The oxygen and nitrogen generators P.S.A. are constructed in order to work in profitable way for all the duration of the service.

The costs of the gas production are only those due to the electric power consumption for the compressed air production necessary to satisfy the requirements of the generator.

The production of  gas with our systems offers numerous advantages, for example:

 - low cost of the produced gas (nitrogen between 0.2 Kw/m3 and 0.7 Kw/m3, oxygen  1.3  Kw/m3);

 - no additional expense (transport, chartering containers, losses due to the evaporation of gases);

- no risk due  to high pressure of bottles or the liquid gas containers;
