Tubular heating elements

Screw plug immersion heater with galvanic insulated elements

Screw plug immersion heater for direct heating of liquids. The tubular elements are galvanic isolated from the screw plug. The galvanic insulation of the tubular element reduces the risk for electrical leakage and also contributes to a longer live time for the anode.
