U/W Dumbbell typeSilicon Carbide/SIC Rod heating element for melting furance

Product Application
Used in various high temperature electric furnaces and other electric heating devices, such as in the industries of magnet, ceramics, metallurgy, glass, and machinery.

Detailed Features of SIC heater:

1. U Type SIC heater
SIC heaters are constructed to from a U-shape. Consequently Type U have the terminals at one end for a single-phase power source. This reduces the number terminations and cold ends thus enabling energy savings.

2.W Type SIC heater
SIC heater with the terminals at one end, is designed for three-phase power source applications, such as the float glass process.

3.Spiral Type SIC heater
SIC heater with a spiral-grooved heating section, are more resistant to heat and corrosion than conventional products and are able to withstand operation in rigorous conditions. Single spiral elements are provided with energy-saving, low-resistance, cold-end terminals.

4.Double Spiral Type SIC heater
SIC heater with a spiral-grooved heating section, are more resistant to heat and corrosion than conventional products and are able to withstand operation in rigorous conditions. Double spiral elements are provided with energy-saving, low-resistance, cold-end terminals.

5.GC ( Dumb bell type )and GD (Rod)Type SIC heater
GC and GD type SIC heater is made from high-density,high-purity silicon carbide ,which is the most popular type of economical heating element capable of operating under hot and rigorous environments.

Notice for using and installing SIC heater

1. Be protected against damp during storing or installing to ensure the performance ;

2. Divided before assembling. The tolerance of the resistance of each one cannot exceed by 10% each other;

3. Be careful when using and maintaining;

4. When operating the electric furnace at the beginning, the voltage should be increased slowly and cannot be fully loaded at once. Otherwise the larger current will be resulted in the damage of heater. 

5. When heater is damaged and need to be changed, the resistance of new ne should follow the increasing resistance. If many are damaged or resistance increased too much, heater should be changed.
