and orientation at the specific site, confirmation of the cabinet cut-out and mounting arrangement, electrical supply and protection, condensate management, alarm and monitoring integration, and a documented commissioning record for each enclosure so that the fleet has a baseline to measure against.

The existing unit stays where it is and keeps its role as the guaranteed cooling source, while the ShelterAir FC uses filtered outside air to carry part of the annual load whenever ambient conditions allow. Indigi Power and Cooling supplies, installs, commissions and maintains ShelterAir FC retrofits nationally from hubs in Brisbane, Sydney and Melbourne.\n  \u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cp\u003eMost of the shelter cooling market is about buying a new air conditioner. This product is not. The ShelterAir FC is described by STULZ as a retrofit container cooling unit for indoor or outdoor installation, and the reason it exists is stated plainly on the product page: to considerably cut the running costs of base stations, they can be retrofitted with the STULZ ShelterAir FC Free Cooling unit. The incumbent comfort air conditioner is not removed, not rewired out of service, and not written off. It stays installed and remains the fallback whenever outside air cannot do the job.\u003c\/p\u003e\n\n\u003cp\u003eThat distinction matters commercially far more than it looks on paper. An Australian carrier, electricity distributor, water authority or rail operator does not own one shelter. It owns hundreds, sometimes thousands, each with a working air conditioner that was capitalised years ago and still has service life left in it. Replacing that fleet is a capital program measured in years and millions. Bolting a Free Cooling module onto each shelter is a per site job that can be scheduled around normal maintenance rounds, and the energy saving lands against the asset base that already exists rather than waiting on a replacement cycle.\u003c\/p\u003e\n\n\u003cp\u003eIndigi Power and Cooling is an Indigenous and Veteran owned critical power and cooling specialist, registered with Supply Nation and ICN Gateway.

Air conditioning a shelter with a compressor means paying to move heat uphill against the outside temperature. Free Cooling means using outside air directly, when the outside air is cold enough to be useful, and paying only for fan power to move it. A Free Cooling module is therefore a fan, a filter, a damper arrangement and a controller. There is no compressor in it and it is not trying to replace one.\u003c\/p\u003e\n\n\u003cp\u003eThe ShelterAir FC sits alongside the incumbent air conditioner and shares the same room. The controller watches the outside temperature and the inside temperature. When the outside air is below the changeover point you have configured, the module opens, the fan moves 5,400 cubic metres per hour of filtered outside air through the shelter, and the compressor on the incumbent unit does not need to start. When the outside air rises above the changeover point, the module closes and the incumbent unit resumes exactly the duty it performed before the retrofit. Nothing about the fallback position changes, which is why the retrofit does not alter the site risk profile.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 10px 0;\"\u003eThe changeover point is the single most important setting\u003c\/h3\u003e\n\n\u003cp\u003eSTULZ lists as a key feature that the outside temperature value at which Free Cooling starts can be defined as you wish. That flexibility is not a marketing line, it is the whole engineering argument for deploying one product across a national fleet. A shelter in Ballarat and a shelter in Rockhampton have completely different ambient profiles, and a fixed factory changeover temperature would be either too conservative in the south or useless in the north.\u003c\/p\u003e\n\n\u003cp\u003eThe setting is a trade between two things. Set it high, closer to the temperature you are willing to let the shelter reach, and you capture more Free Cooling hours per year but run the shelter warmer for more of the time. Set it low and the shelter stays cooler but the module contributes fewer hours. The right answer depends on what the equipment inside will tolerate. Telecommunications hardware in a base station is generally specified for a wider envelope than IT equipment in a data hall, where ASHRAE TC 9.9 recommends 18 to 27 degrees Celsius at the inlet. Where a shelter contains both, the tighter of the two envelopes governs, and the changeover point should be set accordingly.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 10px 0;\"\u003eBackup operation when the mains supply fails\u003c\/h3\u003e\n\n\u003cp\u003eSTULZ lists backup operation, covering Free Cooling and backup cooling, on failure of the main power supply. This is a genuinely useful property in the Australian remote site context. A telecommunications shelter usually holds a battery string or a DC power system sized to keep the radio equipment alive through an outage, but not sized to keep a compressor running. Cooling is often the first thing to drop off, and the shelter then heats up on the back of the load it is still carrying. A Free Cooling module draws only fan power, which is a far smaller demand, so it can keep moving air when full mechanical cooling cannot be sustained. In a summer storm outage in regional Queensland or New South Wales, that difference decides whether the site rides through or thermally trips.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 10px 0;\"\u003eMonitoring and remote access matter more on a fleet\u003c\/h3\u003e\n\n\u003cp\u003eOn a single site, you can walk in and read the controller. On four hundred sites, you cannot. The ShelterAir FC offers connectivity with monitoring and remote access via a web interface, and on a retrofit program that is the mechanism that turns a claimed saving into a demonstrated one. If a damper sticks, a filter blocks or a changeover setpoint gets left at the factory default after a site visit, the module quietly stops contributing and the incumbent air conditioner picks up the whole load again. Nothing fails, nothing alarms at the network operations centre, and the energy saving simply evaporates. Remote visibility is how you catch that.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eThe commercial case for retrofitting an existing shelter fleet\u003c\/h2\u003e\n\n\u003cp\u003eThis is the part that decides whether a Free Cooling retrofit gets funded, so it is worth setting out honestly rather than optimistically.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 10px 0;\"\u003eThe capital argument\u003c\/h3\u003e\n\n\u003cp\u003eTake a typical Australian carrier, distribution network service provider, water authority or rail operator. It has a large installed base of shelters, huts and roadside cabinets. Each one already has a working comfort air conditioner in it, often a wall mounted split or a purpose built shelter unit, and that asset was capitalised at some point in the past and still has years of service life left. Replacing all of them is capital intensive, slow to schedule and disruptive to sites that carry live services. It is also hard to justify to a board when the existing units are not actually failing.\u003c\/p\u003e\n\n\u003cp\u003eA Free Cooling retrofit changes the shape of the proposal. Instead of a replacement program, it is an efficiency program. Outside air carries part of the annual cooling load without touching the incumbent unit, so the saving lands against the asset base the organisation already owns. The existing air conditioner keeps running, keeps its remaining book value, and keeps being the guaranteed cooling source on the hot days when outside air is no use. The work per site is a mounting job, an aperture, a power connection and a controller integration rather than a plant replacement, so it can be batched into existing maintenance rounds and rolled out region by region.\u003c\/p\u003e\n\n\u003cp\u003eThere is a second order benefit that is easy to overlook. Every hour the compressor on the incumbent unit does not run is an hour of wear it does not accumulate. Compressor starts and run hours are the dominant driver of shelter air conditioner failure, so shifting hours to a fan based mode tends to extend the incumbent unit's remaining life, which pushes the replacement decision further out again.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 10px 0;\"\u003eWhere the retrofit pays back fastest in Australia\u003c\/h3\u003e\n\n\u003cp\u003eFree Cooling is worth exactly as many hours per year as the local climate gives it, so the business case is climate dependent and there is no national answer. The sites that repay a retrofit fastest are inland and southern, with cool nights and a large diurnal swing. Regional Victoria, the Southern Tablelands and the Central West of New South Wales, Tasmania, the Adelaide Hills and inland South Australia all give long stretches of the year where night time and shoulder season outside air sits well below any sensible changeover point. Because base stations and equipment huts run a flat load around the clock, overnight Free Cooling hours are just as valuable as daytime ones, which favours the big diurnal swing sites strongly.\u003c\/p\u003e\n\n\u003cp\u003eHigh altitude and elevated inland sites also do well. A shelter on a ridge line in the Great Dividing Range sees materially cooler ambient conditions than a coastal site at the same latitude, and those sites are common in both carrier and emergency services networks.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 10px 0;\"\u003eWhere it pays back slowest, and where we will say so\u003c\/h3\u003e\n\n\u003cp\u003eHumid tropical sites are the weak case and it is better to hear that before the purchase order than after. In Darwin, Cairns, Townsville and across the Top End, outside air is rarely cool enough or dry enough to be usable for a meaningful number of hours, and overnight temperatures stay high through the wet season. A Free Cooling module fitted there may run for so few hours a year that it never repays the install cost. The same caution applies, less severely, to humid coastal sites elsewhere, and coastal salt laden air is a separate consideration for filter loading and corrosion.\u003c\/p\u003e\n\n\u003cp\u003eThe STULZ source material does not publish a payback period or a savings percentage for the ShelterAir FC, and we will not invent one. Anyone quoting you a fleet wide percentage without having looked at your ambient data, your shelter thermal envelope, your internal load and your temperature tolerance is guessing. The correct next step is a site assessment on a representative sample of shelters across your climate zones, which is what tells you which parts of the fleet are worth retrofitting and which parts are not.

