This dual-purpose design makes it an indispensable tool for research environments that require both extreme heat and the flexibility of a modular tube setup, ensuring that complex experimental configurations can be managed with ease and efficiency.
Primarily utilized within material science departments, industrial R&D centers, and semiconductor fabrication labs, this unit excels in sophisticated thermal treatments such as Chemical Vapor Deposition (CVD), crystal growth, and advanced ceramic sintering. The system's ability to maintain a 1400 mm heating length allows for high-throughput processing or the creation of precise thermal gradients. Its robust construction is tailored for demanding industries including aerospace, energy storage, and electronics, where material purity and thermal consistency are critical to the success of the end product.
Engineered for long-term reliability in rigorous operating conditions, this system utilizes premium grade MoSi2 heating elements and a double-layer mild steel casing. The inclusion of integrated cooling fans ensures the exterior surface remains at a safe operating temperature, protecting both the operator and surrounding lab infrastructure. With six individual PID controllers providing granular management of the thermal profile, the equipment offers researchers the confidence that their most sensitive processes will be executed with repeatable, high-fidelity results every time.
Key Features
- Six Independent Heating Zones: The furnace is equipped with six distinct heating zones (200, 200, 300, 300, 200, and 200 mm) each controlled by an individual PID unit, allowing for the creation of precise thermal gradients up to 10°C/cm.
- Advanced Split-Body Design: The split-chamber architecture allows for easy insertion and removal of the processing tube, which is essential for pre-assembled experimental rigs or for rapid cooling between process cycles.
- High-Purity Alumina Processing Tube: A Ø60 mm x 1800 mm alumina tube provides superior chemical resistance and structural integrity at extreme temperatures, ensuring a clean environment for sensitive material synthesis.
- MoSi2 Heating Elements: Utilizing 1800°C grade Molybdenum Disilicide elements, the system achieves rapid heat-up times and sustained high-temperature performance without the degradation common in lower-tier heating components.
- Water-Cooled Vacuum Flanges: The system includes a comprehensive set of water-cooled flanges that maintain seal integrity even at maximum operating temperatures, facilitating high-vacuum processes down to the levels required for thin-film deposition.
- Precision PID Temperature Control: Each of the six controllers offers 50 programmable segments, providing a resolution of 0.3°C and an accuracy of ±1°C to meet the most stringent laboratory standards.
- Enhanced Safety Interlocks: Built-in overheating and broken thermocouple alarms provide automatic shut-off capabilities, protecting the equipment and the process tube from thermal runaway or hardware failure.
- Integrated Data Acquisition: With RS485 serial communication and LabVIEW-based software, users can remotely monitor temperature profiles, log data, and manage complex recipes from a central workstation.
- Thermal Efficiency Construction: A double-layer steel case with forced air cooling keeps the external shell temperature below 70°C, minimizing the heat load on the laboratory environment and improving energy efficiency.
- Comprehensive Uniformity: The unit provides a uniform temperature zone of 1000 mm at ± 5°C when all zones are synchronized, ideal for large-batch processing or long sample sintering.
