Liquid chiller CLINT CHA/IK/A 302 P

CHA/IK/A 302 P

Liquid chiller unit with energy efficiency class A, with axial fans, inverter scroll compressors, microchannel condenser and plate heat exchanger.

The CHA/IK/A series of chilled water units with energy efficiency class A, operating on R410A refrigerant, has been designed for applications in medium-sized office and industrial air conditioning systems.

Used in cooperation with fan coil units, they provide air conditioning of rooms or remove heat generated as part of the industrial process. The possibility of equipping the units with the RS 485 ModBus interface allows to achieve a high and satisfactory level of comfort. The units are equipped with axial fans, inverter scroll compressors, condensers with microchannel coil and plate heat exchangers, also in super quiet version. The microchannel coil ensures high efficiency (high EER) and better heat exchange compared to traditional condensers. Higher efficiency at partial load (ESEER/IPLV) is guaranteed by inverter-controlled Scroll compressors. In addition, the inverter-controlled circulation pump and fans (Inverter EC) further increase efficiency. A wide range of accessories, factory-fitted or supplied separately, increases the versatility and functionality of this series of devices.
