Carrier® Dedicated Outdoor Air Unit.

Carrier® Dedicated Outdoor Air Unit

With Puron® Refrigerant (R-410A)

3 to 55 Nominal Tons

The 62X Series dedicated outdoor air unit utilizes variable capacity compressors on the lead circuit and efficient scroll compressors on the lag circuit, that have been optimally designed for use with Puron® refrigerant (R410A). Operating efficiency of the units may be increased by adding the optional energy recovery system. The 62X Series units are designed to meet customer requirements for ventilation air applications. All 62X units include a factory installed and programmed BACnet controller, capable of standalone operation or integration into a building automation system.
