High Temperature Muffle Furnace with Dual Controllers and 36L Large Chamber 1700C Max

Product Overview

This high-temperature thermal processing system represents a pinnacle in laboratory engineering, specifically designed to meet the rigorous demands of material science research and industrial heat treatment. By integrating a 36L internal chamber with a maximum operating temperature of 1700°C, this equipment provides a robust platform for sintering high-purity ceramics, performing metallurgy experiments, and conducting complex thermal cycles. The core value proposition lies in its unique dual-controller architecture, which provides an unprecedented level of safety and process redundancy for long-duration experiments where sample integrity and equipment protection are paramount.

Primarily utilized in academic R&D laboratories, aerospace material testing, and industrial quality control, this unit excels in environments that require precise atmospheric control and high-temperature stability. Whether the objective is proximate analysis of raw materials, ash determination at 500°C, or volatile matter determination at 920°C, this system offers the versatility to handle diverse thermal profiles. The inclusion of an inert gas route allows for processing under protected atmospheres, expanding its utility to include oxidation-sensitive materials and advanced chemical vapor deposition support.

Reliability is engineered into every component of this furnace. From the high-grade MoSi2 heating elements to the high-purity alumina fiber insulation, the equipment is built to withstand continuous operation at 1600°C without compromising structural integrity. The double-shell steel construction incorporates forced-air cooling, ensuring that the exterior remains safe to touch even during peak internal temperature phases. This focus on performance and safety ensures that researchers can conduct demanding experiments with complete confidence in the equipment’s longevity and operational consistency.

Key Features

• Redundant Dual-Controller System: This system features two independent sets of temperature controllers and two B-type thermocouples. The primary controller manages the user-defined heating program, while the monitoring controller acts as a fail-safe, activating a secondary alarm and cutting power if the primary unit fails, ensuring maximum protection for expensive samples.
• High-Grade MoSi2 Heating Elements: Equipped with ten Super 1800 grade Molybdenum Disilicide (MoSi2) heating elements, the furnace achieves rapid heating and maintains exceptional stability at temperatures up to 1700°C. These elements are chosen for their ability to withstand high power density and resist oxidation at extreme temperatures.
• Precision PID Programming: The advanced digital controller offers 30 programmable segments, allowing users to meticulously define heating rates, cooling rates, and dwell times. The built-in PID auto-tune function minimizes temperature overshoot and maintains a remarkable ±1°C accuracy.
• Enhanced Thermal Insulation: Utilizing high-purity alumina fiber bricks and a specialized 1765°C rated alumina coating inside the chamber, the furnace minimizes heat loss and maximizes energy efficiency. This multi-layered insulation approach significantly extends the service life of the refractory components.
• Integrated Gas Management: A dedicated gas inlet with a 1/4" O.D. tube fitting and a front-mounted 160 scm float meter allow for the precise introduction of inert gases. This enables researchers to control the internal environment and protect samples from atmospheric contamination during the heat treatment process.
• Advanced Safety Interlocks: The equipment is fitted with a safety door lock mechanism that prevents accidental opening during high-temperature operation. Combined with over-temperature protection and broken thermocouple alarms, the system is designed for secure, unattended operation.
• Double-Shell Cooling Technology: The furnace housing is constructed with a double-walled steel case, separated by a cooling fan system. This design promotes air circulation, keeping the outer surface temperature low and protecting laboratory personnel from radiant heat.
• Data Connectivity and Software Integration: Fully PC-control ready, this unit includes the necessary communication cables and software. The Labview-based system enables users to manage heat-treatment recipes, record real-time data, and plot thermal profiles for comprehensive documentation and analysis.
• Universal Power Compatibility: The universal digital power controller is designed to operate efficiently at 50-60 Hz, ensuring consistent performance in diverse global laboratory environments without the need for complex power conversions.
