Agency Approvals
Channel Strip Heaters have been certified as
Recognized Components by Underwriters Laboratories
(File Number E65652) under CCN KSOT2/8 to meet UL
standard 499 and Canadian Standard C22.2, No 72.
This file specifies the end use limitations and
conditions of acceptability for the use of this type of
heater. For additional information consult OMEGA.
If you require UL, CSA, or other NRTL Agency
Approvals, please specify when ordering.

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.
