Our new CyberAir air-conditioning unit with Direct Free Cooling for medium-sized to large data centres slims down on demand, saving even more energy! This works thanks to a special heat exchanger – a new design that we have developed and patented for the CyberAir AMD units.

In “Direct Free Cooling” mode, the heat exchanger moves to the side, enabling the conditioned ambient air to fl ow unimpeded and without losses into the cavity under the raised fl oor. This technique brings about a further improvement in energy effi ciency.

When Direct Free Cooling is used, the heat exchanger automatically folds away to the side. The filtered ambient air can then flow into the void under the raised floor unhampered and without further losses. This brings a further improvement in efficiency.

In “DX” or “CW” mode, the heat exchanger automatically moves back into position, and air-conditioning continues reliably in compressor mode or with chilled water from the outdoor chiller.
