Application Equipment
Applications
The Model 81CE is a CE
Certified discrete-type table
top heater which provides a
controlled process for
recovering a wide variety of
Raychem heat-shrinkable
products onto wire assem-
blies or other suitable sub-
strates.
Assemblies are loaded into
spring loaded jaws on
either side of the heating
chamber which takes the
assemblies into the oven for
a pre-set number of sec-
onds, then returns them to
the home position for
removal.
Controlled Heating Zone
The Model 81 CE processor
has two stamped foil heating
elements that are manufac-
tured to a strict wattage
specification. Consistent
temperatures are controlled
by a thermocouple embedded
into the upper heating ele-
ment connected to a closed
loop temperature controller.
An alarm light illuminates
whenever the actual heat-
ing element temperature
varies from the set point
temperature.
Controlled Oven Dwell Time
The oven dwell time is
selected using a 3-digit
thumb wheel digital timer.
The time can be set
between 1 and 999 sec-
onds for precise heating
ensuring each assembly
being processed sees the
same precise amount of heat.
Minimal Skill Requirements
There are clearly marked
guides for aligning the
assembly as well as the
tubing or device being
processed. The operator
only has to center the
assembly, then the tubing,
and load it into the spring
loaded jaws on either side
of the heating chamber. The
jaws grip and carry the
assembly into the heating
chamber and back to the
home position when the
time has expired. A protec-
tion circuit prevents the
cycle from being initiated if
the oven is not at the
desired set point, prevent-
ing assemblies from being
processed incorrectly. The
small footprint allows the
processor to be placed in
close proximity to a welder,
allowing a single operator
to accomplish two tasks.
Versatility
The processor is designed
to process a broad range of
Raychem heat-shrinkable
tubing products up to
25 mm [1.0 in] in diameter
and 127 mm [5.0 in] in
length. The infrared energy
source is well-suited to effi-
cient processing of either
single-wall or adhesive-
lined tubing. Temperature
and time can be controlled
to accommodate a wide
variety of products and
substrates.
Safety Features:
• Circuit breaker for current
surges
• Emergency Stop
• Pinch points eliminated
by the housing design
• An over-temperature
switch that shuts off all
power in the event of an
overheat condition
• Automatic cool-down cir-
cuit to prevent heat dam-
age to integral
components
• Circuit to prevent cycle
initiation until the oven is
up to temperature
