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