Comparison with stainless steel fins and copper fins

Comparing "stainless steel fins," "copper fins," and "polyural"! Detailed explanation provided.

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 much 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 will 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 from salt damage and polluted gases ■ Protects thoroughly from the inside of the fins 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.
