1100C Dual Zone Hydrogen Gas Tube Furnace with Quartz Tube and Integrated H2 Leak Detection System

Product Overview

This high-temperature dual-zone thermal processing system is engineered specifically for the heat treatment of oxidation-sensitive materials within a controlled hydrogen atmosphere. By integrating a sophisticated dual-heating zone configuration, the equipment provides researchers and industrial engineers with the flexibility to create either a steep temperature gradient or an exceptionally wide zone of thermal uniformity. This capability is critical for complex material syntheses where precise thermal stages are required for phase transitions or chemical vapor deposition processes. The unit is designed to operate continuously at 1100°C, with the capability to reach 1200°C for shorter intervals, making it a versatile workhorse for advanced material science laboratories.

Targeted primarily at sectors such as semiconductor manufacturing, catalyst research, and advanced metallurgy, the system excels in environments where atmospheric purity and safety are paramount. It serves as an essential tool for processes involving the structural ordering and graphitization of nitrogen-doped carbon, as well as the reduction of metal oxides. The equipment is constructed to withstand the rigors of industrial R&D, utilizing a double-layer steel casing with integrated air cooling to maintain low external surface temperatures even during peak operation. This focus on both performance and operator safety ensures that the equipment remains a reliable asset in demanding laboratory settings.

Confidence in this system is built upon its multi-layered safety architecture and precision engineering. From the automated hydrogen gas shutdown protocols to the robust quartz chamber construction, every component is selected to ensure consistent results and operational longevity. The equipment provides a stable, repeatable environment for thermal processing, allowing users to focus on experimental outcomes rather than hardware reliability. Whether performing routine annealing or pioneering new material synthesis, this unit delivers the robustness and precision required for high-stakes industrial and scientific research.

Key Features

• Dual-Zone Thermal Management: The system features two independently controlled 200 mm heating zones, providing a total 400 mm heating area. This allows for the creation of customized thermal profiles, including a 250 mm stable uniformity zone when both zones are synchronized, or a distinct thermal gradient for specific material transport requirements.
• Integrated Honeywell Hydrogen Safety System: For maximum operational security, a UL-approved gas detector is integrated into the control loop. Upon detecting hydrogen levels at 10% LEL, the system automatically triggers a solenoid valve to isolate the gas supply and cuts power to the heating elements, preventing hazardous accumulation.
• Precision PID Control and Automation: The built-in PID auto-tune controller offers sophisticated programming with over-temperature and broken thermocouple protection. It ensures less than 1°C of temperature fluctuation during dwelling periods, providing the high-level stability required for sensitive industrial processes.
• Advanced Gas Delivery and Exhaust: The unit includes separate delivery lines for inert and hydrogen gases, each equipped with mechanical needle valves for fine-tuning flow rates. A specialized stainless steel torch is installed at the exhaust end to safely burn off hydrogen, preventing atmospheric contamination in the laboratory.
• High-Purity Quartz Process Chamber: Utilizing premium fused quartz tubes in either 60mm or 80mm diameters, the furnace maintains a clean, chemically inert environment. The quartz's transparency allows for visual monitoring of the process, while its thermal shock resistance ensures durability through repeated heating and cooling cycles.
• Robust Safety Enclosure: Beyond the gas detection, the equipment is fitted with specialized flange fixtures and tube covers that provide a physical barrier in case of emergency. The double-layered steel casing ensures the exterior remains safe to touch, even when internal temperatures reach 1100°C.
• Customizable Communication Options: To support digital workflows, the control system can be upgraded with a PC communication module. This allows for remote monitoring, data logging, and sophisticated recipe management from a workstation or laptop.
• Optimized Thermal Insulation: High-quality fibrous ceramic tube blocks are utilized to minimize heat radiation loss and protect the vacuum flanges. This engineering choice improves energy efficiency and protects the integrity of the seals and fittings during long-duration runs.
