Protective Coating Booths for HVAC Coils in Kentucky
Finned heat exchanger coils are often coated to resist corrosion, especially for units headed to harsh environments. Coating coils is different from coating sheet metal: the coating must penetrate between closely spaced fins without bridging them. Kentucky HVAC manufacturers applying these coatings need booths and air systems built for that work. Double D Mechanical installs, relocates and services coil coating booths together with their exhaust and utility connections.

Coil coatings are typically applied by spray or dip, with techniques that drive coating through the fin pack. Booth size and layout must allow coating from both faces of the coil.
Drainage and Excess Coating
After application, excess coating drains from the coil. Drain areas with collection trays and ventilation keep the process clean and control vapor.
Curing Coated Coils
Some coil coatings air-dry, while others need heat. Cure space should allow airflow through the fins for even drying.
- Allow air to pass through the coil
- Follow coating maker's cure schedule
- Keep coils separated during cure
Venting the Coil Coating Area
Coil coating releases solvent vapor, so booths and drain areas need proper exhaust and make-up air.
Planning a booth or oven project in Kentucky
Crews mobilize from Houston; Kentucky is roughly 800 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.
Manufacturing in Kentucky is concentrated around Louisville, Lexington, Bowling Green, and Northern Kentucky. The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include automotive assembly, aerospace components, appliances, and EV batteries.
Hot, humid summers and mild winters put the emphasis on make-up air cooling or tempering, filter change schedules and keeping intake away from loading doors.
Frequently asked questions
How is coating applied to coil fins?
Usually by spray or dip, using methods that drive coating into the fin pack.
Do coated coils need ovens?
Some coatings air-dry, others need heat. The coating maker specifies the cure.
Can coil coating share a booth with cabinet painting?
It is usually better to separate them because coil coatings and methods differ.
Do you install drain areas and exhaust?
Yes. Booths, drain areas, exhaust and make-up air are installed and connected.
