Film Fills

Film Fills
for Cooling Towers


Film Fills are the most efficient filling media available for cooling towers. The usage of film fills – in both counterflow and crossflow cooling towers allows relatively smaller sized towers to cool an equivalent amount of water compared to cooling towers using splash fills. This results in the saving of not only capital costs for a new tower but also reduces operational costs on account of lower height and hence lower pumping costs.

Film Fills work on the principle of offering heat exchange by spreading the falling water droplets into a thin molecular film where the air can effectively contact the entire surface of the water film to carry away heat and mass.
