Modular Tube Furnace, Universal Mounting, up to 1200˚C-FeCrAl Heaters-Split Tube

Categories: Code:
RCT-BW1-1200 furnace family was designed to provide a flexible and functional laboratory solution. This furnace family is suitable for harsh and demanding thermal processes environment up to 1200 ˚C. The furnace can operate in a vertical, horizontal or any intermediate angle position with no restriction.
The hot zone is constructed from high resistance, low porosity ceramic materials. The low density fibrous back insulation allows for rapid heat up and cool down rates while, in conjunction with the double wall design, minimizing energy consumption. The semi-exposed dense structure of metallic resistance (FeCrAl) yielding in extremely uniform thermal distribution profiles. Combined with suitable high heat resistant tube this furnace model is an excellent choice for a number of demanding processes, like combustion-incineration, metal melting under inert or hydrogen atmosphere, fluidized or fixed bed reactions, catalyst testing etc. 
  • Hinged split tube or closed tube construction.
  • Maximum Continuous Temperature 1200 ˚C.
  • FeCrAl resistors. Uniform radial thermal distribution.
  • Excellent price per performance ratio. Best seller model for the R&D laboratory.
  • Bench top model with stand allowing unlimited positioning flexibility. Available with an automated lifting mechanism.
  • Universal, vertical and horizontal operation.
  • Optionally three zone construction upon request.
  • Comes with integrated controller and remote interface unit.

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.

Stand equipped with electronically actuated Lifter allows furnace body up/down linear motion.
Motion is manually actuated through side keyboard and through PYROLOGISM software.
Automated motion programming is possible through PYROLOGISM.

Reaction tubes.
  • 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.

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 (recommendedfor thin wall Quartz tube reactors).
