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.
