Four Zone 1200C Multi Zone Split Tube Furnace with Independent Digital Temperature Controllers for One or Two Inch Processing Tubes

Product Overview

This precision-engineered multi-zone heating system provides sophisticated thermal processing capabilities for advanced material science and industrial research and development. Designed as a four-zone split tube furnace, the equipment allows for the creation of precise step thermal gradients or exceptionally long uniform temperature zones by independently adjusting the thermal output of four distinct 100mm segments. The separate temperature control console ensures that electronic components are shielded from radiant heat, enhancing the long-term reliability and operational stability of the entire system during high-temperature cycles up to 1200°C.

Ideal for Vapor Phase Transport (VPT), Chemical Vapor Deposition (CVD), and Physical Vapor Transport (PVT), this unit offers researchers the flexibility to accommodate processing tubes with outside diameters of one or two inches. Its split-hinge design facilitates easy sample loading/unloading and enables rapid cooling, which is essential for certain metallurgical and thin-film growth processes. By integrating high-purity alumina fiber insulation and advanced heating elements, the system achieves remarkable energy efficiency while maintaining a cool exterior surface temperature for operator safety.

Built for demanding laboratory environments, the equipment emphasizes consistency and reproducibility. Each of the four zones is governed by its own dedicated digital controller, allowing for complex temperature profiles that are essential for growing high-quality crystals and synthesizing novel materials. Whether used in a horizontal configuration for standard processing or mounted vertically for specialized applications, the unit delivers the robustness and precision required for critical industrial research and high-stakes material characterization.

Key Features

• Independently Controlled Four-Zone Heating: The system features four separate 100mm heating zones, each equipped with its own dedicated PID controller. This architecture allows users to establish specific temperature gradients or extend the constant temperature zone to up to 250mm with ±1°C accuracy.
• Advanced Thermal Insulation and Shell Design: A double-layered steel case integrated with air-cooling technology maintains the exterior surface temperature below 60°C. The internal chamber utilizes energy-saving, high-purity fibrous alumina insulation that minimizes heat loss and improves temperature response times.
• High-Performance Alloy Heating Elements: Equipped with 1300°C grade Fe-Cr-Al alloy elements doped with Molybdenum, the furnace ensures long-lasting operation and can reach peak temperatures of 1200°C with rapid heating rates of up to 20°C per minute.
• Precision PID Digital Controllers: The control console includes four individual digital units featuring PID automatic control for heating, cooling, and dwell times. Each controller supports up to 30 programmable segments, providing granular control over complex thermal sequences.
• Split Furnace Architecture: The split-hinge design allows for the rapid opening of the furnace, which is critical for experimental setups requiring quick access to the processing tube or for accelerating cooling rates to quench materials after high-temperature treatment.
• Versatile Mounting Configurations: The heating module is engineered for flexibility, capable of being positioned horizontally or vertically depending on the specific experimental requirements, such as vertical Bridgman crystal growth or horizontal CVD processes.
• Integrated Safety and Monitoring: Built-in protection against overheating and broken thermocouples ensures the system shuts down safely in the event of a fault, protecting both the equipment and the sensitive samples within the processing tube.
• Scalable Communication Interfaces: Standard RS485 communication ports allow for potential integration with external PC software for remote monitoring, data logging, and complex program synchronization across all heating zones.