Electrical connection and any change to the shelter distribution board must be carried out by a licensed electrician to AS\/NZS 3000. Where the retrofit involves working on the refrigerant circuit of the incumbent air conditioner, for example relocating it, isolating it or reconnecting it around the new aperture, that work requires an ARCtick licensed refrigeration technician under the Ozone Protection and Synthetic Greenhouse Gas Management Regulations. Because the module introduces outside air into an occupiable space through a mechanical ventilation path, AS\/NZS 3666 hygiene obligations apply to the filter and air handling arrangement. Indigi holds these capabilities in house rather than subcontracting the critical path.\u003c\/p\u003e\n\n\u003cp\u003eTypical retrofit scope covers a site survey and thermal assessment of the shelter, confirmation that the incumbent unit is sound enough to be worth retaining, selection between an FCL outdoor and an FCL-IN indoor unit against the available wall area and internal clearance, cutting and weatherproofing the aperture, mounting and sealing, electrical connection, controller integration with the existing comfort unit so the two do not fight each other, setting the Free Cooling changeover point for the site's climate zone, connecting the web interface for remote monitoring, and a documented commissioning record per site. On a fleet rollout we also recommend a pilot batch across two or three climate zones before the full program is committed.\u003c\/p\u003e\n\n\u003cp\u003ePricing depends entirely on scope and site count, and a single shelter retrofit sits well below a full room installation. For context, our indicative pricing for server room cooling design and installation runs from $8,000 to $15,000 for small rooms, $25,000 to $45,000 for medium installations and $45,000 to $60,000 plus for large projects.

Filters are the single biggest determinant of whether the module keeps delivering, because a blocked filter quietly reduces Free Cooling airflow until the incumbent compressor is carrying the load again. Dampers and actuators need checking, sensors need verifying against a reference so the changeover point is acting on a true reading, and the alarm and event history should be reviewed remotely between site visits.

STULZ describes it as a retrofit container cooling unit for indoor or outdoor installation, fitted to base stations so that outside air carries part of the cooling load and the running cost of the site falls. It delivers 3.5 kW to 15.0 kW at 5,400 cubic metres per hour across three sizes and five model variants.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eCan the ShelterAir FC be fitted to an air conditioner that is already installed?\u003c\/h3\u003e\n\u003cp\u003eYes. That is the entire purpose of the product. STULZ lists simple integration into existing comfort air conditioning units as a key feature, and lists the Free Cooling system as one that can be retrofitted into existing systems. The incumbent unit is not removed and continues to provide guaranteed cooling whenever outside air is too warm to be usable.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eWhat is the difference between FCL and FCL-IN?\u003c\/h3\u003e\n\u003cp\u003eFCL is the version for outdoor installation, mounted on the outside of the shelter, and is available as FCL 35 at 3.5 kW and FCL 60 at 6.0 kW, both in size 2 at 720 x 612 x 604 mm. FCL-IN is the version for indoor installation and is available as FCL-IN 35 and FCL-IN 60 in size 1 at 640 x 1,271 x 289 mm, plus FCL-IN 70 at 15.0 kW in size 3 at 600 x 1,250 x 600 mm.

The saving is proportional to the number of hours per year that outside air is below your changeover point, which makes it strongly climate dependent. Cool inland and southern sites with large diurnal swings, such as regional Victoria, the Southern Tablelands, the Central West, Tasmania and inland South Australia, do best. Humid tropical sites such as Darwin and Cairns do worst, because outside air is rarely usable.

STULZ rates the Direct Free Cooling function at up to 83 per cent savings on running costs, and the unit will keep running on 48 V DC or 230 V single phase backup when the main supply fails.\n  \u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cp\u003eA telecommunication container, a rail signalling hut or a base station shelter is a small sealed box with a continuous heat load and nobody in it. That combination is unforgiving. The equipment inside runs every hour of every year, the enclosure has almost no thermal mass, and if the cooling stops the internal temperature climbs fast enough to trip battery chargers, transmission gear and edge compute nodes within an hour. The SplitAir is built for exactly that duty, and it is the split system member of the STULZ shelter cooling family.\u003c\/p\u003e\n\n\u003cp\u003eThe split arrangement is the point of difference. Rather than one box that carries evaporator, compressor and condenser together, the SplitAir separates the indoor evaporator unit from an outdoor condensing unit connected by a refrigerant line set. That matters in two situations that come up constantly in Australia. The first is a retrofit, where an existing container has cable trays, battery racks or a distribution board occupying the wall where a full depth unit would have to go, and the only viable indoor footprint is 350 mm to 410 mm deep. The second is an aesthetics or security constraint, where a council, a landlord or a site owner will not accept a large penetration and a bulky unit hanging off the outside face of the shelter, but will accept a condensing unit sitting on a plinth or a bracket at ground level.\u003c\/p\u003e\n\n\u003cp\u003eIndigi Power and Cooling is an Indigenous and Veteran owned critical power and cooling specialist, registered with Supply Nation and ICN Gateway.

