High-temperature Tube Furnaces RHTH/RHTV series

Description
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 housing with slots for convection cooling

  • Models RHTV with hinges for wall mounting

  • Housing made of sheets of textured stainless steel

  • Ceramic working tube made of material C 799 incl. fibre plugs operation under air

  • Type B thermocouple

  • Switchgear separate from furnace in separate floor standing cabinet

  • Switchgear with control unit

  • Possible controller variants are the programmable B 500, C 550 and P 570 (threes) with adjustable ramps and hold times.

  • Over-temperature limit controller with manual reset for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the oven and load

  • Insulation only made of materials that are classified as not carcinogenic acc. to TRGS 905, class 1 or 2

  • Standard power supply 400 V 3/N/PE 50/60 Hz


Dimensions without tube.

Option:
  • Charge control with temperature measurement in the working tube and in the oven chamber behind the tube

  • Alternative working tubes designed for process requirements

  • Display of inner tube temperature with additional thermocouple

  • Gas-tight flanges for protective gas and vacuum operation

  • Manual or automatic gas supply system

  • Three- or five-zone control for optimization of temperature uniformity

  • Check valve at gas outlet avoids intrusion of false air
