DB Dumbbell Silicon Carbide(SiC)Heating elements

Dumbbell consists of a hot zone with high electrical resistivity and two thickened cold ends of low resistance due to their larger diameter. Hot zones and cold ends are made of exceptionally homogeneous, self-bonded silicon carbide. These elements are self supporting and can be installed vertically or horizontally.
