Screw Plug Immersion Heaters

Mount these heaters securely to industrial tanks and other vessels using a threaded opening in the wall. They can also be screwed directly into a pipe that carries liquid using a coupling. The heating element is brazed or welded onto the threaded plug.

For Water

Heat pure or deionized water for use in cleaning and rinsing parts, freeze protection, and sprinkler systems. Heaters without thermostats require an external overtemperature or flow switch, or some other safety device.
