Heat Of Compression

The hot compressed air from the compressor passes through one of the absorbers where the desiccant is regenerated by heat. The compressed air is then cooled in the aftercooler while condensation takes place in moisture separator at the same time. The compressed air then flows to th e other adsorber for drying. The desiccant adsorbs the water vapour and dried air leaves the adsorber.

The desiccant is very hot after regeneration and cannot asdsorb moisture unless it is cooled. The hot compressed air is cooled in the regn. Cooler. The cooled air is then guided through 4 way valve into the regenerated adsorber for removal of moisture.

When one adsorber has been regenerated and cooled (i.e. is ready for compressed air drying) and the other adsorber has reached the maximum adsorption capacity, the adsorbers can be switched over. The first adsorber will dry the compressed air while the other will be generated.
