Emerson Network Power has introduced in India the Liebert XDR, a 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. The pumped refrigerant also eliminates any danger of equipment damage from water leakage. Air exits the Liebert XDR at approximately the same temperature as the air entering the front of the rack, neutralizing the heat created by the servers.

"SMBs contribute up to 40% of India’s IT spends but are faced with severe space and power constraints. The Liebert XDR saves on both as there is no need for fans to move heat across the room to wall or floor-mounted cooling systems," said BB Kale, country manger of cooling products at Emerson Network Power in India. "This translates into energy savings up to 48 percent compared to perimeter cooling, apart from the capital cost savings from not needing to expand or build a new facility to cope with the growing business needs."

Capable 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.
