Air Make Up Units for Pipe Spool Coating
Pipe spool booths and blast support areas can exhaust a significant amount of air while production still needs stable spray conditions. Double D Mechanical installs, relocates and services air make up units for spool coating operations where exhaust balance, heat and controls affect booth performance.
Discuss your installationReplacement Air for Booth Demand
Exhaust fans remove air from spray and prep areas, and that air has to be replaced in a controlled way. The make up air unit should be reviewed with booth exhaust volume, building pressure and nearby openings.
Discharge Location Near Spool Work
Air introduced too close to the spray face can disturb coating on curved pipe surfaces or push overspray into aisles. Discharge placement should support booth capture while leaving crane paths, doors and service platforms clear.
Heat, Utilities and Controls
Heated air, electrical service, gas piping, controls and interlocks all need coordination with booth operation. Control sequences should reflect how the plant starts exhaust, spray equipment and occupied work zones.
Roof and Service Space Review
Unit placement may involve roof curbs, wall openings, duct supports and maintenance clearances. Existing structure, access routes and weather exposure should be reviewed before equipment selection and layout are finalized.
Frequently asked questions
Why is replacement air important for pipe spool booths?
Without planned replacement air, exhaust can pull from doors or adjacent areas and create drafts that affect coating quality and containment.
Can one unit serve more than one booth area?
That depends on airflow needs, control zoning, duct routing and whether the operating modes can be coordinated.
What site details help with review?
Booth exhaust data, building layout, roof structure, gas and electrical locations, and preferred unit placement are useful starting points.
How does make up air affect operator comfort?
Tempered replacement air can help reduce drafts and temperature swings around the coating area when it is introduced correctly.
