Cooling Tower Components

Film Fills

Film Fills are the most commonly used cooling tower fill type. By forming a thin layer of water over the fill surface, they increase the air-water interface and allow waste heat to evaporate at an accelerated rate.

Film Fills are classified into four categories and are designed with variations in surface structure, material, flute size, and sheet spacing to accommodate a wide range of applications

Cross-Fluted Fills

Cross-fluted designs provide high thermal performance. Utilizing the engineered microstructure design and have alternating fill sheets, allowing for excellent lateral water dispersion. High Thermal Performance achieved by.

Vertical-Fluted Fills

Vertical-fluted fills are designed to address applications with poor water quality. The design directs the water in a vertical path and large flute open.

Offset-Fluted Fills

 Offset-fluted fills utilize the water dispersion feature of cross-fluted fills, While the majority of the water film travels in a vertical path (like vertical-fluted fills) This keeps the water-film velocity high and reduces fouling potential. By combining these characteristics, offset-fluted fills are able to achieve high thermal performance low-pressure drop.

Cross Flow-Herringbone Film Fills

 Cross Flow Herringbone Fill uses a “herringbone” surface design engineered to distribute water evenly over the entire fill area for high thermal performance. Herringbone fills with integrated Inlet Louvers and Drift Eliminators complete this efficient, high-performance, crossflow media system.

Drift Eliminators

 Drift eliminators are used to capture water droplets in the air stream that otherwise would be lost to the atmosphere. Entrapping these droplets is important for not only conserving water as a resource but also to prevent cooling tower water from contaminating the area peripheral to the cooling tower.
The cooling tower industry uses drift rate to compare drift eliminator performance, a relationship that correlates droplet capture efficiency to the water circulation rate in a tower.

Cellular Drift Eliminators

 Water droplets are separated from the air drift at the three direction change points on the drift eliminator. The drift eliminators provide a rugged cellular structure formed by the solvent bonding of sinusoidal-shaped corrugated sheets. Individual S-shaped corrugated sheets are bonded with subsequent layers to create the structure. The entire area is thus divided into several smaller S-shaped mini zones

Blade (Profile) type Drift Eliminator

The Drift Eliminator uses the 3-pass system to air efficiency out of the drift eliminator while restricting the drift loss to less than 0.05% of circulating water.


The nozzle is designed specifically for use in counterflow cooling tower applications. Its unique spray pattern maximizes uniformity of water dispersion while maintaining low operating pressures. In addition to being an efficient, non-clogging nozzle.

Surface Grating

 Surface Gratings are used in the Cooling Tower to eliminate the Fill damages caused by the Hydraulic Impact. It also works as a Walkway during the Maintenance Work. Its interlocking capabilities makes easy to fix and remove.
