Kaltra's Rack cooling for high-density IT applications

In its portfolio of IT cooling products, Kaltra offers rack cooling solution to target high heat density data centers and local IT installations.

One solution is In-Rack CW/P – a passive cooling door distinguished by fail-safety, which is of paramount importance to colocation and telecom applications. A second alternative is In-Rack CW/A, an active cooling unit equipped with fan blowers and intended to replace the rear rack door.

When the passive cooling doors’ cooling capacity is not enough to cope, Kaltra offers In-Rack CW/A equipped with fan blowers as a solution. In-Rack CW/A is equipped with variable-speed fans to support varying heat load, can be configured for the 2N redundancy model, and features dewpoint control.

In-Rack units are compatible with standard server cabinets with widths of 600 or 800mm and can be attached to the rack either directly or via an adaptor frame.

Both solutions are based on microchannel coils. This solution has a number of practical advantages for both new installations and retrofit applications:

  • Low weight, compared to systems equipped with air-water heat exchangers of other art
  • Small unit depth
  • Low water volume

Yet another customers’ concern is the risk of leakages. For In-Rack doors, the risk is minimized through and the use of a drain pan and pipework shells. Most of the identified leakages are caused by units operating improperly, for instance, with exceeding working pressure or installation errors like inadequate grounding, often leading to electrochemical corrosion and, in turn, to leaks. By hiring experienced technicians who are committed to installation, inspection, and commissioning works, customers will get the assurance that the correct steps are taken to avoid leakage issues during the cooling units’ lifecycle.
