Safety Features
The VBH-1 is an integrated
modular unit consisting of
an upper and lower heater
chamber with a transporter
base and motorized wheels
that are directed through an
aluminum track. The heater
transporter automatically
stops when it reaches the
parking station at either end
of the process area.
The belt speed is selected
using a 3-digit thumbwheel
(on the front panel) via a
closed-loop motor controller operator simply place the
and DC gear motor.
The open loading area of
the holding fixtures on the
VBH-1 requires that the

Controlled Heating Zone
The VBH-1 processor has
two stamped foil heating
elements that are manufac-
tured to a strict size and
wattage specification.
Consistent temperatures
(ambient to 650ºC) are con-
trolled by a thermocouple
embedded into the upper
heating element connected
to a closed loop tempera-
ture controller. An alarm
light illuminates whenever
the actual heating element
temperature varies from the
set point temperature.

adjustable upper heating
chamber the heater separa-
tion can be adjusted from
37 mm [1.5 in] to a 150 mm
[6 in] gap enabling the unit
to process heat-shrinkable
tubing products up to 127
mm [5 in} in diameter. The
upper and lower chambers
are provided with adjustable
heat shields to maximize
the oven heating efficiency.
The traveling heater is
designed to process a
broad range of heat-shrink-
able products up to 127
mm [5 in] in diameter and
infinite length.
The infrared energy source
is well-suited for efficient
processing of either single-
wall or adhesive-lined tubing.
Heat output and drive speed
can be controlled to accom-
modate a wide variety of
products and substrates.
