Corrosion Coating Protection - who needs it?
Chances are that you might need the protection, if you live near the ocean or brackish river water. Salt Corrosion is the worst enemy of an AC system.
There are also several Treasure Coast communities that have ground water that is also very corrosive, and the sprinkler systems that slowly melt away your energy efficiency by destroying your outside condenser coil and ultimately cause premature coil and compressor failure.
Why do you need it?
When refrigerant is pumped through the condenser coil in your outside unit, is dissipating heat that is being moved from inside your home to the outside air. When it loses its ability to do so, the capacity on your system is reduced.
For example if you had a 3 ton (36,000 BTU) system with an unprotected coil, over time it starts to lose its capacity to transfer heat. Eventually your system will run more like 2.5 ton capacity. When this happens you become uncomfortable inside your home and pay electric bills that looks like a mortgage payments.
In a salt air environment unprotected coils will begin to corrode in just several months . This can cut the useful life expectancy by years.
How Does It Work?
P-413 Modified Baked Phenolic
Plasticizers have been added to this baked phenolic to make it more flexible for use on light gage metal like finned tube coils, fans, duct and other equipment that have flex in the metal. The P-413 baking phenolic will withstand exposure to practically all corrosive and chemical fumes and is a good thermal conductor. Coil manufacturers have indicated there is no need to add additional heating or cooling surface due to the presence of the Heresite corrosion coating
Florida’s Coastal areas are among the worst for corrosion in the Continental United States Salt Air, Acid Rain, Sulfur Dioxide, Nitrogen Dioxide. Corrosion and Severity Rate.
Testing: in after only 2 years of continuous use, an unprotected coil suffers constant decline in efficiency.Result: Operating cost for the unprotected coil more than doubled after only 24 months exposure.
Over Twenty-four months of ocean saltspray exposure: Uncoated coils showed a constant decline in operating capacity, while corrosion coating protected coils maintained close to their original operating efficiency. Operating cost for the unprotected coils rose 220%. The protected coils with virtually no capacity loss demonstrated 46% to 63% greater operating efficiencies(average 55%) than the uncoated coils. The unprotected coils showed a measurable loss in efficiency in the first 28 days. 12 AC coils were monitored: 6 coated, 6 uncoated. These results average the findings.