Instead of running the compressor whenever the shelter is above setpoint, the SplitAir opens a damper and pulls filtered outside air through the enclosure whenever the outside air is cold enough to carry the heat load on its own. The compressor stays off. Fan power replaces compressor power, and fan power on a unit of this size is a small fraction of it. STULZ rates the result at up to 83 per cent savings on running costs compared with mechanical cooling alone.\u003c\/p\u003e\n\n\u003cp\u003eHow much of that 83 per cent a given Australian site actually banks depends almost entirely on where it is and what internal temperature the equipment owner will accept. Shelters are usually allowed to run warmer than a data hall, often in the high twenties or low thirties, and that generous setpoint is what makes Free Cooling productive here. A signalling hut in the Southern Highlands, an exchange building in Ballarat or a base station in the Central Tablelands will spend a large share of the year with ambient temperatures below the changeover point. A shelter in Darwin, Karratha or Mount Isa will spend far less, but even there the overnight hours in the dry season are worth capturing.\u003c\/p\u003e\n\n\u003cp\u003eThe trade off is that outside air enters the enclosure, so it has to be filtered and the filtration has to be monitored. The SplitAir uses a zigzag filter rated ISO 16890 ePM10 50 per cent, which removes half of particles up to ten micrometres, and it pairs that with a filter monitor and an airflow alarm so a blocked filter raises a fault rather than quietly strangling the airflow. On dusty inland sites, unsealed access roads and mine haul routes, filter interval is the single most important maintenance variable and it should be set from observed differential pressure rather than from a calendar.\u003c\/p\u003e\n\n\u003cp\u003eCondensation pressure control keeps the refrigerant circuit stable when the compressor does have to run at low ambient temperatures. Without it, head pressure collapses on a cold night and the expansion device loses control of superheat. This is the detail that separates equipment designed for continuous outdoor duty from equipment designed for an office wall.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eBackup operation when the main supply fails\u003c\/h2\u003e\n\n\u003cp\u003eMost container and shelter loads are already backed by a DC plant. The transmission equipment, the routers and the alarms all keep running from the 48 V battery string when mains power drops. The cooling usually does not, which is the weak link. A sealed shelter with a live heat load and no air movement heats up quickly, and the outage that the batteries were meant to ride through instead becomes a thermal shutdown.\u003c\/p\u003e\n\n\u003cp\u003eThe SplitAir addresses this directly. On failure of the main power supply the unit switches to backup operation and continues to provide Free Cooling and backup cooling from either 48 V DC or a 230 V, 50 Hz, single phase source. That means the same battery plant that keeps the radio alive also keeps air moving through the enclosure, and the site rides out a distribution fault, a storm outage or a generator changeover without an equipment room temperature alarm.\u003c\/p\u003e\n\n\u003cp\u003eFor operators working to a formal resilience obligation, and that increasingly includes utilities, transport authorities and any organisation caught by APRA CPS 230 operational risk expectations, this is a documented control rather than an assumption. It is worth writing the backup cooling mode into the site's outage procedure and testing it during commissioning, not discovering it during the first real event.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eRefrigerant charge and Australian regulation\u003c\/h2\u003e\n\n\u003cp\u003eSTULZ designs the SplitAir with a low refrigerant quantity, below ten tonnes of CO2 equivalent, and offers a hermetically sealed refrigerant circuit as standard with the EC compressor and as an option with the On\/Off compressor. In the European market that combination removes the requirement for an annual leak test under the EU F-gas Regulation.\u003c\/p\u003e\n\n\u003cp\u003eThat specific exemption does not apply in Australia, and it should not be quoted as though it does. The Australian regime is different. Synthetic greenhouse gas refrigerants are controlled under the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989 and its regulations, administered by the Department of Climate Change, Energy, the Environment and Water. Anyone handling refrigerant needs a Refrigerant Handling Licence issued by the Australian Refrigeration Council, commonly called an ARCtick licence, and any business acquiring, storing or disposing of refrigerant needs a Refrigerant Trading Authorisation. There is no blanket annual leak test mandated the way there is in Europe, but there is a legal obligation to prevent emissions, and site or contract level requirements often impose their own inspection schedule.\n\n\u003c\/p\u003e\n\n\u003cp\u003eWhat the low charge and sealed circuit do buy an Australian operator is a smaller compliance and leak check burden in practice. Less refrigerant on site means a lower quantity to account for, a smaller recovery volume at end of life, less exposure to refrigerant price movements as higher GWP gases are phased down under the HFC import quota, and a smaller consequence if a leak does occur. The refrigerant choice matters here too. R513A carries a GWP of 631 against 2,088 for R410A and 1,774 for R407C, so specifying the high temperature R513A variant on a hot inland site delivers a lower GWP charge as well as a wider operating envelope.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eControl, monitoring and remote access\u003c\/h2\u003e\n\n\u003cp\u003eThe SplitAir runs on the STULZ SEC.blue control system with inside and outside temperature sensors as standard. The outside sensor is not decoration. Free Cooling changeover is a comparison between the two, so an incorrectly sited or sun exposed outdoor sensor will cost real money by suppressing Free Cooling hours. Site it in shade, on the cool side of the shelter, away from the condensing unit discharge.\u003c\/p\u003e\n\n\u003cp\u003eMonitoring and remote access are provided over a web interface, which is the practical requirement for an unmanned asset. Temperature trends, alarm state, filter status and Free Cooling versus compressor hours can all be read without a site visit, and that history is what tells you whether a unit is genuinely healthy or is quietly running the compressor for hours it should not need to.

All electrical work must be carried out by a licensed electrician to AS\/NZS 3000, including the supply to the outdoor condensing unit, the isolation arrangements and the 48 V DC or 230 V backup feed. Any work on the refrigerant circuit, which includes brazing, evacuation, charging and the final commissioning leak test, must be carried out by an ARCtick licensed refrigeration technician under the Ozone Protection and Synthetic Greenhouse Gas Management Act and its regulations. Where the shelter forms part of a mechanical ventilation system, the hygiene and cleaning obligations of AS\/NZS 3666 also apply, and on a Direct Free Cooling unit that draws outside air into the enclosure they are worth taking seriously rather than treating as paperwork.\u003c\/p\u003e\n\n\u003cp\u003eTypical scope on a container or shelter job covers a heat load check against the actual equipment draw rather than the nameplate rating, indoor unit position and variant selection against the available wall depth, outdoor condensing unit siting with attention to discharge clearance and reflected heat off the container skin, line set routing and penetration sealing, condensate management, plug and play electrical termination, SEC.blue configuration including the Free Cooling changeover points, web interface and alarm integration, and a witnessed commissioning test that includes a deliberate mains failure to prove backup operation.\u003c\/p\u003e\n\n\u003cp\u003eIndicative pricing for cooling design and installation in the small band, which is where a single shelter or container project usually sits, runs from $8,000 to $15,000. Medium installations run $25,000 to $45,000 and large projects $45,000 to $60,000 plus. Multi site rollouts are quoted per site with mobilisation shared across the run, which is normally how a base station or signalling fleet programme is priced.\u003c\/p\u003e\n\n\u003cp\u003eOngoing maintenance for a shelter unit is short but non negotiable. Filter condition and differential pressure, coil cleanliness on both the indoor evaporator and the outdoor microchannel condenser, refrigerant charge and leak check, condensate drain and trap, damper operation and seal condition, backup mode function test, sensor calibration, and a review of the alarm and run hour history for the Free Cooling to compressor ratio. That last one is the cheapest diagnostic available. If Free Cooling hours drop year on year at the same site, something is wrong with a sensor, a damper or a filter long before it shows up as a failure.

