Best HVAC/R Coil Coating Products

HVAC coils work within the air conditioning system of your home or business and are impacted by many factors. Typically environmental corrosion can hugely impact the way your system operates. Lucky for you there is a solution. Applying protective HVAC coil coatings to the coils and components of your equipment can greatly prevent environmental impact (such as salt air), as well as daily wear and tear. Ultimately these help to extend the life of your HVAC equipment and reduce energy consumption.

Choosing The Right HVAC/R Coil Corrosion Protection

There are many different products on the market that can be used as protective coatings for HVAC products. Whether this for corrosion resistance in marine environments, wastewater treatments, pools, food processing, or transit, there is a product for every industry. The coil coating product that you choose should be selected based upon a few criteria. The first is the corrosivity of the environment, while the next is the application method. Coil coating products can be applied to:

  • Finned tube coils
  • Condenser and evaporator coils
  • Refrigeration coils
  • Fans, blowers, grills, piping, and other components

 

The Best HVAC Coil Coating Products

Note: This list is in no specific order, as each product can serve a different purpose.

Technicoat

Technicoat is a great option when it comes to protecting equipment in salt spray environments. Essentially Technicoat is an air-dried and resin-based thermoplastic that is placed on top of a phenolic coating. It is typically around 3 millimeters thick and has tested for up to 1500 hours of continual salt water testing. The reason that Technicoat is one of the best coil coating products is that it requires minimal maintenance. All you need to prepare for is a wash down( with a pressure washer and soap, four times per month).

Heresite™

Heresite is an oven-cured, phenolic coating. It is dark brown, and an extremely flexible option to use for coating coils. The benefits of Heresite coating are numerous and the coating is often used to protect HVAC/R equipment in a variety of situations, including marine and offshore applications. Overall it is one of the most popular coatings used worldwide. Due to it being easy to apply, it is both abrasion and chemical resistant. Overall, it typically maintains a very thin thickness of under 2 millimeters and reduces the effects on heat transfer.

Blygold®

Is an aluminum pigmented polyurethane coating developed to protect air-cooled heat exchangers. Blygold meets all requirements for coating of (RTPF) condensers and coolers and offers excellent resistance against UV rays and airborne chemicals. Additionally, Blygold flexibility and unique properties offer excellent adhesion with negligible impact on heat transfer or pressure drops. Blygold has been tested to stand-up to over 11,000 hours of salt spray testing.

E-Coat

Also known as electrocoating, this is an eco-friendly coating that goes on similar to wet paint. It can be used on many products other than coils, including cars. E-Coat is the thinnest coating of all HVAC coatings, coming in between 0.8 to 1.2 millimeters. This is possible by using a computer-controlled complete immersion process. When it comes to using E-Coat on coils, it can be used to greatly extend their life.

Thermoguard

This epoxy uses a heat-conductive spray coating to ensure full coverage for all of your coil needs. Along with testing positive for protecting in marine environments, it also provides chemical resistance adhesion from dust and dirt. Thermoguard also helps to keep energy consumption levels lower, without the added maintenance. Being one of the thinner materials, it can be applied as thin as 1.2 millimeters.
