PSA Oxygen Generator

Description

PSA oxygen generator principle
CBO series PSA oxygen generator is an automatic equipment which separate oxygen from air. According to the performance of molecular sieve, its adsorption when pressure risen and desorption when pressure loose. Molecular sieve’s surface and inner surface and interior are filled with micro pores. Nitrogen molecule has a faster diffusion rate of molecular sieve and oxygen molecules has a slower diffusion rate. Oxygen molecules are enriched in the end from the absorption tower. Oxygen generator is constructed according to the principle of operation PSA (pressure swing adsorption) and it compressed by two absorption towers filled up with molecular sieve. The two absorption towers are crossed by compressed air (previously purified oil, water,dust, etc) . While one of the absorption tower produce oxygen, the other one release nitrogen gas to atmosphere. The process comes in cycle way. The generator is controlled by PLC.
