A Quick Overview of Cooling Tower Fill
“Fill” is used in cooling towers to allow as much surface area for water as possible. Cooling tower fill is important because it puts water in contact with air for the longest amount of time possible. It allows the tower to completely use the water and spread it across more surface area.
The performance of the fill media function allows for:
- Quicker cooling time
- Longer residency
- Even distribution of water within the tower

What is important when looking for cooling tower fill?
Quality fill is crucial in the efficiency and effectiveness of the tower. It is important to look at the basin clearance, strength/rigidity, spacing of eliminators, and the ease of removal. We are spotlighting Opti-Pac 7500 film fill media, as this product is designed to replace OEM hanging fill sheets in crossflow cooling tower applications.
This particular fill meets or exceeds the designed tower performance. The media is fabricated from rigid, thermoformed PVC sheets that are solvent-welded for maximum strength and resistant to UV, rot, fungus, organic/inorganic solvents, acids, alkalis, and chemicals normally found in cooling tower waters.
The graphic below is a helpful introduction to fill, and we look forward to sharing more details about this media in a separate blog. In the meantime, click here for more in-depth info regarding cooling towers and fill.
