High Temperature Tube Furnace, up to 1800˚C - MoSi2 Heaters

Categories: Code:
Being able to obtain heat up rates as high as 60 ˚C per minute, reach operating temperature of 1800 ˚C and maintain it at 1750 ˚C continuously, RCT-AM2-T-1700 and RCT-AM2-T-1800 tube furnace families represent truly powerful ultrahigh temperature tubular heating devices. Equipped as a standard with our advanced remote data acquisition and control system PYROMODULAR and with the addition of an appropriate reaction tube these tube furnaces can be used for many applications requiring ultra high temperature.

End Gas Sealing Flanges and Manifolds.

THERMANSYS® is providing work-tube End Gas Sealing Flanges for vacuum or pressure conditions.

These flanges are provided with Main Port either with hydraulic thread port or with Clamp Flange (CF) port for gases inlet/outlet- connection to the tubing network. Cooling fluid recirculation compartment is standard and is removable. Up to four peripheral threads are available serving as ports for instrumentation mounting (e.g thermocouples, pressure sensors).

Versions with Clamp Flange (CF) port design provide quick-open loading port and optionally a quartz sight window.

THERMANSYS® End Gas Sealing Flanges are supplied for work tubes diameters from 1΄΄το 3΄΄. Their design allows use with tubes having diameter tolerance ±10%.

Standard versions material of construction is Stainless Steel ASME 304. Optionally for corrosive applications Stainless Steel ASME 316 is available and Aluminum for a light weight solution (recommended for thin wall Quartz tube reactors).

Reaction Tubes.

Several work tube materials to choose from:

  • Dense ceramic Alumina work-tubes for the highest temperature applications.
  • Quartz work-tubes for maximum chemical inertia and for aggressive environments to work under vacuum or low pressure conditions up to 1100 ˚C continuously.
  • KANTHAL® APMTM/APMT metallic (FeCrAl based) work-tubes to serve under vacuum or pressure up to 1250 ˚C.


Mounting Stands.

Assembled and constructed using BOSCH-REXROTH® structural profile systems these stands provide the ideal solution for vertical furnace stand alone positioning plus reactor and instrumentation mounting. Using the commercially available accessories, tubing and cable routing is easy and professionally accomplished. Stands with electronically actuated furnace move-up and down provide a solution for heating zone moving along the reactor length.
