1200°C Bottom Loading Vacuum Furnace with Rapid Gas Cooling and 8.6 Inch Diameter Quartz Chamber

Product Overview

This high-performance bottom-loading thermal processing system represents a pinnacle of engineering for laboratories and industrial R&D facilities specializing in material science. By utilizing a vertical orientation with a motor-driven sample stage, the equipment provides unparalleled ease of access for loading delicate or heavy samples. The core value of this unit lies in its ability to maintain high vacuum integrity or controlled atmospheric conditions while offering rapid temperature transitions, essential for advanced metallurgical and ceramic research where phase transformations must be tightly controlled.

Designed for versatility, the system is primarily utilized in aerospace, semiconductor, and advanced manufacturing sectors for processes such as vacuum brazing, annealing, and high-temperature synthesis. The equipment is engineered to handle rigorous duty cycles, providing researchers with the confidence that results will remain consistent and reproducible over thousands of hours of operation. Its robust construction combines high-purity quartz technology with precision mechanical lifting components to deliver a reliable thermal environment for the most demanding technical requirements.

Built with safety and efficiency in mind, the unit features an air-cooled double-layer steel casing that ensures the exterior remains safe to touch even during maximum temperature cycles. The integration of high-purity alumina fiber insulation and a high-torque motor for the sample elevator ensures that every cycle is smooth, precise, and thermally efficient. Whether performing basic heat treatment or complex multi-stage vacuum sintering, this system provides the precision and reliability required by modern industrial standards.

Key Features

• Motor-Driven Bottom Loading Stage: The automated elevator system allows for the seamless insertion and removal of samples, minimizing the risk of thermal shock and physical damage to delicate substrates while ensuring repeatable positioning within the thermal center.
• Rapid Gas Quenching System: Equipped with a built-in inert gas blow system and four specialized gas delivery tubes, this unit can rapidly cool samples directly after heating, enabling precise control over microstructure development and material hardness.
• Dual-Zone Temperature Monitoring: Features two independent 30-segment programmable PID controllers; one manages the heating elements while the second monitors the actual sample stage temperature, providing comprehensive data for thermal profile analysis.
• Electric Radiation Shielding: A motorized sliding door effectively blocks thermal radiation from the heating chamber once the sample stage is lowered, protecting the operator and surrounding equipment while maintaining the internal heat of the chamber.
• Advanced Vacuum Management: The system integrates a water-cooled SS304 vacuum flange with high-quality O-ring seals, a Pirani gauge for high-sensitivity pressure monitoring, and a dual-stage rotary vane pump to achieve rapid and stable vacuum levels.
• High-Purity Quartz Chamber: The replaceable 8.5-inch internal diameter quartz chamber provides a clean, non-reactive environment for high-purity processing, capable of operating under both high vacuum and controlled gas flow conditions.
• Comprehensive Thermal Safety: Engineered with a double-layer steel casing and integrated air cooling, the furnace maintains an exterior surface temperature below 60°C, enhancing lab safety and reducing the load on facility HVAC systems.
• Precision PID Control Logic: The internal controllers offer auto-tune capabilities, overheating protection, and thermocouple break detection, ensuring that thermal cycles remain within ±1°C of the setpoint for superior process consistency.
