The Liebert PDX direct expansion large room cooling unit is equipped with the most advanced industry cooling system technology, which allows the unit to provide thermal management efficiency for data centers and server rooms.
- 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 can be configured with modulating capacity compressors for a precise supply temperature control and annual consumption reduction, 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 allows the unit to reach significant levels of efficiency.
