Nitrogen and Oxygen generators

Nitrogen generators and Oxygen generators extract the available nitrogen/oxygen in the ambient air from the other gases by applying the Pressure Swing Adsorption (PSA) technology. The first step in the PSA process is compressed air passing through a combination of filters and an activated carbon tower with the purpose of removing dust, entrained oil and water. The purified air is then directed to one of two adsorption vessels that are packed with carbon molecular sieves (CMS). The remaining impurities such as carbon dioxide and residual moisture are adsorbed by the CMS at the entrance of the adsorbent bed. PSA process in oxygen generators is very similar than in nitrogen generators. Just carbon molecular sieves (CMS) are replaced with molecular sieves (MS).

Oxygen generators O-GEN 

The O-GEN series oxygen generators extract the available oxygen 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 bed, which allows the oxygen to pass through as a product gas, but adsorbs other gases. The sieve releases the adsorbed gases to the atmosphere when the outlet valve is disclosed and the bed pressure returns to ambient pressure. Subsequently, the bed will be purged with oxygen before fresh compressed air will enter for a new production cycle. In order to guarantee a constant product flow, O-GEN oxygen generators use modules of two molecular sieve beds, which alternatively switch between the adsorption and the regeneration phase. Under normal operating conditions and with correct maintenance the molecular sieve beds will have an almost indefinite lifetime.