It consists of an indoor evaporator unit and a separate outdoor condensing unit connected by a refrigerant line set, and it covers 5 kW to 16 kW of cooling capacity with airflow from 1,110 to 3,300 cubic metres per hour across two sizes and eight model codes.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eHow is the SplitAir different from other STULZ shelter cooling units?\u003c\/h3\u003e\n\u003cp\u003eThe SplitAir is the split system in the range. The refrigeration and heat rejection hardware sits in a separate outdoor condensing unit rather than in the same box as the evaporator, which is why the indoor unit is only 350 mm to 410 mm high and 885 mm to 1,370 mm deep. Other units in the STULZ shelter family are single unit designs, either mounted on the outside wall or standing inside the shelter. Choose the SplitAir when the container has no room for a full depth unit, or when the outdoor face of the shelter cannot carry one.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eHow much can Direct Free Cooling save on running costs?\u003c\/h3\u003e\n\u003cp\u003eSTULZ rates Direct Free Cooling on the SplitAir at up to 83 per cent savings on running costs compared with mechanical cooling alone. The actual saving at a given site depends on local climate, the internal temperature the equipment owner will accept and how many hours a year outside air is below the changeover point. Southern and inland Australian sites capture more of it than tropical coastal sites, but overnight hours are worth capturing everywhere.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eDoes the SplitAir keep cooling if the mains power fails?\u003c\/h3\u003e\n\u003cp\u003eYes. On failure of the main power supply the SplitAir switches to backup operation and continues to provide Free Cooling and backup cooling from either 48 V DC or a 230 V, 50 Hz, single phase source. Because most telecommunication and utility shelters already have a 48 V DC battery plant supporting the equipment load, the cooling can ride through the same outage the equipment does. The backup mode should be function tested at commissioning.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eDoes the low refrigerant charge exempt the unit from leak testing in Australia?\u003c\/h3\u003e\n\u003cp\u003eNo. The SplitAir holds less than ten tonnes of CO2 equivalent of refrigerant and offers a hermetically sealed circuit, which removes the annual leak test requirement under the EU F-gas Regulation, but that European exemption has no effect in Australia. Australian refrigerant handling sits under the Ozone Protection and Synthetic Greenhouse Gas Management Act, with ARCtick refrigerant handling licences and Refrigerant Trading Authorisations administered by the Australian Refrigeration Council. The low charge still reduces the practical compliance and leak check burden, and lowers recovery volumes and refrigerant cost exposure, but leak checking should be scheduled to your site and contract requirements.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eWhat ambient temperatures can the SplitAir operate in?\u003c\/h3\u003e\n\u003cp\u003eStandard outside air conditions are minus 20 degrees Celsius in winter to plus 50 degrees Celsius in summer. An optional winter kit extends operation down to minus 40 degrees Celsius, and optional high temperature operation with R513A refrigerant extends the upper limit to 55 degrees Celsius. That upper band is the relevant one for inland and northern Australian sites in the Pilbara, the Goldfields, North West Queensland and the Northern Territory.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eWhat does SNL80 mean in the SplitAir model code?\u003c\/h3\u003e\n\u003cp\u003eSNL80 is an EC compressor SplitAir with 8 kW nominal cooling capacity. The three letter prefix gives the compressor type, where SXL is an On\/Off compressor and SNL is an EC compressor, and the two character suffix gives nominal capacity, where 40 is 4 kW, 60 is 6 kW, 80 is 8 kW, A0 is 10 kW, A2 is 12 kW and A5 is 15 kW.

The refrigeration and heat rejection hardware sits in a separate outdoor condensing unit rather than in the same box as the evaporator, so the indoor unit is only 350 mm to 410 mm high and 885 mm to 1,370 mm deep.

On failure of the main power supply the SplitAir switches to backup operation and continues to provide Free Cooling and backup cooling from either 48 V DC or a 230 V, 50 Hz, single phase source. Because most telecommunication and utility shelters already have a 48 V DC battery plant supporting the equipment load, the cooling can ride through the same outage the equipment does. The backup mode should be function tested at commissioning.\"}},\n{\"@type\":\"Question\",\"name\":\"Does the low refrigerant charge exempt the unit from leak testing in Australia?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No. The SplitAir holds less than ten tonnes of CO2 equivalent of refrigerant and offers a hermetically sealed circuit, which removes the annual leak test requirement under the EU F-gas Regulation, but that European exemption has no effect in Australia. Australian refrigerant handling sits under the Ozone Protection and Synthetic Greenhouse Gas Management Act, with ARCtick refrigerant handling licences and Refrigerant Trading Authorisations administered by the Australian Refrigeration Council. The low charge still reduces the practical compliance and leak check burden and lowers recovery volumes, but leak checking should be scheduled to your site and contract requirements.\"}},\n{\"@type\":\"Question\",\"name\":\"What ambient temperatures can the SplitAir operate in?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Standard outside air conditions are minus 20 degrees Celsius in winter to plus 50 degrees Celsius in summer.

Indigi Power and Cooling supplies, installs, commissions and maintains WallAir units nationally from hubs in Brisbane, Sydney and Melbourne.\n  \u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cp\u003eShelter cooling is a different engineering problem to server room cooling, and the constraint that drives it is space. A typical mobile network base station cabin, rail signalling hut or utility RTU enclosure is a steel box a few metres on a side, and by the time the racks, the battery string, the rectifier and the cable trays are in, there is no wall left to hang anything on and no floor left to stand anything on. The STULZ WallAir answers that constraint directly. The entire unit mounts on the outside face of the container wall. Nothing but the air openings and the adapter frame passes through the skin, and the internal footprint is zero.\u003c\/p\u003e\n\n\u003cp\u003eThat decision cascades through the rest of the design. Because the unit lives outdoors it has to be weatherproof and it has to survive being touched by people who have no business touching it, which matters at unstaffed roadside and trackside sites. Because it lives outdoors, the compressor and fan noise stays outside the shelter rather than inside it, which makes technician visits more tolerable and keeps sound pressure at the equipment racks low. And because the outside air is already right there at the coil face, the WallAir is the natural home for Direct Free Cooling. STULZ rates the WallAir at up to 84 per cent savings on running costs through Direct Free Cooling, which is the highest Free Cooling saving figure quoted anywhere in the STULZ shelter and container cooling range.\u003c\/p\u003e\n\n\u003cp\u003eIndigi Power and Cooling is an Indigenous and Veteran owned critical power and cooling specialist, registered with Supply Nation and ICN Gateway.

