Emerson Network Power Liebert XDK-W, XD Water-Cooled Enclosure, Rack-Based Cooling Solution

btn_contact

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.

Features & Benefits

FEATURES BENEFITS
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.
High 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.
