Working Principle of Heated Regeneration Air dryers :
With taking advantage of the surface absorbability of porous solid material, the heated regeneration air dryer is a kind of equipment, which can absorb the moisture to get satisfied air with lower dew point, air dryer and better cleanliness.
It adopts active alumina, whose diameter is almost same with water molecule, as the adsorbent, it's also in line with the world advanced pressure swing adsorption (PSA) principle, that is to say, when absorbing in normal temperature, the pressure of water molecule in air is big than that in desiccant, so the former will be sucked into the desiccant, then condense to water drop, meanwhile the liberated heat will be stored at the upside of the tower. As regenerating, in order to temporary lower the desiccant absorption ability to let the water molecule effuse out, about 7% dry air will go through the regeneration tower slowly after the air being heated up to 150ºC, the stored heat also will take part in regeneration process for energy saving. For the circular employ of absorption-regeneration-absorption, the desiccant dries compressed air continuously to get deeply dried air. The technical performance already has reached the international high-level standard. It can be you ideal equipment with dew point lowering than -40ºC.
The working alternating cycle of twin tower can ensure stable output of satisfied compressed air. Its pressure dew point which can make up to -40ºC is definitely can obtain deeply dry and oil-free compressed air with high purity to meet the customer high requirements. Due to the heater, it can keep good regeneration performance with less purge air loss.
