ABSTRACT:
A dewpoint demand control apparatus comprises a probe interpoed in a dry air outlet of a regenerative dryer and responsive to the moisture content of the air at the dry air outlet for producing a corresponding moisture signal, a moisture analyzer and control responsive to the probe for producing a dry control signal when the moisture level sensed by the probe is below a preselected level and for generating a wet control signal when the moisture level at the probe reaches or exceeds the preselected level; and a power switch coupled with the power supply for the tower electrical control system and responsive to the dry control signal being present at the time of operation of the tower reversal control for reversal between the on-stream and off-stream towers for interrupting the power supplied to the tower reversal control to thereby prevent switching on-stream of the previously regenerated one of the towers, and the power responsive to the wet control signal for re-energizing the power supply for the tower electrical control system to thereby permit a previously interrupted reversal of towers and place the previously regenerated tower on-line and for returning control of the on-stream and off-stream time of the towers to the tower reversal control.
