Types Of Cooling Tower
Below is a brief overview to the main types of cooling towers available:
> Crossflow – the air and water flow effectively cross each other, the air flows horizontally and the water drops vertically through the fill media.
> Counterflow – air is pushed up vertically, counter to the water which is flowing vertically. This means it’s not possible to take advantage of the gravity flow so pressurised spray systems are used to spray the water onto the fill media.
> Forced draft – air is pushed, or forced, by blowers located at the base of the air inlet face.
> Induced draft – fans are used to pull the air up and through the fill media. The fans are commonly sited on the top of the cooling tower unit.
