Cooling for network and server enclosures

  • Space-saving installation of the internal unit between the 482.6 mm (19˝) level and side panel
  • Optimum support of IT-compatible, “front-to-back” air routing
  • High level of fail-safeness guaranteed by availability of single and redundant variant
  • Cooling of TS IT racks and Micro Data Center

  • Refrigerant-based split cooling unit comprised of an internal unit (evaporator coil) and an external unit with integral compressor (inverter-controlled)
  • External unit is sited outside the building
  • Available in two power classes 3 kW and 6,5 kW

Benefits at a glance

  • Maximum energy efficiency by cooling the individual rack, rather than the whole room
  • Efficient operation thanks to EC fan technology
  • Optimum adaptation of the compressor output to the current heat load of the IT rack with inverter control
  • Ultimate security with optional alarm forwarding via CMC III

  • High availability designed for continuous, 24/7 operation
  • Absorbed thermal energy is emitted via the external unit directly to the ambient air
  • The internal and external unit are connected with refrigerant, data and supply lines
  • Control of the server inlet temperature
