Abstract
A multi-tower blower purge dryer system for use with a compressed air stream provided from a compressor is disclosed. In one form the system includes two dryers that can be alternated to dry the compressed air stream. The tower used to dry the compressed air stream can be referred to as the drying tower, and the tower being regenerated can be referred to as the regenerated tower. A number of valves and passages are used to connect the towers to one another and/or to an intake passage from the compressor. A blower purge heater is provided to regenerate the dryers. After a regeneration step in which a tower may be relatively warm, the valves can be actuated to place the warm regenerated tower in fluid communication with the intake passage from the compressor, which can then provide air to the drying tower. In this manner the regenerated tower is cooled.
