Precision Cooling for
Business-Critical Continuity™
Liebert DCD™ Rack Door Cooling Module
Chilled Water-based, Fanless Rack Door Cooling Module
The Liebert DCD is a fanless heat exchanger module that installs
as the rear door of an equipment rack. This chilled water-based
system provides up to 35kW of room-neutral cooling.
The Liebert DCD uses the server fans within the protected rack
to provide airflow through the unit, pushing hot air through the
door-based coil that cools the air and returns it to the room at
close to the same temperature as the air entering the rack. And
since the module always provides100% sensible capacity, the need
for computer room air conditioners to provide humidification is
significantly reduced, resulting in lower energy usage.
As many as ten Liebert DCD modules are connected to a single
Liebert DCP coolant pumping unit, which acts as an isolating heat
exchanger between the building chilled water source and the
circulating cooling water.
Flexibility
Replaces the existing back door on
IT racks from Knurr and other major
manufacturers
Requires minimal floor space
Door allows for full access to the servers
and equipment by opening 180 degrees
Supports both hot aisle/cold
aisle configurations and irregular
configurations
Allows adaptive and scalable expansion
without interruption of cooling operations
Higher Availability:
Ensures continuous operation of critical IT
systems under extreme heat conditions
Bottom or overhead
connections are
completely static – no
moving components will
interfere with opening
or closing the door.
Lowest Total Cost Of Ownership:
Operates with high energy efficiency – no
fans or moving parts requiring electricity
Fanless cooling module requires no
maintenance
Ideally Suited For:
Rack heat loads up to 35kW
Knurr IT Racks 600mm x 2000mm (w x h)
Adapter kits available for:
Liebert DCD Rack
Door Cooling Module
Other rack dimensions

Liebert DCD
The Liebert DCP coolant pumping unit creates an isolated secondary loop for
the chilled water fed Liebert DCD rear door cooling units. Liebert DCP may
also be used with other brands of rack cooling equipment.
The Liebert DCW Chilled Water-based Cooling System
The Liebert DCP coolant pumping unit is a part of the highly energy-efficient,
high heat density Liebert DCW chilled water-based cooling system. Designed to
support Liebert DCD rack door and Liebert XDK-W rack enclosure, Liebert DCP is
an isolating interface between the pumped water and the building chilled water
system. The advantages of creating this isolated secondary loop include:
Control of the secondary loop water temperature to always be above the
room dewpoint, thus eliminating the possibility of condensation. There is no
need to insulate the piping
Water quality control because this is a closed loop
Minimizes the impact of a water leak to the gallons in the circuit vs. the
entire building chilled water system
