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.

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. Where a rollout covers many cabinets we standardise the install detail once and repeat it, which is what makes the per site cost sensible.\u003c\/p\u003e\n\n\u003cp\u003ePricing for cabinet cooling is quoted per site or per rollout rather than from a price band, because the cost is driven by the number of enclosures, their geographic spread, traffic management requirements and whether the electrical supply already exists at the cabinet. Send us the site list and we will price it properly. Our published design and install bands are for server room cooling projects and are not a sensible guide for a 1 to 2 kW street cabinet unit.\u003c\/p\u003e\n\n\u003cp\u003eFor ongoing support, see our \u003ca href=\"\/pages\/crac-unit-maintenance-services\" style=\"color:#d9590c;\"\u003eCRAC unit maintenance services\u003c\/a\u003e and \u003ca href=\"\/pages\/dx-crac-servicing-brisbane-sydney-melbourne\" style=\"color:#d9590c;\"\u003eDX servicing\u003c\/a\u003e pages.

STULZ states that units can be serviced and replaced by the operator's own personnel with no refrigeration engineers required, because the unit is a sealed Plug and Play module that is exchanged as a whole rather than opened, so the refrigerant circuit is never broken into. Any work that does involve the refrigerant circuit, including recovery, charging, leak repair and degassing a retired module, still requires an ARCtick licensed technician under the Ozone Protection and Synthetic Greenhouse Gas Management Regulations.
