Batch-Type Sealed Multi-Zone Rotary Furnace

The Batch-Type Sealed Multi-Zone Rotary Furnace is an advanced thermal processing system designed for uniform heat treatment of powders, granules, or small bulk materials under controlled atmospheres or vacuum. Its multi-zone heating + rotating tube design ensures excellent temperature homogeneity and mixing efficiency, making it ideal for material synthesis, calcination, reduction, and annealing in research and small-scale production.

Key Features

•  Multi-Zone Precision Heating – Independent control of 3-5 heating zones (adjustable lengths)
• Rotating Quartz/Metal Tube – 0-20 RPM programmable rotation for uniform treatment
• Gas/Vacuum Compatibility – Works with Ar, N₂, H₂, or vacuum (10⁻³ mbar) 
• High-Temperature Stability – Up to 1200°C (option for 1400°C with SiC elements) 
• Advanced Control System – Touchscreen HMI + PLC, data logging, and recipe storage 
• Safety & Automation – Over-temperature protection, gas leak detection, and auto-shutdown

Additional Equipment

• Lift door：Pneumatic door opening, controlled by foot pedal, with hot surface facing away from the operator.
• Touchscreen: Multilingual menu, multiple temperature rise process curve storage, historical curve storage, and data reports (7 inches).
• Computer Control: Controls furnace start, pause, stop, stores historical curves, sets temperature rise curves, reads temperature rise curves, sets parameters, etc.
• Siemens PLC Control: Real-time data reading with open ports for data communication with upstream and downstream equipment.
• Manual or automatic gas supply system
• Observation Window: Designed on the furnace door with high-temperature-resistant quartz glass.
• Movable Casters: Two swivel casters and two fixed casters.
• Rapid Cooling: Achieved with a frequency inverter and centrifugal fan for programmable cooling control.
• Quick Discharge Rack: The material rack is made of high-temperature steel, with wear-resistant heavy-duty refractory bricks on the top, enabling rapid
• transfer of materials from the furnace to an external platform in high-temperature environments.
• Multi-Point Temperature Control: Independent temperature control on multiple sides for improved temperature uniformity.
• High temperature furnace chamber with multi-sided heating for very good temperature uniformity.
• Stirring Fan: Metal stirring fan, can be linked with PLC to automatically start at designated temperature segments.
• Independent Control Cabinet: Separate control cabinet with an extended control cable length (up to 5 meters).
• Heat Storage Furnace Bottom: The furnace bottom sinks 50mm with a hollow design, supported by multiple vertical columns, increasing Ceramic Load-Bearing Plate and ensuring uniform heat distribution at the bottom.
• Exhaust Gas Treatment: Adds VOC exhaust gas treatment furnace with a capacity of 40m³,H or 80m³,H.
• Corrosion-Resistant Furnace Lining: Furnace lining material resistant to acids, alkalis, and hydrofluoric acid corrosion.
• Heating Element Protection: Prevents contamination from powder and corrosion from volatile substances and scratch.
• Clean Furnace Lining: Furnace lining made of ceramics, high-temperature glass, and high-temperature metals to prevent dust and volatile substances.
• Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
• Customizable charging racks according to requirements, for loading the furnace in two levels.
