Large Commercial HVAC Cabinet Finishing in Michigan
Commercial rooftop units and air handlers are big. Their base rails, cabinet sections and panels can be far larger than residential parts, and some are coated as welded assemblies. Michigan HVAC manufacturers building commercial equipment, including around Detroit, need lines that handle size and weight. Double D Mechanical handles installation, relocation and service of the booths, ovens and air systems that support large-cabinet finishing.
Discuss your installationPower-and-Free for Big Parts
Large parts benefit from power-and-free conveyors that let carriers stop in booths and ovens. Longer dwell times at application and cure stations help with heavy steel.
Booths Sized for Assemblies
Welded base rails and cabinet frames need large booth openings and room to coat all sides. Some plants use walk-in booths for large assemblies alongside conveyor lines for panels.
Ovens for Heavy Steel
Heavy base rails take time to reach cure temperature. Burner capacity and dwell time must match.
- Check cure on base rails specifically
- Plan oven openings for the largest assembly
- Consider separate walk-in ovens for oversize parts
Planning Ahead
Part sizes, weights, production volumes and building information help shape the line design.
Planning a booth or oven project in Michigan
Crews mobilize from Houston; Michigan is roughly 1,100 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.
Manufacturing in Michigan is concentrated around Detroit, Grand Rapids, Lansing, and Flint. The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include automotive assembly and suppliers, office furniture, tool and die, and EV batteries.
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
Can large assemblies run on the same line as panels?
Sometimes, with power-and-free conveyors and large booth openings. Others use separate walk-in equipment.
Are walk-in booths worth it for oversize parts?
They keep large parts from slowing the main line.
How do you cure heavy base rails?
With enough burner capacity, airflow and dwell time to heat the steel fully.
Can you relocate a large line?
Yes, with careful planning, documentation and recommissioning.
