Compressed air is led through the inlet of the
dryer (J) and across the prefilter (18). At this
stage, the air is cleaned from particles and
condensate. The condensate is removed
via the condensate drain (20). Via a 4/2-way
plug valve (3), the air is is led into the ad-
sorption vessel (1), in which the air is dried
down to the required pressure dewpoint. Via
a non-return valve (9), the air gets into an af-
terfilter (19), in which possibly released par-
ticles from the desiccant are retained. Via the
outlet (O), the clean and dry air is getting into
the compressed air network and to the point
of use. While one vessel is in the drying
phase (adsorption), the other vessel is being
dried again (regeneration). The content of the
vessel to be regenerated is expanded via an
orifice (14) with small cross section area.
A valve (5) is opened and a partial stream of
dried air is expanded via valves (10, 11) and
led accross the desiccant bed for regenera-
tion and via the regeneration valve (5) to
atmosphere. After that, the valve (5) is
closed and pressure-build-up is effected
simultaneously via valves (10, 11) and via the
orifices (15) and the 4/2-way plug valve (4). By
allowing the vessel to de-pressurize slowly
and the simultaneous repressurization of the
vessel, any mechanical stress on the desic-
cant is reduced to an absolute minimum.
