The system for regenerating desiccant in an air dryer of claim 16 wherein the measurement means controls a high heating period with high heat sequencing where heater is switched ON to maintain a high set point to substantially burn-off captive moisture on the desiccant, a low heating period and low heat sequencing; where heater is switched ON to maintain a low set point and essentially start the cooling process, while maintaining a about 200\xb0 F. heat to prevent further re-loading of blower ambient air.
18. The system for regenerating desiccant in an air dryer of claim 15, wherein said deep cooling desiccant bed flow temperature occurs upon early termination of primary high heating period for high heat of about 400\xb0 F. and secondary low heating period for low heat of about 200\xb0 F. of heater purge flows to cool and save operating energy during the regeneration process.
19. The system for regenerating desiccant in an air dryer of claim 15, wherein said desiccant bed bottom area temperature means controls the temperature of the purge flows of both heating phase and cooling said measurement of purge flows in the dryness of the desiccant bed to determine the timing of the deep cooling process.
20. The system for regenerating desiccant in an air dryer of claim 19, wherein said measurements allow for early termination of heating and the early termination of cooling phases of operation once deep cooling has been achieved.
