Liebert XD Water Based Cooling Modules and Racks

Liebert XD Water Based cooling modules work as a system with Liebert XDP-W Coolant Pumping Unit to supply cooling water to high heat density racks. The modules offer an alternative to critical applications where the hot aisle/cold aisle approach to cooling is not practical.

Liebert XDK-W is available in models that provide 17kW of cooling and 40U of rack space; and 25kW of cooling with 37U of rack space. 60 Hz or 50 Hz.

Liebert XDR-W rack cooler attaches to the back door of an enclosure. Fans in the module move air from the rack equipment through a cooling coil and expel it from the back of the unit, chilled to the point where the impact on the room is close to neutral.

Flexibility:

	Reduces room and building floorspace requirements.
	Provides user-friendly operation and service-optimized design.
	Solves rack cooling issues where hot aisle/cold aisle
	approach is not practical.
	Operates quietly, Liebert XDK-W is ideal for applications
	where noise containment is required.
	Offers 60 Hz and 50 Hz models.

Higher Availability:

	Channels air flow in the rack to optimize efficiency.
	Discharges heat via cooling water, with high performance
	air-to-water heat exchanger.
	Separates heat exchanger and servers for highest possible
	leakage safety.

Lowest Total Cost Of Ownership:

	Leverages existing building chilled water system.

Ideally Suited For:

	High-density equipment requiring precise cooling & protection
	Communication enclosures
	Data centers
	Server farms
