Six Zone Split Tube Furnace 1.8 Meter Quartz Tube 1200C High Temperature Heating System

Product Overview

This six-zone ultra-long split tube furnace represents a pinnacle in thermal processing engineering, specifically designed for high-precision material research and industrial production. By integrating six independently controlled heating zones across a massive 1.8-meter heated length, this system allows operators to establish either an exceptionally long constant temperature zone or complex, multi-step thermal gradients. Its split-hinge design is engineered for rapid access, enabling the easy insertion of process tubes and the assembly of intricate experimental configurations without long downtime or labor-intensive teardowns.

Primary applications for this equipment span across semiconductor wafer processing, chemical vapor deposition (CVD), and advanced ceramic sintering where temperature uniformity and atmosphere control are critical. The system provides a robust platform for target industries including aerospace, energy storage, and metallurgy. Whether utilized for annealing ultra-long wire samples or conducting zone refining, the furnace delivers the consistency and scalability required for transition from laboratory-scale experiments to pilot-plant production environments.

Built with professional-grade components and a double-layer steel housing, the unit is intended for continuous, heavy-duty operation in demanding industrial R&D settings. The separation of the heating chamber from the control electronics ensures long-term reliability and protects sensitive components from thermal stress. This equipment is the preferred choice for facilities prioritizing high-throughput processing, precision thermal profiling, and the ability to maintain high vacuum or specific gas atmospheres under rigorous duty cycles.

Key Features

• Six Independent Heating Zones: Each of the six 300 mm heating zones is driven by its own dedicated control system, allowing for the creation of intricate temperature profiles or a massive 1525 mm constant temperature zone within +/- 2ºC accuracy.
• Precision PID Temperature Control: Six 30-segment programmable digital controllers provide meticulous management of heating rates, cooling rates, and dwell times, ensuring repeatable results for sensitive metallurgical processes.
• Ultra-Long Heating Chamber: With a total heated length of 1800 mm (72"), this system accommodates long process tubes and large-batch samples, significantly increasing throughput compared to standard laboratory furnaces.
• Split-Hinge Design: The furnace body is split lengthwise and supported by gas springs, allowing for easy tube replacement, fast cooling cycles, and visual inspection of the tube setup without disturbing the internal atmosphere.
• High-Purity Alumina Insulation: Advanced fibrous alumina insulation minimizes heat loss and reduces energy consumption, while the double-layer steel case with cooling fans maintains a safe exterior touch temperature during operation.
• Advanced Heating Elements: Utilizing 1300ºC grade Fe-Cr-Al alloy doped with Molybdenum, the system ensures rapid heating times up to 1200ºC and excellent oxidation resistance for a longer service life.
• PC-Link Communication Interface: Equipped with an RS485 communication port and specialized control software, the system enables remote monitoring and control from a PC, facilitating data logging and complex process automation.
• Vacuum and Atmosphere Versatility: The equipment includes high-quality stainless steel vacuum flanges with needle valves and pressure gauges, supporting processing under vacuum levels or controlled gas environments like Nitrogen, Argon, or forming gas.
• Integrated Safety Protections: Built-in safeguards include overheating alarms, broken thermocouple protection, and over-temperature shut-off mechanisms to protect both the equipment and the processed materials.
• Customizable Tube Diameters: While provided with a 4" OD quartz tube, the flexible design can accommodate various processing tubes from 1" to 4" O.D., allowing the furnace to adapt to evolving research requirements.
