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.
