Liebert RackCooler
The Liebert XDR-W Rack
Cooler utilizes a cooling
unit that is attached to the
back door of the enclosure.
Fans in the module move air
from the equipment in the
rack, through a cooling coil
and expel it from the back of
the unit, chilled to the point
where the impact on the
room is close to neutral. This
makes the Liebert XDR-W an
ideal solution in applications
where the hot aisle/cold aisle
arrangement is not practical.
The Liebert XDR-W can be
configured to eliminate hot
spots or uneven heat loads
within the room.

The Heart Of The
Water-based System
The Liebert XDP-W Coolant
Pumping Unit is the key to the
performance, efficiency and space
saving of the Liebert XDR-W
RackCooler and Liebert XDK-W
water-cooled rack enclosure.
The unit houses the isolating heat
exchanger between the Liebert
XDR-W/XDK-W circuit fluid
and building chilled water, the
control valve, the dual redundant
pumps and the system controls. It
controls the fluid temperature to
always be above the actual room
dewpoint to avoid condensation.
The Liebert XDP-W can be used
with other brands of rack cooling
equipment.

Liebert XDO
The Liebert XD units work extremely well with the hot aisle/cold aisle design of raised floor applications by
efficiently drawing hot air out of equipment racks and moving cool air into the cold aisle.
Liebert XD Piping is pre-fabricated
distribution piping that is installed in
anticipation of a growing system. Liebert
XD Cooling modules are then added,
disconnected, or repositioned as required
and are quickly made operational with
flexible connection piping with quick-
connect fittings.
The Most Energy
Efficient Cooling
Available
Liebert XDR Rack Door
Cooling Module replaces
the back door of a server
enclosure, providing
cooling without increasing
the rack footprint. The
module uses the server
fans within the protected
rack to provide airflow,
providing the most energy
efficient design.
A New Way To Cool Hot
Servers
The innovative Liebert
XDS utilizes Integrated
Direct Heat Transfer™
technology to maximize
energy efficiency by
operating without cooling
system fans or server fans.
Patent-pending micro-
channel cooling plates
directly remove heat from
the server, eliminating
the need to expel air from
the rack and into the
data center. The system
removes up to 600W per
1U slot, for a total of more
than 20kW per rack and
provides an 80% energy
savings over traditional
cooling methods.
