Film Fills arthmost efficient filling media availablfor cooling towers. Thusagof 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 exchangby spreading thfalling water droplets into a thin molecular film wherthair can effectively contact the entire surface of the water film to carry away heat and mass.
ADVANTAGES
Minimum resistance to air flow Good distribution of water leads to turbulent mixing of air and water to maximize heat transfer.
Reduced fill height and greater cooling capacity results in lower power consumption.
Erosion and rotting resistant and long lasting (10-12 years of servictimin good quality water)
Self-supporting, high strength and self-extinguishing characteristics
Resistancto weather exposure (fungii/oxidation) ; Nearly impervious to chemical degradation by Alkali, acid, grease, fats, oils and biological attack
Easy to gluat site, reduces transportation cost.
