Belco manufactures two styles of shrink tunnels to complement every level of shrink film sealer available to our industry. These tunnels will handle all commercially available shrink films, including polyethylene. From production speeds of five up to 150 packages per minute, there is a Belco tunnel suitable for your application.

We introduce the product line with our fan style tunnels, which are Models ST 1808, ST 2108 and the ST 3010. These models are rated for production speeds of 5-25 packages per minute or 500,000 to 2,600,000 packages per year. (Based upon one 8-hour shift).

The tunnel temperature is regulated by a Watlow 988 microprocessor based controller. The hot air is directed about the shrink chamber by use of fan blade wheels, which are placed within the footprint of the square shaped heater elements. The hot air "washes" or "scrubs" the shrink film surrounding your product to quietly balloon the film and then tightly shrink to the contours of the package.

Chamber sizes range from 18" Wide x 8" High x 24" Long for the ST 1808 to 21" Wide x *" High x 36" Long for the ST 2108 and 30" Wide x 10" High x 48" Long for the ST 3010.
Optional extended heights are available for taller packages.

Whenever the package dimension comes within 2" of any chamber wall, seek factory advice. The concern is the shrink film contacting the chamber surface during the ballooning process. Typically, the next size shrink chamber will be recommended, but not without careful evaluation.

All tunnels are available with conveyor choices of Teflon mesh belt, silicone rubber sleeved live rod/rollers or Falcon belt style conveyors.

The rule of thumb is Teflon mesh belts handle light products up to five pounds, the rod conveyor is for heavier products up to 25 pounds, as well as applications where aesthetics are critical and the Falcon belt is for your heaviest packages and shrink polyethylene films.

Option are available to best meet the demands of your application such as Lighted Viewing Window (except ST 1808), specific voltages and extended infeed or exit conveyor lengths. All tunnels are available with stainless steel construction for typical food plant wipe-down environments.
