Screw plug heaters are compact, high-efficiency immersion heaters designed for direct heating of liquids and gases in tanks, vessels, and pipelines. The heating elements are brazed or welded into a threaded plug, allowing easy installation into standard NPT or BSP threaded openings.
These heaters offer rapid heat-up, uniform temperature distribution, and minimal heat loss, making them ideal for applications ranging from water and oil heating to chemical processing. Available in a variety of sheath and plug materials, screw plug heaters can be configured for safe operation in hazardous or corrosive environments.
