Indoor Heat Rejection for Smaller Cooling Systems

Liebert MCD condensing units are designed to be used in conjunction with the Liebert Mini-Mate2, Liebert DataMate and Liebert Challenger 3000 evaporator units, supporting effective data center cooling.

Liebert MCD Condensers are available in nominal capacities of 7kW to 28kW (2 to 8 tons). Air-cooled or water/glycol-cooled split system condensing units are mounted in the ceiling and connected to the evaporator unit by two refrigerant lines (four for 28kW (8-ton) model) and a low voltage control cable. The condensing unit, available in 50Hz or 60Hz, can be wired to a separate power source, or use the evaporator power source when close-coupled together.
