Areawise Associates Product Profiles Corporate Info Exhibitions Customers Approvals Wet incoming gases after passing through filter pass through the slide piston valve assembly and are directed towards chamber I where they pass upward through the desiccant.
Gas drying takes place by adsorption.
Dry gas from chamber I then passes through the Check valve assembly and then through the after-filter to the application or work area. While gas is being dried in chamber I the desiccant in chamber II where the desiccant has been wetted in the previous cycle is being simultaneously regenerated. The chamber II is depressurised to atmosphere through the purge valve in the downward direction. When the regeneration is complete, the purge valve is closed and the tower is slowly repressurised to line pressure for a smooth changeover. In regeneration process approximately 60 seconds are required for repressurisation.
