The heatless regenerative desiccant dryer achieves the drying purpose through “pressure change”. Because the capacity of air to hold water vapor is inversely proportional to pressure, a portion of the dry air (called regeneration air) is decompressed and expanded to atmospheric pressure. regenerative air cooling system.This pressure change allows the air to expand to become drier, and then regenerate it by flowing it through the dryer without airflow.
The desiccant layer (that is, the drying tower that has absorbed enough water vapor), the regenerated air after drying will suck out the moisture in the desiccant and take it out of the dryer to achieve the purpose of dehumidification and drying. Heatless regenerative adsorption dryers generally consume about 15% of regenerative compressed air.
