Product Description

2.0PRODUCT DESCRIPTION

Congratulations on purchasing a Liebert XDF. The XDF is an integrated equipment cabinet with built-in cooling and intelligent control to protect mission-critical enterprise systems from extreme heat. The XDF provides an organized, secure, controlled environment for your sensitive electronic equipment. The unit is available in a variety of configurations to suit your electronic equipment’s environmental requirements.

The self-contained, air cooled Liebert XDF is intended for installation in open areas. Installation in closed-in areas, such as in a closet, alcove or similar space, requires field-supplied ducting, an exter- nal booster fan and sufficient makeup air. Contact your local Liebert representative before installing the XDF in an area that might inhibit heat dissipation.

The water/glycol cooled unit, however may be installed in closed-in areas, subject to clearances of three feet in the front, rear and right side. See Figure 6. This is possible because heat rejected from the XDF cabinet is carried away in the coolant.

2.1Operational Overview—Self-Contained, Air Cooled Model

The self-contained, air cooled XDF model employs a compressorized, direct expansion cooling system rated at 14kW to supply cooling air to rack-mounted equipment. A bank of fans circulates this cooling air through the electronic equipment in the XDF (see Figure 1). An evaporator coil extracts heat from the circulating air. That heat is transferred to a condenser at the top of the XDF and exhausted into the room.

The XDF’s backup ventilation system operates automatically if power fails or if any XDF cooling sys- tem component fails.
