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.

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.\"}},\n{\"@type\":\"Question\",\"name\":\"How is the SplitAir different from other STULZ shelter cooling units?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The 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, so 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.\"}},\n{\"@type\":\"Question\",\"name\":\"How much can Direct Free Cooling save on running costs?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"STULZ 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 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.\"}},\n{\"@type\":\"Question\",\"name\":\"Does the SplitAir keep cooling if the mains power fails?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes. 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. 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.\"}},\n{\"@type\":\"Question\",\"name\":\"What does SNL80 mean in the SplitAir model code?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"SNL80 is an EC compressor SplitAir with 8 kW nominal cooling capacity.
