Medical oxygen generator OGV series

modularVPSA

The OGV+ VSA industrial oxygen generator is 100% oil-free technology with an integrated drying layer and large turndown ratio with variable flow blower and extractor, ensuring maximum energy savings. How does an OGV+ VPSA industrial oxygen generator work? Atlas Copco OGV+ VPSA oxygen generators consists of two adsorption columns in parallel, in batch sequence switched by automatically controlled valves. Each column includes a drying layer that removes moisture plus CO2 followed by a zeolite type adsorption layer that separates the nitrogen from the air so that the desired component oxygen remains. In this VPSA process, air is sent via a blower into one adsorption column separating the oxygen present in the air from the nitrogen. Once the zeolite in this column is saturated with captured nitrogen, the adsorption cycle automatically switches to the other tower starting adsorption from a freshly regenerated bed ensuring an uninterrupted stable supply of oxygen gas. Simultaneously the first ‘saturated’ tower will be regenerated by an extractor pump that extracts the moisture and nitrogen from the adsorption material making it ready for re-use again. Benefits Lowest oxygen costs No truck shipments of liquid oxygen required. Produce oxygen at the lowest possible costs and CO2 emissions. Only produce what you need ​​Produce the amount and purity oxygen that you need, any time and on-site​. Large turndown ratio Variable flow blowers and extractor pump ensure a large turndown ratio and guarantee low energy consumption, even at reduced load. Efficient at any flow Constant low specific energy required to produce one unit of oxygen remains.
