Core Structure & Key Properties
- Structure Composition: Ceramic tube (alumina/zirconia material) + heating coil + lead wire + insulation layer.
- Critical Performance Traits:
- Rapid heating & high efficiency: Fast thermal response, heat conversion rate up to 90%+, saves energy consumption.
- Wide temperature range: Operating temperature 200–1200℃ (special formulations up to 1600℃), adaptable to diverse heating needs.
- Excellent corrosion/oxidation resistance: Ceramic tube resists high-temperature oxidation and corrosive gas erosion.
- Safe & stable: Insulating ceramic shell prevents electric leakage, stable performance under long-term operation.
- Compact design: Small volume, easy to install in limited spaces, suitable for localized heating.
Typical Applications
- Industrial manufacturing: Plastic molding, metal heat treatment, glass processing, and semiconductor wafer heating.
- Commercial & household: Small appliances (electric stoves, toasters), laboratory equipment, and food drying machines.
- Special environments: High-temperature ovens, kilns, and corrosive industrial workshops (chemical, electroplating industries).
- Agricultural use: Greenhouse heating, seedling cultivation temperature control.
Customization & Technical Specifications
- Size options: Diameter 6–25mm, length 50–1500mm (customizable for special requirements).
- Power range: 50W–2000W, single-ended or double-ended wiring designs.
- Ceramic tube material: High-purity alumina (cost-effective, for ≤1200℃) or zirconia (high-temperature resistant, for ≥1200℃).
- Additional features: Optional temperature sensors, waterproof coatings, or anti-corrosion surface treatments.
