What is the purpose of epoxy coating on evaporator coils?
Because they are thicker, epoxy coatings will reduce heat transfer from the air to the refrigerant in the coil, and thus cause a decrease in system efficiency and capacity. Epoxy coatings might best suit new installations where heat transfer losses are accounted for in the system design specifications.
How do you prevent AC coils from corroding?
How to Prevent Coil Corrosion
- Have an anti-corrosive coating applied on the coils once they’re clean.
- Install a whole-house air cleaner on your HVAC system to capture and eliminate airborne VOCs.
- Rinse down your outdoor unit with the hose every month to limit the buildup of potentially-harmful debris.
What are the two common types of coil corrosion?
The two most common forms of coil corrosion are pitting and formicary. These two corrosive processes can occur in as little as a few weeks after installation. More typically, corrosion will begin appearing within a one-to-four-year period.
What causes AC coils to corrode?
Corrosion of the copper tubing in the coil from the outside in is the most common cause of evaporator coil leaks. This corrosion happens when formic acid accumulates on the coil as a result of the interaction of water, copper and volatile organic compounds (VOCs) in your indoor air.
How do you protect a cooling coil?
Are epoxies cheaper than phenolics?
Epoxy resin countertops may be the more durable of the two options, but phenolic resin wins when it comes to price. Because it is somewhat less intensive to make, phenolic resin tends to be less expensive. Additionally, because it is less heavy, it is generally more economical to have shipped.
Why choose Heresite coating for HVAC?
Heresite protective coatings have been extensively tested for corrosion resistance. Our coating products for HVAC-R and Radiators have been shown to extend the life of HVAC-R equipment used in a wide variety of environments and industries including: See our case studies to learn more about the real-world results of using Heresite coatings.
What is Heresite p-413 coating?
See our case studies to learn more about the real-world results of using Heresite coatings. Heresite P-413 is a thin film, high performance coating used principally for coil and radiator heat exchangers as well as other air and fume handling equipment fabricated of light gauge metals.
Are HVAC-R coils protected from corrosion?
When placed in harsh environments, HVAC-R coils are susceptible to environmental damage, which shortens the life of the unit. Heresite protective coatings have been extensively tested for corrosion resistance.
What is the difference between Heresite es-606 and vr-514?
Heresite ES-606 is a high-performance spray-applied coating used to protect heat transfer equipment and components – including, but not limited to, coils, cabinets, and copper piping. VR-514 is a thin film, air dry phenolic with excellent resistance to corrosive fume atmospheres and is particularly good in marine and salt air environments.
