High Heat Density
High heat density system delivers data center cooling for more than 30 kW per rack. Liebert XD 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. High density solutions are configured in 45 ton (160 kW) building blocks with spot cooling modules that range in size from 2.5 to 8 ton (9 to 30 kW).

Liebert XDV, XD Racktop Cooling Module, 8.8-10kW
Rack cooling module that mounts vertically on or above the IT rack enclosure, requiring no floorspace. It draws hot air from inside the cabinet or from the hot aisle. It then cools the air and discharges it down to the cold aisle.

Liebert XDO, XD Overhead Cooling Module, 17.2-20kW
Overhead cooling module that mounts directly above the cold aisle, requiring no floorspace. It draws in hot air from the hot aisle, then discharges cool air into the cold aisle where the equipment air inlets are located.

Liebert XDH, 22-30kW
In-the-row cooling module placed directly in line with the rack enclosures, and requires very little floorspace. Air from the hot aisle is drawn in through the rear of the unit, cooled, and then discharged horizontally through the front of the unit into the cold aisle.

Liebert® XD Pumping and Chiller Units, 130-160kW
The indoor Liebert® XD Pumping and Chiller Units include the Liebert® XDP and the Liebert® XDC units. These refrigerant-based systems support Liebert XD System spot/zone data center cooling modules, including the Liebert® XDO, Liebert® XDV, Liebert® XDH, and Liebert® XD CoolFrame units. The Liebert XDP is used between the cooling units and an associated heat rejection system, while the Liebert XDC is used between the cooling units and a chilled water system.

Liebert® XDU Coolant Distribution Units
Designed to support liquid cooling within high density environments, the Liebert® XDU Coolant Distribution Units are suitable for chip & rear door cooling applications that offer easy, cost-effective deployment in any data center. The Liebert XDU family offers multiple system designs that operate with and without access to facility water, allowing you to tap into the benefits of liquid-cooled servers to more efficiently support higher rack densities.
