Splash Fills VS Film Fills in Cooling Towers

Splash Fills VS Film Fills in Cooling Towers 

Film fill

Film fill is made using thin sheets of PVC which are placed very close together. This creates a very large surface area which allows hot air to circulate and come into contact with the film of material. This cools the water by increasing the rate of heat transfer. A film fill is designed to cool water, which needs to be fit for human consumption. Any debris within the water will collect on the film.

Splash fill

A splash fill is made using many layers of slats or bars. When hot water comes into contact with the slats or bars, it breaks down into smaller particles. As these particles form, they allow for an increased contact between the water and air which is contained within the atmosphere. This leads to an acceleration in the rate of evaporation and cooling. Splash media used to be made using wood, but more modern designs are manufactured using PVC. PVC allows for a greater rate of heat transfer. Splash fill is normally used in industries which produce a lot of excess water which is of poor quality. Because the water is converted into smaller droplets any debris or dirt is separated out.

Film fill vs Splash Fill

While both film fill and splash fill can facilitate the cooling and evaporation of water within a cooling tower, they have different advantages and disadvantages. 

Film fill produces a more efficient heat transfer as it generates a bigger surface area. However, it generally has a shorter lifespan due to increased wear and tear as it is constantly exposed to high-temperature water.

A Splash fill is ideal if you operate a cooling tower which requires the recirculating of low-quality water which has a high level of solid material in it. The metal grills and bars used in splash fill make it much more resilient and effective when exposed to high temperatures.

A cooling tower forms a vital part of manufacturing processes. If you require any further information, you should contact a professional cooling tower company.
