0.0/5 rating (0 votes)

Description

Part Number: OTF-1200X-S-FB

 

OTF-1200X-S-FB is an 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 applications. It consists a vertical-positioned cylindrical heating chamber which 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 pass through and float the particles on a cushion of the gas stream where the interaction between the solid and gaseous materials take 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 particles 
  • 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
        
Furnace Casing
  • Double layer steel structure with air cooling
  • Split door design for easy installation of tube
  • High purity Al2O3 fibrous insulation designed for maximum energy saving

Warning

Click here to learn the installation of a gas regulator

  • Tube furnaces with quartz tube is designed for using under low positive pressure < 0.2 bar / 3 psi / 0.02 MPa
  • The flow rate for gases should be limited to < 200 SCCM (or 200 ml/min) for reducing thermal shocks to the tube
  • Attention: A two stage pressure regulator must be installed on 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
