Dryer operation
Once the service access key has been entered the dryer can set into different operation modes:
1. Normal operation
The dryer will operate according the predefined pressurization and regeneration cycles with a fixed timing.
2. Purge saving (optional)
The dryer exhaust valves will be closed as long as the dew point remains at an acceptable level. If the dew
point would rise above the purge saving level, the dryer will operate in normal operation until the dew
point again reaches an acceptable level.
3. Economy saving
The dryer exhaust valves will be closed when all compressors are stopped or in unload. Whenever a
compressor is being called to deliver air, the dryer will operate in normal operation again.
