In Cooling towers these act as Lungs of the CT. Water is cooled in & by the Fills. Wrong or Improper selection of media can spoil an otherwise perfect design.
The fill is available in various Materials like Treated Timber , PVC / Polypropylene, ABS, FRP & Even RCC.
Selection depends on variety of factor. Each fill has its own L/G value.
In a Cooling tower, water is cooled by:-
Splash Cooling or Film Cooling or A Mixture of Both Splash & Film Cooling,



The water flowing downwards is broken down into small drop lets ( for increased surface area) and as a result cooling is enhanced. The fill support grids for the splash fill are made of Stainless Steel (SS-304/ 316) wire. The fill material may be of Treated Timber Lathe or PVC bars or Polypropylene. It is helpful in case the water / air contains impurities or hardness or water has Carry over.
During Installation these are Hung using Stainless Steel Wire or Stainless Steel Wire Grids,


This fill is generally made of Virgin PVC material. The water flows along the film in a thin continuous film. Depending on the type used, it can provide surface area up to 12 times or more than that provided by normal Splash fill. Normally it can only be used with clean water which will not cause any scaling or deposits in fine flutes of this fill.
Generally used for Counter Flow Towers; in Power Plants, Steel Plants, Chemical Plants, Tyre Industry e.t.c. This is a high efficiency Fill media. As per requirement it can be transported in Glued Packs / Unglued Sheets.
