Don’t let corrosion ruin your condenser coil

A condenser coil in a rooftop condenser unit near the ocean is bound to corrode unless precautions are taken. The salt (sodium chloride) in the air corrodes the aluminum fins and casing, causing pockmarks to form, known as pitting. Pitting is made worse in areas with both high humidity and high temperatures. Corrosion initially causes lower efficiency, loss in capacity, and higher energy consumption. Over time, the corrosion gets so bad the condenser coil itself disintegrates. While estimates vary, the performance of a condenser coil in a harsh coastal area may be reduced by almost 50% or fail completely within a single year.

Rinsing salt off the condenser coil with water is one way to reduce corrosion, but it has to be done so frequently it doesn’t make sense. A better solution is to have a coating applied to a new condenser coil to prevent corrosion. Having a coating on your condenser coil will increase efficiency and reduce maintenance and operating costs. The coating will also significantly extend the life of the condenser coil compared to an uncoated coil, and the effect on heat transfer is negligible.

Because choosing the right coating for your specific situation is important, we offer several coatings at Emergent Coils, including Heresite and ElectroFin. Give us a call at 1-855-Coil-Now for your condenser coil needs.
