Emerson Network Launches Liebert XDR
It is a fan less cooling with Innovative Rear-Door Heat Exchanger
Dec 26, 2011
As data center managers seek out new ways to design and support higher densities in smaller spaces, Emerson Network Power, a business of Emerson and a global leader in maximizing availability, capacity and efficiency of critical infrastructure, 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. 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.
"SMB 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, 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 growing business needs."
