SCR Double Spiral Silicon Carbide(SiC) Heater Rod


The silicon carbide (SiC) heating element is a kind of non-metal high temperature electric heating element. It is made of super quality green silicon carbide, which is made into blank, solid rod under high temperature and re-crystallized. Compared with metal electric heating element, this element takes advantages of high-applied temperature, anti-oxidization, anti-corrosion, long service life, little deformation, easy installation and maintenance.
