Emerson Network Power Unleashes Liebert XDR Fan-less Cooling Solution

Emerson Network Power has introduced the Liebert XDR in India. Liebert XDR is an innovative rear-door heat exchanger that removes heat from IT racks before it even enters the data center. Liebert XDR packs in high density servers in a small footprint thereby eliminating the need for expansion or new facilities in Small and Medium Businesses (SMBs). 

The Liebert XDR micro-channel heat exchangers are mounted in a moveable door, which is fixed to a frame attached to the rear of the rack. It relies on server fans for hot air movement across a cooling coil, utilizing a pumped refrigerant that is 700 percent more efficient at removing heat than water.

Able to accommodate both new and existing racks, the Liebert XDR is designed to cool up to 20 kW of rack load, even in environments that may not be arranged in a hot aisle/cold aisle configuration. The sleek construction of the Liebert XDR allows the entire cooling unit to be less than six inches deep. The door opens more than 100 degrees, for full access to the internal servers and other equipment, and allows for side-by-side placement of racks in open and closed positions.

Uniquely, the Liebert XDR includes a flexible connection of hard-piped, pumped-refrigerant lines through the rack door's hinge pivot points, which enables it to be robust and leak-free through more than one million repeated door openings and extended periods of time with no movement. These overhead piping connections are completely static - no moving components will interfere with opening or closing the door.
