HVAC Coil Painting System

Some clearcoating solutions (adv.)    g j nikolas banner   everbrite banner

Does anyone have any information on HCAC coil painting, to protect evaporator and condenser coils ( which consist of aluminum fins and copper tube ).We have been facing problems when we install our AC plant in sewage treatment plant; it starts leaking from the copper tube and all aluminum fins are damaged.

Your problem is that the environment the coils are being put into is corrosive. Try locating the compressor units outside the corrosive area, maybe inside some kind of enclosure. Coating those coils with anything very substantial will ruin their efficiency. Maybe you could shield them with some kind of filter to keep the chemical vapors away.

That's about all my ideas... try contacting the manufacturer for some more enlightened information.

What we do in extreme weather conditions is use Copper tube / Copper fin evaporators and condensers. In conjuction with Copper/copper we will use a Herisite epoxy and spray on the coils also. Once we spray, we bake the epoxy on to the coils.

I have experienced the Onsite coat of Aeris Environmental to be extremely good for the coating of air cooled condensers and the AHU coils against environmental and galvanic reactions.

Hi, folks. No more brand recommendations please :-)

We appreciate your efforts to help, but this free site is for camaraderie and technical discussions, and is possible only because of our supporting advertisers. If we ask them to pay the costs of posting testimonial to their competitors, how can they not say "finishing.com is a nice idea but we can't afford to pay for a forum where our competitors pay nothing, yet the readers are steered to buy from them instead of us :-)"

Please try to recommend generic types of coatings, not brands. Thanks!

No need to use copper it is too expensive. Use a silane based coating (glass) and you will extend the efficient operating life by a factor of 2. However, that is the limit.
