12 Zone Ultra Long Split Tube Furnace with 20 Foot Quartz Tube and 1100C Max Temperature

Product Overview

This sophisticated thermal processing system is engineered for large-scale research and industrial applications requiring extreme heating lengths and precise atmosphere control. By integrating twelve independent heating zones over a total length of six meters, the equipment provides researchers with the unique ability to create complex thermal gradients or maintain an exceptionally long constant temperature zone. This system is specifically designed to accommodate long strip samples, wires, or high-volume material batches that conventional laboratory furnaces cannot handle. Its split-hinge architecture ensures that the installation and maintenance of the ultra-long process tube are straightforward, reducing the risk of component damage during setup.

Targeted at advanced material science, metallurgy, and semiconductor industries, the equipment serves as a cornerstone for processes such as chemical vapor deposition (CVD), annealing of superconducting wires, and the synthesis of specialized carbon structures. The unit bridges the gap between small-scale laboratory experimentation and industrial-scale production, offering the precision of a research tool with the throughput capabilities of a pilot-plant system. Built with heavy-duty industrial components, the furnace is optimized for continuous operation, providing high-purity environments through its integrated vacuum-sealed quartz tube and stainless steel flange system.

Reliability is the hallmark of this thermal unit. Every component, from the high-purity fibrous alumina insulation to the modular steel casing, is selected to withstand the rigors of high-temperature thermal cycling. The separation of the control electronics into a dedicated cabinet protects sensitive PID controllers from thermal stress, ensuring long-term operational stability. Buyers can invest with confidence, knowing this system delivers repeatable results, uniform heat distribution, and robust performance under vacuum or controlled atmospheric conditions, making it an indispensable asset for demanding industrial R&D environments.

Key Features

• Twelve Independent Heating Zones: Each of the 500 mm zones is equipped with its own dedicated PID controller and thermocouple, allowing for unmatched control over the thermal profile across the entire 6000 mm length.
• Split-Hinge Furnace Architecture: The heating chamber opens lengthwise, facilitating the easy loading and unloading of the ultra-long process tube and allowing for rapid cooling or inspection of the sample setup without disassembly.
• Modular Chamber Construction: Engineered for logistical efficiency, the furnace utilizes a modulated chamber design that enables the ultra-long system to be shipped in sections and assembled on-site with ease.
• Advanced Touch Screen Control: A centralized touch screen interface manages all twelve zones simultaneously, providing a user-friendly platform for editing temperature profiles and monitoring real-time data from a single point.
• High-Purity Fibrous Alumina Insulation: The chamber is lined with energy-efficient alumina fiber, which offers superior thermal insulation, low heat storage, and excellent resistance to thermal shock.
• Precision Vacuum Flange System: Includes stainless steel quick-assembling flanges with needle valves and pressure gauges, designed to maintain high-vacuum levels or precise gas atmospheres throughout the heating cycle.
• Enhanced Heating Elements: Utilizing 1300°C grade Fe-Cr-Al alloy elements doped with Molybdenum, the system ensures rapid heating rates up to 20°C/min and extended service life at high temperatures.
• Remote PC Interface Capability: Built-in RS485 communication ports and specialized software allow for complete remote operation, data logging, and recipe management from a secure distance.
• Integrated Safety Protections: The system features built-in overheating protection and broken thermocouple alarms, automatically shutting down power to protect the equipment and samples in the event of a fault.
• Double-Layer Steel Casing: A rugged, air-cooled double-shell structure keeps the external surface temperatures safe for operators while maintaining the structural integrity of the 20-foot frame.
