Four Zone Tube Furnace 1100C with 600mm Large Diameter Quartz Tube and Vacuum Flanges

Product Overview

This high-performance four-zone tube furnace represents a pinnacle in thermal processing engineering, specifically designed to accommodate large-scale material samples and 8-inch wafers. By utilizing a massive 600mm (24") diameter high-purity quartz tube, the system provides an expansive environment for specialized heat treatments that require both volume and precision. The core value of this equipment lies in its multi-zone configuration, which allows for intricate control over thermal gradients, making it an indispensable tool for advanced chemical vapor deposition (CVD), annealing, and sintering processes where uniformity is paramount.

Targeted at industrial R&D centers and material science laboratories, this equipment excels in handling diverse atmospheric conditions. Whether operating under a high vacuum or specific protective gas environments, the system maintains its integrity through robust engineering. The dual-layer steel casing with integrated air cooling ensures that while the internal chamber reaches high temperatures, the external surface remains safe for operators, facilitating a productive and secure laboratory environment. This unit is optimized for the synthesis of new materials, offering researchers the flexibility to simulate complex industrial manufacturing conditions at a bench-scale or pilot-scale level.

Reliability is at the forefront of this design, featuring a refractory fibrous alumina insulation liner that maximizes energy efficiency and thermal stability. The system is built to withstand demanding industrial duty cycles, providing consistent performance across thousands of hours of operation. With its ability to handle structural ordering and graphitization of advanced carbon materials, the equipment serves as a dependable backbone for projects involving catalyst development, semiconductor research, and metallurgical testing. This system is not merely a furnace but a comprehensive thermal solution for high-stakes material innovation.

Key Features

• Four-Zone Independent Temperature Management: The system features four distinct heating zones, each 300 mm in length, providing a total heated length of 1200 mm. This configuration allows for the creation of precise thermal gradients or an exceptionally long constant temperature zone of up to 1100 mm, ensuring unmatched processing flexibility for long substrates or high-volume batches.
• Extra-Large Diameter Quartz Processing Tube: Equipped with a 600 mm (24") OD high-purity quartz tube, this unit is specifically designed for processing large-format materials, such as 8-inch wafers. The quartz material provides excellent thermal shock resistance and chemical inertness, maintaining a contamination-free environment for high-purity sintering and annealing.
• Precision Microprocessor PID Control: Each zone is governed by a dedicated digital controller featuring 30-segment programmable cycles and self-tuning functions. The microprocessor-based PID logic prevents temperature overshooting and maintains a steady-state accuracy of ±1°C, which is critical for sensitive material transformations and repeatable results.
• Advanced Multi-Stage Vacuum Sealing: The system includes a pair of water-cooled stainless steel hinged flanges designed for rapid access and superior sealing. Utilizing silicon O-rings and integrated KF40 ports, the furnace can achieve vacuum levels as low as 10-5 torr when paired with secondary turbomolecular pumps, facilitating ultra-clean processing conditions.
• Industrial-Grade Heating Elements: Utilizing high-quality NiCrAl resistance wire heating elements, the furnace achieves a maximum heating temperature of 1150°C. These elements are chosen for their durability and consistent heat release, ensuring long-term reliability even when subjected to frequent thermal cycling.
• Integrated Safety and Cooling Systems: The double-layer steel casing is engineered with internal air cooling to keep the external surface temperature below 70°C. This design protects laboratory personnel and prevents ambient heat buildup, while the inclusion of a recirculating water chiller for the flanges protects seals during high-temperature runs.
• Comprehensive Monitoring and Calibration: The unit is equipped with four K-type thermocouples for real-time monitoring of each zone. The flanges include specialized ports for secondary calibration thermocouples, allowing users to verify internal temperatures and ensure the highest standards of process validation and quality control.
• High-Efficiency Refractory Insulation: High-quality fibrous alumina insulation liners minimize heat loss and power consumption. This energy-efficient design combined with ceramic tube blocks effectively contains radiation, focusing thermal energy into the processing zone rather than the surrounding environment.
