RectorSeal Introduces GulfClean Coil Clean, Salt Reducer for Coastal HVAC Units      

RectorSeal introduced GulfClean, a Modine CIS Coatings-approved two-step coil cleaner and salt reducer application for protecting coastal area residential and commercial HVAC equipment and their factory-applied coil coatings.

GulfClean was developed by RectorSeal through the specifications of a partnership with Modine CIS Coatings–division of Modine Manufacturing. Modine CIS Coatings now authorizes and mandates GulfClean applications every six months to coastal area units treated with its Electro-Fin E-Coat and Insitu Spray Applied Coating to maintain the coatings’ five-year warranty. The two-step process is also safe and recommended for maintaining most manufacturer’s coils and coatings from salt corrosion, including RectorSeal’s recently-introduced GulfCoat, an HVAC protective coil coating sold in 12 ounce aerosol cans for contractors to field or shop-apply.

GulfClean’s Step-1 Coil Cleaner and Step-2 Salt Reducer are available in one gallon containers from most HVAC/R wholesale distributors. Each step requires less than 10 minutes to apply and rinse.

GulfClean Coil Cleaner is an environmentally friendly, biodegradable, non-acid and non-caustic foaming cleaner that attacks dirt and salt, but is safe for evaporator, condenser and refrigeration coil metals and coatings, as well as the service technician applying it. The straw-colored solution is typically diluted with one to three parts water (depending on coil soiling), applied with a hand pump-up sprayer and rinsed with water.

GulfClean Salt Reducer is a biodegradable, non-flammable and VOC-free solution that’s safe for removing soluble salts, but without interfering with coil protective coating adhesion on evaporator and condenser coils. Manufactured in a blue color to differentiate from the cleaner, the salt reducer is typically diluted in a 50:1 to 100:1 ratio (depending on unit proximity to coasts) and applied with a hand pump-up sprayer and rinsed within 10 minutes.

Other GulfClean features include:

  • Step-1 will not chemically attack or corrode coils, surrounding metal, other HVAC equipment components or adjacent roofing materials
  • Applicable to packaged and split-system outdoor unit coils
  • Steps 1 and 2 are available to wholesale distributors in cases of four, one gallon containers and have shelf lives of two and three years, respectively
