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

are securely fastened. Various termination configurations

and options are available.

Specially selected and designed ceramic insulator

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.

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.
