Water source heat pump CARRIER®62W

commercialoutdoormonobloc

The 62W Series dedicated outdoor air unit utilizes a variable speed scroll compressor on the lead circuit and efficient scroll compressors on the lag circuit, that have been optimally designed for use with Puron Advance™ refrigerant (R-454B). Operating efficiency of the units may be increased by adding the optional energy recovery system. The 62W Series units are designed to meet customer requirements for ventilation air applications. All 62W units include a factory installed and programmed DDC controller, capable of standalone operation or integration into a building automation system via BACnet.
