CyberAir 2 - Innovation For Maximum Energy-efficiency

The CyberAir 2 precision air-conditioning system with DFC conditions the air in large computer and equipment rooms with a heat load of over 20 kW up to 60 % more economically than conventional compressor cooling systems.

CyberAir 2 is the world’s first precision air-conditioning system that considers heat load in computer rooms and seasonally varying ambient temperatures. It automatically selects the optimal operation mode for each case. In cool weather, the optional DFC automatic air-conditioning technology makes use of thrifty dynamic free cooling with outside air. Energy-intensive compressor cooling (DX) is only switched on when absolutely necessary. For this purpose, all units are equipped with speed-controlled EC fans and electronic expansion valves.

In addition to the DFC version described above, STULZ also offers the CyberAir 2 series in the versions A, G, GE, ACW, GCW, CW and CW2. CyberAir 2 units are available in six sizes. They require floor space 1000 mm to 2900 mm wide and only 890 mm deep. And the planner has a choice of three coolants - R407C, R410A or R134a.
