Lehmann CoolRack DX series.

 

Cooling IT is a central challenge when it comes to energy efficiency in the server room. Because every server room is different, there isn’t ONE single solution. That’s why Lehmann offers flexible cooling and air-conditioning systems that can be adapted to each application profile. With direct DX rack cooling, the racks can be easily installed in a decentralised location, as each rack has its own cooling solution that can also be implemented redundantly if required.

 

Lehmann IT cooling solutions – Everything from a single source.

The Lehmann CoolRack rack climate control is a directly cooled, air-conditioned server cabinet consisting of an indoor unit as a side cooling unit in the server cabinet and a split unit or chiller as an outdoor unit for outdoor installation.

 

All CoolRacks are equipped with the latest, low maintenance inverter technology from leading climate control vendors and can also be equipped with redundant climate control devices and automatic door openers as needed.

Lehmann CoolRacks are available in several models::

  • Standard CoolRack DX, cooling capacity of 3.5 kW - 14 kW
  • CoolRack DX with sound insulation, cooling capacity of 3.5 kW - 14 kW
  • CoolRack DX with modular cabinets, cooling capacity 3.5 kW - 14 kW (with 1 or 2 climate control devices)
  • CoolRack DX with redundant cooling unit, cooling capacity of 3.5 kW - 14 kW
