Rapid Engineering air make-up units for storage tanks and pressure vessels
Storage tanks and pressure vessels bring large shells, domed heads, saddles, nozzles and weld seams into the finishing area. Rapid Engineering air make-up units are part of the mechanical planning for blast rooms, large paint booths and exhaust systems that need steady replacement air while operators coat heavy fabricated parts.

Shell Size And Booth Fit
Tank and vessel work needs clear movement paths for cranes, rotators, carts or rail-guided fixtures before the booth or blast room location is fixed. The layout should account for shell diameter, nozzle projections, manway covers and the room needed to coat around saddles without forcing operators into poor spray positions.
- Confirm the longest shell and largest diameter expected in the space.
- Identify lift points, turning methods and door swing clearances.
- Keep access around heads, seams and supports open for coating inspection.
Replacement Air For Large Exhaust Loads
A large booth or blast enclosure can remove a significant volume of plant air. Rapid Engineering air make-up equipment must be coordinated with booth exhaust so the room does not pull air from welding, assembly, warehouse doors or adjacent finishing steps. Balanced airflow helps maintain capture at the booth face and keeps overspray or dust from drifting into nearby work areas.
Utilities And Structural Coordination
Before installation or relocation, the mechanical plan should locate gas, power, controls, duct routing, roof openings and service platforms. Heavy tank finishing often shares space with cranes and high-bay structures, so duct and heater placement must avoid hook travel, building steel and maintenance paths.
- Mark roof penetrations and structural conflicts early.
- Confirm gas pressure, electrical capacity and control locations.
- Coordinate fire protection, lighting and interlocks with the booth package.
Maintenance Access Around Air Units
Make-up air equipment needs room for filters, belts, motors, burners, dampers and control panels. On tank and pressure vessel lines, maintenance access should remain reachable even when a large shell is staged in front of the booth, because clogged filters or heater issues can affect coating quality and production flow.
Site Visit Readiness
A useful site review starts with drawings, equipment data and a clear view of how vessels move through prep, coating and cure or dry-off. Double D Mechanical can review the installation path, air and exhaust connections, utility routing and trade sequencing when those details are available.
- Current booth, blast room and air unit drawings if available.
- Part envelope, weight range and handling method.
- Photos of roof, walls, utilities and nearby process equipment.
Frequently asked questions
Where does the air make-up unit fit in a tank finishing layout?
It is typically planned with the booth or blast room exhaust so replacement air enters without disrupting spray patterns, dust capture or operator work zones.
What makes pressure vessel finishing different from smaller fabricated parts?
Shell diameter, nozzle projections, weld seams and handling equipment usually drive larger clearances, longer doors and more careful exhaust and replacement air planning.
Can an existing booth be evaluated for larger vessels?
Yes. The review should compare the part envelope, door opening, exhaust capacity, make-up air, utilities and maintenance access against the new work mix.
What should be ready before discussing relocation?
Have the equipment drawings, current utility connections, roof or wall penetration details, rigging constraints and the intended production sequence.
Why coordinate make-up air with blast equipment?
Blast rooms and media recovery systems can affect building pressure and dust control, so replacement air planning should be considered with the full prep-to-paint flow.
