Industrial Plants

APPLICATION NOTES

What the buyer should prepare.

Plant ventilation fails quietly. An undersized fan cannot overcome real duct resistance; dampers seize in fume-laden air; ducts corrode from process gases. The cost appears later as heat stress, failed inspections and early replacement.

What the environment demands

• Heat and fume extraction at the source, before it spreads across the shop floor.
• Make-up air balanced so doors stay operable and negative pressure does not build.
• Fire and smoke zoning that respects compartment walls and high-bay volumes.
• Materials matched to the fume composition, including stainless options where corrosion is real.

Typical equipment package

• Industrial centrifugal fans and roof exhaust fans for process extraction.
• Stainless steel fans, dampers and ducts for corrosive or humid fumes.
• Fire dampers and smoke exhaust fire dampers at compartment boundaries.
• Galvanized ducts and silencers for general ventilation and offices.
• Fresh air handling units for workshops with occupied stations.

Selection points to confirm before ordering

• The actual operating point on the fan curve, including filter and duct loading over time.
• Material selection against fume composition, temperature and humidity.
• Damper positions and access in high-bay spaces where service is difficult.
• Reserve capacity in main ducts for planned production expansion.

How JINLONGSEN supports this application

Describe the process — heat sources, fume type, working hours — and our engineering team returns fan selections and a duct concept instead of a catalog page. Stainless product lines are produced in-house, packages ship against project milestones, and OEM production is available for equipment integrators.
