Expansion phase
During the expansion phase the pressure in the
right vessel is released via the muffler down to
ambient pressure within just a few seconds.
The
outflow of the compressed air becomes
noticeable due to
a sudden powerful flow noise at
the muffler.
Dehumidification phase
Prior to being released into the pipe network,
dried compressed air is bled by means of an
orifice plate. This separate regeneration air flow
is fed through the depressurised vessel. The
humidity stored in the drying agent is taken up by
the air flow and expelled into atmosphere via the
muffler.
Here, regeneration is shown in the
right vessel.
Pressure build-up phase
After dehumidification 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 vessel has taken up a sufficient 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.
