Liebert XDO
High Density Cooling at Row Level

Pumped Refrigerant Based Cooling for High Heat Density Applications

The Liebert XDO overhead cooling module mounts directly above the cold aisle, requiring no floorspace. This overhead cooling unit draws in hot air through two opposite inlets and discharges cool air down into the cold aisle where the electronic equipment air inlets are located.

The Liebert XDO is a part of our high heat-density cooling product family that utilizes pumped refrigerant technology. The pumped refrigerant operates at low pressure in the system and becomes a gas at room conditions, making it ideal for use around electronic equipment. Since the Liebert XDO always provides 100% sensible capacity, the need for humidification is significantly reduced, further reducing energy usage and maintenance.

Smart Module technology:

Liebert XDO Smart Modules include integrated control boards that provide the following capabilities:

  • Monitor fan status on the module with an on-unit, red/green LED
  • Be alerted to the presence of condensation
  • Remotely shutdown the module via dry contact closures


Liebert XDO system works well with the hot aisle/cold aisle approach

The XDO system allows cooling-strapped data centers to add capacities without new construction. For Greenfield data centers, these systems can serve as dedicated cooling or can complement the baseline cooling and humidity control of traditional Liebert CRAC/H units.
