Adsorption
Via a compressor, humid compressed air is
supplied to the upstream fi lter. From here, the
compressed air fl ows upwards through the
absorption chamber, 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 downstream fi lter.
Here, adsorption is shown in the left
vessel.
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
pressure build-up. With the dewpoint-sensing control option, the regeneration phase is
followed by a standby phase.
Expansion phase
During the expansion phase the pressure in the
right chamber is released via the muffl er down
to ambient pressure within just a few seconds.
The outfl ow of the compressed air becomes
noticeable due to a sudden powerful fl ow noise
at the muffl er.
Dehumidifi cation phase
Prior to being released into the pipe network,
dried compressed air is bled by means of an
orifi ce plate. This separate regeneration air fl ow
is fed through the depressurised chamber. The
humidity stored in the drying agent is taken up
by the air fl ow and expelled into atmosphere via
the muffl er.
Here, regeneration is shown in the right
vessel.
