Drying and regeneration cycle of RDB dryers:
- Drying time is 6 hours minimum. The dewpoint controller will extend until complete saturation is reached.
- Depressurisation time of saturated adsorber lasts 10 minutes.
- Heating period is temperature controlled (TS1) and relates to the saturation degree of the desiccant.
- Cooling with ambient air during 75 minutes.
- Pressurisation time of regenerated adsorber lasts 10 minutes.
- Stand-by time untill adsorption time of drying adsorber is completed.
- Change-over period of parallel drying for 10 minutes.
Top to Bottom flow direction in all cycle phases offer following advantages:
- No desiccant fluidisation at compressor start-up
- The fan is not loaded with warm, humid and dusty regeneration air.
- Pushed foreward "hot zone" in cooling phase optimizes regeneration effect..
- Pre-loading by ambient moisture will not reach the outlet of the drying adsorber.
- No compressed are is needed to support the cooling process.
