TP90-11: Film Fill Recent Research and Application Data

Film fill is the use of flat or formed sheets to provide a surface upon which liquid and air come in contact with each other to effect the exchange of heat. The only other fill options available to a cooling tower designer is the use of splash fill or combinations whereby heat exchange occurs on the surface of water droplets, or both. As film fill allows the -designer the opportunity to build a more compact, cost effective, energy efficient cooling tower; this type of fill material is receiving ever increasing acceptance 􀀒nd finding its way into more and more cooling tower applications.
