STARBAR TYPE TW
SILICON CARBIDE HEATING ELEMENTS







STARBAR Type TW



GENERAL DESCRIPTION



The STARBAR TW element is a higher density element, used in severe applications such as corrosive atmospheres or where normal RR type elements do not provide acceptable service life.
STARBAR TW have characteristics that their material is changed to glasses and they coat Hot zone by using at high temperature.
This is as same as SE type. TW have not any spiral cut. It is more advantageous to protect from breakages in transit, handling, or any cases.
Standard resistance is 20-40% lower than products made in Japan.
Please let us know which size you use. We are please to select exchangeable element for you.


SUPERIOR PERFORMANCE


STARBARs will give you superior performance due to their high density - approximately 2.4gms/cc. This gives the STARBAR very slow aging characteristics and additional strength.


SIZES AVAILABLE


STARBARs can be manufactured in any length up to 3300mm. The maximum hot zone length is 2500mm.



FURNACE HEATING CHAMBER


The furnace heated chamber dimension which the STARBAR spans can be the same as the hot zone length of the STARBAR as shown by the STARBARs under the load in figure 1. Alternately the furnace heating chamber dimension which the STARBAR spans can be 25mm less than the effective heating length of the STARBAR. In this case there must be a 45 degrees conical recess in the furnace wall as shown in figure 1 for the STARBARs above the load.

STARBARs should not be placed closer than two STARBAR diameters to each other or one and one half STARBAR diameter to a wall or other reflecting body. If the STARBAR is not able to dissipate heat energy equally in all directions, it may cause local overheating and possible failure. The formula for computing the recommended STARBAR spacing to obtain an even temperature gradient on the product being heated is shown in figure 1.
