Re-circulating Air Tunnels
Customers use this style tunnel where the application calls for absolute shrink
quality, seal control, speed or aesthetics. This series of machines is available in
many chamber sizes and uses fin-strip heating elements in combination with a
forced air flow design. Its micro-processor based temperature controls maintain
precise tunnel temperature and the air delivery pattern allows for the precise
application of hot air directly to the film as the package is conveyed through the
shrink chamber. You have the ability to pattern the air flow, allowing it to contact
the film wherever you select, in order to get the best shrink results for difficult
shapes. Automatic cool down and shut off is standard on these machines.
