Anti Corrosive Rotary Tube Furnace with 2 Inch ID Double Layer Tube for 800C at 3 Bar Pressure

Product Overview

This high-performance rotary thermal processing system is engineered to solve the twofold challenge of maintaining strict atmosphere control under pressurized conditions while resisting aggressive chemical corrosion. Designed specifically for advanced material science and industrial R&D, the unit provides a unique environment where materials can be agitated and tumbled through a heated zone while exposed to high-pressure corrosive gases. The core value proposition lies in its hybrid processing tube architecture, which allows for the safe handling of volatile and acidic environments up to 800°C, a capability rarely found in standard laboratory furnaces.

Primarily utilized for the synthesis and treatment of powders, granules, and catalytic materials, this equipment serves critical roles in chemistry, metallurgy, and energy research. The target industries include specialty chemical manufacturing, advanced carbon synthesis, and waste-to-energy processing where gases like HCl and CH4 are frequently utilized or generated as byproducts. By combining rotary motion with high-pressure gas capabilities, the system ensures complete surface exposure and consistent reaction kinetics across the entire material batch.

Built for high-duty cycles in demanding laboratory and pilot-scale environments, this unit delivers exceptional reliability through its multi-zone heating architecture and robust mechanical assembly. The structural integrity is reinforced by precision-engineered sealing flanges and high-temperature alloy components, ensuring that researchers can conduct long-duration thermal cycles with confidence. This system represents a significant advancement in thermal processing safety and efficiency, providing a stable platform for developing next-generation materials in corrosive atmospheres.

Key Features

• Hybrid Double-Layer Tube Architecture: The equipment utilizes an innovative coaxial tube design, featuring an inner quartz tube for chemical inertness and an outer SS310S high-temperature stainless steel tube for structural support. This allows the system to withstand both high internal pressure and corrosive gas exposure simultaneously at elevated temperatures.
• Precision Multi-Zone Temperature Regulation: Featuring three independent heating zones, the system provides a combined 600 mm heated length. This design allows users to create custom thermal gradients or maintain a highly uniform 300 mm constant temperature zone, ensuring maximum control over reaction kinetics.
• High-Pressure Gas Capability: Engineered to operate safely at pressures up to 3 bar, the furnace enables specialized chemical vapor deposition (CVD) and gas-solid reactions that require higher-than-ambient densities to drive specific material transitions.
• Advanced Anti-Corrosive Sealing Flanges: The sealing system is constructed from PTFE (Teflon) with rotating fixtures made from anti-corrosive steel with specialized Teflon coatings. These components are specifically chosen for their resistance to HCl and other strong corrosive agents, preventing leaks and hardware degradation.
• Magnetic Fluid Sealed Swivel Coupling: To maintain vacuum and pressure integrity during continuous rotation, the unit is equipped with an anti-corrosive magnetic fluid seal. This high-end component ensures a smooth 0-10 RPM rotation without compromising the atmosphere within the processing tube.
• Electric Tilt and Rotation Control: The entire furnace body can be tilted between 0° and 30° via an integrated electric motor. This mechanical flexibility, combined with variable rotation speeds, allows for precise control over the material transit time and tumbling intensity.
• PID Programmable Logic Controller: Each of the three heating zones is managed by a digital PID controller with 30-segment programming. This ensures ±1°C accuracy and allows for complex ramps, soaks, and cooling profiles to be automated for repeatable results.
• Enhanced Safety and Compliance: The system is built according to rigorous industrial standards and is CE certified. For facilities requiring specific North American certifications, NRTL (UL61010) or CSA options are available to meet strict workplace safety regulations.
