GENERAL (cont’d.)
D. Riser type construction puts the heat at the bottom inducing
natural “stirring action” and evenly distributed temperatures.
E. Units are available with E1 General Purpose, E4 Moisture
Resistant, E2 Explosion/Moisture Resistant and E3 Explosion
Resistant terminal enclosures.
IMPORTANT: It is the responsibility of the purchaser of
the heater to make the ultimate choice of sheath
material based upon his knowledge of the chemical
composition of the corrosive solution, character of
the materials entering the solution, 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.
Sheath corrosion can result in a ground fault which,
depending upon the solution being heated, can cause
an explosion or fire.
