Radiator and Cooling Panel Coating for Indiana Transformer Plants
Transformer radiators are made of closely spaced fins and panels that are hard to coat evenly by spray alone. Coverage between fins, drainage of excess coating and cure all need attention. Indiana transformer plants coating radiators need equipment arranged for those challenges. Booths, drain-off areas, ovens and the air connections behind radiator finishing are all part of what Double D Mechanical installs and maintains.
Discuss your installationGetting Coating Between the Fins
Radiator fins are narrow and close together. Spray can miss inner surfaces, so many plants use flow coating or dip methods followed by drain-off. Others use spray with careful technique. The method drives equipment layout.
Drain-Off and Drip Control
After flow coating or dipping, excess coating drains from the radiator. A drain-off area with sloped floors, collection trays and ventilation keeps excess coating contained and solvent vapor controlled.
- Contain drips with trays or sloped floors
- Ventilate drain-off areas
- Keep drain-off near the cure oven
Cure Ovens for Radiators
Radiators are long and thin but numerous. An oven that holds several radiators at once, with airflow that passes between fins, gives even cure.
Solvent Vapor and Plant Balance
Coating and drain-off areas release solvent vapor, so each needs proper exhaust. Make-up air replaces exhausted air and keeps the plant balanced.
Planning a booth or oven project in Indiana
Crews mobilize from Houston; Indiana is roughly 850 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.
Manufacturing in Indiana is concentrated around Indianapolis, Fort Wayne, Evansville, and South Bend. The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include automotive and powertrain, RV and trailer manufacturing, steel, and aerospace components.
Cold winters mean make-up air heaters are sized for sub-freezing intake, and booth or oven placement has to account for frost lines, snow loads on roof penetrations and winter slab work.
Frequently asked questions
Is flow coating better than spray for radiators?
Flow coating often gives better coverage between fins. Spray is used when the coating system and radiator design allow.
Do drain-off areas need ventilation?
Yes. Solvent vapor from draining coating must be exhausted.
Can radiators share an oven with tanks?
Sometimes, if the oven is large enough and cure schedules match.
