Silicon Carbide Heating Elements - U-Type

The S4R Silicon Carbide Heating Elements - U Type are high-temperature electrical resistance heating elements designed for laboratory furnaces, muffle furnaces and thermal-processing systems requiring both electrical connections to be located on the same side of the heating assembly.

Manufactured from silicon carbide (SiC), the U-shaped configuration combines two parallel element legs connected at one end, providing a compact solution for furnace designs where installation space or terminal accessibility makes a straight element impractical.

The S4R standard range includes 1400°C and 1500°C temperature grades in selected laboratory-furnace dimensions. Custom dimensions and electrical resistance specifications are available on request.

For correct selection, both the mechanical dimensions and nominal electrical resistance must be matched to the furnace electrical system.

Dimensional Reference
U-type silicon carbide heating element — dimensioned schematic Side view of a U-shaped SiC element. The dark central span is the heating zone; the two light-coloured straight ends are the cold end or terminal zone. Three dimensions are called out: A overall length, B overall width outside to outside, and C element outside diameter. Nominal values are listed in the table below. A B C Heating Zone Cold End / Terminal Zone
Schematic representation — not to scale. Overall length A is measured to the tips of the terminal zone. Leg centre distance equals B minus C.
Nominal Dimensions
Temperature Grade A Overall Length (mm) B Overall Width, outside to outside (mm) C Element Outside Diameter (mm)
1400°C 500 42 12
1500°C 300 40 12
1500°C 270 42 12
All dimensions are nominal values in millimetres. Alternative dimensions and temperature grades are available on request.
Element Selection
Element Dimensions Match the furnace installation geometry and S4R technical drawing
Temperature Grade Select according to the intended furnace operating conditions
Nominal Resistance Must be selected according to the furnace electrical design
Technical Notes
• Element dimensions and nominal resistance should both be verified before installation.
• For furnaces using multiple elements, resistance-matched elements may be required according to the electrical design.
• Silicon carbide heating elements are brittle and should not be subjected to excessive mechanical stress during installation.
• Maximum recommended operating conditions depend on the selected element grade, furnace atmosphere and complete system configuration.
• Voltage and power requirements depend on the selected nominal resistance and furnace electrical system.
