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.

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.

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.
