Oxygen generators produce gaseous oxygen from compressed air on site and offer a cost-effective, reliable and safe alternative to traditional oxygen gas supplies such as cylinders or cryogenic liquid. Oxywise Oxygen Generators are available in 20 standard models with capacity ranging from 0,4 to 150 Nm3/hour at 95% purity. The design is made for round the clock 24/7 operation. Each generator is equipped with automatic start&stop function, enabling the generator to start and stop automatically according to the consumption.
Pressure Swing Adsorbtion (PSA) is the most commonly used non-cryogenic oxygen production process; most effective for small and medium capacities. The process operates by using two columns filled with adsorbent, a molecular sieve called Zeolite. Pre-treated compressed air enters the first column and follows up through the Zeolite. Nitrogen and some other gases are being trapped while the oxygen is allowed to flow through. When the active column is saturated, the air flow is directed to second column. The first column depressurizes allowing nitrogen to be purged out to the atmosphere and completely regenerates. The process is repeated continuously, when one column is productive, the other regenerates and at the end of each cycle they switch roles. The generator produces constant flow of purified oxygen.
|Flow rate:||0.4 Nm3/h to 150 Nm3/h|
|Purity:||90% to 95% (based on customer's requirements)|
|Operating temperature:||5°C – 45°C|
1. Air compressor with a build-in dryer and air tankHotter the air, the more capacity to hold water it has. Moisture deactivates the molecular sieve in the generator, therefore it has to be removed by refrigeration dryer and the drain system. The dryer is sized according to the maximum ambient temperature to make sure the pressure dew point is within the limit, +3°C or below.Read More
There are standardized compressed air quality classes which makes easier for manufactures to define required air quality to ensure trouble free operation of their equipment.Read More
Unfortunately neither Nm3 (normal cubic meter) or Sm3 (standard cubic meter) are complete definitions in themselves. It is essential to know the standard reference conditions of temperature and pressure to define the gas volume since there are various debates about what normal and standard should be.Read More
