Three-zone and three-phase horizontal tube furnaces are designed for precise thermal processing with segmented temperature control. Key specifications include temperature ranges up to 1800°C, customizable tube diameters (2.5–4 inches), and lengths up to 27 inches. These models feature advanced gas circulation systems, multi-zone heating for uniform heat distribution, and compatibility with materials like alumina or quartz tubes. Industrial-grade control systems enable remote monitoring and reduce operational errors. Below is a detailed breakdown of their capabilities and configurations.
Key Points Explained:
1. Model Variants and Core Specifications
- 575H14HT:
- Max temperature: 1400°C (2552°F)
- Tube dimensions: Up to 4" diameter × 16–17" length (expandable)
- 3H14HT2.5x27:
- Max temperature: 1400°C
- Fixed dimensions: 2.5" diameter × 27" length
- 3H18-40HT2.5x27:
- Max temperature: 1760°C (3272°F)
- Same dimensions as above; upgradable to 4" diameter
2. Multi-Zone Temperature Control
- Each zone (1–3) independently reaches:
- 1200°C, 1400°C, or 1700°C (selectable per model)
- Enables gradient heating for processes like annealing or CVD.
3. Tube Materials and Customization
- Standard options: Alumina, Pyrex, fused quartz (for non-corrosive environments).
- Corrosive-resistant: Molybdenum or tungsten tubes.
- Note: Tubes are purchased separately; not included with the furnace.
4. Advanced Operational Features
- Gas circulation: Supports inert (Ar/N₂), reducing (H₂), or oxidizing (O₂) atmospheres.
- Control systems: Remote monitoring, programmable profiles, and error reduction for industrial use.
5. Industrial Adaptability
- Rotary models: Optional customization for:
- Rotation rate, inclination angle, and powder feed rate.
- Temperature profiles up to 1700°C.
- Bottom lifting furnace: Enhances loading/unloading efficiency for heavy or sensitive samples [/topic/bottom-lifting-furnace].
6. Safety and Efficiency
- Multi-zone designs minimize thermal stress on materials.
- Automated controls reduce manual intervention, critical for high-throughput labs.
For purchasers, prioritize models aligning with both temperature needs and tube compatibility—especially for corrosive applications. Upgradable diameters (e.g., 2.5" to 4") offer future flexibility.
