1200C Max Three Zone Tube Furnace 6 Inch OD Max with Tube and Flange

Product Overview

This high-performance thermal processing system is designed to meet the rigorous demands of material science research and industrial production. Featuring a three-zone heating configuration and a generous 150 mm (6") outer diameter capacity, the equipment provides a versatile platform for large-scale sample processing, including 4-inch wafer annealing. By utilizing three independently controlled heating zones, users can achieve exceptional temperature uniformity or create precise thermal gradients, making this unit an indispensable tool for complex heat treatment cycles that require strict atmospheric control and thermal stability.

The system is engineered for a wide array of applications across the semiconductor, aerospace, and advanced ceramics industries. Whether it is used for chemical vapor deposition (CVD), sintering of high-purity materials, or the controlled oxidation of metal components, the equipment delivers repeatable and reliable results. Its robust construction and sophisticated control interface allow for seamless integration into R&D laboratories and pilot production lines where precision and scalability are paramount for developing the next generation of high-temperature materials.

Built with long-term operational reliability in mind, this furnace utilizes premium grade insulation and advanced power management to maintain consistent performance under demanding conditions. The integration of high-purity alumina fibrous insulation ensures thermal efficiency while minimizing heat loss, resulting in a system that is both energy-efficient and highly responsive to temperature adjustments. Laboratory managers and procurement teams can rely on this equipment to provide a stable thermal environment, ensuring that critical experiments and production batches are protected from thermal fluctuations and contamination.

Key Features

• Three-Zone Independent Control: The system features three distinct heating zones that allow for the creation of an extended uniform temperature area or a custom thermal gradient. This configuration is essential for processes requiring specific temperature profiles across the length of the processing tube, such as crystal growth or large-batch annealing.
• Advanced Touch Screen Interface: A 7-inch high-resolution touch panel provides an intuitive control hub for the entire system. Users can benefit from one-click start/stop functionality, real-time data monitoring, and the ability to pre-store multiple complex temperature programs, significantly reducing the potential for manual setup errors.
• Precision PID Temperature Regulation: Equipped with a sophisticated PID controller and auto-tune functions, the unit maintains a temperature accuracy of +/- 0.2 °C. This level of precision is critical for sensitive material processing where even minor deviations can impact the structural integrity or electrical properties of the sample.
• High-Purity Al2O3 Fibrous Insulation: The furnace chamber is lined with energy-saving high-purity alumina fibrous insulation, further enhanced by an aluminum oxide coating. This combination not only extends the lifespan of the heating elements but also ensures rapid heating rates and superior thermal containment.
• Large Diameter Processing Capability: Designed to accommodate quartz tubes up to 150 mm (6") in diameter, this system is ideal for 4-inch wafer processing and larger bulk material samples. The flexibility to use various tube diameters (80mm to 150mm) via adapters makes it a highly adaptable asset for evolving research needs.
• Comprehensive Data Logging: The integrated control system automatically records process data, storing history for up to one month. This feature facilitates thorough post-process analysis and quality control documentation, which is vital for industrial certifications and research reproducibility.
• Robust Vacuum and Atmosphere Sealing: High-quality stainless steel sealing flanges are available to support processing under vacuum or controlled gas environments. This allows the equipment to handle diverse chemistries and prevent oxidation during high-temperature cycles.
• Safety-First Engineering: Built-in protection mechanisms for overheating and thermocouple failure come standard, providing peace of mind during long-duration runs. The system's design emphasizes safe operation with specific protocols for pressure management and gas flow regulation.
• Solid Tube Insulation Performance: The solid tube insulation design provides a more uniform temperature zone compared to standard split-tube designs, ensuring that the radiant heat is distributed evenly around the entire circumference of the processing tube.
• Programmable Segment Flexibility: With 50 programmable segments, the system supports highly complex heating and cooling ramps. This allows for precise simulation of industrial thermal cycles and the ability to perform slow, controlled cooling to prevent thermal shock in brittle materials.
