Comparing "stainless steel fins," "copper fins," and "polyural"! A detailed explanation will follow.
Stainless steel fins deteriorate under severe salt damage conditions, and their low thermal conductivity is well known. Copper fins excel in thermal conductivity due to their close contact with copper tubes, but they are expensive, and the salt resistance of copper is not significantly different from that of aluminum, resulting in a deterioration rate that is said to be about half that of standard aluminum fins (deterioration between dissimilar metals can be avoided). Under conditions where standard aluminum fins deteriorate in three years, copper fins would deteriorate in about five to six years. Therefore, we propose our aluminum fin deterioration prevention coating, "Polyual." 【Features of Polyual】 ■ Provides semi-permanent protection ■ Maintains and restores the initial performance of fins ■ Effectively protects the air conditioning unit's function from salt damage and polluted gases ■ Thoroughly envelops and protects the fins from the inside to the ends ■ Shuts out the intrusion of salt damage and pollution *For more details, please refer to the PDF document or feel free to contact us.

Company information
BLYGOLD JAPAN Co., Ltd. is a company that specializes in preventing salt damage and other issues in air conditioning and refrigeration equipment. BLYGOLD was established in the Netherlands in 1976 as a manufacturer dedicated to preventing the deterioration of heat exchangers, developing its own rust prevention agents and application methods, and began operations in Japan in 2009. BLYGOLD JAPAN's "Polyual" is a technology that protects the aluminum fins of air conditioning and refrigeration units from corrosion such as salt damage. We take pride in the fact that, through maintenance contracts, it is possible to maintain the coating semi-permanently, significantly contributing to the performance maintenance and lifespan preservation of air conditioning systems in Japan.
