Introduction
The Model 4069E ExtrudeIR curing System uses high intensity infrared lamps and
polished aluminum reflectors to deliver heat precisely where it is needed for many curing
and drying applications on extrusion lines. It can be used effectively to provide a surface
cure to rubber extrusions, dry adhesives and coatings on rubber or metal, and provide in
process curing between layers of multi layer cable. Depending on the model selected,
diameters as small as ¼ inch or a large as 4 inches can be processed. This system
includes, along with the Model 4069 ChamberIR heater, an operator interface pedestal
with a Watlow PID controller, a split quartz liner, height adjustment with plus/minus 15
degrees of tilt off horizontal, and convenient connection points for power, water and air.
Optional features that can be ordered with the unit include an optical pyrometer to monitor
product temperature, product break sensing to shut power down if the line brakes, and an
air nozzle kit to provide forced air inside the heating chamber to increase efficiencies in
curing and drying.
The single chamber models are an efficient solution for most applications and the dual
chamber models provide additional product support to allow fragile product to run through
the system without breaking or drooping
Typical applications for the Model 4069E include:
Surface cure on rubber extrusion
Drying adhesives and coatings on rubber or metal
Soften and Cure between multi-layer extrusions
Cast and hold the shape extrusion
Flash cure coatings between operations
Heater Module –A circular array of individual parabolic polished aluminum reflectors
direct the infrared energy generated by the quartz lamps towards the center axis of the
heater. Each heater houses either 12 or 18 reflectors, depending on the model. The 12
reflector model accepts product sizes up to 2 inches in diameter while the 18 reflector
model accepts products up to 4 inches in diameter. Heated lengths of 10, 16, 25, and 38
inches (254, 406, 635, and 965 mm) are offered for the Model 4069E. For applications
prone to product sagging a dual heater system with two 10” heated length chambers and a
intermediate product support between them is available. The chamber’s clam shell design
offers easy access for liner cleaning and lamp servicing by simply releasing the latches on
the front of the chamber and lifting the upper half. Gas springs are provided to assist with
the left gas spring having a integral extension lock. The factory installed ceramic end seal
T3 style lamps provide precise levels of power to the product in the chamber. The lamps
generate infrared energy at a peak wavelength of 1.2 microns at rated voltage. This
wavelength is commonly known as short wavelength or NIR, (Near Infrared). The lamps
reach 90% of full operating temperature within three seconds of a cold start. Radiant
energy is dissipated to 10% five seconds after power is shut down. Additional lamps can
be ordered separately from the heater.
