3.1General function

The modular design facilitates the installation of 19-inch-wide equipment of varying depth.

Heat produced by equipment in the cabinet, such as servers, is removed by the cold water system integrated into the server cabinet. The cooling system is isolated from the server area, protecting the sensitive equipment from water damage.

The cooling system comprises a high-performance air/water heat exchanger, fans with fan control unit, fan-speed according to heat load.

The air circuit is closed such that no heat is emitted to the environment.

! CAUTION

Risk of improper operation. Can cause equipment damage.

The XDK works only if cold server feed air and heated server outlet air are fully separated. Height units not in use must be sealed with blanking panels.
