General product information

2.0GENERAL 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.

2.3Room 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.

NOTE

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

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.
