Main Power Switch
Turns on/off the power to the entire machine. Maintains all previously
set tunnel adjustments, which assures rapid start up and consistent
quality at the beginning of your next shift.
This switch allows the heaters to be shut off at the end of your
production run without having to change temperature settings. This
expedites start up and assures quality control. In addition, it
facilitates machine “cool down" by allowing the tunnel
fans and conveyor to run until cooled. This assures maximum machine
component life and minimizes down time, thus assuring your greatest
Variable Speed Conveyor Control
Allows you to adjust the conveyor speed to obtain the best quality
“shrink" for your products regardless of their size or
shape. To further enhance your productivity, you can adjust the
speed to match your production line speeds to prevent shingling
or separation of product in multi-pack situations.
Digital Temperature Control
Insures consistent and uniform shrink quality by virtually eliminating
any temperature fluctuation within the shrink tunnel. Presents a
dual display read-out of both actual and set-point temperature to
provide an accurate visual indication of tunnel temperature conditions.
An added benefit of digital control is it minimizes setup and changeover
time to further increase productivity.
Adjustable Fan Speed Controls
Allows independent adjustment of air flow over all surfaces of your
package. This assures quality shrink packaging plus maximum flexibility,
no matter what the size or shape of your product. (Fan style tunnels
Adjustable Air Flow Controls
Two adjustable controls move louvers inside the tunnel chamber to
whisper air flow or run wide open. The ST 3212 and the high speed
tunnels have infeed and exit air flow controls for ultimate performance.

Teflon Mesh Conveyor Belt
This durable, non-stick belt is ideal for very small packages or
multi-packs. The design of the mesh belt facilitates even air flow
to all surfaces of your package and is essential when your product
must be transported smoothly through the tunnel .
Rod / Roller Conveyor
3/8" diameter silicone rubber covered rollers on 1-1/2"
centers transport your product through the heat chamber. As the
rollers turn, your product continually moves so there is never any
imprint or mark on the bottom of your package.
Falcon Belt Conveyor Belt
This heavy duty, glass filled nylon, open style belt is excellent

Duty Locking Casters and Leveling Pads
Belco Shrink Tunnels are mobile. You’ll find them easy to
move from one production location to another assuring maximum production
flexibility and productivity. Once in place, the tunnel's leveling
pads can be adjusted to match your conveyor height to your production
Heavy Duty Motor
Built to last. The heavy duty, variable speed gear motor has proven
to be the industry leader to assure years of trouble free and dependable
At the end of the shift, simply turn OFF the tunnel heater switch
and the conveyor switch. The machine will begin the cool down cycle
and then automatically shut-off until you are ready to begin again.
(Recirculating air style tunnels only)
Double silicone rubber re-inforced curtains form fit around your
packages. This minimizes heat loss and maintains tunnel temperature
accuracy and consistency to assure quality shrink packages.
