Blower Reactivated

Drying
The wet compressed air entering through butterfly valve is dried by the desiccant in one of the adsorber towers and leaves as dry air through butterfly valve and filter, after which the desiccant has adsorbed water vapour during prefixed time, it has to be regenerated.

Regeneration
After the drying the regeneration period follows. Ambient air is sucked in by a blower and heated by a heater till temperature reached at prefixed values and subsequently led through the adsorber. The adsorbed water vapour is liberated from the desiccant again by the hot air prefixed intervals or set values after which the heater will be switched off.
The blower will still run upto preset intervals to lower the temperature of the desiccant to such a value that it is suitable again for the drying process. Before the automatic switchover takes place the regenerated adsorber is pressurized. The compressed air is directed to the other adsorber to maintain a continuous drying process.
