The dual tower design of the DBP, blower purge dryer, allows for continuous absorption of water from compressed air by using a desiccant. Drying is accomplished by passing wet compressed air through the desiccant bed of one of the towers where moisture is absorbed. Regeneration of the desiccant is accomplished using a blower to pass ambient air through a low watt density heater because heated air has a greater affinity to absorb moisture. When passed through the regenerating tower at near ambient pressure, the heated air flows through the wet bed, removing water vapor previously absorbed by the desiccant | The dual tower design of the DBP, blower purge dryer, allows for continuous absorption of water from compressed air by using a desiccant.
