Specification :

Dumbbell heating elements consist of a hot zone with high electrical resistivity
and are rigidly connected with two thickened cold ends of low resistance owing
to their larger diameter and special manufacturing technique. The particular
connecting technique ensures perfect mechanical and electrical operation. The hot zones and cold ends are made of exceptionally homogeneous, self-bonded silicon carbide.

The Yuhao Dumbbell type sic heat element is manufactured in a range of 8 to 45rnrn inhot zone diameter, 150 to 3, gggrnrn in hot zone length and 300 to 4, 500rnrn in total length. The heating rods are self-supported and can be installed vertically or horizontally. The table is common sizes.

Yuhao sic heating element:
SiC heating elements have a long working life
silicon carbide heating elements is very easy to changed.
SiC heater is very clean and environmental
silicon carbide heating elements have a lower price
sic heating elements will give you more convenient
sic heater is very popular in the world for furnace heater
Yuhao silicon carbide heating elements is the best in China.
Yuhao SiC heating elements is the best choice for furnace
Yuhao SiC heater have many advantage compare with Metal heater.
