Design

LCU DX 3 kW redundant

Benefits

Space-saving solution by installing the redundantly designed internal unit in the VX IT server enclosure or the Micro Data Center

Applications

Cooling unit for VX IT server racks and for Micro Data Centers

Function principle

The redundant variants have two cooling circuits and controllers inside the internal unit, plus two inverter-regulated external units. The fault and operating hours changeover allows regular switching between the two external units, and ensures automatic changeover in the event of a malfunction or failure.
