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.

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.

•Compacted to the proper density, results in high dielectric strength and contributes to faster heat-up

Incoloy® sheath

•Resists corrosion from water

Metallurgically-bonded conductor pins

•Ensures a trouble-free electrical continuity

Lead end with silicone rubber seal

•Protects the heater against moisture contamination

Optional stainless steel fittings

•Available for use in corrosive applications

Horizontal through the wall tank mounting

•Makes setup faster

240 and 480VÅ(ac)

•Provides wiring flexibility

Stock availability

•Same day shipment on various 5⁄8 in. diameter heaters with
