Outdoor Condensing Unit, 3.5-28kW

The Liebert PFH propeller fan condensing units are designed to be used in conjunction with the Liebert Mini-Mate2, Liebert DataMate and Liebert Challenger 3000 evaporator units, supporting efficient data center heat management.

The Liebert PFH Condensers are available in nominal capacities of 3.5 to 28kW (1 to 8 tons). Split-system condensing units are connected to the evaporator unit by two refrigerant lines (four for 28 kW (8 ton) model) and a low voltage control cable. The condensing unit, available in 50 or 60Hz, requires a separate power source and an outdoor disconnect switch.
