What Does Cooling Tower Fill Do?

Cooling tower fill is the primary heat-transfer surface inside a wet cooling tower. It spreads recirculating water into thin films or droplets and creates more contact area between water and air.

Film fill is commonly supplied as formed PVC sheets assembled into packs. Sheet spacing, corrugation, height and material affect airflow, water distribution, thermal performance and resistance to fouling.

For replacement projects, confirm the fill dimensions, sheet spacing, pack height, material and installation method before ordering.
