Liebert XDP-W pumping unit is part of the the highly energy-efficient, high heat density Liebert XD data center cooling system, designed to support Liebert XDR-W rack cooler, and Liebert XDK-W rack enclosure. Liebert XDP-W is an isolating interface between the pumped water and the building chilled water system. Liebert XDP-W may also be used with other brands of rack cooling equipment.
The water-based Liebert XDP-W pumping unit houses the isolating heat exchanger between the Liebert XDR-W or Liebert XDK-W and the building chilled water. It circulates the chilled water to the cooling modules at a temperature always above the actual dew point, to prevent condensation.
