  • Banking, Financial and Insurance
  • Broadcast and Entertainment
  • Data Center/Colocation/Hosting
  • Government
  • Healthcare
  • Oil and Gas
  • Power Generation
  • Telecom

Sustainability Spotlight

  • Inverter scroll compressor technology is the best solution in terms of variable cooling capacity since it improves annual efficiency by up to 35% compared to a fixed speed compressor unit even when requested cooling load is low, such as in the early stage of a data center life, or when the IT equipment usage is subject to big fluctuations.
  • The latest generation of EC fans technology, which are compliant with the ErP directive, results in highly efficient units.
  • New generation of heat rejection condensers equipped with EC fans to reduce even further power consumption and simultaneously reduce noise emissions.
  • The integrated EEV valve optimizes power consumption, despite variations in internal and external ambient temperatures.
  • Available with direct and indirect freecooling options, with the EconoPhase pumped refrigerant economizer being the most efficient indirect freecooling system since compressors' working hours are minimized resulting in increased energy savings.

Features

Installed Liebert PDX in a server room cooling system
 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.
