The condenser coils play a crucial role in the functioning of the air conditioners. It is imperative to maintain the condenser and evaporator coils and ensure that they do not rust or corrode.
Corrosion can damage the coils and cause leakage of the refrigerant thereby affecting the performance of your AC.
Coating the condenser coils with epoxy is the best way to solve this issue. The epoxy coating does not allow the accumulation of the acidic salts and humidity on the coils. The manufacturers refer to it as Blue Fin technology. Manufacturers like Blue Star use this procedure to protect them.
More than the salts and acid content, the water droplets sticking to the condenser coils can also cause the coils to rust. Hence, you need a unique coating that does not allow water droplets to settle down on the walls of the coils. This coating has low surface tension. Therefore, the water slips down and prevents the coils from rusting.
This unique technology is referred to as Gold Fin technology. These condensers are also known as hydrophilic condensers.
The difference between Blue Fin and Gold Fin technology
Gold Fin technology helps to protect the condenser coils from external damage due to the accumulation of water, acids, and other salts from the atmosphere. By doing so, this technology improves the overall life of the air conditioners. It also explains why the manufacturers of air conditioners with Gold Fin technology offer warranties up to ten years.
