Whether utilized for solid-state battery research or the development of high-performance technical ceramics, this system offers the versatility to operate under various gas conditions or high-vacuum levels. The compact footprint allows it to be integrated into space-constrained laboratory environments without sacrificing the performance or safety standards expected in heavy-duty industrial applications.

Confidence in this equipment is built through rigorous engineering and the inclusion of high-specification components. The furnace is pre-configured to meet stringent safety standards and is ready for UL/CSA certification, ensuring compliance with international laboratory safety protocols. The double-layer steel casing and integrated cooling fans provide exceptional thermal management, keeping the outer surface at a safe temperature even during prolonged high-temperature cycles. This robustness, combined with a precision digital control interface, ensures consistent results and long-term operational reliability under the most demanding research conditions.

Key Features

• Superior Heating Performance: Equipped with four Swedish-made Kanthal Super-1800 MoSi2 heating elements, the system achieves rapid heating rates up to 10°C/min and maintains a continuous working temperature of 1720°C, reaching a maximum peak of 1750°C for specialized processes.
• High-Precision SCR Power Control: Utilizing a Silicon Controlled Rectifier (SCR) with phase angle firing, the unit offers significantly higher accuracy and stability compared to standard solid-state relays. This advanced power management reduces thermal shock to the heating elements, extending their lifespan and ensuring ±1°C control accuracy.
• Advanced Alumina Processing Chamber: The unit features a premier-grade alumina processing tube from the USA, characterized by high purity (>99.9%). This ensures that materials remain free from contamination while providing the structural integrity required to withstand extreme thermal gradients.
• Intelligent Temperature Programming: The integrated digital controller features 30 programmable segments, allowing for precise customization of heating rates, dwell times, and cooling curves. This level of control is critical for complex sintering profiles and repeatable experimental outcomes.
• Enhanced Thermal Efficiency and Safety: A double-layer steel casing with dual internal cooling fans keeps the exterior shell temperature below 60°C. Coupled with high-purity alumina refractory insulation, this design maximizes energy savings and protects laboratory personnel.
• Flexible Atmosphere Management: The system includes a pair of stainless steel vacuum sealing flanges with double silicone high-temperature O-rings. Integrated needle valves and a dial vacuum gauge allow for immediate transition between vacuum, inert gas, or reducing atmosphere operations.
• Industrial Grade Connectivity: A built-in RS485 communication port enables remote operation and data logging via PC. When equipped with the optional control module, users can monitor and control the thermal process from an external workstation, reducing the need for constant manual supervision.
• Robust Vacuum Integrity: The flange system is capable of reaching vacuum levels as low as 50 mTorr with a standard mechanical pump and 10^-5 Torr when paired with a turbo molecular pump, providing the clean environment necessary for high-purity material processing.
