Product Overview
This specialized thermal processing system is engineered specifically for integration within high magnetic field environments, providing a stable and controlled temperature environment for advanced laboratory research. Designed to operate at temperatures up to 800°C, the equipment bridges the gap between high-temperature heat treatment and intense magnetic experimentation. Its core value proposition lies in its ability to maintain structural and operational integrity in environments exceeding 10 Tesla, where standard industrial furnaces would fail due to magnetic interference or Lorentz force stressors. By utilizing non-magnetic materials and specific heating geometry, this unit provides researchers with a reliable platform for exploring the frontiers of material science.
The primary use cases for this system involve material property characterization under varying magnetic fluxes, spanning industries from aerospace and defense to renewable energy and advanced electronics. It is an indispensable tool for investigating superconducting materials, magnetic phase transitions, and the behavior of nanoparticles. Because the furnace case is constructed from austenitic stainless steel and utilizes a sophisticated water-cooling jacket, the external surface remains safe to touch even during maximum temperature cycles, making it suitable for high-density laboratory environments where space and thermal dissipation are critical constraints.
Confidence in this equipment is derived from its robust industrial-grade construction and precision-engineered components. From the high-threshold DC power supply to the Eurotherm PID logic, every aspect of the system is designed for long-term consistency and repeatable performance. The engineering team has prioritized durability, ensuring that the unit can withstand the unique physical demands of high-field physics without compromising on thermal accuracy or safety. This system represents a premium investment for research facilities requiring the highest standards of reliability in complex multi-physics experimental setups.
Key Features
- Non-Magnetic SS316 Construction: The entire furnace case is manufactured from high-grade SS316 non-magnetic austenitic stainless steel, ensuring that the equipment does not interfere with external magnetic fields and prevents structural induction issues during high-field experiments.
- Optimized Lorentz Force Mitigation: The system employs a dual spiral-wound heating coil geometry made of Molybdenum (Mo) resistance wire. This specific winding technique is engineered to minimize the Lorentz force generated when a current passes through the element within a high magnetic field, preventing element deformation or failure.
- Precision Thermal Regulation: Equipped with a world-class Eurotherm PID programmable temperature controller, this unit offers ±0.1°C accuracy. The controller supports 50 programmable segments, allowing for complex ramping and soaking profiles tailored to sensitive material synthesis.
- Advanced Secondary Safety Monitoring: A built-in temperature monitor is integrated into the system to automatically cut off power if the surface temperature of the processing tube exceeds 70°C, protecting both the equipment and the sensitive magnetic environment it inhabits.
- High-Performance Water Cooling: The furnace case is water-cooled to maintain an external surface temperature of less than 25°C (under optimal chilling conditions). This high-efficiency thermal management is essential when the furnace is placed inside the restricted bore of a superconducting magnet.
- Programmable 15kW DC Power Supply: The equipment is powered by a high-capacity DC programmable power supply, providing 0-24VDC regulated output. This ensures clean, ripple-free power to the elements, further reducing electromagnetic noise in the experimental environment.
- Inert Atmosphere Management: The system features a pair of SS316 flanges equipped with 1/4" compression tube fittings for hermetic operation. This allows for precise gas delivery and purging, which is critical since the Molybdenum heating elements must only be operated under an inert gas atmosphere to prevent oxidation.
- Slim Profile for Magnet Integration: With an outer diameter specifically designed to fit within a minimum magnet bore size of Ø200 mm, the system enables tight integration with high-field superconducting magnets while maintaining a generous 100mm outer diameter for the processing tube.
- Enhanced Process Visualization and Control: The inclusion of dual thermocouples (S-type for the processing tube and T-type for surface monitoring) ensures comprehensive data logging and safety redundancy for high-stakes research.
- Integrated Structural Rigging: For ease of installation and maintenance, a steel rigger is permanently mounted to the top of the tube, allowing for safe lifting and precise positioning inside vertical magnet bores.
