Product Overview
Our Silicon Carbide (SiC) Heating Elements are engineered for extreme industrial heating applications. Capable of operating at temperatures up to 1600°C (2912°F), they deliver unmatched heat output, rapid thermal response, and long service life in both air and controlled atmospheres, making them a superior replacement for traditional metal alloy heaters.

Key Advantages of SiC Heating Elements

• Exceptional Power Density: Generate 5 to 10 times more heat per unit surface area than standard Nichrome wire, enabling faster heat-up and higher operating temperatures.

• Superior Mechanical Strength: Excellent resistance to thermal shock and physical deformation, ensuring reliability under rapid temperature cycling and demanding industrial conditions.

• Clean & Quiet Operation: The heat source is entirely free of noise, emissions, and air pollution, making it ideal for sensitive processes like sintering, brazing, and crystal growth.

Product Types & Applications

1. SW Type (Standard Rod)

• Applications: Universal heating element for a wide range of furnace types.

• Features: Operating range from 600°C to 1400°C (up to 1600°C in suitable conditions). Can be installed both vertically and horizontally.

• Ideal For: General high-temperature furnaces, research labs, and ceramic kilns.

2. U-Type (Hairpin Shape)

• Applications: Compact furnaces where space is constrained.

• Features: Consists of two identical SiC rods connected by a low-resistance SiC bridge, which can also serve as a mounting point. Provides a concentrated heat zone.

• Ideal For: Tube furnaces, and processes requiring a localized high-temperature zone.

3. W-Type (3-Phase Configuration)

• Applications: Large-scale industrial heating requiring high power input.

• Features: A three-rod, one-side terminal design (SGC for vertical, SGD for horizontal installation) that connects directly to a three-phase power supply.

• Ideal For: Float glass production, large batch sintering, and other heavy-duty industrial processes.

Technical Data & Properties

Operating Guidelines & Atmosphere Compatibility

The performance and lifespan of SiC elements are highly dependent on furnace temperature and atmosphere. The table below provides key recommendations and warnings.

Critical Installation & Usage Notice

• Storage: Keep elements dry and protected from moisture to prevent performance degradation.

• Matching: For multi-element furnaces, sort and group elements so their resistance values are within a 10% tolerance to ensure even load distribution.

• Handling: SiC is hard but brittle. Handle with care during installation and maintenance to avoid breakage.

• Start-Up: Always use a controlled ramp-up voltage when starting a cold furnace. Avoid immediate full power to prevent excessive inrush current from damaging the elements.

• Replacement: Replace damaged elements with new ones of similar resistance. If multiple elements have failed or their resistance has increased significantly, consider a full set replacement for balanced performance.