The outside air circuit passes over the condenser and returns straight to atmosphere without ever entering the shelter. The internal air circuit draws warm air out of the container, passes it over the evaporator or the Free Cooling path, and returns it as a cool displacement stream low in the shelter. Only the two openings and the mounting frame penetrate the container wall.\u003c\/p\u003e\n\n\u003cp\u003eFour practical consequences follow, and they are the reasons an engineer picks WallAir over an internally mounted unit.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eInternal space.\u003c\/strong\u003e Nothing is consumed. On a shelter that has already been extended twice and now has racks on three walls, this is often the deciding factor. It also means the cooling can be upgraded later without a rack move, because the capacity increase happens on the outside face.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eNoise inside the shelter.\u003c\/strong\u003e Compressor and condenser fan noise is generated outdoors. Inside the container you hear the displacement air stream and little else. On sites where a technician may spend several hours in a small steel box, that is a genuine work health and safety improvement, not a marketing point.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWeather and UV exposure.\u003c\/strong\u003e The unit is rated for continuous outdoor duty from minus 20 to plus 50 degrees Celsius as standard. In Australia the design questions are corrosion in coastal and near coastal locations, wind loading on cyclone exposed sites in northern Queensland, the Northern Territory and the Pilbara, and ultraviolet degradation of any exposed sealing or cable gland. All three are answerable at specification stage with the correct coating, fixing detail and cable entry, and all three should be raised before the order rather than after the first summer.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eVandalism and interference.\u003c\/strong\u003e An externally mounted unit is reachable, so unattended roadside, trackside and remote sites usually need a physical strategy around it. In practice that means siting the unit on the least accessible wall, adding a guard or cage where the site risk assessment calls for it, and using the SEC.blue remote monitoring to raise an alarm on airflow loss or filter blockage rather than waiting for a temperature alarm that arrives after the equipment has already throttled.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eRetrofit without changing the container cutout\u003c\/h2\u003e\n\n\u003cp\u003eThis is the commercial argument that matters most to Australian telco, rail and utility operators, because most of them are not building new shelters. They are maintaining a fleet of them, and the cooling units in that fleet are reaching the end of their service life at roughly the same time.\u003c\/p\u003e\n\n\u003cp\u003eSTULZ states that the WallAir can be retrofitted without changes to the container cutout, using a universal adapter frame for fast and easy replacement by a new WallAir model. That single sentence removes the most expensive and most uncertain part of a replacement job. Without an adapter frame, swapping a wall mounted unit for a different model normally means cutting, patching or re-framing the aperture in the container skin. That is hot work on a live site, it needs the shelter opened up, it needs a weatherproof detail rebuilt and re-sealed, and it usually needs a trade on site that is not the refrigeration technician.\u003c\/p\u003e\n\n\u003cp\u003eWith the adapter frame, the job reduces to isolate, disconnect, unbolt, lift off, fit frame, lift on, bolt up, reconnect, commission. The plug and play electrical connector helps here too, because the field wiring termination is a connector rather than a set of loose cores into a terminal rail. On a fleet replacement programme run across dozens of sites, the difference between a job that needs sheet metal work and one that does not is measured in whole days per site, and it changes the mobilisation plan entirely.\u003c\/p\u003e\n\n\u003cp\u003eThree things are worth confirming before you commit to a fleet retrofit. First, the existing aperture dimensions and the structural condition of the wall around it, because an adapter frame solves geometry, not corrosion. Second, the available supply arrangement, since older shelters sometimes have a supply sized for a smaller or less efficient unit. Third, the intended backup arrangement, because the WallAir supports backup operation on 48 V DC or 230 V single phase and the choice affects how it integrates with the existing DC plant. Indigi surveys these three points as part of quoting a retrofit programme.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eDirect Free Cooling and the 84 per cent figure\u003c\/h2\u003e\n\n\u003cp\u003eDirect Free Cooling means filtered outside air is used to cool the shelter directly, with the compressor off. It works in a shelter far more often than it works in a data hall, for a simple reason: the internal setpoint in a comms shelter is typically much higher than the 18 to 27 degrees Celsius server inlet band described in ASHRAE TC 9.9 for IT equipment. Telecommunications and utility equipment is frequently specified to run comfortably in the high twenties or low thirties, so the outside air only has to be a few degrees below that to do useful work. Across most of Australia, a large fraction of the year qualifies.\u003c\/p\u003e\n\n\u003cp\u003eThe WallAir moves through the operating modes automatically. In Free Cooling the outside air damper opens and the compressor stays off. In Mixed mode the compressor runs at part load to top up what the outside air cannot deliver. In full mechanical cooling the damper closes and the unit runs conventionally. STULZ rates the resulting saving at up to 84 per cent on running costs, which is the highest Free Cooling figure quoted in the STULZ shelter range and reflects how much of the year a well sited unit can avoid running its compressor at all.\u003c\/p\u003e\n\n\u003cp\u003eTwo design points determine whether you get near that number in practice. The first is filtration, because Direct Free Cooling brings outside air into the shelter. The WallAir uses a zigzag filter to ISO 16890 ePM10 50 per cent with a filter monitor and airflow alarm, which is appropriate for a shelter but does mean filter changes are a scheduled maintenance item rather than an afterthought, particularly on unsealed access roads, on mine sites and during bushfire smoke events. The second is the internal setpoint you are willing to hold. Every degree you relax the internal setpoint upward, within the equipment manufacturer's stated limits, adds Free Cooling hours to the year. That is a conversation between the network owner and the equipment vendor, and it is worth having before the cooling is specified.\u003c\/p\u003e\n\n\u003cp\u003eWhere outside air quality rules out a direct arrangement, or where the shelter has a tighter internal environment requirement, the correct answer is usually a different unit in the same STULZ range rather than a compromised WallAir selection. Indigi will say so at selection stage.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eControl, monitoring and remote sites\u003c\/h2\u003e\n\n\u003cdiv style=\"display:grid;grid-template-columns:repeat(auto-fit,minmax(240px,1fr));gap:18px;margin-bottom:24px;\"\u003e\n  \u003cdiv style=\"border:1px solid #e3e3e3;border-radius:8px;padding:16px;background-color:#fafafa;text-align:center;\"\u003e\n    \n    \u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:0 0 6px 0;\"\u003eSEC.blue control\u003c\/h3\u003e\n    \u003cp style=\"font-size:15px;color:#555;margin:0;text-align:left;\"\u003eThe controller reads both inside and outside temperature, which is what makes the Free Cooling changeover decision possible.

