CHAXT/K/AF 182-P÷604-P
High efficiency air cooled liquid Chillers and Heat Pumps with axial fans, Scroll compressors and plate exchanger
The liquid Chillers and Heat Pumps of the CHAXT/K/AF 182-P÷604-P series, with R410A refrigerant, are designed for medium-sized service sector or industrial ambients.
Equipped with axial fans, Scroll compressors and plate exchanger, these units can be completed by a hydraulic circuit with tank, with pump, or with tank and pump. A wide range of accessories, factory fitted or supplied separately, complete the outstanding versatility and functionality of the series.
They are used, combined with Fan Coil units, for the air conditioning or heating of the rooms or to remove the heat developed during industrial processes. They can be supplied with Modbus RTU protocol through RS485 serial interface.
