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 chamber is ready for absorption
operation. The system is switched to this chamber, 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 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.
Available options
The following options are available for the dryer:
Start-up device
Signalling contacts of the control system & compressor synchronisation
Regeneration gas return
Dewpoint-sensing control
Fine filter muffler
Nozzle kit
Start-up device
A start-up device basically consists of a pressure holding device, which is located
at the rear of the dryer. The pressure holding device ensures that pressure can
build up in the dryer and adsorption take place.
It is always required when an empty compressed air reservoir or an empty
compressed air system must be filled downstream of the dryer (e.g. following
weekend shutdowns and when the pressure in the compressed air system can
frequently drop below the stated operating pressure).
