1500C Max Dual Zone Rotary Tube Furnace with 60 mm OD Alumina Tube for High Temperature Material Synthesis

Product Overview

This high-temperature rotary thermal processing system is engineered for the precision synthesis of inorganic compounds, providing unparalleled thermal uniformity at temperatures reaching up to 1500ºC. By combining rotary motion with dual-zone heating, the equipment ensures that precursor materials are subjected to consistent thermal profiles, which is critical for achieving high-quality phase purity and uniform particle size in advanced material R&D. The system provides a robust platform for researchers and industrial engineers who require a reliable, high-vacuum environment for demanding thermal treatments.

Designed primarily for material science laboratories and industrial research facilities, this unit excels in applications ranging from the calcination of battery cathode materials to the synthesis of specialized ceramics and metallic powders. The rotary design facilitates the continuous mixing of powder samples, preventing material agglomeration and ensuring that every particle is exposed to the same atmosphere and temperature throughout the cycle. This makes it an essential tool for scaling up laboratory results to pilot-scale production yields of up to 2 kg per batch.

Built with long-term reliability in mind, this furnace utilizes a double-shell casing and multi-fan cooling system to maintain a safe exterior temperature even during prolonged high-temperature operations. The internal high-purity alumina fibrous insulation is selected for its superior energy-saving properties and low thermal mass, allowing for rapid heating and cooling cycles. Professionals can trust this system for repeatable results in atmosphere-controlled or vacuum-driven processes, knowing that the structural integrity and precision control logic are optimized for the most demanding industrial environments.

Key Features

• Precision Dual-Zone Thermal Control: The equipment features two independently controlled heating zones, each 195 mm in length, which can be synchronized to create an extended constant temperature zone of 250 mm. This architecture allows for the creation of precise thermal gradients or a highly stable uniform plateau, depending on the specific requirements of the synthesis process.

• Dynamic Rotary and Tilt Mechanism: To optimize material throughput and agitation, this unit provides a variable rotation speed from 0 to 7 RPM and a furnace tilt angle adjustable from -5° to 20°. This combination allows for fine-tuning the residence time of the material within the hot zone, which is vital for continuous or batch powder processing.

• High-Performance Silicon Carbide Heating: Equipped with 16 high-grade SiC heating elements, the system achieves rapid ramp rates and stable high-temperature performance. For specialized applications requiring even higher thermal thresholds, the heating elements can be upgraded to support operations up to 1600ºC, ensuring future-proof versatility for evolving research needs.

• Advanced Splittable Furnace Body: The split-cover design is a hallmark of engineering excellence, enabling the user to open the furnace for faster cooling of the processing tube or for easy maintenance and inspection of the heating elements. This feature significantly reduces downtime between batches and facilitates the quick removal or insertion of the alumina processing tube.

• Vacuum-Ready Alumina Processing Chamber: The system includes a high-purity 60 mm OD alumina processing tube supported by stainless steel sealing flanges with needle valves. This configuration supports high-vacuum levels down to 4.5x10-2 torr, allowing for sensitive material processing under inert atmospheres or controlled vacuum conditions to prevent oxidation.

• Intelligent PID Digital Regulation: Each heating zone is managed by a 30-segment programmable PID controller, which utilizes S-type thermocouples for extreme accuracy. The controllers provide sophisticated ramp, soak, and cool sequences, ensuring that complex thermal recipes can be executed with minimal operator intervention and maximum repeatability.

• Energy-Efficient Thermal Insulation: By employing high-purity alumina fibrous insulation, the system drastically reduces heat loss to the environment. This not only lowers operational energy costs but also contributes to more stable temperature regulation by minimizing thermal fluctuations caused by external ambient changes.

• Integrated Safety and Cooling Systems: A double-casing design incorporates three powerful cooling fans to facilitate efficient air circulation between the internal furnace and the outer shell. This safety-first approach ensures that the outer surfaces remain cool to the touch and protects the internal electronics from heat-induced wear.

• Flexible Gas Management Options: The inclusion of rotatable gas connectors and elbow push-in fittings allows for seamless integration into existing gas delivery manifolds. This allows researchers to introduce reactive or inert gases precisely where they are needed, supporting a wide range of chemical vapor deposition (CVD) and atmosphere-controlled metallurgical processes.
