Features & Benefits of the Watlow® Immersion Heater

The integral thermowell provides a convenient method for temperature sensor insertion and allowing a replacement without draining the fluid being heated. The CSA approved general purpose enclosure can be rotated to simplify connecting to existing conduits. The heating element hairpin bends are re-compacted to maintain the mineral insulation density and maintain the dielectric strength and heat transfer efficiency. The heating elements have a bright annealing passivation for corrosion resistance and the screw plug is also 316SS.

NOTE: A NEMA-7 enclosure designated for locations classified as Class-1, Division-1, Groups A,B,C, or D as defined in NFPA 70 is installed on this heater; however, is NOT CERTIFIED as installed on the heater. To obtain CSA certification as explosion proof Class-1, Groups B,C,D as installed on the heater, the end user must provide Watlow® the following intended process conditions: operating temperature, operating pressure, media type being heated, including the installation orientation of the heater (horizontal or vertical).

• One conduit hub is supplied as per provided drawing above.
