Cooling towers are selected base on the water flow rate, water inlet temperature, water outlet temperature and ambient wet bulb temperature. The performance of the cooling tower in terms of the temperature of the cooling tower outlet is a function of the wet bulb temperature of the ambient air and the tower type, size, design, and operation. Therefore you should select tower base on your operational data associated with the system along with tower manufacturers' selection tables or charts.
The temperature difference between the cooling tower outlet and the wet bulb temperature is referred to as the "approach". The temperature difference between the cooling tower inlet and outlet is referred to as the "range".
It should be noted that the tower size increases as the wet bulb rises and that the size increase becomes dramatic as the approach is less than 5.56C.
