Type SER and TSR, Silicon Carbide Spiral Heating Elements

Check up to five results to perform an action.

General Description SER

Made of special high-density reaction-bonded silicon carbide, the SER Starbar is a tube with both electrical connections on one end. The hot zone is formed by cutting a double spiral slot which reduces the cross sectional area through which 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. The SER element is supplied with a ceramic collar cemented to the extremities of the cold end. The cold end of the SER element is flame sprayed with aluminum for a distance of about two inches. Flat braided-aluminum straps are held in compression with stainless steel clamps to this metallized area. The clamp is electrically insulated from the flat braid with high temperature insulation. The aluminum braid is 10 inches (254 millimeters) long and holes are provided for easy connection to the power supply.

General Description TSR

Available in five different diameters, TSR Starbars feature a large inner diameter used as a heating chamber. With both electrical connections on one end, the TSR Starbar is similar to the SER Starbar. The TSR Starbar has a thin wall construction and a clear inner diameter which makes it useful for tube furnace applications. The TSR does not normally require a collar, but one is available. The flat braided-aluminum straps are held in place with a stainless steel clamp. The clamp is electrically insulated from the flat braid with high temperature insulation.

SER and TSR Starbars are described by giving the overall length, the heating section length, and the diameter. As an example, SER 24 x 16 x 1.25 is a Spiral Starbar 24 inch long with a 16 inch hot zone and an outside diameter of 1.25 inch. In millimeters an SER 610 x 406 x 32 is a Spiral Starbar 610 mm long with a 406 mm hot zone and an outside diameter of 32 mm.
