GENERAL
FIRE/EXPLOSION HAZARD. Do not exceed the
Pressure-Temperature rating of the flange as listed in
ANSI B16.5.
Chromalox TM- Series industrial flanged immersion heaters are
designed for a wide variety of heating applications.
1. Heater Construction Characteristics:
A.
High quality resistance wire held in place by compacted
Magnesium Oxide Refractory enclosed in a wide variety of
sheath materials.
B.
Low to high watt densities.
C.
Standard selection of sheath materials include copper, steel,
INCOLOY
®
alloy and stainless steel. This broad selection of
sheath materials will operate successfully in many corrosive
solutions.
IMPORTANT: It is the responsibility of the purchaser
of the heater to make the ultimate choice of sheath
material based upon their knowledge of the chemical
composition of the corrosive solution, character of the
materials entering the solution, and controls which he
maintains on the process.
FIRE/EXPLOSION HAZARD. Sheath corrosion can
result in a ground fault which, depending upon the
solution being heated, can cause an explosion or fire.
D.
Pipe flange sizes in 3, 5, 6, 8, 10, 12 and 14 inches are standard.
Other sizes are also available.
E.
Units are available with E1 General Purpose, E4 Moisture
Resistant and E2 Explosion/Moisture-Resistant terminal enclo-
sures.
FIRE HAZARD. An integral thermostat, if provided, is
designed for temperature control service only.
Because the thermostat does not fail safe, it should
not be used for temperature limiting duty. Wiring to
this device is the responsibility of the user.
The system designer is responsible for the safety of
this equipment and should install adequate back-up
controls and safety devices with their electric heat-
ing equipment. Where the consequences of failure
could result in personal injury or property damage,
back-up controls are essential.
