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 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 elements have a support to ensure proper spacing to maximize the heater’s performance.

Ideal Immersion Heating for Liquids & Oils using Heat Transfer Solutions.
