How Heresite Excels in High-Humidity Environments

Humidity Gauge

Humidity is no friend to metal equipment. It works around the clock, settling into coils and slowly turning bare metal into rust.

For HVAC systems, constant moisture exposure is often the single biggest reason for equipment failure. That’s why Heresite develops coatings engineered to conquer corrosion in even the most demanding environments.

Battling High-Humidity and Corrosion

Humid air doesn’t just sit on a metal surface. It works its way into every seam and joint, creating an environment for corrosion to seep in. Left unprotected, coils in humid climates can begin to show surface oxidation within months of installation.

Our coatings are designed for condenser and evaporator coils in corrosive areas, protecting heat-transfer surfaces and boosting equipment life in high-humidity settings.

Rather than offering a single formula, we’ve developed a range of coating technologies, including air-cured, chemical-cured, baked epoxy, and phenolic systems, each focused on corrosion resistance and heat-transfer performance. Equipment on the coast and a landlocked rooftop unit face different levels of moisture, chemical exposure, and temperature. Having different coatings to choose from means having the right protection for real-life conditions.

Slower Structural Metal Breakdown

Once moisture reaches bare metal, oxidation begins, which leads to thinning of the metal, weakening of joints, and, over time, a compromise of the unit’s structural integrity. This is especially true for aluminum coils, where high humidity and coastal salt air speed up the breakdown of the metal.

Our approach is to create a physical barrier between your equipment’s metal and the environment. The coating fully covers the metal surface, acting as a guard that keeps corrosive elements from making direct contact and minimizes oxidation and corrosion that would compromise system efficiency and performance.

Many of these coatings are applied through a dip-and-bake immersion process, which coats every nook and cranny of a coil, not just the outward-facing surfaces most exposed to view, so the protection covers the parts of the equipment that are hardest to inspect and easiest to overlook.

Protecting Beyond the Standard

Our coatings have been evaluated in harsh marine and salt-air environments and resistance-tested against hundreds of chemicals. Testing has shown Heresite coatings deliver outstanding corrosion resistance in some of the harshest environments out there.

That performance carries over into chemically challenging settings. Our baked coatings are created to hold up across a wide range of highly acidic conditions. And that matters for facilities like fertilizer plants and wastewater treatment sites where humidity and chemicals combine to rev up corrosion beyond what a standard coating can handle.

We’ve Got You Covered

High-humidity environments quietly and ruthlessly punish equipment, which is exactly why they need a coating system engineered for the long run rather than a quick fix. Find out how our coatings give metal components a level of protection built to outlast the elements that would otherwise cut your equipment life short.
