Liebert XDK is a rack enclosure with integrated water-based cooling, developed by Knurr and manufactured by Liebert. This closed architecture solution circulates air inside -- completely sealed off from room air and environmental conditions. The server heat load is absorbed by the rack’s integrated cold water system, through a high-efficiency air-to-water heat exchanger in the bottom of the rack.

Liebert XDK 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. Supported by Liebert XDP-W coolant pumping unit.

Flexibility

• Operates as an autonomous server rack, independent from environmental conditions.
• Allows highest packing density for high performance servers, resulting in up to 80% floor space saving in the data center.
• Reduces room and building floorspace requirements.
• Provides user-friendly operation and service-optimized design.
• Operates quietly, ideal for applications where noise containment is required.

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.
• Provides n+1 redundant fans with temperature-dependent speed control.
• Triggers automatic front and rear door opener in case of overheating in the rack.
• Provides integrated alarm management.
• Allows optional remote monitoring with Liebert vEM-14 for temperature 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

• Improves cooling system energy efficiency up to 30%.
• Protects initial investment through system scalability.
• Optimizes energy efficiency with variable speed fans optimize.
