Chemical Plant Within 1000 Feet Of Long
Island Sound + Co-Generation Power Plant (Natural Gas &
Fuel Oil) = Short Equipment Life
The continuous salt and petrochemical atmosphere, along with
acidic vapors and other corrosives, caused rapid deterioration
of equipment and the need to prematurely replace HVAC/R equipment
due to corrosion. New units with uncoated copper tube/aluminum
fin coils began showing discoloration and surface corrosion
immediately, and within 5-6 years would be totally deteriorated
with fins falling off. This was in spite of regularly scheduled
inspections, coil cleaning and equipment maintenance.
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.
