High Temperature Three Temperature Zone Tube Furnace for Advanced Material Science Sintering and Chemical Vapor Deposition Applications

Product Overview

This high-performance three-zone thermal system represents the pinnacle of precision engineering for material science and industrial research and development. By incorporating three independently controlled heating sections, the equipment allows for the creation of an exceptionally long and stable constant temperature zone or the establishment of precise thermal gradients. This unit is designed to operate reliably at temperatures up to 1700°C, making it a critical tool for high-stakes sintering, annealing, and chemical vapor deposition (CVD) processes where thermal uniformity is non-negotiable.

Targeted at universities, research institutes, and industrial laboratories, the system provides a robust and versatile environment for experiments involving reducing atmospheres, vacuum conditions, and high-purity material processing. The dual-shell structure and advanced insulation technology ensure that while the internal chamber reaches extreme temperatures, the external surface remains cool to the touch, prioritizing operator safety and laboratory efficiency. This equipment is engineered to deliver consistent, repeatable results across demanding thermal cycles, providing the confidence required for complex scientific breakthroughs.

Built for long-term operational excellence, the system utilizes high-grade silicon molybdenum heating elements and imported alumina polycrystalline fiber insulation. These components are selected for their thermal stability and resistance to shrinkage at elevated temperatures. Whether utilized for the production of carbon nanotubes, the annealing of specialty alloys, or advanced ceramic sintering, this furnace provides the reliability and precision performance required for modern industrial and academic heat treatment applications.

Key Features

• Triple-Zone Independent Temperature Control: This system features three distinct heating zones, each managed by its own high-precision PID controller. This architecture allows users to compensate for heat loss at the tube ends or create specific temperature profiles, ensuring a significantly wider isothermal zone than single-zone alternatives.
• Premium 1800-Grade Silicon Molybdenum Elements: The equipment utilizes specialized 14mm thick heating elements. By using a 14mm hot end compared to the industry standard 12mm, the surface load is reduced, significantly extending the service life and performance stability under continuous high-temperature operation.
• Advanced Phase-Shift Soft Start Trigger: The integrated trigger system includes current-limiting and soft-start functionality. It gradually increases current during startup to minimize impact on the heating elements and limits the secondary current to 170A, preventing equipment damage and circuit trips during rapid temperature ramping.
• High-Purity Polycrystalline Alumina Fiber Insulation: Constructed using vacuum suction and filter molding, the furnace chamber features low heat capacity and low thermal conductivity. This Japanese-engineered technology ensures high reflectivity and insulation, resulting in rapid heating rates and superior energy efficiency.
• Sophisticated Vacuum and Atmosphere Management: Equipped with stainless steel flanges at both ends, the system supports a variety of vacuum levels from 10 Pa to 10⁻³ Pa. The inclusion of needle valves, pressure gauges, and optional water-cooled or hinged flanges allows for precise control of internal environments.
• Programmable Control Logic: The system employs Japan Island Electricity instrumentation with up to 40 programmable segments. It supports grouped PID control for low, medium, and high-temperature ranges, ensuring ±1°C accuracy across the entire operating spectrum.
• Robust Safety and Monitoring Infrastructure: Integrated air switches and leakage protectors provide automatic disconnection during electrical faults. The unit also features over-temperature protection and the ability to connect to a PC via RS485 for real-time data logging and remote parameter management.
• Extended Component Durability: The heating elements feature a 210mm cold end, which is longer than standard designs to ensure lower temperatures at the connections, reducing thermal stress on the electrical system and improving overall unit longevity.
