Type 304 Stainless Steel sheath provides the best
A
combination of physical strength and resistance to high
temperatures and chemical corrosion. Dependable at sheath
temperatures of up to 650°C (1200°F).
Stainless Steel 10-32 threaded screws are standard and
B
are securely fastened. Various termination configurations
and options are available.
Specially selected and designed ceramic insulator
C
houses the resistance wire coil, insulating it from the
outer sheath.
Helically wound resistance wire coil made from nickel-
D
chrome wire is evenly stretched and precisely strung
through the ceramic insulator, providing uniform heat.
Resistance wire is then mechanically connected to screw
terminals or lead wires for a strong positive joint.

A custom mixture of several high purity magnesium oxide
E
grain sizes, chosen to increase thermal conductivity and
dielectric strength, are used to fill all remaining space inside
and around the ceramic insulator. Voids are densely packed.
Channel strip heaters are available with or without

mounting tabs. If without, the ends are silver soldered
shut to prevent moisture and contaminants from entering the
heater. Tabs are not available on 6.35 thick x 16 mm wide

Strip Heaters
Channel Strip Heaters
Ceramic Insulated
Channel Strip Heaters have proven to be extremely efficient
and dependable as a heat source for surface heating in
hundreds of industrial and commercial applications. The
rectangular tube gives full surface contact when used in a
milled slot to provide maximum heat transfer area.
For surface mounting installations, channel strip heaters
must be securely clamped along their entire length to a
smooth metal surface. When supported by mounting tabs,
the terminal end should be secured firmly. Opposite end
should be loose to allow for thermal expansion.
