Back-of-Rack Cooling Module

Liebert XDR-W Rack Cooling Module

The Liebert XDR-W cooling modules are attached to the back of your selected

racks, drawing hot air from the rack and cooling it to the point where the impact

on the room is close to neutral, then discharging it back into the room. These

modules are connected to a Liebert XDP-W coolant pumping unit, which acts as

an isolating heat exchanger between the building chilled water source and the

circulating cooling water.

The modular and adaptive design of the Liebert XDR-W unit also allows it to be

easily added as the demand for cooling increases.

Flexibility:

Installs and configures easily
Allows scalability for
future growth.
Provides flexible configuration to
eliminate hot spots.

Higher Availability:

Provides built-in redundancy:
A dual pump in the coolant
distribution unit will keep the
fluid flowing; if a fan in the
cooling module shuts down,
the others keep running.
The pumping unit maintains the
coolant to the XDW-R at a
temperature always above the
actual dewpoint, to prevent
condensation.

Lowest Total
Cost of Ownership:

Operates with the energy-efficient
Liebert XDP-W coolant pumping
unit, which can support up to 12

W modules.
