Liebert PDX is available both in air cooled and water cooled versions to suit various site installation requirements. It also allows multiple freecooling modes of operation (Direct Air, Indirect Water, Chilled Water on Freecooling Chiller and Liebert® EconoPhase™ pumped refrigerant economizer) increasing its ability to adapt to diverse application demands
The Liebert® EconoPhase™ pumped refrigerant economizer is compatible with Liebert PDX and Liebert MC microchannel condenser to improve thermal management and control, while drastically cutting energy costs and lowering pPUE
 The unit’s Digital Scroll configuration, instead, is responsible for modulating cooling capacity while the fresh air economizer function, operated by the iCOMTM control, is adopted when outside air temperature is colder than the return temperature
In addition, the combination of R410A refrigerant, Electronic Expansion Valve (EEV) and new generation Liebert® EC Fans 2.0 all allow the unit to reach significant levels of efficiency


Liebert PDX is the highest performing floor mount direct expansion unit in its range, delivering efficiency of up to 65%
 Suitable for all data center environments with a wide range of configurations to meet all installation requirements 
 Liebert PDX is ideal for data centers facing load and temperature variations, such as those typical of cloud computing environments
