Knürr DCD

[:en]

The Knürr DCD is an air-to-water heat exchanger that is integrated into the rear door of a server cabinet. The heat exchanger serves to absorb heat loads from service racks up to 50 kW. The Knürr DCD can be configured with Knurr DCM cabinets or can be installed in other supplier cabinets. The design of the heat exchanger allows for an increase in the temperature of the chilled water.
