The liquid Chillers and Heat Pumps of the CHA 702-V÷5602-V series are designed to satisfy the needs of large-sized service sector or industrial areas.
They are used, in combination with Fan Coil units, for the air conditioning of the rooms or to remove the heat developed during industrial processes. Equipped with axial fans, Screw compressors and shell and tube exchanger, even in the super silent version, these units can be completed by a hydraulic circuit with tank, with pump, or with tank and pump. The use of large condensing coils and fans with high unit efficiency, as well as the optimization of the hydraulic and cooling circuit and the use of latest generation screw compressors, combined with a suitable sizing of the user system, allows to obtain high efficiency during operation with remarkably reduced energy consumption.
A wide range of accessories, factory fitted or supplied separately, complete the outstanding versatility and functionality of the series.
Are available as option the new EC Inverter fans with high available static pressure and efficiency.

Units not ErP compliant. Built in accordance with CE standards.
