A total of 240 GRP-FRP blades belonging to the cooling water towers of İzDemir Enerji Elk. Üretim Inc. were maintained and refurbished by CorCoat. GRP-FRP composite blades, preferred in cooling water towers for their lightweight structure and chemical resistance, may deteriorate and become damaged over time. This condition requires material repair and may also cause system imbalance due to weight variations. With the fully revised and refurbished GRP-FRP blades provided by CorCoat, efficiency in the cooling water towers has been improved.
