Weatherproof outdoor HVAC coils

Coil Shield is a conformal molecular barrier that protects condenser coils from corrosion, mineral scale and other harmful weathering effects, including salt spray corrosion.

Corroded HVAC unit

Corrosion

Coil and fin corrosion inhibits heat transfer, making the unit less effecient and more exspensive to run. There are multiple causes for corrosion, such as moisture, chemicals, and acids. Eventually as corrosion progresses, refrigerant begins to leak and ultimately the unit fails.

Salt air corrosion

Coast Corrosion

Coastal areas have high salt content. When droplets of salty ocean water evaporate, the salt content is left floating in the air. When salt settles on HVAC fins and coils it inhibits heat transfer and accelerates corrosion.

Mineral Scale on coils

Mineral Scale

All water, regardless of location contains minerals. When water evaporates it leaves behind minerals that develop scale on condenser coils. Buildup on condenser coils inhibits heat transfer, which lowers unit efficiency

Coil Shield is the easy spray on solution that provides long-term protection against scale and corrosion, without inhibiting heat transfer.

Coil Shield

  • Preventative Product
  • Advanced Technology
  • Independently Tested
  • Protects against scale and corrosion
  • Protects against salt-spray corrosion
  • One coating can last a year or longer
  • No loss of heat transfer
  • Low VOC

Independent Testing

Coil Shield was put to the test in an accelerated weathering chamber. The test inflicted salt spray, UV light exposure, heat, and industrial chemical exsposure.

Independent studies in an accelerated weathering chamber showed that Coil Shield treated coils performed for at least 4,000 hours. The equivalent of a year in the harshest weather conditions. At this point the test was stopped. The coils treated with Coil Shield were still structurally intact while untreated fins were falling off copper tubes.

Coil Shield was also field tested in evironments such as a Florida summer, with over 4000 hour results!

 

Coil Sheild is easy to apply

Anyone can easily apply Coil Shield in a matter of minutes. Thoroughly clean the unit, then spray Coil Shield on outdoor coils. It's that easy. Plus Coil Shield is water based with a low VOC, making it safe to spray

One gallon coats a 50 ton coil

Available in:

  • 16 oz
  • Quart
  • Gallon

    • Coil Shield is a great value.

  • Mineral Scale, Salt Spray, and corrosion cost money from the start
  • Salt film, mineral scale, and the early pitting stages of corrosion make the unit work harder to produce the same results
  • A harder working unit means increased energy consumption and higher energy bills
  • Advanced corrosion or unit replacement are even more costly and inconvenient too.

    • Don't waste money on higher energy bills or unit replacement

    Coil Shield prevents problems before they start. 

    No one wants to be without cool air during the hot days of summer. Prevent mineral buildup, corrosion, salt-spray corrosion, and the inconvenience of unexpected unit failure with Coil Shield.

    Coil Shield is a great product for all AC units to prevent mineral scale and corrosion. It is a must for coastal units to prevent salt spray corrosion.

    FAQs

    What does Coil Shield do?

    Coil Shield is engineered to stop the corrosive effects of coastal salt spray on condenser coils. It is also effective against mineral scale

    How long does Coil Shield last?

    Under severe conditions coil shield should be applied yearly, and less often in milder conditions.

    How does an accelerated weathering chamber work?

    Coil Shield treated coils were exposed to salt spray, UV light, high temperatures, and an industrial atmosphere containing sulfur dioxide. At the end of 4000 hours untreated fins were falling off copper tubes, while coils treat with Coil Shield were still structurally intact.

    I send my coils out to have them epoxy dipped. How does Coil Shield compare to epoxy coatings?

    Check salt-spray life data with your coating supplier. Coil Shield likely meets or exceeds their testing times.

    I spend $500 to $1,000 per coil for epoxy coating. How does Coil Shield compare?

    Coil Shield can be applied on location with no special equipment or training. Costing an average fo $20 to $100 per condenser coil depending on size.

    How does Coil Shield compare to the application times of DIY epoxy or silica kits?

    Epoxy or Silica kits can take 3 or more hours per coil. Coil Shield only takes 10 to 15 minutes per coil.

    Epoxy and Silica coatings reduce condenser heat transfer, and raise energy consumption. How does Coil Shield compare?

    Measurements show no heat transfer reduction with Coil Shield.

    Is Coil Shield flammable?

    No

    What size is Coil Shield available in?

    16oz, quarts and gallons. One gallon covers a 50-ton coil.

    Coil Shield Application Instructions

    SHAKE WELL BEFORE USING. DO NOT FREEZE

    Directions:

    Preparing the Surface

    Clean coils well using a mild alkaline cleaner like Instant Powder Kegs. Rinse thoroughly with water for 3 to 5 minutes, until all foam, dirt and cleaner residuals are washed away. Rinsing is important, pay close attention to the bottom of the coil. Coils must be free of all dirt, detergents, and oils before application.

    Applying Coil Shield

    Apply Coil Shield to wet or dry coils in a fine mist using a garden or pump sprayer. Running the system fan on low during application helps pull Coil Shield into interior surfaces for more complete coverage. Unit can be put into service immediately.

    FIRST AID: SEE MSDS

    EMERGENCY TELEPHONE: 1-800-255-3924

    KEEP OUT OF REACH OF CHILDREN

    Inhalation:

    Remove person to fresh air.

    Skin:

    Remove contaminated clothing, wash affected area with soap and water.

    Eyes:

    Flush eyes with water for 15 minutes.

    Ingestion:

    Give two glasses of water, DO NOT induce vomiting. Seek medical attention.

    Coverage

    1300 square feet per gallon. 1 gallon is enough to cover the front and back of a 50 ton coil
