Air Make-Up Units for LNG and Energy Modules
LNG and energy module fabrication can involve large frames, pipe spools, equipment skids and coated assemblies moving through demanding ventilation areas. Double D Mechanical installs, relocates and services air make-up units that support paint, blast and cure equipment with coordinated airflow, ductwork, utilities and service access.
Discuss your installationReplacement Air for Module Coating Work
Module finishing spaces may exhaust significant air while handling large steel assemblies and coated components. Make-up air should be introduced so it supports the process without creating cross drafts or pulling shop air from welding, grinding or staging zones into coating areas.
Routing Near Skids and Pipe Spools
Duct routes need to account for tall modules, crane lifts, pipe racks, floor openings, cable tray and overhead utilities. Equipment placement should leave room for rigging, filter changes, fan service and clear movement of large assemblies through the finish area.
Connections With Exhaust Operation
Air make-up units should be coordinated with exhaust fans, booth controls and heating requirements. Power, fuel, control wiring and dampers need a clear sequence with electrical and building trades before commissioning activities begin.
Pre-Visit Information to Assemble
Bring available drawings, airflow data, module size ranges, crane and rigging constraints, utility locations and photos of proposed indoor and outdoor equipment areas. If the unit is being moved, include current duct routes and known operating issues.
Frequently asked questions
Why is make-up air planning important for LNG module coating?
Large exhaust systems can change building pressure and airflow direction, which can affect coating conditions and adjacent fabrication spaces.
What clearances should be protected?
Protect paths for modules, pipe spools, cranes, lifts and service work at filters, fans, dampers, heat sections and controls.
Can make-up air be added to an existing coating area?
Yes, the existing exhaust, structure, utilities, duct paths and available service space should be reviewed before selecting an approach.
What should facility engineers gather first?
Gather equipment drawings, exhaust data, roof or wall conditions, utility information, control requirements and photos of likely routing obstacles.
