Function description
The dryer dries the compressed air supplied by the compressor and makes it available for
industrial use.
If so, installed up- and downstream fi lters purify the compressed air, feeded to resp. dissipat-
ed from the dryer.
The two vessels contain an extremely porous drying agent by means of which humidity is
removed from the compressed air and stored just as in a sponge. The stored humidity is then
removed again from the drying agent and re-introduced into the ambient environment.
To this end, the two vessels alternate between different operating modes. Whilst in one ves-
sel, compressed air is de-humidifi ed (adsorption), in the other vessel the humid drying agent
is prepared for another charge (regeneration). These two states, which run in parallel during
compressed air preparation, are described below.
Adsorption
Via a compressor, humid compressed air is
supplied to the compressed air inlet of the
dryer. From here, the compressed air fl ows
upwards through the absorption vessel, which
is pressurised. In so doing, the drying agent
dehumidifi es the air. The dry compressed air is
supplied to the pipe network via the com-
pressed air outlet of the dryer.
Regeneration (running in parallel to the adsorption)
At the same time the other chamber is prepared for a renewed take-up of humidity. This
process is called regeneration.
The regeneration is subdivided into three phases: expansion, dehumidifi cation, and pres-
sure build-up.
With the dewpoint-sensing control option, the regeneration phase is followed by a standby
phase.
