3.0 DESCRIPTION
3.1 General 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.
