Single Spiral Silicon Carbide Heating Element
The GD/HGD shape silicon carbide heating element is composed of three parts: a central hot zone and end cold zones. It can operate at a maximum temperature of 1500°C.
- The highest temperature it can reach is 1500°C.
- Durable with an exceptionally long service life
- High strength and outstanding shock resistance
- Operates free of noise and air pollution, making it environmentally friendly
Product Description
Single spiral silicon carbide heating elements are crafted from high-density reaction-bonded silicon carbide. They feature a spiral slot in the hot zone that reduces the cross-sectional area, creating an optimal electrical resistance ratio. This design ensures that the ends remain cooler while the hot zone achieves high temperatures. Additionally, the cold ends can be customized to meet specific requirements.
