Compact Unit Gives
Versatility in
Designing a Heating
System
FIREROD® immersion heaters package up to 300 W/in2
(46.5 W/cm2) in a compact unit, giving you greater versatility
in designing your heating system. This design solution is ideal
for replacing large screw-plug immersion heaters.
Features and Benefits
Nickel-chromium resistance wire
• Precisely centered in the unit assures even, efficient
distribution of heat to the sheath
Magnesium oxide insulation
• Compacted to the proper density, results in high dielectric
strength and contributes to faster heat-up
Incoloy® sheath
Aside from its versatile design, these heaters come complete
with a brass 3⁄4 (19 mm) NPT double threaded screw plug,
which allows you to add conduit boxes. Also, FIREROD
immersion heaters are sealed at the lead end with a silicone
rubber seal. Solid copper leads, with silicone rubber sleeve,
are provided for unconfined wiring. These units are
recommended for immersion in water or 90+ percent water
soluble solutions.
