Radiant heaters
General description:
Heating elements made of silicon nitride are very suitable as radiation heaters. The almost black silicon nitride used for the heating elements is a long-wave infrared radiator with a maximum radiation emission (ε > 0.8) between 8 and 11 µm at 1 000 °C. Thus, a wide variety of materials can be heated effectively by radiation: Sheet metals to be selectively heated or held at temperature for subsequent re-forming processes, as well as plastics where the weld edges are to be melted for a subsequent sealing process. In addition, plastics can be selectively "glued", or sharp edges can be rounded or thermally deburred by radiant heat. Radiation heaters with the dimensions 210 mm x 14.5 mm x 4.4 mm are available in a large number of different power ratings. However, they can also be equipped with sensor boreholes for thermocouples, in order to be able to precisely control the temperature of the heating element. The robust design of these heating elements, in conjunction with the good oxidation resistance of the silicon-nitride ceramics, ensures a long service life - both during continuous operation and during cyclic demand.
