ADVANCED PROTECTION FOR HVAC COILS
CoilSafe Plus®
For even greater IAQ protection, CoilSafe Plus® includes an added silver ion antimicrobial agent, making it ideal for evaporator coils in high-moisture or high-traffic environments. It actively combats microbial buildup on coil surfaces while delivering the same thin-film efficiency gains as standard CoilSafe®.

Defend Against Corrosion, Fouling & Microbial Growth
CoilSafe Plus® is a high-performance antimicrobial coating designed specifically for evaporator coils. It not only prevents corrosion and fouling but also incorporates an advanced silver ion additive that actively protects against the growth of mold, bacteria, mildew, and even viruses, including SARS-CoV-2.

Thin, Tough & Efficient
At just 8-10 microns, CoilSafe Plus® goes on thin, so it won’t reduce heat transfer or impede efficiency. This glass-like inorganic coating repels dirt, oil, and moisture, and forms a covalent bond with the coil surface for long-term durability, even in harsh environments like coastal or industrial areas.
- 50% harder than epoxy for enhanced durability, yet flexible enough to expand and contract with your equipment.
- Zero efficiency loss—CoilSafe Plus® maintains the unit’s heat exchange performance.
- Restores units to 90–95% efficiency by reconnecting the fin shoulder to the tubing and improving airflow.
Proven Antimicrobial Power
- Passed ASTM G21 fungal testing – zero growth
- ISO 22196 – effective against bacteria
- ISO 21702:2019 – tested against viruses
- UVC durability – Passed 900+ hours with no degradation
Built For Harsh Conditions
- Survives 6,000+ hours in ASTM B117 salt fog and G85 acidified environments
- Rated to withstand heat up to 1,800°F
- Resilient in high-humidity, UVC-rich environments where most coatings fail
Easy Application, Immediate Impact
CoilSafe Plus® can be applied in the field or at our coating center, whether your equipment is new or already in service. It’s low-VOC, quick to cure, and ideal for rooftop or coastal installations where protection matters most.
CoilSafe Plus® Testing
ANSI/UL 723 Flame & Smoke Spread
Flame Rating of 0, Smoke Rating of 0
This test used CoilSafe Plus® applied to a cement board and then subjected to a metered flame at specified temperature and duration. With flame rating of 0 and smoke rating of 0, CoilSafe Plus® is a tier 1 material and highly resistant to flame or heat.
ISO 22196 Bacterial Growth Test
99.5% Reduction in Bacteria
This test used a measured number of designated bacteria’s and measured the kill rate over a 24-hour period.
ISO 21702:2019 Viral Growth Test
99.8% Reduction in COVID SARS2
This test used a measured number of Covid SARS 2 virus and measured the kill rate over a 24-hour period.
UVC Light Ray Exposure
900 Hrs. Passed With No Change
CoilSafe Plus® was exposed to UVC, and pencil harness and adhesion tested every 200 Hours, with no change in the performance noted.
