Q. Do the coating(s) attract dirt
more than a non-coated coil?
A. Generally attraction of dirt is about equal between a coated
and non-coated coil. The adhesion of dirt to the coil differs
between a coated and non-coated coil. The coated coil has
a slicker surface than a non-coated coil. The dirt tends to
cling to the rougher or less slick surface. Bronz-Glow introduces
a final spray-on dress coat (Dress Coat) that help with the
free flow of the dirt and soils from the fin surface with
the introduction of moisture (rain or water spray
Q. What effect does the coating
of an evaporator coil have in regards to condensation removal?
A. Through factory, field and laboratory testing there have
not been any negative results with regard to moisture carryover,
moisture removal or condensation. Bronz-Glow coatings do have
the effect of allowing free flowing and less susceptible to
being carried back into the air stream or ducting.
Q. How is the best way to clean
a coated coil?
A. When dealing with Bronz-Glow coated coils we offer
our clients a booklet titled “Owner’s Coated Coil
Cleaning & Maintenance Service Manual.” This booklet
was written to reinforce the need to routinely clean coated
or un-coated coils to assist in maintaining optimum operating
efficiency. We like to say, “A clean coated coil is
a happy and efficient coil!”
Q.Will any coil cleaner work or
are there coil cleaners I should avoid?
A. There are many cleaners on the market. Some are
very good and safe, while others are quite caustic and can
cause more harm than good.
Bronz-Glow recommends you use only biodegradable and environmentally
safe surfactant system cleaners. These are cleaners that do
not attack the coating or fin alloy. They are free rinsing,
safe and more pleasant for the technician to use.
These cleaners will not foam as much as harsh base or acidic
cleaners because they are not attacking the good metal of
the fin. The foam generated by most cleaners is because it
is reacting with the good metal or alloy of the fin, thus
removing a layer of good metal from the coil. We recommend
against the use of harsh cleaners. All of our cleaners meet
these two criteria, and utilize a surfactant system that helps
to pull and draw off dirt and contaminants from your coils
(whether coated or not).

Q.Do coated coils require more frequent
cleaning than non-coated coils?
A. Equal cleaning is required to both coated and
uncoated coils. Dirt and airborne particulate attach to
the
coil and need to be washed of on a regular basis to maintain
optimum operating efficiency. Power utility companies are
strong advocates of regular coil
cleaning and coil coatings to reduce unnecessary energy consumption
through inefficient exchange of air-cooled coils. Equipment
manufacturer and energy experts agree that ALL coils should
be cleaned 2-3 times each year. Even though a coil is coated,
dirt and debris can still cause a coil not to operate efficiently.
Many utilities, such as the Jacksonville Electric Authority,
have hints for homeowners on their websites. The JEA offers
a free booklet called “Power for Pennies,” where
they recommend coil cleaning as well as coil coating to
protect
fin tube coils and keep them energy efficient.
Q.If an A/C system should develop
a leak, will the oil that leaks onto the coated surface hurt
or destroy the coatings?
A. Yes, refrigerant oils and blends of Freon are petroleum-based
products and may damage the coating in the vicinity of the
leak. Should a freon leak occur for any reason, it could have
a softening effect on any coatings in the vicinity of the
leak, including Bronz-Glow.
With Bronz-Glow coil coatings we offer an aerosol touch-up
kit which includes the coil coating. Once the leak is repaired
you can touch-up the area where damage to the coating took
place from the leak or during the repair of the leak.
Q. If someone or something damages
the coating, is there a repair kit available?
A. Yes. Our coatings are available in aerosol cans and even
complete coating kits. Simply spraying the affected areas
will repair the Bronz-Glow coil coating.
Q. How is repairing or recoating
with Bronz-Glow different from other coatings?
A. Bronz-Glow’s unique chemical makeup allows
the new coating to blend in and bond to the existing coating.
Unlike almost every other protective coating on the market,
Bronz-Glow doesn’t just “patch” the damaged
area. When a coating is “patched,” a seam is left
which offers an opportunity for new corrosion. Bronz-Glow
aerosol spray repair coating actually “melds”
to the existing Bronz-Glow coating, creating an unbroken repair
with no seams.
Also, Bronz-Glow's coatings are "one-part" coatings,
so every time the coating is applied, it is the same. With
two-part coatings, every time a new batch is mixed in the
field, it is chemically different that the previous batch.
This also eliminates the problem of wasting the unused coating.
Finally, baked coatings, such as phenolics, are extremely
difficult to repair once damaged. Because the original coating
was baked on the surface, any repair in the field is truly
a "patch."
Q.. Does Bronz-Glow Factory Field
Services provide a/c maintenance programs?
A. Yes. Bronz-Glow Factory Field maintenance programs
consist of coil cleaning, filter changes and touch-up of any
damaged or scratched coating. Bronz-Glow does not service
the heating, refrigeration components or gas side of the unit.
Q. Can Bronz-Glow keep my AC unit
in top shape to insure extended life?
A. Yes. Bronz-Glow offers a maintenance program consisting
of a 1, 2, or 3 times a year cleaning service. This includes
washing the coil and cabinet with Bronz-Glow’s Husky
Coil Guard (Biodegradable Surfactant Cleaner) or Husky Coil
Sheen (Mineral Acid Coil Cleaner). Your coil surface is fully
inspected for any damage, and recoating of the affected area
is included at no extra cost to you.
