1800C Bench Top Muffle Furnace with Kanthal Super 1900 Heating Elements and 3.6L Alumina Fiber Chamber

Product Overview

This high-performance bench-top thermal processing system is engineered to meet the rigorous demands of ultra-high temperature research and industrial material development. Capable of reaching a peak operating temperature of 1800°C, the equipment provides an exceptionally stable environment for sintering, melting, and alloying processes that require precise thermal gradients and rapid recovery times. By utilizing industry-leading heating technology and advanced refractory materials, this unit ensures that researchers can achieve repeatable results in a compact, laboratory-friendly footprint.

Designed for the most challenging applications in material science, the system serves as a cornerstone for laboratories specializing in advanced ceramics, metallurgy, and dental research. The core value proposition lies in its ability to maintain continuous operation at 1750°C without compromising the integrity of its internal components. This reliability is facilitated by a sophisticated double-shell cooling architecture and high-purity alumina fiber insulation, which prioritize both energy efficiency and operator safety in high-traffic research environments.

Reliability is at the heart of this furnace's design. Every component, from the premium molybdenum disilicide heating elements to the precision-tuned PID controller, is selected for its ability to perform under sustained high-heat conditions. This system is built to pass stringent international safety standards, providing procurement teams and facility managers with the confidence that their laboratory equipment meets the highest levels of engineering excellence and operational longevity.

Key Features

• Kanthal Super-1900 Heating Elements: Equipped with four genuine Kanthal molybdenum disilicide (MoSi2) elements, the equipment achieves superior ramp rates and exceptional longevity even when frequently cycled to ultra-high temperatures. These elements are specifically chosen for their oxidation resistance and ability to maintain structural integrity at the thermal limits of laboratory processing.
• Zirconia (ZrO2) Ceramic Inner Lining: The chamber is reinforced with a specialized zirconia liner capable of withstanding temperatures up to 2200°C. This high-grade refractory material provides an additional layer of thermal protection for the primary insulation, preventing degradation and ensuring the furnace maintains its performance metrics over years of service.
• Eurotherm 3000 Series Controller: This system features a world-class programmable temperature controller offering 24 distinct segments for ramping, cooling, and dwelling steps. With a temperature accuracy of ±0.1°C and built-in RS485 communication, the equipment allows for complex thermal profiles and seamless integration with laboratory data acquisition software.
• Double-Shell Air-Cooled Construction: The exterior steel case is designed with a double-layer structure integrated with high-efficiency cooling fans. This engineering choice ensures that the outer surface remains safe to the touch even during peak 1800°C operations, protecting personnel and surrounding lab equipment from radiant heat damage.
• B-Type Precision Thermocouple: For accurate feedback at extreme temperatures, the furnace utilizes a high-stability B-type (Platinum-Rhodium) thermocouple housed in an alumina protection tube. This sensor configuration provides the sensitivity required for critical material transitions and high-precision sintering protocols.
• High-Purity Alumina Fiber Insulation: The chamber is insulated with high-purity fibrous alumina, which provides excellent energy savings by minimizing thermal mass. This allows the furnace to heat up and cool down more efficiently than traditional firebrick-lined units while maintaining superior temperature uniformity throughout the hot zone.
• Integrated Safety and Compliance: All electrical components used within the unit are UL or Met recognized, ensuring the furnace is ready to meet global safety compliance requirements. The system is designed for straightforward integration into professional labs, featuring a heavy-duty power cable and a circuit architecture prepared for rigorous safety testing.
• Computer Interface and Software: A built-in RS485 port and included operation software allow users to control and monitor the thermal process from a PC. This capability is essential for logging experimental data and ensuring the consistency of long-duration heat treatments.
