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
 
|
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
