High Density Modular Data Center Cooling

Liebert XD delivers energy efficient air conditioners and flexible high density cooling solutions, designed to optimize data center infrastructure. These data center modular cooling solutions are available with open or closed architecture, and pumped refrigerant-based or water-based technology.

System-Matched Pumping Unit

Liebert XDP System-Matched Pumping UnitLiebert XDP Pumping Unit 130-160 kW

Liebert XDP is a system-matched pumping unit, designed to support to Liebert XDO, Liebert XDV, Liebert XDH, and Liebert XD CoolFrame spot/zone cooling units. When a building chilled water system is available, Liebert XDP pumping unit serves as an intermediary, isolating the building chilled water circuit from the pumped refrigerant circuit. It circulates the refrigerant to the cooling modules at a temperature always above the actual dew point to prevent condensation.

The Liebert XDP pumping unit is part of the highly energy-efficient, high heat density Liebert XD System, designed to support Liebert XDO, Liebert XDV, Liebert XDH, and Liebert XD CoolFrame. The system can cool more than 5400 W/m2, and utilizes pumped refrigerant, which is ideal for use around electronic equipment. Liebert XDP is an isolating interface between the pumped water and the building chilled water system.

The Liebert XDP is available in nominal capacities of 160 kW (46 Tons) and 130 kW (37 Tons) for 50 Hz applications.

Flexible Piping for Liebert XD System

Liebert XD Piping is prefabricated distribution piping installed in anticipation of a growing data center cooling system. Liebert XD cooling modules are added, disconnected, or repositioned as required and are quickly made operational with flexible connection piping and quick-connect fittings.

The Liebert XD Piping system is compatible with Liebert XDO, XDV, XDH and XD CoolFrame modules. The system allows data center cooling capacity to increase to more than 30 kW per rack.

The header distribution piping is available as 3.0 m segments with 5 or 10 ports, or 2.4 m segments with 2 or 4 ports. The flexible connection piping between the header distribution piping and the Liebert XD modules has quick fittings and is available in 1.2, 1.8, 2.4 and 3.0 m lengths.
