PSA N2 generators

OVN series nitrogen generators extract available nitrogen from ambient air from other gases using pressure swing adsorption (PSA) technology. During the PSA process, compressed and subsequently cleaned ambient air is fed into the CMS molecular sieve, which allows nitrogen to pass through as a product gas while adsorbing other gases. The CMS releases the adsorbed gases to the atmosphere when the outlet valve is closed and the adsorber screen pressure returns to ambient pressure. Subsequently, the adsorption screen will be flushed with nitrogen before the fresh compressed air enters the new production cycle. To guarantee a constant product flow, OVN nitrogen generators use modules of two pressure vessels with CMS, which alternately switch between adsorption and regeneration phases. Under normal operating conditions and with proper maintenance, the PSA generator will have an almost unlimited life.
