Use an Oxygen Generating System INTL (OGSI) oxygen generator to directly extract oxygen from the atmosphere and deliver it to industrial or medical applications used with the oxygen generator. OGSI makes on-site oxygen generators and systems, large industrial oxygen generators, and aquaculture oxygen generators, in addition to cylinder filling plants, oxygen bottles, and emergency oxygen generators. Oxygen generators are an effective, cost-saving alternative to more expensive liquid oxygen supplies or bottled oxygen. OGSI's oxygen generators that are on-site are more energy-efficient than other plants currently being sold. They work in situations that call for outputs from 175-1000 SCFH (83-472 LPM). Pressure Swing Adsorption oxygen generators in OGSI's large industrial line deliver a constant oxygen flow up to 93% (± 3%) at 45-60 psi. All of the large industrial oxygen generators are available with telemetric communication packages and are PLC-controlled.
