Personalization

Upgrade to Eurotherm Temperature controller
OTF-1200X-S-FB is a UL/CSA ready to pass and a Fluidized Bed Vertical Furnace with 1'' O.D Quartz Tube (2'' O.D enlarged central area) for powder CVD ( FBCVD)applications. It consists of a vertical positioned cylindrical heating chamber that surrounds the quartz tube with a built-in filter right in the lower middle section of the central heating zone. Its filter is a porous (15~40 microns) quartz frit that allows the controlled gas flow passes through and floats the particles on a cushion of the gas stream where the interaction between the solid and gaseous materials takes place.
 
SPECIFICATIONS:
Fluidized Zone



  • Provides uniform distribution of the gas blast over the entire cross-section of the tube chamber
  • Solid particles are suspended by an upward gas flowing
  • Excellent heat transfer and coating to every single suspended particle 
  • Processed materials can be discharged from the top side of the tube after the cap is been taken off

Note: The gas is passed upward through the fluidized bed at a high enough velocity to lift the particles. However, particles may be swept away from the tube chamber entirely if the velocity was set too high. Depends on the particle size, you may want to adjust the gas in pressure and flow rate until particles are lifted and move turbulently inside of the tube.

Quartz Frit

  • Frits with forced convection design can trap the particles within the central heating area
  • Frit: 15~40 microns porous, 22mm O.D x 4mm thick
             
Optional Tube


  • You may consider SS310 high-temperature stainless steel tube for processing high-pressure materials.
  • Max. working temperature 800ºC
  • Max. Pressure 3 bars (built-in over-pressure valve which can be automatically reset and reusable)
  • ALD delivery system may be added on the top furnace for powder coating

  • Tube furnaces with quartz tube is designed for using under low positive pressure < 0.2 bars / 3 psi / 0.02 Mpa
  • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
  • Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
