Screw Heater

A Screw heater, also known as a screw plug heater or threaded immersion heater, is a type of electric heater used to heat liquids and gases in tanks and vessels. It consists of tubular heating elements welded or brazed into a threaded plug that screws directly into a threaded opening in the tank wall or vessel. This design allows for easy installation and efficient heat transfer directly into the heated medium.
