Inert dryers require that a web be dried and/or cured with hot “air” that contains no or very little oxygen. The web entrance and exit slots, as well as all doors must be air tight to preserve the integrity of the internal atmosphere of the dryer. In some cases, the dryers will also incorporate solvent recovery systems.
Air Tight Enclosures
This inert dryer is manufacturing magnetic tapes. The mechanism at the web slot is a “nitrogen seal” that prevents outside air from entering the dryer as the web exits. Knife-edge seals on the doors are air tight.
Custom Web Paths
This steam-heated dryer is unique because of the orientation of web as it passes through the box. Note that the web enters and exits on the right side of the dryer through nitrogen-sealed web slots.
This three zone inert dryer includes an integrated solvent recovery system. The top-side coating is dried with slot nozzles as the web is transported through the dryer on idler rolls.
