Nitrogen adsorption generator is a machine that allows to obtain nitrogen from air by short-cycle adsorption. It is used in industries where high purity – up to 99.999 % – gas is required.

The ONH Systems Company manufactures equipment taking into account Russian and European standards and utilises the latest technological developments. Our staff includes professionals with more than 10 years of experience in SCA-based plants manufacturing (short-cycle adsorption technology).

You get a complete turnkey and customised engineering solution. The design allows you to develop and install nitrogen facilities of various capacities to meet the needs of your enterprise. We provide equipment warranty – up to 24 months.

Technical specifications

Main technical parameters of the equipment manufactured:

  1. Purity: from 95.0 to 99.999 % vol. N2.
  2. Performance: from 1 to 835 m3/hour.
  3. Pressure: up to 15 bar.
  4. Compressed gas dew point: < -40 °C.

Our nitrogen generators are energy efficient and have a long service life.

Operating principle

Nitrotec/Nitrostrong adsorption generators consist of two separation columns (adsorbers) filled with carbon molecular sieve. Compressed air enters the column and is separated into components under pressure. Nitrogen is delivered to the consumer. The remaining gases are gradually retained by the adsorbent in the column.

Nitrogen adsorption generators

For nitrogen production by short-cycle adsorption (SCA), a molecular sieve is used, which is specially structured and has a large number of pores of the required size.

The equipment operates as follows:

  1. Molecular sieve is used as an adsorbent. It has an unlimited service life if the incoming compressed air is filtered properly.
  2. Oxygen molecules are trapped in the pores of the granules, releasing nitrogen molecules.
  3. Two columns operate in parallel (one in operation and one in regeneration mode). This ensures virtually uninterrupted nitrogen production.
  4. Nitrogen separation from the air results from the oxygen adsorption of molecular granules.

ONH Systems equipment advantages

You get a technological solution for nitrogen production from inorganic, versatile and free raw material – air. Your benefits:

Reduced operating costs Producing the exact amount of nitrogen required on site will save you costs associated with external supplies. Most of our customers recover their investment within 2 years.
Enhanced safety No need to work with heavy cylinders, no high pressure.
No logistical limitations Save time by avoiding repetitive logistics procedures – orders, delivery notes, invoices, logistics management.
Uninterrupted nitrogen supply The generator will provide an unlimited nitrogen supply on site.
Care for the environment Harmful effects are reduced by avoiding nitrogen transportation by road.

Nitrostrong and Nitrotec nitrogen adsorption generators

If you contact ONH Systems Company, you can purchase Nitrostrong and Nitrotec adsorption nitrogen generator (price is available upon your request). The units operate using short-cycle adsorption (SCA) technology. It is used for air gases static separation by means of a special molecular sieve which adsorbs oxygen under pressure.
