The company had used baked phenolic coating in the past, but it flaked off with age. Also, they could not do effective repairs of the damaged baked phenolic coating in the field.

1n 1993-1994, the company built a new office/shop/maintenance building requiring six new AC units installed. All six were Trane All Comfort AC units from 10-30 tons.

The Project Engineer on staff did some research to find a superior coating for the new units, one that met their criteria and was within the allocated costs for the project. After researching their options, the Project Engineer, along with the company's HVAC Master Technician, recommended Bronz-Glow.

The company continues to perform the same scheduled maintenance as before, including complete quarterly operational tests and inspections. They use the high-surfactant Bronz-Glow Husky Coil Guard Cleaner.

To date they have seen no deterioration on the coils over a 10-year period.

Their HVAC Master Technician adds, "We've never had to do any touchup on the coils since they were installed. We even had a big hailstorm a few years ago that bent the fins on the condenser coils, but none of the Bronz-Glow came off. In my experience, a more rigid coating such as the baked phenolics we had used in the past, would probably not have withstood this without chipping or cracking. I have been surprised at how well Bronz-Glow has performed here. For our units to have lasted ten years in this environment is incredible... and they're still running strong."

"As recently as 2002 we replaced another unit that had deteriorated at the co-gen plant. We Bronz-Glow coated the replacement. Within next couple of years we will probably be replacing several additional units, and I will be recommending Bronz-Glow for all new units, and I would recommend Bronz-Glow for anybody in a corrosive environment such as ours. Bronz-Glow is definitely worth the money... it works.