Compressor soft start keeps start-up current low, which is relevant where the site is fed from a small transformer, a long rural feeder or a generator. And backup operation on 48 V DC or 230 V single phase means the cooling can be tied into the same DC plant that already backs the radio or SCADA equipment, so a mains outage does not immediately become a thermal event. Condensation pressure control keeps the refrigerant circuit stable when the outside temperature drops, which is what allows the unit to be used at the cold end of its range rather than only in summer conditions.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eRefrigerant charge and Australian compliance\u003c\/h2\u003e\n\n\u003cp\u003eThe WallAir carries a low refrigerant charge, held below ten tonnes of CO2 equivalent, and the circuit is hermetically sealed as standard on EC compressor models and available as an option on On\/Off models. The STULZ brochure notes that this removes the requirement for the annual leak test under the European F-gas regulation.\u003c\/p\u003e\n\n\u003cp\u003eThat exemption is a European rule and it does not transfer to Australia. The applicable regime here is the Ozone Protection and Synthetic Greenhouse Gas Management Act and its regulations, administered through ARCtick licensing. Anyone handling refrigerant on a WallAir in Australia needs an ARCtick refrigerant handling licence, and the business doing the work needs a refrigerant trading authorisation to acquire, store or dispose of refrigerant. Do not assume the European leak test exemption applies to your Australian sites, because the two schemes are structured differently.\u003c\/p\u003e\n\n\u003cp\u003eWhat the low charge and the sealed circuit do give you in Australia is a smaller compliance and leak-check burden in practical terms. There is less refrigerant to account for, less to recover at end of life, fewer field joints to inspect on a hermetically sealed circuit, and a smaller exposure if a leak does occur. On a fleet of dozens or hundreds of shelters that is a meaningful reduction in both cost and reporting effort, even though the licensing obligations themselves are unchanged.

All electrical work must be carried out by a licensed electrician to AS\/NZS 3000, including the supply to the unit, the plug and play connector termination and any interface to the site DC plant for backup operation. All work on the refrigerant circuit requires an ARCtick licensed refrigeration technician under the Ozone Protection and Synthetic Greenhouse Gas Management Regulations. Where the WallAir forms part of a mechanical ventilation arrangement, and Direct Free Cooling means it often does, the hygiene obligations in AS\/NZS 3666 apply to the outside air path, the filters and the condensate arrangement. Indigi carries out all three streams in house rather than subcontracting the critical path.\u003c\/p\u003e\n\n\u003cp\u003eA typical installation scope covers heat load verification against the actual equipment draw rather than the nameplate, confirmation of the wall cutout and structural fixing detail, the adapter frame where the job is a retrofit, rigging and mounting, refrigerant charge check and leak test, electrical connection and isolation, SEC.blue configuration including the Free Cooling changeover strategy and alarm thresholds, remote access setup and testing, and witness commissioning with a documented handover. Indicative pricing for server room and shelter cooling design and installation runs from $8,000 to $15,000 for small rooms and single shelter jobs, $25,000 to $45,000 for medium installations and $45,000 to $60,000 plus for large projects. On a multi site rollout the per site figure typically falls once the design is settled and the mobilisation is planned in blocks, so ask us for a programme price rather than a single site price.\u003c\/p\u003e\n\n\u003cp\u003eOnce running, a WallAir needs a maintenance regime built around its outdoor location. Filters are the single most common cause of gradual capacity loss and the filter monitor will flag them, but the schedule should also cover condenser coil cleanliness on the microchannel coil, corrosion inspection at the mounting frame and fixings, seal and gasket condition at the wall penetration, damper operation for the Free Cooling changeover, refrigerant charge, compressor and fan health, condensate management, and a review of controller alarm history.

The entire unit mounts on the outside face of the container wall, with only the air openings and the mounting frame passing through the skin, so it consumes zero internal floor or wall space. It covers 4 kW to 16 kW of cooling capacity in two cabinet sizes with displacement air conduction.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eHow much can Direct Free Cooling save on a STULZ WallAir?\u003c\/h3\u003e\n\u003cp\u003eSTULZ rates Direct Free Cooling on the WallAir at up to 84 per cent savings on running costs, which is the highest Free Cooling saving figure in the STULZ shelter and container cooling range. The actual saving depends on site location, the internal setpoint you are willing to hold and the outside air quality at the site. Shelters achieve more Free Cooling hours than data halls because the permitted internal temperature is usually well above the ASHRAE TC 9.9 recommended 18 to 27 degrees Celsius server inlet band.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eWhat cooling capacities and sizes does the WallAir cover?\u003c\/h3\u003e\n\u003cp\u003eThe WallAir range covers 4 kW to 16 kW across ten models in two cabinet sizes. On\/Off compressor models run from WXD40 at 4.6 kW to WXDA6 at 15.5 kW, and EC compressor models are WND80 at 7.7 kW, WNDA4 at 13.2 kW and WNDA6 at 16.0 kW. Size 1 cabinets are 879 mm wide by 2,137 mm high by 565 mm deep. Size 2 cabinets are 992 mm wide by 2,192 mm high by 730 mm deep. Capacities are quoted at 30 degrees Celsius inside, 30 per cent relative humidity and 35 degrees Celsius outside.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eCan a WallAir be retrofitted into an existing container cutout?\u003c\/h3\u003e\n\u003cp\u003eYes. STULZ states that the WallAir can be retrofitted without changes to the container cutout, using a universal adapter frame for fast and easy replacement by a new WallAir model. That removes sheet metal work from the replacement job, which is the expensive and uncertain part of a fleet upgrade. Before committing to a programme, confirm the existing aperture dimensions and the structural condition of the wall around it, the available electrical supply, and how the 48 V DC or 230 V single phase backup arrangement will tie into the existing site plant.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eWhat outside air temperatures can a WallAir handle in Australia?\u003c\/h3\u003e\n\u003cp\u003eStandard outside air conditions are minus 20 degrees Celsius in winter to plus 50 degrees Celsius in summer. An optional winter kit extends the lower limit to minus 40 degrees Celsius, and optional high temperature operation extends the upper limit to 55 degrees Celsius using R513A refrigerant at GWP 631. Condensation pressure control keeps the refrigerant circuit stable at the cold end of the range. For coastal, cyclone exposed and high ultraviolet Australian sites, corrosion protection, wind loading on the fixing detail and cable gland selection should be specified at order stage.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eDoes the low refrigerant charge remove the annual leak test in Australia?\u003c\/h3\u003e\n\u003cp\u003eNo. The STULZ brochure notes that the low charge and hermetically sealed circuit remove the annual leak test requirement under the European F-gas regulation, but that is a European rule and it does not transfer to Australia. The applicable Australian regime is the Ozone Protection and Synthetic Greenhouse Gas Management Act, administered through ARCtick licensing, and refrigerant work still requires an ARCtick licensed technician and a refrigerant trading authorisation. What the low charge, held below ten tonnes of CO2 equivalent, does deliver here is a smaller practical compliance and leak-check burden, with less refrigerant to account for, fewer field joints to inspect and less to recover at end of life.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:24px 0 8px 0;\"\u003eWho installs and services STULZ WallAir units in Australia?\u003c\/h3\u003e\n\u003cp\u003eIndigi Power and Cooling supplies, installs, commissions and maintains STULZ shelter and container cooling equipment across Australia from hubs in Brisbane, Sydney and Melbourne.

