T Series Heatless Air Dryer


Theory of Operation

 

 


Wet compressed air enters the dryer at the bottom and is directed by non-lubricated switching valves into the drying tower. The wet air encounters dry desiccant and moisture is transferred from the air to the desiccant. The direction of air flow during drying is upflow; design of the towers prevents fluidization of the desiccant. At the top of the dryer, the dry process air is directed into the regenerating tower where it is depressurized to atmospheric pressure and is used to regenerate the desiccant. After removing moisture from the desiccant, the purge air exits the dryer through a muffler and is blown out to atmosphere.

 

After a preset time, the dryer shifts towers. At tower shift, the regenerating tower is gradually repressurized, the switching valves sequentially shift and the offstream tower is depressurized. Each valve is controlled by an independent solenoid valve.
