Rohner for HVAC Units and Fans
HVAC unit and fan finishing often involves sheet metal panels, cabinets, frames, fan housings and guards moving through coating before assembly. Rohner equipment for this type of production can include open-face booths, powder coating booths, powder coating lines, cure ovens, make-up air and exhaust systems. Double D Mechanical installs, relocates and services the booth, oven, air, exhaust and utility connections that support those finishing cells.

Cabinet Panels And Rack Flow
HVAC parts range from flat panels to deep housings and assembled frames. The finishing layout should account for rack spacing, part orientation, operator reach and the path from fabrication or wash to coating and cure. Door openings and oven loading should fit the racks, not just the parts.
Powder And Liquid Area Choices
Some HVAC components move through powder coating, while others may use liquid paint depending on part requirements and production flow. Booths, ovens, paint mixing rooms and staging should be arranged so clean parts do not cross raw sheet metal traffic or rework areas.
Air Balance Near Assembly
Finishing areas located near assembly lines need careful exhaust and make-up air coordination. Replacement air, fan discharge, oven heat, compressed air and electrical service should be reviewed together so coating equipment does not create drafts or temperature swings in nearby work areas.
Service Paths For Repeated Production
Filters, lights, powder recovery components, oven doors, burners, fans and control panels need reachable access during regular production. Relocation and service work should preserve rack movement while allowing maintenance teams to reach the equipment without dismantling surrounding line features.
Frequently asked questions
What should HVAC manufacturers prepare before a site visit?
Prepare part sizes, rack dimensions, coating type, process order, oven loading method, utility locations and any assembly lines or aisles that must stay open.
Can HVAC panels and fan housings share one finishing line?
They can if rack design, part spacing, cure needs and handling methods work together. Larger housings may need different clearances than flat panels.
Why does make-up air matter near assembly?
Booth exhaust can pull conditioned air from adjacent areas. Make-up air helps reduce pressure changes, drafts and temperature swings around nearby workers.
What utilities are usually involved?
Electrical service, compressed air, control wiring, exhaust ductwork, make-up air and gas or electrical heat for ovens should be reviewed.
What service access should be preserved?
Keep room for filter changes, fan service, light access, oven door work, burner checks, powder recovery cleaning and control panel access.
