Cooling tower fill is a heat exchange media used inside cooling towers to improve air and water contact efficiency. Water spreads over fill sheets or fill blocks, forming a thin film while air passes through the structure, removing heat through evaporation. It is also known as cooling tower fill med

The most common materials are PVC cooling tower fill and polypropylene (PP) cooling tower fill. PVC fill media is widely used in HVAC cooling tower systems due to its cost efficiency, while PP fill media is preferred for high temperature or chemical resistant applications.

Film fill cooling tower systems use structured sheets to form continuous water films for higher efficiency. Splash fill cooling tower systems break water into droplets using fill blocks, making them more suitable for dirty or contaminated water conditions.

Selection depends on water quality, operating temperature, and system type. Clean water systems usually use film fill cooling tower designs, while industrial cooling tower fill with poor water quality often uses splash fill or anti fouling fill media. For outdoor systems, UV resistant cooling tower
