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.
Pressure build-up phase
After dehumidifi cation the pressure in the
regenerated hollow section vessel is built up to
operating pressure, so that the switchover from
regeneration to adsorption can take place at
operating pressure level.
Pressure build-up
Standby phase (only with the dewpoint-sensing control option)
When in standby phase, the fully regenerated vessel is ready for absorption operation. The
system is switched to this vessel, as soon as the measured dewpoint at the compressed air
outlet has reached the set dewpoint value for switchover.
Switchover
When the drying agent in the adsorbing chamber has taken up a suffi cient level of humidity,
then the switchover between the vessels will be effected between the vessels. Following
switchover, the above-described process is repeated, with the adsorption and regeneration
now taking place in the respective different vessel.
