The ventilating section has been dimensioned to allow excellent heat exchange with reduced noise levels. Moreover, the electronic expansion valve allows precise, quick and punctual regulation at different load conditions.

Energy saving, reliable and versatile chillers

The Free Cooling with no-glycol option can supply partial or total cooling capacity – for use where ethylene glycol or other antifreeze solutions is not permitted in the system. The Free Cooling no-glycol unit consists of an intermediate hydraulic circuit with ethylene glycol, which is directly coupled with a heat exchanger where the water circulates without an antifreeze solution.
