Gas production on site - oxygen, nitrogen

Numerous industries require on-site generation and production of oxygen and nitrogen.

  • Oxygen
    • Fish farming
    • Glass industry
    • Healthcare
    • Ozone
    • Veterinary
    • Water treatment
  • Nitrogen
    • Electronics
    • Food packaging
    • Laser cutting
    • Pharmaceutics
    • Plastics
    • Petrochemical
    • Storage of flammables

Ecotao Enterprises can supply equipment for any of these industries.

Oxygen generators

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.

Oxygen generators are available with capacities ranging from 0,6 to 200 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. The touch screen control with various add on features is delivered as an option.


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.
