Condensed Report: Capacity Tests on Bronz-Glow Coated Coils

These tests were conducted to determine the cost-effectiveness and energy efficiency of condenser coils coated with Bronz-Glow Coil Coatings, for protection against atmospheric corrosion in temperate marine environments (salt air). Several commercial “coatings” were tested for corrosion resistance, as well as their effect unit capacity (heat transfer efficiency)

In each test, the coil, the brace, capacitor bracket, capacitor, divider wall, and reversing valve were coated, then placed in salt spray along with an untreated component. The salt spray test was performed in accordance with ASTM B117.85 standards, using a 5.0% salt solution at 96.0° F., with 100% humidity. The components were exposed for 240 hours, removed and rinsed with cool water, and the process repeated to a total of 1200 hours.

Bronz-Glow Coil Coating was included in the series of tests. “For coil protection the Bronz-Glow Coil Coating proved to be the best (of the various coatings tested). There is no evidence of failure (fin deterioration).”

“The untreated coil had fin deterioration around the header plate (after the same exposure).”

Bronz-Glow coil coating is a complex, chain-link Polyelastomer process, resistant against the entire pH scale of corrosives.

Complete capacity tests were performed on each unit before and after the Bronz-Glow coating was applied.

Chassis was tested before and after treatment. Tests indicate no change in unit performance.

The primary performance data was as follows:
