Function For Cooling Tower Fill Media

Cooling tower fill material or cooling tower fill media is an significant element among the cooling tower parts. This element is, in a way, the most important cooling tower part as it is the identifier of cooling tower’s performance.

A higher contact surface between the cooling lilquid and working cooling tower filling media increases the rate of heat transfer between them. The main function of cooling tower fills in cooling towers is to increase this contact surface as much as possible to ensure an optimum heat transfer rate between the air and water for as long as possible.

Cooling tower fill media can be either of the film style type or splash style type. The film style cooling tower fills, which is used in most cooling towers, produce thick water strips that increase the rate of heat transfer and also larger evaporation rates. Cooling tower splash style fills are commonly used in crossflow cooling towers in which water cascades down on staggered slats that breaks up water droplets to increase the water surface area.
