NITROPOWER Generator Operating Principle

NITROPOWER nitrogen generators operate on the PSA (Pressure Swing Adsorption) principle. The generators are based on a set of steel adsorbers filled with a special adsorbent — a carbon molecular sieve. This specially prepared material has pores of a size that preferentially absorb (adsorb) oxygen, allowing the air passing through the adsorber to be enriched with nitrogen.

The pre-dried and purified compressed air enters the generator and passes through the adsorbers in an upward direction, from bottom to top. Nitrogen molecules poorly penetrate the pores of the adsorbent, so they pass through the adsorber and enter the product line, while oxygen accumulates in the adsorbent.

Due to the limited oxygen absorption capacity of the adsorbent, NITROPOWER generators automatically switch the operating mode of the adsorbers so that one group of adsorbers absorbs oxygen while the other is being regenerated. During regeneration, the pressure in the adsorber drops and the accumulated oxygen is released to the atmosphere. The adsorbers are cyclically switched to ensure continuous nitrogen generation.

Система управления и контроля

Control System of NITROPOWER Series Generators

Equipped with an integrated gas analyser board and flow meter, the control system can be integrated into a superordinate system (factory-wide process control system) for remote monitoring and control of all processes.

Depending on the options and models selected, the following parameters can be monitored:

  • Generator inlet air temperature;
  • Generator inlet air pressure;
  • Generator discharge product gas pressure;
  • Oxygen concentration in the product gas at the generator outlet;
  • Pressure in the generator's adsorbers;
  • Product gas flow rate at the nitrogen generator outlet (optional).

Benefits of NITROPOWER Nitrogen Generator

  • Excellent Efficiency. The use of the latest technology in the design of NITROPOWER generators has made it possible to achieve the lowest air consumption per unit of product nitrogen in the world. This gives you the opportunity to save on compressor equipment and significantly reduce energy costs.
    The generators do not contain any vessels covered by PB 10-115-03. Rules for the Construction and Safe Operation of Pressure Vessels, as the volume of the adsorbers of NITROPOWER generators does not exceed 20 litres.
  • Ability to Increase Capacity. You can easily increase the capacity of your NITROPOWER generator as required thanks to its modular design, allowing you to make a phased investment.
  • Robustness and Operating Life. Often manufacturers push the maximum parameters per unit of adsorbent to save costs, resulting in rapid wear and tear. NITROPOWER generators are designed for long and robust performance. The lower linear gas velocity reduces adsorbent wear and significantly increases generator life.
  • Minimum lead time. NITROPOWER generators are usually in stock and the lead time is only determined by delivery. This means you get your equipment faster, reducing the payback period on your investment.
  • The wide product range allows you to choose the right nitrogen generator model without overpaying for excessive production capacity.
  • The high quality of NITROPOWER generators is ensured by series production, excellent build quality, the use of high quality components from leading European, US and Japanese manufacturers, and a reliable valve system. The generators are supplied fully operational.
  • Advanced Control System. A generator is equipped with a state-of-the-art control system that enables the unit's self-diagnostics and connection to the factory-wide process control system.
  • Wide Range of Services. With its extensive experience, R&P Co. Grasys is able to implement projects of any complexity, from the supply of generators to turnkey projects. R&P Co. Grasys specialists supervise the installation, commissioning, warranty and post-warranty service of the equipment supplied.
