1. Product Description

Completely sealed from room air, high density server racks inside the Liebert XDK-W utilize closed air circulation for cooling. The server heat load is dissipated into the process cold water system through an air-to-water heat exchanger in the bottom of the rack. Redundant high-performance fans drive closed loop air circulation in the rack’s interior, while servers are supplied with cold air at the front of the rack.

The Liebert XDK-W is a part of the Liebert XD high heat-density cooling product family. Key to the performance and space efficiency of Liebert XDK-W is the Liebert Pumping Unit, XDP-W. The unit houses the isolating heat exchanger between the Liebert XDK-W water circuit and the building chilled water, as well as the control valve, pumps and system controls. It controls the fluid temperature to always be above the actual room dew point to prevent condensation on the piping and the coils. Flexibility:

• Autonomous server rack; independent from environmental conditions. • Secure and reliable cooling capacity of up to 25kW. • Highest packing density for high performance servers, consequently, up to

80% floor space saving in the data center. • Reduced room and building requirements. • User-friendly and service-optimized. • Quiet operation is ideal for applications where noise containment is required.

Higher Availability:

• High performance air-to-water heat exchanger. • Channeled air flow in the rack for optimized efficiency. • Heat discharge via cooling water. • Fans with temperature-dependent speed control. • Fans, n+1 redundant. • Automatic front and rear door opener operates in case of overheating in the

rack. • Integrated Alarm management. • Highest possible leakage safety with strict separation of heat exchanger and

servers. • Optional remote monitoring with Liebert vEM-14 for temperature(s) and

operating status/alarms. Supports 10Mbit Ethernet connection. Provides Web interface using HTTP, user authentication, e-mail and paging notification, SNMP support including Nform and graphing.

Lowest Total Cost of Ownership:

• Up to 30% improved cooling system energy efficiency. • System scalability protects initial investment. • Variable speed fans optimize energy efficiency.
