The Rotary Tube Furnace 1400°C – TT-RTF-40-1400 is engineered for advanced material processing, featuring an integrated heating system, automatic rotation, and a tiltable furnace body. The tube rotates 360° with adjustable speed to deliver uniform temperature distribution, while the tilting mechanism (up to 15°) allows easy material loading and unloading, making it highly efficient for laboratory and industrial applications.
This model (TT-RTF-40-1400) is equipped with a Φ60×1000 alumina tube and a 300 mm heating zone. It supports continuous operation at 1100 °C and reaches a maximum temperature of 1200 °C. Powered by 220 V/3 kW (with a 110 V option available), the furnace utilizes high-performance silicon carbide (SiC) rod heaters and an S-type thermocouple for accurate temperature control and durability, ensuring reliable performance for high-temperature research and production needs.
