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 WATROD™ hairpin bend is 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 316SS.
