Air Make Up Units for Ship Block Finishing
Finishing ship blocks and hull sections can move a large amount of air through booths, blast areas and exhaust systems. Double D Mechanical installs, relocates and services air make up units and the duct, control and utility connections that help replace exhausted air in marine fabrication finishing areas.
Discuss your installationReplacement Air for Large Work Zones
Paint booths and preparation areas for marine sections can place heavy demand on building air balance. Air make up planning should consider exhaust volume, booth operating modes, door openings and how replacement air enters the work zone.
Discharge Location and Draft Control
Large hull sections can create uneven air paths around curved plate, stiffeners and interior openings. Supply discharge should be coordinated so air supports booth performance without creating drafts that disturb spray patterns or worker comfort.
Heat, Fuel and Electrical Needs
Tempered air can support coating conditions and plant comfort during finishing work. Unit selection and placement should be coordinated with available fuel, electrical service, roof structure, combustion air needs and access to controls.
Duct Routes Through Busy Buildings
Marine fabrication buildings often include cranes, high doors, structural steel and other large equipment. Duct routing should protect crane travel, maintain service reach and align with wall or roof penetrations that the building can support.
Information for Air Balance Review
A practical review starts with the systems that exhaust air and the spaces that need replacement air.
- Booth and exhaust equipment information
- Largest door openings and operating patterns
- Preferred unit location or available roof area
- Fuel, electrical and control connection points
Frequently asked questions
Why is make up air important for ship block coating?
Large exhaust systems remove significant air from the building, and replacement air helps maintain booth performance, pressure balance and workable conditions.
Where can an air make up unit be located?
Location depends on roof or grade space, structural support, duct route, utility access, service clearance and the best discharge point for the finishing area.
Does make up air connect to booth controls?
Controls are commonly coordinated so the air make up unit operates with exhaust and booth modes, subject to the equipment and project requirements.
What should be gathered before the walkthrough?
Collect exhaust equipment data, booth layout, building drawings if available, utility locations and photos of possible unit and duct routes.
