A tube oven is an electric oven that is specially designed for the thermal treatment of materials in a closed pipe system. It is usually heated using heating elements that heat the pipe evenly. The tube chamber can be specifically filled with different gas atmospheres, such as oxygen (oxidising), hydrogen (reducing), inert gases (inert) or in an evacuated system (vacuum), in order to create defined process conditions. Tube furnaces are often used in materials research, chemical reactions, powder metallurgy or for the production of ceramic and metallic materials. Their advantage lies in the precise control of temperature curves and reproducible process control with low gas consumption.
The institute has a large number of tube furnaces that can be used for various applications. Two HTM Reetz tube furnaces of the LOBA model, which can be operated at up to 1200 °C, are particularly noteworthy. They are characterised by their simple and robust design and can be operated in a vertical, inclined or swivelling position. The atmosphere guide is flexible and the control is separate from the furnace housing. The power range is up to 3 x 12 kW, with a maximum pipe diameter of approx. 250 mm and a heated length of up to 1500 mm. The equipment is supplemented by two tube furnaces from Ströhlein Instruments, each with a length of 1300 mm and varying tube diameters. In addition, a high-temperature furnace from Thermal Technology and another from Carbolite Gero are available, allowing a wide range of thermal process conditions to be covered.
If you would like to use one of the furnaces, please contact the person responsible for the device.
