The S4R Molybdenum Disilicide Heating Elements — U-Type are electrical resistance heating elements designed for high-temperature laboratory furnaces and thermal-processing systems.

Manufactured from molybdenum disilicide (MoSi₂), the U-shaped configuration combines two parallel heating legs with enlarged terminal sections positioned on the same side of the furnace assembly. The standard S4R range uses a 6 mm heating-section diameter and 12 mm terminal-section diameter, with several combinations of heating-zone length, terminal length and spacing dimension.

Standard configurations are available for laboratory furnace integration, while custom dimensions and electrical resistance specifications can be supplied on request.

For correct selection, the mechanical dimensions and the required electrical characteristics should be matched to the furnace design.

Dimensional Reference
Molybdenum Disilicide Element — U-Type
MoSi2 U-type heating element — dimensioned schematic Side view of a hairpin-shaped molybdenum disilicide heating element with heating section, enlarged terminal shanks, overall length, heating-section length, terminal-section length, element diameters and shank spacing. L D L1 L2 d1 d2 Heating Section Terminal Section
Schematic representation — not to scale. The five dimensions d1, d2, L1, L2 and D define the reference and are quoted in that order, for example 6 × 12 × 120 × 170 × 40. Overall length L is given for reference and equals L1 + L2, measured from the outside of the bend to the terminal ends. Shank spacing D is measured centre-to-centre.

Custom Configuration Alternative dimensions can be specified for application-specific requirements
Technical Notes
• Verify both dimensional compatibility and electrical requirements before installation.
• For systems using multiple heating elements, resistance matching may be required according to the furnace electrical design.
• Heating elements should be handled carefully and protected from excessive mechanical stress during installation.
• Voltage and power requirements depend on the selected electrical resistance and complete furnace electrical system.
• Actual operating conditions depend on the selected element configuration and complete furnace system.
