Bottom Loaded Inert Gas Atmosphere Box Furnace 1400C Maximum Temperature 125L High Capacity Laboratory Heat Treatment System

Product Overview

This high-capacity thermal processing system represents the pinnacle of industrial heating technology, specifically engineered for the demanding requirements of material science and industrial R&D. By integrating a sophisticated bottom-loading mechanism with an airtight vacuum-sealed chamber, the equipment allows for the seamless processing of large or heavy samples under strictly controlled atmospheres. This system provides an ideal solution for researchers and manufacturers requiring a blend of high-volume capacity, thermal uniformity, and high-temperature capability, ensuring that complex heat treatment cycles are executed with repeatable precision.

Designed for versatility, the equipment excels in environments where the prevention of oxidation or decarburization is critical. The large 125-liter heating chamber is capable of maintaining temperatures up to 1400ºC, making it suitable for a wide range of applications from ceramic sintering to advanced metallurgical processes. The combination of high-purity alumina fiber insulation and high-performance heating elements ensures rapid heating rates and superior energy efficiency, providing a robust platform for both academic research and industrial-scale development.

Reliability is the cornerstone of this design. Built with a heavy-duty stainless steel frame and a specialized water-cooling jacket, the unit is constructed to withstand the rigors of continuous operation in high-stakes laboratory and production environments. The integration of advanced safety features, including over-temperature alarms and secondary thermocouples, provides operators with the confidence to conduct long-dwell thermal cycles unattended, ensuring that critical experiments and production batches are protected against unforeseen deviations.

Key Features

• Heavy-Duty Hydraulic Bottom Loading: The equipment utilizes an electrically driven hydraulic lift mechanism capable of supporting and positioning samples weighing up to 500 kg. This design facilitates the safe and ergonomic handling of massive crucibles and dense ceramic components, minimizing the risk of thermal shock or mechanical damage during loading and unloading operations.

• Precision Atmosphere Control: Engineered for complex chemical environments, this unit features a vacuum-sealed steel chamber with an integrated gas flow control system. A built-in heavy-duty vacuum pump and front-panel flow meter allow operators to purge the chamber and introduce inert gasses or oxygen with high accuracy, ensuring total control over the processing environment.

• Advanced Thermal Insulation: The interior is lined with energy-saving 1800-grade fibrous alumina insulation, coated with high-purity Al2O3. This multi-layered approach provides exceptional heat retention and limits external thermal radiation, maintaining the structural integrity of the furnace while reducing operational energy costs.

• Sophisticated Temperature Management: Equipped with a world-class Eurotherm controller, the system employs PID automatic control via a Silicon Controlled Rectifier (SCR). With 30 programmable segments, users can define complex heating rates, dwell times, and cooling curves with an accuracy of ±0.5ºC, ensuring consistent results for sensitive material synthesis.

• Robust Water-Cooling Infrastructure: To protect the vacuum seals and prolong the service life of the front door and jacket components, the system includes a comprehensive water-cooling circuit. This prevents seal degradation under high-temperature loads and maintains the safety of the outer casing for laboratory staff.

• Enhanced Process Safety: Dual S-type thermocouples are utilized to provide redundant monitoring; one serves the primary temperature controller while the second acts as an independent secondary alarm. This dual-monitoring system, combined with thermocouple failure detection, ensures the system enters a safe state immediately upon any operational anomaly.

• High-Performance SiC Heating Elements: The unit features 12 precision-placed Silicon Carbide (SiC) heating elements. These elements are chosen for their durability and ability to maintain consistent thermal output at high temperatures, supporting a continuous working temperature of 1300ºC and a peak temperature of 1400ºC.

• User-Centric Digital Interface: All operational parameters, from hydraulic lift positioning to thermal ramping, are managed via a centralized touch-screen digital control panel. This interface simplifies the management of complex protocols and provides real-time data visualization for the operator.
