Fin–tube coils, which typically combine aluminum fins with copper tubes, are widely used in air-conditioning and HVAC systems. Corrosion in these components leads to reduced heat-transfer performance, efficiency loss, leakage, and shortened service life. The following sections present practical, preventive engineering methods for protecting these coils.
Heresite coating on coil aluminum fins enhances corrosion resistance and extends the lifespan of HVAC systems. This protective coating is particularly crucial in environments with high humidity, aggressive chemicals, or coastal areas where exposure to salt air is prevalent. The application of Heresite coating involves a meticulous process that ensures complete coverage on the aluminum fins of the coil. This coating acts as a barrier, preventing corrosive elements from coming into direct contact with the metal surface. As a result, it...
