How it works ↓
What is a PSA nitrogen generator?
It produces nitrogen on site from the site's compressed air: under pressure, a molecular sieve retains the oxygen, and two columns alternate between production and regeneration. Purity up to 99.999%, with no cylinder or bulk tank deliveries.

Flows, pressures, noise levels and dimensions recorded model by model on the catalogue sheets.
The PSA nitrogen generator produces the gas from the site's compressed air: from 2 to 160 Nm³/h, up to 99.999% purity, at 6 to 10 bar. It becomes the right choice as soon as consumption is steady, against cylinders and the tank.
Purity is chosen by the application: going from 99.5% to 99.999% multiplies the compressed air consumption by 2 to 3, and therefore the size of the compressor upstream.
PSA nitrogen generation (Pressure Swing Adsorption) separates nitrogen from compressed air with no cylinders and no deliveries. The air, dried and filtered beforehand, passes through a carbon molecular sieve (CMS) that holds back oxygen and lets nitrogen through.
The system works with two alternating towers: while one tower produces nitrogen under pressure, the other regenerates by releasing the trapped oxygen (depressurisation). The cycle switches continuously, supplying a stable flow of nitrogen.
Purity is set to suit the need: the more the flow is slowed down, the purer the nitrogen, up to 99.999%. The user produces their nitrogen on site, on demand, for the cost of the electricity.
Any site that uses nitrogen in cylinders or in a bulk tank: food processing (inerting, packaging), electronics (soldering), laser, pharma, winemaking, tyres. The PSA generator removes deliveries and dependence on a supplier, and becomes the right choice as soon as consumption is regular.
Purity up to 99.999%
Nitrogen purity is set to suit the process, up to 99.999%. You produce exactly the quality you need, without overpaying.
Total autonomy
No more cylinders or bulk tank to have delivered: nitrogen is produced on site, on demand, from the existing compressed air.
The gap widens with volume
The cost of the nitrogen produced is limited to the compressor's electricity: the gap with cylinders widens with the volume consumed and the regularity of demand.
Two alternating towers
Continuous production thanks to switching between one tower in production and one tower in regeneration: a stable, uninterrupted flow of nitrogen.

How to size an air compressor: flow, pressure and storage
Sizing a compressor properly is not a matter of picking a power rating in kW: it means calculating the real flow, the right pressure and suitable storage. A 4-step method, with a worked example.
