Free-Air cooling can drastically reduce the energy consumption of your air conditioning system.

Wherever office space or comms rooms already have conventional air conditioning, the addition of a Free-Air cooling unit makes a huge difference to operating costs.

The system module takes over the control of the existing comfort A/C units and adds economical direct free cooling to the energy-intensive compressor cooling function. Whenever the ambient temperature allows, Free-Air is activated and the comfort A/C units are switched off.
