These high speed recirculating air tunnels are designed for speeds in excess of 50 packages per minute or where the application calls for absolute shrink quality, seal placement, speed and aesthetics. Two independent microprocessor based Watlow digital temperature controllers monitor the infeed tunnel chamber separate from the exit shrink chamber. Infeed and exit air flow controls allow you to adjust air flow in each chamber as required.
This allows you to run production speeds with the least amount of heat required as you direct the hot air flow exactly where it is required to produce the best shrink packages possible, regardless how difficult the shape. Automatic cool down and shut off is standard.
