Tubular heating element

ceramic

The ceramic heating elements are most frequently used whenever liquids must be heated by exchangeable heating elements. To this effect, these heating elements are inserted into metallic protective tubes; it is not necessary to drain the liquid surrounding the pipe. Ceramic heating elements can be produced for a variety of diameters. The following list shows the most frequent diameters; in addition, intermediate dimensions are also available. I. Usual dimensions 21,5 mm 32 mm 36,5 mm 58 mm Insulator Ceramic preformed parts are used as an insulator, accepting the heating contactor wire in half-open grooves, thus ensuring a sufficient isolation distance to the metallic protective tube. Heating conductor Highly heat-resistant alloys are used for the heating conductor. The heating conductor wire is held in the ceramic design in a spiralized condition. Types of mounting Horizontal This is the preferred mounting method for ceramic heating elements. Unless otherwise specified, ceramic sectional radiators must only be operated in a horizontal position. Vertical The sinking of the heating conductor spiral can be prevented by special ceramic designs for vertical operation. Normal ceramic heating elements require at least the length of the heater space for an installation and a removal since the heater cannot be bent. Our ceramic heating elements can partially be designed for bending by a special ceramic variant.
