Abstract
A regeneration cycle control for a dessicant air dryer of the kind in which regeneration is effected by passing heated air through the bed; a thermal sensor senses the bed outlet temperature and de-energizes the regeneration air heater when a given outlet temperature T1 is reached, after which regeneration air flow is continued to cool the bed to a lower temperature T2, at which point the regeneration cycle is terminated and on-stream operation resumed. In a dual-bed dryer, the beds are maintained alternately in on-stream mode and regeneration mode.
