Maximum Durability and Thermal Efficiency for High Temperature Industrial Furnaces
Silicon Carbide (SiC) heating elements are non-metallic high-temperature electric heating elements manufactured from high-purity recrystallized silicon carbide crystals. Operating efficiently between 1400°C and 1600°C, they offer superior surface load resistance, outstanding oxidation stability, and chemical neutrality. They are ideal for aluminum melting/holding furnaces, ceramic sintering, glass processing, and metallurgical heat treatment applications.
Key Benefits
- High Operating Temperature up to 1600°C: Provides continuous, stable, and uniform heat radiation under demanding industrial furnace conditions.
- Low Energy Loss (Cold Zone Technology): Features low-resistance metallized aluminum spray terminal ends (CZ - Cold Zone) to prevent heat leakage through furnace insulation and avoid terminal overheating.
- Rapid Heat-Up & High Power Density: Achieves target operating temperatures quickly, optimizing furnace cycle times.
- Atmospheric and Corrosion Resistance: Delivers extended service life in oxidizing and protective atmosphere environments. Fully compatible with SCR thyristor power control units.
Available Geometries & Configurations
- Straight / Rod Type (ED / GD): Standard double-ended elements for through-wall installations.
- U-Type (GDU): Single-ended terminal design allowing straightforward vertical or horizontal insertion through furnace walls/roofs.
- Three-Phase / W-Type (GDS): Multi-leg design engineered for direct three-phase star (Y) or delta (Δ) connections.
- Spiral Tubular Type (SC / SCR): Single or double helical cut tubular design delivering higher electrical resistance in compact furnace chambers.
- Dumbbell / Thick End Type (GC-DB): Enlarged terminals designed for reduced connection heat dissipation.
