Ceramic Heating Elements

Round ceramic heating elements are primarily used for indirect heating of water, liquids, oil products, ovens and machines. In particular ceramic heating elements are integrated into vessels and containers where the heating element is placed in a tube which is welded or screwed into the vessel. This installation method is an advantage when using direct heating as the heating element can be replaced without emptying the vessel. Ceramic heating elements are also a perfect solution for heating oil and bitumen, as the medium may burn onto the surface of the heating elements due to the high temperatures created during direct heating.

Application

By using a tube it is also possible to achieve a large surface for heat distribution and therefore to install a high output.
The table below includes our standard range and gives an indication of guiding load values and connections.

Construction

Ceramic heating elements are made of ceramic blocks which, regardless of the diameter, have a length of +/- 50 mm. The ceramic blocks are assembled to complete heating elements with the heating conductor placed in the ceramic grooves and when using large diameters the  ceramic elements can be up to 10 – 11 meter long.

If the element should be installed in vertical position the heating conductor will be fixed to prevent it from ”sagging” during use.

If the heating element is built into a welded pipe and installed horizontally, the welded seam must point upwards so that the surface creeping distance will not reduce.

The stated wattage is only intended as a guide in connection with choice of physical measures. When preparing the final dimensioning it is important to compensate for the position of the heating element (ability to give off heat to the medium), operation and surrounding temperature.
