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.
