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.
