Which materials are best suited to ensure durability and resistance?

The longevity of a cooling tower—or any other heat-rejection system—depends on the materials used and the operating conditions. Fiberglass (FRP) structures are now the standard for corrosion resistance and lightness in cooling systems, especially evaporative towers.

Stainless steel is chosen when dealing with aggressive water or high temperatures, while internal components such as fill media and drift eliminators are made of PVC or PP, offering high chemical stability and UV resistance. In dry systems, heat exchangers typically use copper or galvanized-steel tubes with treated aluminum fins.

Durability and resistance are definitely key parameters to consider during the selection process.
