U Type Silicon Carbide Heating Element
GDU shape silicon carbide heating element is using two hot zones, compared with GD shape silicon carbide heating element less two cole zones, you can save 10-20% power when you use GDU shape silicon carbide heating element, the maximum using temperature is 1500 ℃
- The highest temperature could reach 1500℃
- Durable with super long working life
- High strength and excellent shock resistance
- Free of noise and air pollution, environmentally friendly
Product Description
GDU Type silicon carbide heating elements are made of special high-density reaction-bonded silicon carbide. They have a spiral slot in the hot zone that reduces the cross-sectional area, which provides the electrical resistance ratio to make the ends cool and the hot zone hot. They have special cold ends that may be customized according to specific requirements
