1400C Bottom Loaded Inert Gas Atmosphere Box Furnace with 125L Capacity and Precision Hydraulic Lift

Product Overview

This high-temperature bottom-loading furnace represents the pinnacle of thermal engineering for material science and industrial research and development. Designed to provide a controlled environment for complex heat treatments, the system offers a substantial 125-liter capacity within a precision-machined 20" x 20" x 20" heating chamber. By utilizing a bottom-loading configuration, the equipment ensures superior temperature uniformity and provides a stable platform for heavy or delicate samples. The integration of high-purity alumina fiber insulation and silicon carbide (SiC) heating elements allows for continuous operation at temperatures up to 1300°C, with a maximum peak capacity of 1400°C, making it an ideal choice for processes requiring both volume and high-thermal intensity.

The primary use cases for this unit span across advanced ceramics, metallurgy, and semiconductor manufacturing. Its ability to maintain a strictly controlled inert gas or oxygen atmosphere makes it indispensable for applications such as sintering, annealing, and the synthesis of high-purity compounds where atmospheric contamination must be eliminated. The vacuum-sealed steel chamber, protected by an integrated water-cooling jacket, allows operators to conduct processes under vacuum or specific gas flows without compromising the structural integrity of the furnace or the safety of the laboratory environment. This makes the system particularly effective for industrial facilities focusing on aerospace components, electronic ceramics, and renewable energy materials.

Buyers can have full confidence in the reliability and performance of this equipment under the most demanding industrial conditions. Built with a heavy-duty, double-layer stainless steel structure, the unit is engineered for long-term operational consistency. The hydraulic lift mechanism is designed to handle loads up to 200 kg with precision, ensuring that even large-scale batches are handled with care. Every aspect of the furnace, from the Eurotherm PID controller to the high-grade refractory ceramics, is selected to provide a robust solution that minimizes downtime and maximizes throughput for high-stakes research and production cycles.

Key Features

• Precision Hydraulic Bottom-Loading Mechanism: The furnace utilizes an electric-driven hydraulic cylinder to raise and lower the chamber floor, supporting a maximum sample load of 200 kg. This design facilitates easier loading of heavy crucibles and significantly improves temperature uniformity across the 125-liter volume.
• Advanced Inert Atmosphere Control: Equipped with a vacuum-sealed steel chamber and a precision gas flow control system, the equipment supports processing under inert gases like Argon or Nitrogen, as well as Oxygen, preventing oxidation and ensuring material purity.
• High-Performance Silicon Carbide Heating: Featuring 12 strategically positioned SiC heating elements, the system delivers rapid, consistent heating up to 1400°C, ensuring stable thermal gradients for complex metallurgical and ceramic processes.
• Water-Cooled Double-Layer Structure: The furnace is encased in a double-layer stainless steel structure with an integrated water-cooling jacket at the front door and sealing surfaces, maintaining a cool exterior and extending the service life of vacuum seals.
• Eurotherm PID Temperature Regulation: A high-end Eurotherm controller provides PID automatic control via a Silicon Controlled Rectifier (SCR), offering 30 programmable segments for precise management of heating rates, cooling rates, and dwell times.
• Enhanced Energy Efficiency: The heating chamber is lined with 1800-grade fibrous alumina insulation and coated with high-purity Al2O3, which minimizes heat loss and reduces energy consumption during long-duration thermal cycles.
• Integrated Safety and Monitoring Systems: Built-in over-temperature protection and thermocouple failure alarms allow for unattended operation, while dual S-type thermocouples ensure redundant monitoring for critical process safety.
• High-Capacity Vacuum Integration: A heavy-duty vacuum pump is built directly into the side of the furnace frame, paired with a front-panel flow meter (0-12L/min) for seamless atmospheric management during the heat treatment process.
