This is the simplest of all desiccant based air dryers. In this dryer two desiccant towers are used. While one tower is in drying, second tower undergoes regeneration simultaneously. Part of dry air coming out from tower in-line goes for regeneration of the second tower. Tower changeover takes place at every 5 minutes by a sequence controller mounted in control panel.
