through the heating and
cooling zones, depositing
them into the unloading bin.
• Over-temperature switch
that shuts off all power in
the event of an overheat
condition
Applications
The Model 20 conveyor
type processor is a reliable
and versatile process
heater, which provides a
controlled process for a
wide variety of heat-shrink-
able products.
Versatility
• Lockout on temperature
and speed controllers to
prevent unauthorized
changes
The processor is designed
to process a broad range of
Raychem heat-shrinkable
products up to 25 mm [1 in]
in diameter and 127 mm [4 in]
in length. The infrared
Double-sided timing belts
on either side of the upper
and lower heating cham-
bers draw the assemblies
through a thermally con-
trolled infrared heat zone,
then through a fan-cooled
zone before depositing
Speed Control
New Features
The belt speed is selected
using a 3-digit thumbwheel
(on the front panel) via a
closed-loop motor controller either single wall or adhe-
and DC gear motor.
• Self-locking support post
in the upper heating
chamber for servicing,
maintenance and emer-
gency cool down
energy source is well-suited
to efficient processing of
sive-lined tubing. Temperature
and speed can be con-
trolled to accommodate a
wide variety of products
and substrates.
• Reversing motor relay
which runs the timing
belts in reverse until the
Set Point temperature has
been reached, preventing
the operator from loading
assemblies into the
them into the unloading bin.
Minimal Skill Requirements
There are clearly marked
guides for aligning the
assemblies as well as the
tubing or device being
processed. The operator
only has to center the sub-
strate, then align the tubing
and slide the assembly into
the belts. The belts grip
and carry the assemblies
Controlled Heating Zone
The Model 20 processor
has two stamped foil heat-
ing elements that are manu-
factured to a strict wattage
specification. Consistent
temperatures (ambient to
700ºC) are controlled by a
thermocouple embedded
Safety Features:
• Emergency Stop
machine
• Automatic cool-down cir-
cuit to extend the life of
the components
• Hinged lower side panels
for access to compo-
nents, making routine
service and maintenance
much easier
