GENERAL
FIRE/EXPLOSION HAZARD: This heater is not
intended for use in hazardous atmospheres where
flammable vapors, gases, liquids, or other com-
bustible atmospheres are present as defined in
the National Electrical Code. Failure to comply can
result in explosion or fire.
Chromalox type GS and GT over-the-side immersion heaters
are designed primarily for corrosive baths and available in a vari-
ety of sheath materials. 316 stainless steel and titanium sheets are
standard.
Sheath corrosion can result in a ground fault
which, depending upon the solution being heated,
can cause an explosion or fire
IMPORTANT: It is the responsibility of the pur-
chaser of the heater to make the ultimate choice
of sheath material based upon his knowledge of
the chemical composition of the corrosive solu-
tion, character of the materials entering the solu-
tion, and controls which he maintains on the
process. Chromalox cannot warrant any electric immersion
heater against failure by sheath corrosion if such failure is the result
of operating conditions beyond our control.
1. Heater Construction Characteristics
A. High quality resistance wire held in place by ceramic core and
magnesium oxide in various sheath materials.
B. Medium and low watt densities.
C. Epoxy filled cavity to prevent entry of contaminants.
D. Over-temperature protection.
E. Flexible conduit 3’ long with 6” leadwire extension.
The system designer is responsible for the safety
of this equipment and should install adequate
back-up controls and safety devices with their
electric heating equipment. Where the conse-
quences of failure could result in personal injury
or property damage, back-up controls are essen-
tial.
