2.3 Liebert CRV Description
The Liebert CRV is a precision cooling unit available in compressorized (air-, water- or glycol-cooled) and
chilled-water configurations to be installed within a row of high-density computing racks in a “hotaisle-
coldaisle” configuration.
Air enters the rear of the CRV from the hot aisle, is filtered, cooled and conditioned, then discharged into
the cold aisle. The CRV provides all the necessary functions of a standard Thermal Management unit,
including cooling, heating, humidification, dehumidification, air filtration, condensate management,
temperature control, alarm monitoring and data communication. (The 300 mm [12 in.] models do not
provide heating, humidification or dehumidification.) The CRV is optimized for maximum cooling capacity
in a minimal footprint.
