Mode of action

The (evaporative) cooling tower is a wet water / air heat exchanger. In the open cooling tower the water to be cooled is brought into direct contact with the air. In this, usually in countercurrent flow extending operation, the down-flowing water emits heat to the rising air by evaporation and convection. In the cooling tower the water is evenly distributed by nozzles over trickling material (fillers).

Due to the evaporation process arise water losses. These losses must be supplied to the circuit at a suitable point.
