Installation and Maintenance Guide

Step by Step Installation

• Horizontal Mounting

  Secure the double-spiral silicon carbide heating element in a clean, dry position. Ensure terminals are accessible for wiring. Use proper clamps to avoid stress on the element.

• Vertical Mounting

  Position the heater so the spiral grooves are vertical. Check for even support along the length to prevent bending. Leave space for thermal expansion.

• Expansion Allowances

  Silicon carbide expands when heated. Allow at least 3-5% length clearance in mounting to prevent cracking or warping during operation.

Maintenance Tips

• Resistance Aging

  Monitor element resistance regularly. A rising resistance typically means aging or damage. Track baseline resistance after installation for comparison.

• Clean Atmosphere

  Keep the furnace atmosphere clean and free of contaminants. Avoid exposure to moisture or debris which can accelerate element degradation.

• Regular Inspection

  Look for signs of oxidation or cracking. Replace elements at the first sign of wear to avoid downtime.

FAQ

How to Calculate Element Resistance

Resistance depends on element length, cross-section, and material properties. Use the formula:
R = ρ x (L / A)
Where R = resistance, ρ = resistivity of SiC, L = length, A = cross-sectional area. For exact specs, refer to the technical sheet or ask our team.

Is this Element Compatible With Kanthal Furnaces

Yes, the double-spiral silicon carbide element works well with most Kanthal-type industrial furnaces. Always check voltage and current specs before installation.
