2.1  Functional description 

The cooling system consists of an air loop and a water loop. 

The fans of the cooling unit draw warm air from the rear section of the cabinet and into an 

air/water heat exchanger. The air is cooled down and then blown into the front area of the 

cabinet. 

Inside the air/water heat exchanger the heat energy of the warm air is transferred to the 

medium of water. The air/water heat exchanger is connected to an external reciprocal chiller 

unit (not supplied with the module), where the water is cooled down again. 

 

 

The water inlet temperature and the cooling water flow and the air flow determine the cooling 

capacity of the cooling module.
