With cooling towers, fill selection is a critical aspect in this regard. High efficiency film fill may seem the most desirable option. However, if poor water quality causes this fill to rapidly foul and plug, it may incur excessive maintenance costs.
Most cooling towers now utilize film fill to enhance air/water contact. Film fill, as the name implies, induces the cooling water to form a film on the material surface. The filming mechanism maximizes liquid surface area. A guiding principle behind fill design and selection “is to increase air-to-water contact, driving up convection and evaporative cooling while reducing pressure drop in the system”

*This type is a film fill system designed for counterflow towers
offering you several distinct advantages.
Crossed corrugations provide the surface area and turbulence to
develop efficient heat transfer. The corrugations inherently
establish uniform fill sheet spacing at 0.75.
*Using MC75 film fill in place of existing splash type fill in
counterflow towers usually means reduced fill height, which
translates into reduced pumping head. MC75 will also provide
greater cooling tower capacity, which means your current
performance level will require less fan energy.
*The fill pack depth(air travel) is variable to provide the proper
heat transfer area within a single fill layer. If another layer of
fill is necessary for situations where additional air travel is
required, it will be limited to only one. Limiting the number of
interfaces between packs minimizes restrictions that usually cause
fill clogging. MC75 counterflow fill can be hung from structural
members or it can be bottom-supported in virtually all counter-flow
cooling towers, regardless of a cooling tower's age or
manufacturer.
