FRP cooling towers are used in industrial cooling applications where low weight and corrosion resistance are important. Glass-reinforced polyester, known as CTP in Turkish, combines glass fibres with a polyester resin matrix. FRP, short for fibre-reinforced polymer, is a broader category that includes different fibre and resin combinations.
Rust-Resistant Composite Construction
The non-metallic composite casing does not rust like steel. However, chemical resistance depends on the resin type, fluid composition, concentration and operating temperature. Any metal fasteners and structural components within the tower require separate consideration.
Low Weight and High Strength-to-Weight Ratio
FRP combines low weight with mechanical strength. With an appropriate design, it can simplify transport, lifting and installation while helping reduce equipment loads on supporting structures. Structural calculations must also account for the tower’s water-filled operating weight and operational loads.
UV and Outdoor Exposure Resistance
Suitable gelcoats, protective surface systems and UV-stabilised resins improve resistance to sunlight and outdoor exposure. For acidic atmospheres or environments containing industrial gases, resin selection must match the expected chemical exposure.
Typical Applications
FRP cooling towers can be considered for chemical and petrochemical facilities, geothermal energy applications and industrial sites with significant corrosion risks. For systems using seawater or well water, suitability should be assessed through water analysis and the material compatibility of all tower components.
