Twin Towers Series

The OVN nitrogen generators extract the available nitrogen in the ambient air from the other gases by applying the Pressure Swing Adsorption (PSA) technology. During the PSA process compressed, cleaned ambient air is led to a molecular sieve ( CMS) bed, which allows the nitrogen to pass through as a product gas, but adsorbs other gases. The sieve ( CMS) releases the adsorbed gases to the atmosphere, when the outlet valve is closed and the bed pressure returns to ambient pressure. Subsequently the bed will be purged with nitrogen before fresh compressed air will enter for a new production cycle. In order to guarantee a constant product flow OVN nitrogen generators use two molecular sieve (CMS) beds, which alternatively switch between the adsorption and the regeneration phase.
