Rotary Tube Furnaces for Batch Operation up to 1100 °C

The rotary tube furnaces of the RSRB series are ideally suited for batch operation. The permanent rotation of the working tube ensures that the charge is constantly in motion. Due to the special shape of the quartz reactor with the tapered pipe ends the batch is kept in the rotary tube furnace and can be heat-treated an arbitrarily long time period time; a controlled heating to the temperature profiles is also possible.

  • Tmax 1100 °C
  • Thermocouple type K
  • Housing made of sheets of textured stainless steel
  • Tube furnace designed as table-top model with quartz glass reactor which opens on both sides, tapered ends
  • Reactor is removed for emptying out of the rotary tube furnace. Beltless drive and hinged furnace housing (opening temperature < 180 °C) provide for very easy removal through
  • Adjustable drive of approx. 2-45 rpm
  • Switchgear and control unit separate from tube furnace in own wall or standing cabinet
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
  • Additional equipment
  • Three-zone control for the optimization of temperature uniformity
  • Temperature display unit in the working tube with measurement by means of an additional thermocouple
  • Charge control by means of an additional thermocouple in the working tube
  • Different gassing ensures good flushing of the charge with process gas through inlet on one side and outlet on other side of tube
  • Gas-tight rotary feedthrough for connection of the rotating reactor to a gas supply system
  • Check valve at gas outlet avoids intrusion of false air
  • Vacuum design, up to 10-2 mbar depending on the applied pump
  • Open on both sides reactor made of quartz glass with knobs for better mixing of the charge in the tube
  • Package for improved charging and discharging of the working tube in the following design:
    • Mixing reactor made of quartz glass with integrated blade for better mixing of the batch, closed on one side, large opening on the other side
    • Tilting mechanism to the left/to the right. For charging and heat treatment, the furnace is tilted towards the right side until the stop so that the load is charged into the rotary tube furnace. For discharge, the furnace is tilted towards the other side to discharge the powder from the reactor. It is no longer necessary to remove the reactor.
    • Rotary tube furnace assembled on base with integrated switchgear and controller, incl. transport casters
