Type SEU, Silicon Carbide Heating Elements

Check up to five results to perform an action.


Made of special high-density reaction-bonded silicon carbide, the SEU Starbar is a tube with both electrical connections on one end. The hot zone is formed by cutting a slot, which reduces the cross sectional area over which the current flows, resulting in higher resistance than the cold end. The cold end is formed by cutting two longitudinal slots along the length of the tube and is made of LRE (low resistance end) material and in most cases is larger in diameter.

The SEU element is supplied with a ceramic collar cemented to the cold end. The cold end of the SEU element is flame sprayed with aluminum for a distance of about two inches. Flat, braided-aluminum straps are held in compression with a stainless steel clamp to this metallized area. The clamp is electrically insulated from the flat braid with high temperature insulation. The aluminum braid is ten inches long and holes are provided for easy connection to the power supply.

The electrical resistance of the SEU can be customized by varying the spiral width. SEU Starbars can range from high resistance to low resistance. The electrical resistance can be as high as the SER (spiral element with return) and as low as the RR (rammed type) non-spiral Starbar. There are further limits based on the size of the SEU.

SEU Starbars are described by giving the overall length, the heating section length, and the diameter. As an example, SEU 45 x 30 x 1-1/4 is a SEU Starbar, 45" overall length, 30" hot zone, and 1-1/4" hot zone outer diameter. In metric, SEU 1143 x 762 x 32 is a SEU Starbar, 1143 mm overall length, 762 mm hot zone and 32 mm hot zone outer diameter.
