Hybrid cooling towers of the classical design with separate wet and dry sections have constituted a proven technology in the recooling field for approximately the past two decades. The round type of construction however is only used for high thermal performances, in particular for power stations, and is at present less well known. Another feature of this type of cooling tower is the separate machine sets allocated to the wet section and dry section respectively as well as automatic operation to an optimized overall performance. The advantageous features of the round type of hybrid cooling tower compared to the cell-type construction are less space required, lower operating cost, and lower power consumption. In the future the round construction will therefore increasingly replace the currently predominant cell type construction for large power station applications.
