Profiling the temperatures in the regeneration airstream for a desiccant bed yields higher thermal efficiency. In staged regeneration, distinct heating elements are thermostatically controlled to attain progressively higher temperatures toward the hotter end of the bed. Stratified heat recovery can be used to transfer heat from process air from zones on the process side to regeneration airstreams headed for thermally corresponding zones on the regeneration side of the desiccant bed. A recirculation system diverts process air from the hottest process zone or zones directly to the hottest corresponding zone or zones on the regeneration side.
