Three Zone Heating Split Vertical Tube Furnace 1700 High Temperature Vacuum Atmosphere Thermal Process System

Product Overview

This high-performance thermal processing system represents a pinnacle in material science research and industrial heat treatment. Engineered as a vertical, split-able tube furnace with three independent heating zones, the equipment is designed to meet the rigorous demands of researchers working up to 1700°C. Its vertical orientation and split-clamshell design provide unmatched versatility, particularly for setups requiring rapid quenching or the integration of complex vertical motion mechanisms. The system provides a stable environment for sample heating under high vacuum or precisely controlled flowing gas conditions, ensuring it is a cornerstone tool for developing next-generation materials.

Targeted at advanced laboratories, semiconductor manufacturers, and metallurgical research facilities, this unit delivers the precision required for single crystal growth, thin-film deposition, and homogenization processes. By leveraging three independent heating zones, the system overcomes the thermal limitations of single-zone furnaces, allowing for a significantly expanded constant temperature region. This ensures that experimental samples, regardless of their size or position within the heating chamber, receive uniform thermal energy, which is critical for the reproducibility of scientific data in high-stakes R&D environments.

B2B industrial buyers can depend on this system's robust construction and engineering excellence. Built with high-purity alumina fiber insulation and a double-layer cooling shell, the equipment maintains operational integrity and external safety even during continuous 1600°C high-temperature cycles. The integration of precision PID controllers and advanced safety alarms ensures that once a cycle is programmed, the system operates with minimal oversight, providing the reliability and long-term consistency required for demanding industrial schedules and critical material processing.

Key Features

• Three-Zone Independent Thermal Control: Each 200mm heating zone is managed by an independent PID controller, allowing for the creation of an elongated uniform temperature profile or a precise thermal gradient depending on the process requirements.
• Precision Split-Kernel Design: The vertical furnace body is hinged to facilitate easy opening, allowing for rapid tube access, simplified sample loading, and the ability to exchange process tubes without disturbing complex vertical lifting or quenching mechanisms.
• Advanced High-Purity Alumina Fiber Insulation: This system utilizes energy-efficient, grade-A alumina fiber that minimizes heat loss, reduces power consumption, and ensures rapid heat-up times while protecting the structural integrity of the furnace.
• High-Vacuum Integrated Sealing: Equipped with stainless steel vacuum sealing flanges, valves, and gauges, the unit can reach vacuum levels of 10E-5 Torr when paired with a molecular pump, making it ideal for contamination-sensitive processes.
• Programmable PID Automation: The control system features 30-segment programmable logic for precise management of heating rates, dwell times, and cooling curves, ensuring consistent results across multiple batches.
• Safety-First Double-Layer Cooling Shell: An integrated air-cooling system between the inner and outer shells keeps the furnace exterior at a safe temperature, protecting personnel and enhancing the lifespan of the internal electronics.
• Platinum-Rhodium Thermocouple Accuracy: Utilizing B-type double platinum-rhodium thermocouples, the unit provides high-accuracy temperature feedback and long-term stability even under continuous extreme heat.
• Integrated Safety Protections: Built-in mechanisms for overheating and broken thermocouple detection automatically halt power to prevent equipment damage, ensuring safe operation during unattended long-term heating cycles.
• Vertical Quenching Compatibility: The vertical orientation is specifically designed to facilitate quenching experiments, where samples can be dropped or lowered from the hot zone into a cooling medium via an optional lifting mechanism.
