4.1 Liebert XDCF Standard Features
The Liebert XDCF is a self-contained module designed to cool Egenera’s BladeFrame EX cabinets and
equipment without exhausting heat into the room.
Upper and lower modules may be mounted on the rear of an Egenera BladeFrame. Liebert XDCF
modules use R-134a refrigerant. When attached to a fully loaded BladeFrame EX rack, each Liebert
XDCF module has a nominal cooling capacity of 10kW (2.8 tons; 34,000 BTUh). Performance is based
on:
• Entering fluid temperature—55°F (12.8°C) and
• Dew point—50°F (10°C) or lower.
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 (see Figure 49 below) consists of:
• Liebert XDCF Modules—upper and lower models are available
• Flex Pipe—connects Liebert XDCF modules to supply and return piping
• Liebert XD Piping—delivers pumped 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)