The applicable Australian regime is the Ozone Protection and Synthetic Greenhouse Gas Management Act, administered through ARCtick licensing, and refrigerant work still requires an ARCtick licensed technician and a refrigerant trading authorisation.

STULZ rates Mixed and Free Cooling operation at up to 83 per cent savings on energy costs. Indigi Power and Cooling supplies, installs, commissions and maintains STULZ TelAir units nationally from hubs in Brisbane, Sydney and Melbourne.\n  \u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cp\u003eTelecommunications shelters, equipment rooms and modular containers are a different cooling problem to a data hall. The heat load is small in absolute terms, usually somewhere between 3 kW and 15 kW, but it is constant, the room is unoccupied for most of the year, and the consequence of losing cooling is a base station, an exchange or a signalling system dropping out. The STULZ TelAir is built specifically for that duty. It is a floor standing, indoor installed unit covering 4 kW to 16 kW in two cabinet sizes, with a Free Cooling capability that lets it run for long periods without engaging the compressor at all.\u003c\/p\u003e\n\n\u003cp\u003eThe distinguishing feature of the TelAir within the STULZ shelter cooling range is that it goes inside the box. STULZ states in the shelter cooling brochure that TelAir units are designed for installation in telecommunications containers, equipment rooms and server rooms, and that because they are installed indoors, noise is kept to a minimum and the units are protected against environmental influences and vandalism. For Australian operators that matters in three specific situations: sites where an external unit cannot be mounted at all, such as heritage listed buildings, leased tenancies and cyclone rated structures in northern Australia; unattended remote sites where anything reachable from the ground eventually gets interfered with; and sites where the acoustic assessment measures noise at the boundary rather than inside the room.\u003c\/p\u003e\n\n\u003cp\u003eThe TelAir is also the model in the range with the widest choice of air conduction. Upflow, Downflow and Displacement are all available, and the Displacement variant with adjustable fins lets the airflow be directed horizontally or vertically entirely as required to suit the equipment layout. That flexibility is what usually decides a retrofit, because in an existing shelter you rarely get to choose where the racks sit.\u003c\/p\u003e\n\n\u003cp\u003eIndigi Power and Cooling is an Indigenous and Veteran owned critical power and cooling specialist, registered with Supply Nation and ICN Gateway.

An existing exchange room or base station shelter already has its racks, its cable trays and its DC plant in fixed positions, often installed decades apart by different contractors. Being able to aim the discharge at the equipment after the unit is in place, rather than accepting whatever the geometry gives you, is what keeps rack inlet temperatures inside the ASHRAE TC 9.9 recommended envelope of 18 to 27 degrees Celsius without adding ductwork.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eFree Cooling, Mixed Cooling and what it saves in Australia\u003c\/h2\u003e\n\n\u003cp\u003eA TelAir does not have to run its compressor to cool a shelter. When the outside air is cooler than the room, the unit can reject heat without mechanical cooling, and STULZ rates the resulting operating cost reduction at up to 83 per cent savings on energy costs across the Mixed and Free Cooling modes. The brochure notes that TelAir units are especially efficient in Free Cooling mode, achieving maximum EER values because of their high airflow in Free Cooling and Mixed modes. Airflow is the lever: moving more air at low fan power displaces more compressor hours.\u003c\/p\u003e\n\n\u003cp\u003eOperation moves between three states. In Free Cooling the compressor is off and the cooling is done by outside air conditions alone. In Mixed Cooling the compressor runs at part load to top up the shortfall, which is where a large share of the annual hours actually sit in most Australian locations. In mechanical cooling the unit runs conventionally, which is what happens through a Brisbane or Darwin summer afternoon.\u003c\/p\u003e\n\n\u003cp\u003eHow much of the year lands in each mode depends entirely on where the shelter is. A signalling hut on the Victorian regional network, a Canberra exchange, a Tasmanian repeater site or an inland New South Wales base station will spend a large part of the year in Free Cooling or Mixed Cooling. A Pilbara or Top End site will not, and there the honest argument for the TelAir is different: reliability, the minus 20 to plus 50 degrees Celsius standard operating envelope, the optional high temperature package to 55 degrees Celsius using R513A, and condensation pressure control that keeps the refrigerant circuit stable when the ambient swings hard between night and day.\u003c\/p\u003e\n\n\u003cp\u003eTwo options matter at the extremes of the Australian range. The optional winter kit extends operation down to minus 40 degrees Celsius, which is well beyond anything on the mainland but relevant to alpine and sub-antarctic work. The optional high temperature operation to 55 degrees Celsius with R513A is the one that comes up repeatedly on mine sites, remote telecommunications repeaters and unshaded rooftop plant rooms in the north.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eRefrigerant charge and Australian compliance\u003c\/h2\u003e\n\n\u003cp\u003eThe TelAir carries a low refrigerant charge, below ten tonnes of CO2 equivalent, in a hermetically sealed refrigerant circuit. The sealed circuit is standard on EC compressor models and optional on On\/Off compressor models. STULZ points out in the brochure that this removes the requirement for the annual leak test under the European F-gas Regulation. That exemption is a European provision and it does not carry across to Australia, so it should not be relied on when writing an Australian maintenance specification.\u003c\/p\u003e\n\n\u003cp\u003eIn Australia the governing regime is the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989 and its regulations. Under that framework, anyone handling fluorocarbon refrigerant needs an ARCtick refrigerant handling licence issued by the Australian Refrigeration Council, and any business that acquires, stores or disposes of refrigerant needs a Refrigerant Trading Authorisation. Those obligations apply regardless of charge size, and they apply to a 3 kg shelter unit exactly as they apply to a data hall chiller.\u003c\/p\u003e\n\n\u003cp\u003eWhat the low charge does change is the practical cost and risk. A smaller charge means less refrigerant to lose in a leak event, a smaller recovery and recharge job when a component is replaced, a lower embodied carbon exposure if your organisation reports on it, and a lighter leak checking burden in a maintenance regime that is written on a risk basis rather than a fixed schedule. On a national base station fleet with hundreds of shelters, that difference is material across the asset life. The refrigerant options themselves also matter to a long term specification: R410A at GWP 2,088 with the EC compressor, R407C at GWP 1,774 with the On\/Off compressor, and R513A at GWP 631 where high temperature operation is specified.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eControl, monitoring and unattended site operation\u003c\/h2\u003e\n\n\u003cdiv style=\"display:grid;grid-template-columns:repeat(auto-fit,minmax(260px,1fr));gap:18px;margin-bottom:24px;\"\u003e\n  \u003cdiv style=\"border:1px solid #e3e3e3;border-radius:8px;padding:16px;background-color:#fafafa;text-align:center;\"\u003e\n    \n    \u003ch3 style=\"font-size:19px;font-weight:700;color:#111111;margin:0 0 6px 0;\"\u003eSEC.blue control\u003c\/h3\u003e\n    \u003cp style=\"font-size:15px;color:#555;margin:0;text-align:left;\"\u003eThe SEC.blue controller manages the changeover between Free Cooling, Mixed Cooling and mechanical cooling using inside and outside temperature sensors, and drives the filter monitor and airflow alarm.

