Liebert® DCD Water-Cooled Passive Rack Door, 35 kW
The Liebert® DCD chilled-water cooling unit is a highly efficient heat exchanger module that mounts on the rear of an IT rack and provides up to 35kW of room-neutral cooling. By utilizing the IT equipment fans inside the rack, the DCD passive door requires zero energy, maximizing the efficiency of your high-density system. The DCD can be supplied by either the existing chilled water system or by a coolant distribution unit, such as the Liebert® DCP, providing flexibility during installation.

Specifications
The Liebert® DCD chilled-water cooling unit was designed specifically for high heat density applications where the challenges of reducing energy consumption and increasing processing capabilities are the top priority for data center managers. Mounting on the rear of the rack, the Liebert® DCD brings cooling directly to the source and takes up zero additional IT floorspace, all while providing 35kW of room-neutral cooling using a chilled-water heat exchanger. By utilizing the fans from the IT equipment inside the rack to provide airflow over the heat exchanger, the DCD passive door requires zero power to remove the IT heat load, maximizing the efficiency of your high-density system. The DCD can be supplied by either the existing chilled water system or by a coolant distribution unit, such as the Liebert® DCP, providing additional flexibility during installation.
