In order to better understand the quality of Safe Air Technology coating we have included a short video that provides detailed information about our coating practices. Additionally, you will find more information (below) that covers our coating procedures.
Click the video window located on the right side of this screen to learn more about the quality of Safe Air Technology Coating.
Should you have any questions, please call us. We look forward to hearing from you.
Will you coat equipment from other manufacturers or equipment that does not need explosion proofing?
Yes. Safe Air Technology offers coatings to all HVAC manufacturers. We have provided our coatings to Carrier, Trane, York, Rheem, and many other manufacturers. Safe Air Technology’s coatings have been proven in all types of corrosive atmospheres such as salt laden atmospheres, H2s gases, waste water treatment plants, paper mills, and many other environments around the world. Safe Air Technology has a proven track record not only in explosion proofing HVAC equipment, but also in protecting HVAC equipment from corrosive environments. Let our coating protect your equipment and add many years of reliable service to your systems.
How long does it take to get a HVAC system coated?
The time frame to coat equipment by Safe Air Technology’s coating department varies based on the correct coating and specifications for your project. Safe Air Technology has one of the largest coating departments in the industry with the ability to operate both day and night time shifts when required. Regardless of your specifications, Safe Air Technology can deliver your project with a level of quality and a delivery time that is superior to our competition.
Do you provide coatings for HVAC equipment for offshore platforms and refineries?
Yes. Safe Air Technology specializes not only in explosion
proof HVAC systems but also in the ability to provide a
coating for all types of HVAC equipment. This coating will
combat the corrosive atmosphere of an offshore platform such
as a salt laden atmosphere or H2s gas from a refinery, as
well as, many other types of corrosive atmospheres. Safe Air
Technology will work with you to provide the very best level
of protection for your equipment based on the project’s
environment.

Procedures for Coating with Heresite Air Dry Phenolic Protective Coating
- Unit to be disassembled of all metal parts.
- Gently straighten any bent or folded fins with appropriate FPI comb where needed.
-
Coils to be steamed cleaned with pressure washer to remove dirt, dust, oil, and all other contaminants to ensure non-interference with adhesion of coating. Steam water and coil is periodically tested to ensure appropriate temperature. Rinse from top to bottom and from all sides of the coils making sure fan tip pattern is aligned with coils. Rinse shall continue until rinse water does not exhibit any rainbows which are indicative of the presence of oil.
- Coils to be liberally flushed with a cleaner/degreaser providing a deep penetration for highly effective removal of oily residue and dirt on surfaces for a subsequent chemical coating. Cleaner/degreaser shall be mixed 1:3 with water allowing to soak on surface for approximately 2-3 minutes then liberally steamed cleaned.
-
Coils to be stored in a clean environment for a minimum of a 24 hour dry period, after which compressed air blown through ensuring coils are completely dry before application of Heresite Protective Coating.
-
All bare metal parts to be washed and scrubbed down with ZEP XT-4893 to remove dirt, dust, oil, and all other contaminants to ensure non-interference with adhesion of coating. ZEP XT-4893 is a pre-paint metal cleaner and phosphatizer that leaves ferrous metal surfaces with an iron phosphate coating that helps promote adhesion of coating to surface. All previously painted metal parts to be sanded to dull smooth, hard or glossy coatings to ensure adhesion. Sanded metal parts to be wiped down with tack cloth and cleaner to remove all dust and foreign material prior to coating.
-
Devilbiss spray gun shall be thoroughly cleaned and free of old paint film and other contaminants prior to application of Heresite Protective Coating. Dilution of Heresite VR-500 shall be to specifications of (4) parts coating to (1) part Heresite S-440 Solvent. Adjust air pressure for the gun to approximately 50 PSI. Apply first coat of Heresite VR-500 Series Air Dry Phenolic Coating. Allow 6-8 hours air dry time then apply second coat to ensure good film building and hard corrosion resistance.
-
All coating to be done in a controlled environment for a clean quality application. Quality Control/Quality Assurance to be performed on coils and all coated metal prior to re-assembly of unit.
-
Unit to be re-assembled with Stainless hardware.
- Unit to be tested upon completion of assembly.
Industrial Coating Solutions utilizes state of the art equipment and trained and certified personnel to ensure that all projects are prepped and coated in a quality manner that meets and exceeds our client’s expectations.
Benefits and Procedures for Coating with ADSIL MicroGuard Protective Coating
ADSIL MicroGuard HVAC Protective Coating is a clear surface performance treatment that chemically bonds to the surface of all metals therefore sealing out contaminants and corrosive gases. MicroGuard AD35’s patented protection technology works against acids, caustics, salts and UV providing numerous benefits including:
- Naturally repels moisture, chemicals, oils & dirt
- Will not support mold growth
- Enhances laminar airflow across fins of coils
- Effectively resist corrosion extending efficient operating life

Procedures for Coating with Macropoxy 646 Epoxy Products
Macropoxy 646 fast Cure Epoxy is recommended for a number of applications including the following:
- Refineries
- Chemical Plants
- Power Plants
- Pulp and Paper Mills
- Offshore Platforms
- Marine Applications
- Water treatment Plants
- Unit to be disassembled of all metal parts.
-
All Stainless Steel panels and surfaces to be cleaned with a non-hydrocarbon cleaner to remove dirt, dust, oil, and all other contaminants to ensure non-interference with adhesion of coating. All previously painted metal parts to be sanded to dull smooth, hard or glossy coatings to ensure adhesion. Sanded metal parts to be wiped down with tack cloth and cleaner to remove all dust and foreign material prior to coating.
-
All Stainless Steel panels and surfaces to be coated with DMT Wash Primer, a low VOC water based primer free of heavy metals and mineral acids, designed to be applied over Stainless Steel. Spray application shall be at 50 PSI with a dry film build of 0.7-1.3 mils (18-33 microns) allowing a minimum of two to three hour dry time before top coating. All previously painted metal parts to be coated with EPX-900, an epoxy primer that creates a superior corrosion resistant undercoating with excellent adhesion properties. This epoxy primer is a two part component system to be mixed at a 1:1 ratio with a “ready to spray” viscosity of 15-20 seconds #2 Zahn. Spray application shall be at 50 PSI with a dry film build of 1.0 – 2.0 mils (25-50 microns) allowing a minimum of one hour dry time before top coating.
-
All Stainless Steel and previous painted metal parts to be coated with Macropoxy 646, a high solids, high build polyamide epoxy designed for industrial exposures. This epoxy is a two part component system to be mixed at a 1:1 ratio, reduced as needed only after both components are thoroughly mixed and allowed to sweat-in. Spray application shall be at 60-80 PSI with a dry film build of 7.0 – 10.0 mils (250-300 microns) allowing a minimum of eight hour dry time before recoating (if necessary) and handling.
-
Quality Control/Quality Assurance to be performed on all coated metal prior to re-assembly of unit. Unit to be re-assembled with Stainless hardware.
-
Unit to be tested upon completion of assembly.
-
All coating to be done in a controlled environment for clean quality application and quality checked upon completion of coating.
