Rohner for Transformer Tanks
Transformer tanks and covers can combine heavy weldments, gasket surfaces, flanges, lifting lugs and interior recesses that need controlled preparation and coating access. Rohner large equipment booths, blast rooms, powder booths and cure ovens may be supported by make-up air, exhaust and utility systems. Double D Mechanical installs, relocates and services the booth, oven, air, exhaust, lighting and utility connections for this work.

Tank Envelope And Lift Clearance
The layout should be checked around the largest tank, cover and support fixture, including lifting lugs, bushings, flange projections and handling equipment. Booth doors, crane approach, forklift aisles and operator platforms need enough room for coating access without blocking the entry path.
Preparation To Coating Handoff
Transformer tanks may move from blast or surface preparation into primer, topcoat or powder depending on the process. Dust containment, clean staging and masking areas should be placed so gasket faces and openings stay protected before coating. Media reclaim equipment and blast room service access should be part of the same layout review.
Oven Loads And Air Systems
Heavy steel mass, cure requirements and booth exhaust volumes can place meaningful demands on heat, make-up air and electrical service. Duct routes, exhaust stacks, gas piping, control wiring and roof access should be coordinated before equipment is set.
- Record tank, cover, fixture and handling equipment dimensions.
- Identify blast, mask, coat, cure, cool-down and inspection zones.
- Confirm utility capacities, roof access and overhead obstructions.
Maintainable Large Equipment
Fans, burners, filters, lights, doors, duct cleanouts and controls need access after tanks and fixtures are in normal production positions. When relocating equipment, review panel condition, oven condition, fan assemblies and available rigging paths before final sequencing.
Frequently asked questions
What dimensions are important for transformer tank finishing?
Tank length, width, height, cover size, lifting lugs, flange projections, fixtures and the handling path into the booth all matter.
How should blast and paint areas be arranged?
They should allow cleaned tanks to move into coating with limited handling while keeping dust away from masked and finished surfaces.
Why review oven loading early?
Tank mass, fixture size, heat connections, exhaust and cool-down space can all affect where the oven and surrounding utilities fit.
Can Rohner transformer tank equipment be relocated?
Relocation depends on equipment condition, section sizes, removal path, rigging access, utility routes and the new bay layout.
What should a facility gather before a site visit?
Gather tank drawings, fixture details, process flow, utility locations, roof access information and photos of existing booths or ovens.
