Product Description
SPK silicon carbide heating elements are manufactured from recrystallized high purity alpha silicon carbide rod or tubular form. Optimized structure of SiC particles make it have special characteristics as applied in industry and lab, which have the best service life particularly in oxidation and/or corrosive atmospheres. SPK SiC elements may be mounted either vertically or horizontally at the Max. operation temperature 1600℃ without any special supports, the elements will not deform. This provides a flexible furnace design for maximum interior design. Another feature is that elements can be replaced when the furnace is in continuous operation, thus avoiding a shutdown. Its high loading capacity is suitable for low-volume and high power conditions. Therefore, it is widely used in various high temperature electric furnaces and other electric heating devices, such as industrial applications involving magnetic, ceramics, powder metallurgy, glass, metallurgy and machinery.
The Wide U (WU) shape element is a heating element that has two cold ends, welded at right angles to the opposite ends of the hot zone. The maximum recommended furnace temperature is 1425ºC (2600ºF). The element is manufactured of high density recrystallized silicon carbide. The two cold ends are low resistance silicon carbide. The diameters available range from 12 to 54mm and hot zone lengths up to 1500mm and cold ends up to 480mm long.
