Splash fill consists of layers of horizontal bars or slats. When the warm water hits the surface of these bars, it spreads, breaks and forms small droplets. These work on the principle of causing the flowing water to fall through a grid of ‘splash bars/grids’ causing the water droplets to break up and increasing the contact time between water and air.
Splash fills maximize the water-surface to air interface. Instead of sheet surface, splash fills increase the water droplet surface. Splashing fills have been made of lath matrix or other forms of PVC or polyethylene. It is used in Industries which produce lot of poor-quality water. Thus, on use of splash fill the water is converted into smaller droplets any debris or dirt is separated out.
The V-Bar system has proven to be a superior system to upgrade Cross Flow cooling towers that have wood splash fill and for new construction NDCT and IDCTs where dirty water would clog film fills.
Perforated V-Bar is the most extensively used product in the industry. Thermal Care can supply the stainless steel or FRP coated wire mesh as well as the other components that are needed for the entire splash bar system.
The water droplets spread over the solid surface and perforated holes of the splash bar. The flowing water is held on the holes due to surface tension and forms a thin film. The water film formed over these rectangular holes has very low surface tension at its corners and thus a tendency to rupture frequently. During this process of rupturing the water film is broken into small globules, thus providing maximum heat transfer.
Thermal Care V-BAR clip design provides secure locking capabilities preventing wear on both the wire hanger and the fill. The tab locks provided on the V-bar prevent it from slipping once locked into place.

A newer solution for using splash fills in counterflow towers, the PP grid fill design offers smaller tower heights as compared to splash bar based counterflow towers.
The Optigrid is one of the more established splash fills used in counterflow cooling towers. Due of the small surface area exposed to the falling water, COOLOpti is a nonfouling fill, and has been used extensively in industries and plants where fill fouling had been extensive.
The grids are supported in uniformly spaced tiers throughout the cell width and length on stainless steel wires hung from supports installed under the water distribution system, and on polypropylene supports specifically designed to secure the grid to the wires. Each grid in each tier is secured to all adjacent grids by special clips that tie the entire fill assembly securely in place.
