Liebert » High Heat Density Cooling Solutions for Racks, Spots and Zones
  Liebert XD™ System
Precision Cooling System
Liebert energy-efficient and flexible high heat density cooling solutions are available with Open or Closed architecture and Pumped Refrigerant-based or Water-based technology.
Pumped Refrigerant Coolant System
High heat density system can cool more than 30 kW per rack
Offers floor-mount, rack-mount and ceiling-mount configurations
Utilizes pumped refrigerant, which is ideal for use around
  electronic equipment
Enhances the hot aisle/cold aisle approach to cooling
  allowing networking of multiple mission-critical cooling units.
Liebert XD Refrigerant-based Cooling Modules
High heat density cooling modules
Mount above, between or on racks
Use pumped refrigerant technology
Require little or no floorspace
Liebert XD Pumping and Chiller Units
Indoor refrigerant pumping and chiller units
Connect directly to Liebert XD cooling modules via the pumped
  refrigerant circuit
Circulate refrigerant to the modules at a temperature
  always above the actual dewpoint
Liebert XD Piping System
Pre-fabricated distribution piping
Install piping in anticipation of future growth
Flexible connection piping and quick-connect fittings allow
  addition or repositioning of cooling modules
Allows room cooling capacity to increase to more than
  500Watt per square foot
Water Coolant System
Water based high heat density cooling solution
Offers rack enclosure and door-mounted models
Leverages existing building chilled water loop
Liebert XD Water Based Cooling Modules and Racks
Water-based high heat density systems
Full enclosure system, or back-of-rack-installed module
Use pumped refrigerant technology
Leverage existing building chilled water loop
Compatible with Liebert coolant pumping unit
Liebert XD Water Pumping Unit
Isolating pumping unit
Serves as an intermediary between the building chilled
  water circuit and the module/rack circuit
