Introduction
The Model E4 elliptical chamber is designed for rapid heating of small size continuous materials
such as tube, cable, and wire with an outer diameter from 0.25 to 0.125 inches in diameter. It
may also be used as a high temperature furnace in test applications. The E4 is available in
seven different lengths. Typical applications for these heaters
include:
• Curing small-diameter silicone tubing
• Re-glossing
small-diameter plastic tubing
• Burning lubricant off extruded wire
• Curing coatings or adhesives on wire or cable
• Drying water from wire or cable
• Preheat wire or cable
Description
The Model E4 focuses high-density infrared energy, generated by 'T3-style', halogen lamps,
onto a cylindrically shaped target area. The heater is hinged so it can open and close in a
clamshell style, for easy access.
Reflectors
Four elliptical reflectors (see Figure 1) focus the infrared
energy supplied by T3 lamps toward the heater center axis.
The reflectors are constructed from aluminum polished to a
specular finish and are available in heated lengths of 2, 5, 6,
10, 16, 25, and 38 inches (51,127, 152, 254, 406, 635, and
965 mm).
Lamps
Included are four high intensity, short wave, 'T3-style', infrared
lamps. The tungsten emitter in the lamps has an operating
temperature of 2500
°K with a spectral energy peak
wavelength of 1.15 microns. Each Model E4 requires four lamps to operate. The lamps are
included with the Model E4.
Water Cooling
The Model E4 requires an external water-cooling supply to cool the reflectors. Refer to table 1
for flow rates depending upon model.
Benefits
Fast
T3 lamps heat up and cool down instantly in response to power control signals. They reach 90
percent of full operating temperature within three seconds from a cold start. The radiant energy
