Bottom Loaded Inert Gas Atmosphere Box Furnace 1700C 1300C 216L Large Capacity Industrial Thermal Processing System

Product Overview

This high-performance thermal processing system represents a pinnacle in laboratory and industrial furnace engineering, specifically designed for large-scale material research and specialized heat treatments. As a bottom-loading unit, it provides an ergonomic and efficient solution for handling heavy or fragile samples that require a stable environment and controlled atmosphere. By integrating a vacuum-sealed chamber with advanced inert gas flow management, this equipment enables researchers and manufacturers to execute complex firing, sintering, and annealing protocols under high-purity conditions, ensuring that sensitive materials are protected from oxidation and atmospheric contamination throughout the entire thermal cycle.

The equipment is engineered for diverse high-temperature applications across industries such as aerospace, metallurgy, semiconductor manufacturing, and advanced ceramics. With a substantial 216-liter interior volume, this system accommodates larger production batches or oversized components that standard box furnaces cannot handle. The combination of a robust electric hydraulic lift mechanism and a water-cooled vacuum flange ensures that the system maintains structural integrity and operational safety even when running at its maximum rated temperatures. This unit is the preferred choice for facilities requiring a balance of high throughput, precision control, and uncompromising reliability in demanding industrial environments.

Built with premium industrial-grade components, this system offers unparalleled confidence in long-term performance. The use of high-purity alumina fiber insulation and specialized heating elements ensures rapid thermal response and exceptional energy efficiency. Each unit undergoes rigorous testing to verify temperature uniformity and vacuum integrity, providing procurement teams and lead engineers with the assurance that their thermal processes will be repeatable and consistent. Whether used for pilot-scale production or fundamental material characterization, this system delivers the precision and durability required to achieve world-class results in thermal engineering.

Key Features

• Heavy-Duty Electric Hydraulic Lift: The bottom-loading mechanism is powered by a high-torque electric hydraulic system capable of lifting up to 200 kg. This allows for the safe and smooth loading of heavy ceramic crucibles or metal components, minimizing the risk of vibration-induced damage to delicate samples.
• Advanced Dual-Option Heating Elements: Depending on the desired operating temperature, the system can be configured with either Silicon Carbide (SiC) elements for applications up to 1400ºC or high-performance Molybdenum (Mo) heating elements for processes reaching 1700ºC. The multi-zone arrangement ensures optimized heat distribution across the 216L chamber.
• Precision Atmosphere Control: A vacuum-sealed steel chamber combined with a comprehensive gas management system allows for precise control of the internal environment. Two integrated flow meters allow for the fine-tuning of inert gas delivery, such as Argon or Nitrogen, protecting materials from oxidative degradation during high-temperature cycles.
• Robust Water-Cooling Infrastructure: To maintain the longevity of the vacuum seals and the outer furnace skin, the system features a water-cooled front door and sealing jacket. The integrated 16L/min recirculating water chiller ensures that even during extended high-temperature runs, the critical sealing interfaces remain within safe operating temperature limits.
• Eurotherm PID Control System: Utilizing a world-class Eurotherm digital controller, the furnace offers 16 programmable segments for sophisticated heating, cooling, and dwell time management. The SCR (Silicon Controlled Rectifier) power control ensures +/- 0.5ºC accuracy, providing the stability required for sensitive material synthesis.
• Superior Thermal Insulation: The chamber is lined with 1800-grade energy-saving fibrous alumina insulation. This high-density material, enhanced with a high-purity Al2O3 coating, minimizes heat loss to the exterior environment while providing a clean, low-dust internal atmosphere for high-purity material processing.
• Comprehensive Safety Suite: Safety is prioritized with a double-layer stainless steel structure, over-temperature protection, and a secondary alarm thermocouple. An automatic power-off function activates in the event of thermocouple failure or temperature deviation, allowing for safe overnight or unattended operation.
• Integrated Vacuum Pumping Station: A heavy-duty vacuum pump is included with the system, facilitating rapid oxygen removal from the heating chamber before gas backfilling. This ensures a low-oxygen environment is established quickly, reducing cycle times and improving process efficiency.
