Indigi Power and Cooling supplies, installs, commissions and maintains CyberAir 3PRO DX units nationally from hubs in Brisbane, Sydney and Melbourne.\n  \u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003ePrecision cooling is not the same as comfort air conditioning. 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. We handle CyberAir 3PRO DX supply, installation, commissioning and ongoing maintenance, and we also service the installed base of STULZ equipment already running in Australian facilities.\u003c\/p\u003e\n\u003ch2 style=\"font-size:22px;font-weight:800;color:#111111;margin:34px 0 16px 0;\"\u003eSee the CyberAir 3PRO in operation\u003c\/h2\u003e\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\/f2fKLO5roh0\" title=\"STULZ CyberAir 3PRO precision air conditioning unit overview\" loading=\"lazy\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" 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 CyberAir 3PRO product overview, 3 minutes 29 seconds.

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.

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.
