Naturally occurring atmospheric conditions such as wind and hail from storms and erosion from sand blown in from the beach are contributing factors. But the exposure to salt air in these regions is by far the most destructive component to finned coils.
The growing population in coastal areas, combined with the warmer climate, creates a high demand for air conditioning equipment. A large number of these air conditioning systems utilize air-cooled plate fin condenser coils to reject the heat transferred from the conditioned space.
