High-Temperature Tube Furnace - RHTH 80/300/18 with Controller P 570 (Nabertherm, Germany)

Description: The Tube Furnace is designed for advanced thermal processing and materials research at temperatures up to 1800 °C. The system is suitable for high-temperature synthesis, sintering, annealing, heat treatment, and diffusion studies of advanced ceramics, refractory materials, borides, carbides, nitrides, oxides, and other high-performance materials. The furnace is equipped with a high-purity C799 ceramic working tube and vertically mounted MoSi2 heating elements, ensuring rapid heating, excellent temperature stability, and long service life even under demanding operating conditions. The furnace incorporates a single-zone programmable P570 touchscreen controller, enabling precise control of heating rates, dwell times, and multi-step thermal cycles. The controller supports graphical temperature profile visualization, programmable process sequences, automatic data logging, and storage of multiple heating programs, ensuring high reproducibility of experimental results. The system is designed for operation under protective gas atmospheres or vacuum, making it particularly suitable for oxygen-sensitive materials and controlled-atmosphere processing. The furnace is therefore well suited for both fundamental research and advanced materials development requiring precise high-temperature processing.
