2.4 Shifting towers

Flow diagram

Flow diagram

Description

The operation cycle of the dryers is repetitive and is controlled by the regulator and a PDP- sensor. While
the desiccant in the first tower dries the compressed air, the desiccant in the second tower is being
regenerated and vice versa. Regeneration of the desiccant is achieved by means of purge air from the
dryer outlet.

A small portion of the dried air flows via the control air valve to the solenoid valves which are controlled by
the regulator and to the PDP-sensor. The air leaving the solenoid valves (when energized) is used to
