PVC Film Type Fills
Fill is a part of cooling tower that provides extra surface for heat transfer by evaporation. A fill packs consist of hot-formed corrugated PVC sheets bonded into modules covering the whole surface of the tower. Water flow down on fill surface in the form of a thin film layer. Meanwhile water film gives its heat to air that moving up in the cooling tower. The majority of heat transfer is performed by evaporation from the film surface.
