The liquid Chillers and Heat Pumps of the CHA/IK/A 91÷151 series, with R410A refrigerant, are designed to satisfy the needs of small and medium domestic and service sector environments.
With a peraluman structure corrosion-resistant over time, these units can be combined with Fan Coil units or with intermediate heat exchangers for process cooling applications.
All units feature A CLASS energy efficiency and are equipped with Inverter control on Scroll compressor for a better efficiency at partial loads (SEER/IPLV/SCOP). The Microchannel condensing coil, available on the dedicated version, ensures an even higher efficiency (high EER), having a better heat exchange than traditional coils.
The units are compliant to the ErP Regulation.
On request, units can be supplied with R452B or R454B refrigerant.
