3.Description

3.1General function

CoolTherm complies with the conditions of EN 60950

The modular design facilitates the installation of all 19“ equipment of varying depth.

Heat produced by installed equipment (e. g. servers) is reliably removed using the cold water system integrated into the server cabinet. The cooling system is inherently safe because water cannot reach the server area.

The cooling system comprises a high-performance air/water heat exchanger, fans with fan control unit (fan-speed according to heat load) for the ducted supply of air and cold water connection. The air circuit is closed such that no heat (thermal load) is emitted to the environment.

Attention! CoolTherm only works if cold server feed air and heated server outlet air are fully separated.

Height units not in use have to be sealed using blanking panels.
