Emerson Network Power, a business of Emerson, has
introduced the Liebert XDR in India. Liebert XDR is a rear-door heat exchanger
that removes heat from IT racks before it 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 percent 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. 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,” said BB Kale, country manger, cooling products at Emerson Network Power in India.
The Liebert XDR is designed to cool up to 20 kW of rack
load, 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.
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. Pumped refrigerant from a
Liebert XDP or Liebert XDC enters the fixed frame and passes through an
innovative hinge to the door. The Liebert XDR can be utilized with existing
Liebert XD installations, using the same flexible connections and hard piping.
