2.0 GENERAL PRODUCT INFORMATION
The Liebert XDCF
™
is a self-contained module designed to cool Egenera’s BladeFrame EX cabinets
and equipment without exhausting heat into the room.
Liebert XDCF modules consist of a sheet-metal frame, coil and filter dryer. It has no moving parts
and needs no electricity.
The Liebert XDCF system consists of:
• Liebert XDCF modules—upper and lower models are available
• Liebert XD Flex Pipe (optional)—connects Liebert XDCF units to supply and return piping (ships
with Liebert XDCF)
• Liebert XD Piping—delivers R-134a refrigerant through flexible piping
• Liebert XDP or Liebert XDC—supplies R-134a refrigerant to Liebert XDCF modules
(see Liebert XDP or Liebert XDC user manual for required chiller or drycooler)
Liebert XDCF modules attach to the rear of the Egenera BladeFrame EX
™
cabinet. Heated air from
the BladeFrame cabinet is exhausted through the Liebert XDCF, which absorbs the heat. The cooled
air passes into the room and the heat is carried away by the Liebert XDCF’s R-134a refrigerant.

2.3 Room Preparation
The room should be well insulated and must have a sealed vapor barrier. The vapor barrier in the
ceiling and walls can be a polyethylene film. Paint on concrete walls and floors should contain either
rubber or plastic.
Outside or fresh air should be kept to a minimum when temperature and humidity must be tightly
controlled. Outside air adds to the cooling, heating, dehumidifying and humidifying loads of the site.
Doors should be properly sealed to minimize leaks and should not contain ventilation grilles.

NOTE
The vapor barrier is the single most important requirement for maintaining environmental
control in the conditioned space.