The TelAir can be arranged to run on 48 V DC or on 230 V \/ 50 Hz single phase, which lets cooling ride through a mains outage on the same DC plant that keeps the radio equipment alive. Compressor soft start keeps start-up currents low, which is exactly what you want when the unit restarts onto a generator or an inverter rather than onto the grid. Plug and play electrical wiring with a connector shortens the licensed electrical work at each site, which is worth real money when the same install is being repeated across a fleet.\u003c\/p\u003e\n\n\u003cp\u003eFiltration is ISO 16890 class ePM10 50 per cent using a zigzag filter element, monitored so that a blocked filter raises an alarm rather than quietly eroding capacity. Because a shelter unit runs unattended between visits, and because Australian sites bring red dust, pollen, coastal salt and bushfire smoke, filter condition is the single most common cause of a gradual loss of cooling capacity on this class of equipment.

All electrical work must be carried out by a licensed electrician to AS\/NZS 3000, covering the supply to the unit, termination of the plug and play connector, and any interface to the site DC plant where 48 V backup operation is used. All work on the refrigerant circuit requires an ARCtick licensed refrigeration technician under the Ozone Protection and Synthetic Greenhouse Gas Management Act and its regulations, and the business carrying out the work needs a Refrigerant Trading Authorisation. Where the unit forms part of a mechanical ventilation arrangement, the hygiene obligations in AS\/NZS 3666 apply to the air path, the filters and the condensate arrangement. Indigi carries out all of this in house rather than subcontracting the critical path.\u003c\/p\u003e\n\n\u003cp\u003eA typical installation scope covers heat load verification against the actual equipment draw rather than the nameplate, confirmation that the chosen air conduction direction suits the existing rack and cable tray layout, floor loading and access route checks for a 2,050 mm tall cabinet, positioning and fixing, condenser air path and any wall penetrations, refrigerant charge check and leak test, electrical connection and isolation, SEC.blue configuration including Free Cooling changeover strategy and alarm thresholds, remote access and Ethernet setup where specified, and witness commissioning with a documented handover. Indicative pricing for server room and shelter cooling design and installation runs from $8,000 to $15,000 for small rooms and single shelter jobs, $25,000 to $45,000 for medium installations and $45,000 to $60,000 plus for large projects. On a multi site rollout the per site figure typically falls once the design is settled and mobilisations are planned in blocks, so ask us for a programme price rather than a single site price.\u003c\/p\u003e\n\n\u003cp\u003eOnce running, a TelAir needs a maintenance regime built around unattended continuous duty. Filters come first, and the filter monitor will flag them, but the schedule should also cover microchannel condenser coil cleanliness, condensate management, refrigerant charge and leak inspection, compressor and fan health, damper and fin operation where the Displacement with fins variant is fitted, verification of the Free Cooling changeover, backup operation testing on the 48 V DC or 230 V supply, and a review of controller alarm history since the last visit.

Unlike the outdoor mounted models in the STULZ shelter range, the TelAir is installed indoors, inside the telecommunications container, equipment room or server room. STULZ states that because the units are installed indoors, noise is kept to a minimum and the units are protected against environmental influences and vandalism.\"}},\n{\"@type\":\"Question\",\"name\":\"What cooling capacity does the STULZ TelAir cover?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The range covers 4 kW to 16 kW in two sizes.

Upflow, Downflow, Displacement, and Displacement with adjustable fins. In the Displacement model with fins the airflow can be directed horizontally or vertically entirely as required to suit the server layout. This is the widest choice of air conduction in the STULZ shelter cooling range, and it is the main technical reason to choose a TelAir over an outdoor wall mounted unit in a retrofit where the rack layout is already fixed.\"}},\n{\"@type\":\"Question\",\"name\":\"How much can Free Cooling save on a STULZ TelAir?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"STULZ rates Mixed and Free Cooling operation at up to 83 per cent savings on energy costs, and notes that TelAir units are especially efficient in Free Cooling mode, achieving maximum EER values because of their high airflow in Free Cooling and Mixed modes. Actual savings depend entirely on site location. Cooler sites in Victoria, Tasmania, the ACT and inland New South Wales capture far more Free Cooling hours than Darwin, Cairns or the Pilbara.\"}},\n{\"@type\":\"Question\",\"name\":\"Which refrigerants does the STULZ TelAir use and what does Australian regulation require?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"R410A at GWP 2,088 with the EC compressor, R407C at GWP 1,774 with the On\/Off compressor, and R513A at GWP 631 where high temperature operation to 55 degrees Celsius is specified. Charge sizes sit below ten tonnes of CO2 equivalent in a hermetically sealed circuit, standard with the EC compressor and optional with the On\/Off compressor. In Australia the applicable regime is the Ozone Protection and Synthetic Greenhouse Gas Management Act, which requires ARCtick licensing for refrigerant handling and a Refrigerant Trading Authorisation for the business. The European F-gas exemption from annual leak testing does not apply here, although a low charge does reduce the practical compliance and leak checking burden.\"}},\n{\"@type\":\"Question\",\"name\":\"Should I specify a STULZ TelAir or a STULZ WallAir?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Choose the TelAir where there is internal floor space to give up and the site benefits from having the plant protected: high vandalism or theft risk, severe coastal or high UV exposure, restrictions on external mounting such as heritage listed or leased premises, cyclone rated structures, or an awkward equipment layout that needs directed airflow. Choose the WallAir where internal space is the binding constraint or an existing wall cutout is being reused.
