High-Temperature Tube Furnaces RHTH


The high-temperature tube furnaces are available in either horizontal (type RHTH) or vertical (type RHTV) designs. High-quality insulation materials made of vacuum-formed fibre plates enable energy-saving operation and a fast heating time due to low heat storage and heat conductivity. By using different gas supply systems, operations can be performed under a protective gas atmosphere, vacuum, or even with flammable gasses.

  •   Tmax 1600 °C, 1700 °C, or 1800 °C
  •   MoSi2 heating elements, mounted vertically for easy replacement
  •   Insulation with vacuum-formed ceramic fibre plates
  •   Rectangular outer casing with slots for convection cooling
  •   Casing made of sheets of textured stainless steel (non-rusting design)
  •   Ceramic working tube including fibre plugs for operation in air, included in delivery
  •   Type B thermocouplePower unit with low-voltage transformer and thyristor controller
  •   Switching and control unit separate from furnace in own wall or standing cabinet

Additional Equipment

  •   Over-temperature limit controller with adjustable cutout temperature for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the oven and load
  •   Cascade controller with temperature measurement in the working tube and in the oven chamber behind the tube
  •   Working tubes designed for process requirements
  •   Gas-tight flanges for protective gas and vacuum operation
  •   Manual or automatic gas supply system 3-zone control for optimization of temperature distribution Stand for vertical operation

22 RHTH 80-1000/16-5 with 5-zone temperature control, used as gradiant furnace



Models in this range include the RHTH 120/150, RHTV 120/150, RHTV 120/300 and RHTV 120/600.
