Key Features
- Premium Swedish Kanthal A1 Heating Elements: The system utilizes imported Kanthal A1 resistance wire, capable of reaching surface temperatures of 1420℃. Unlike standard domestic alloys, these elements are uniform in resistance, preventing localized hotspots and ensuring a balanced temperature field that will not flake or produce slag over time.
- Advanced Alumina Polycrystalline Fiber Chamber: The furnace chamber is constructed using high-purity alumina fiber, formed via vacuum suction and filter molding. This Japanese-inspired technology results in a lightweight, low-thermal-mass insulation that provides exceptional energy efficiency and rapid heating/cooling response rates.
- Optimized Thermal Field Engineering: The spacing and pitch of the heating elements are precisely arranged according to thermal software simulations. By employing four-sided heating, the equipment achieves superior temperature uniformity, critical for sensitive chemical reactions and material phase changes.
- Intelligent PID Temperature Regulation: Equipped with a sophisticated 30-segment programmable controller, the system offers intelligent PID adjustment with ±1℃ precision. It includes features like power failure protection, ensuring the program resumes from the point of interruption rather than restarting from ambient temperature.
- Integrated Safety and Protection Systems: For operator and equipment safety, the unit includes an automatic open-cover power cutoff, over-temperature protection, and thermocouple failure safeguards. An integrated air switch and leakage protector provide secondary layers of electrical safety during high-current operations.
- Comprehensive Remote Monitoring and Control: The system includes a standard RS485 communication interface and dedicated software. This allows users to control parameters from a computer, observe real-time PV (Process Value) and SV (Set Value) curves, and log historical data for quality control and academic documentation.
- Durable Stainless Steel Exterior: The outer shell is finished with a high-grade, bright stainless steel surface. This choice of material prevents rust and corrosion in laboratory environments, maintaining the professional appearance and structural integrity of the unit over years of use.
- Versatile Atmosphere and Vacuum Compatibility: The equipment is designed to work with various vacuum systems and gas supply configurations. From simple mechanical pumps to high-vacuum molecular systems and mass flow controllers, the unit adapts to the specific atmospheric requirements of the user's process.
