DB ( Dumbbell ) Type Silicon Carbide
Compared to other heating elements, the silicon carbide (SiC) heating element stands out for several reasons. Its non-metallic construction makes it more resistant to corrosion and oxidation than metallic heating elements. The ultra pure green hexagonal silicon carbide material provides superior thermal properties, allowing for operation at high temperatures and a long service life.
In contrast to the earlier dumbbell shaped components with enlarged cold ends, the modern non dumbbell or ED type components offer a more compact and efficient design. The oversized cold ends of the earlier design were necessary due to limitations in materials and technology. However, with advancements in manufacturing processes and the development of new materials, the need for such large cold ends has been eliminated.
The non dumbbell or ED type components also have lower electrical resistivity, which results in more efficient energy transfer and reduced power consumption. This makes them a more environmentally friendly and cost-effective option.
