Liebert XD Cooling Modules—Liebert XDO, Liebert XDV, Liebert XDH and Liebert XDCF

4.3Liebert 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 39 below) consists of:

Liebert XDCF modules—upper and lower models are available

Flex pipe—connects Liebert XDCF units 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)
