# W-Type SiC Heating Elements ## W-Type SiC Elements Description CVSIC W-Type Silicon Carbide (SiC) Heating Element (M-Type) is crafted from high-purity, high-density SiC particles using a dry self-bonding process, shaped in a “W” configuration with three heating units designed for three-phase power applications. The hot zone surface temperature reaches up to 1600℃, with a maximum operating temperature of 1625°C (2957°F), delivering energy efficiency, a long lifespan, and excellent thermal uniformity, making it perfect for float glass production and other high-temperature industrial kilns. ### SiC Heating Elements ResistanceTemperature Performance Graphs ![cvsic sic heating elements resistancetemperature performance graphs](https://cvsicelement.com/wp-content/uploads/2025/08/CVSIC-SiC-Heating-Elements-ResistanceTemperature-Performance-Graphs.webp) ### Ordering Information When ordering W-Type Silicon Carbide Heating Elements, please provide the following parameters: - **OD**: Outer diameter (mm) - **HZ**: Hot zone length (mm) - **CZ**: Cold zone length (mm) - **OL**: Overall length (mm) - **A**: Shank spacing (mm) - **D**: Connecting bridge diameter (mm) **Example**: W-Type, OD=20mm, HZ=250mm, CZ=350mm, OL=625mm, A=52mm, Resistance=0.9Ω, marked as: W-Type/20/250/625/52/0.9Ω ![w type sic heating element drawing](https://cvsicelement.com/wp-content/uploads/2025/08/W-Type-SiC-Heating-Element-Drawing-e1754361105313.webp) *Note*: Contact us for other specifications or customization. ### Installation Instructions To ensure the performance and safety of W-Type Silicon Carbide Heating Elements, follow these installation steps: - **Inspect Element**: Check for cracks or damage before installation. - **Installation Position**: Cold ends form a right-angle structure with the hot zone, ideal for furnace roof or side installation in space-constrained or single-side wiring furnaces. - **Fixing Device**: Use ceramic clamps or dedicated clamping devices to avoid direct contact with metal. - **Power Connection**: Compatible with 110-480V three-phase power, ensure resistance matching, and use an SCR regulator for precise temperature control. - **Ventilation**: Keep the installation area well-ventilated to prevent localized overheating. - **Preheating**: Gradually increase power during initial use to avoid thermal shock. - **Regular Maintenance**: Inspect wiring and clamping devices to ensure they are secure and free from looseness or corrosion. *Note*: Professionals should perform installation; contact us for detailed guidance. ### Application Fields CVSIC W-Type Silicon Carbide Heating Elements are designed for three-phase power high-temperature kilns, widely used in: - **Float Glass Production**: Manufacturing soda-lime flat glass in float glass production lines for construction, automotive, and solar glass. - **High-Temperature Industrial Kilns**: Supporting ceramic sintering, metal heat treatment, and other high-uniformity heating needs. - **Special Furnace Types**: Ideal for space-constrained or single-side wiring furnaces, such as tunnel kilns and shuttle kilns. ### Product Advantages - **Three-Phase Power Optimization**: W-Type design built for three-phase power, delivering efficient and steady heat. - **Energy-Saving and Durable**: High-purity SiC material, resistant to thermal shock and oxidation, extending lifespan and cutting energy costs. - **Flexible Installation**: Right-angle cold-end structure, perfect for roof or side installation in tight spaces. - **Excellent Thermal Uniformity**: Three heating units enable multi-zone temperature control, improving furnace temperature consistency. - **Global Support**: Backed by overseas service centers for fast response and technical guidance. ### Design Recommendations To optimize the performance of W-Type Silicon Carbide Heating Elements, follow these suggestions: - **Hot Zone Length**: Match the hot zone length to the furnace chamber width to avoid insertion into the furnace wall, preventing ablation. - **Cold Zone Length**: The cold zone length should match the furnace wall thickness plus an extra 50-150mm for connecting accessories. - **Furnace Aperture**: The furnace aperture should be 1.4-1.6 times the cold end diameter to allow free expansion and prevent breakage. - **Spacing Design**: Keep a distance of ≥3 times the outer diameter between the element and materials or furnace walls and ≥4 times the outer diameter between element centers for optimal heat distribution. - **Multi-Zone Layout**: For wide or tall furnaces, arrange W-Type elements along one side with zoned temperature control to improve uniformity. - **Temperature Control System**: Pair with a PID controller for precise temperature control, thereby extending the lifespan of the element. ### Customization Services CVSIC offers flexible customization for W-Type Silicon Carbide Heating Elements: - **Size Customization**: Adjust outer diameter, hot/cold zone lengths, shank spacing, and connecting bridge diameter to fit your furnace design. - **Resistance Optimization**: Customize resistance to match three-phase power configurations. - **Special Coatings**: Provide anti-oxidation or corrosion-resistant coatings for harsh environments. - **Bulk Supply**: Support large-scale wholesale with fast delivery and consistent quality. - **Technical Support**: Offer engineer guidance and heat distribution analysis from selection to installation.
