With the wide range of available accessories, our professional tube furnaces can be designed optimally to suit various processes. By upgrading with different gas supply systems, processes can be carried out in a protective gas atmosphere, in vacuum, or under flammable protective or reaction gases. In addition to the convenient standard controllers, modern PLC controls can be used also.

  • Tube furnaces (static) with Tmax 1100 °C to 1800 °C (max. 1400 °C in vacuum) for horizontal or vertical operation
  • Rotary tube furnaces for batch or continuous processes with Tmax 1100 °C or 1300 °C
  • Different working tube materials designed for various process requirements
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording process data with a USB flash drive
