How Does a Fluidized Bath Work?
Fluidized bath technology has been used across various industrial applications for over fifty years. The system comprises a tank or inner container with a chamber at the bottom and a porous plate on top. The tank is filled with aluminum oxide media, and compressed air is fed into the chamber with sufficient pressure and flow to cause air bubbles to break the surface of the sand and rise upwards through the porous plate. Heat is radiated into the sand either directly or indirectly from the heater. Air constantly flows into the bath to mix and stir the heated media for consistent and stable thermal results. The “bubbling” media provides thermal and displacement properties similar to that of a fluid (i.e., the term “fluidization”) but at much higher temperatures than a liquid can reach. These liquid-like properties are the secret to fluidized bath technology, providing fast heat-up of immersed objects.
The aluminum oxide media provided by Accurate Thermal Systems is inert and highly safe to use. The particle size of our aluminum oxide is 120 grit, and once an item is removed from the fluidized bath, the aluminum oxide media will either fall off or can be easily removed with compressed air. A fluidized bath is not a grit or media sandblaster. Aluminum oxide is non-abrasive to immersed objects. Organic material is thermally burned off through the gentle bubbling action of fluidization.
