FIREROD® water immersion heaters are ideal for replacing large screw-plug immersion heaters. The heater packages up to 300 W/in2 (46.5 W/cm2) in a compact unit, thus the product can be very versatile when designed into a heating system.
These water immersion heaters come complete with a brass 3⁄4 inch
National Pipe Thread Taper (NPT) double threaded fitting, 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 sleeves, are provided for
unconfined wiring. These units are recommended for immersion in water or
90+ percent water soluble solutions.
