Water-based Cooling Modules and Racks

Liebert DCW Water-based Cooling Modules and RacksWorks as a system with Liebert DCP Coolant Pumping Unit to supply cooling water to high heat density racks. The modules offer an alternative heat removal solution to critical applications where the hot aisle/cold aisle approach to cooling is not practical.

Liebert DCW water-based cooling modules allow you to take advantage of an existing building chilled water system, using the Liebert DCP coolant pumping unit to distribute the cooling water to the racks or to cooling modules mounted on the racks.

Liebert XDK-W is available in models that provide 17kW of cooling and 40U of rack space; and 25kW of cooling with 37U of rack space. 60 Hz or 50 Hz.

Liebert DCD rack cooler replaces the rear door of an enclosure,  providing cooling without increasing the rack footprint. The module uses the server fans within the protected rack to provide airflow, providing the most energy efficient design.
