Screw plug immersion electric heaters are one of the most widely used methods of heating gases and liquids such as water, oil heat transfer fluids and corrosive fluids.
Designed for use in tanks and pressurized vessels, they are easy to install and maintain and provide heat for many processes. The direct immersion method is energy efficient and easy to monitor and control.
