INDUSTRY FAQs
Frequently Asked Questions
Why does paper machine dryer hood exhaust require aluminum or stainless ductwork?
Exhaust air from paper drying carries near 100% relative humidity at 80°C, which rapidly rusts standard galvanized iron ducting.
How does humidity control prevent paper roll curling?
Paper fibers expand when absorbing ambient moisture; maintaining stable relative humidity keeps moisture content uniform across the sheet.
