Air cooled chiller 26-48 kw

R410A refrigerant gas Chillers and heat pumps are designed to meet the cooling needs of small and medium-sized residential and office buildings. All units have class A energy efficiency and are equipped with inverter control on the Scroll compressor to provide higher efficiency at part loads (SEER/IPLV/SCOP). The following versions of these units are available.

CHA/IK/A - Cooling only
CHA/IK/A/MC - Cooling only with microchannel condensing coil
CHA/IK/A/WP - Both heating and cooling

Chillers with microchannel condensing coil provide high efficiency (high EER) due to better heat exchange than traditional coil chillers.
The units comply with the ErP Regulation. Upon request, the devices can be equipped with R452B or R454B refrigerant gas.
