On-site Nitrogen Generation

No matter your need or application we can provide state-of-the-art design to meet your requirement. 

We offer an extensive range of PSA nitrogen gas generators, which can be installed on-site for all industrial nitrogen applications. You can produce your own nitrogen on demand, which is a reliable and safe alternative to the need for liquid nitrogen supply or filled cylinders.

Our nitrogen gas generators are based on the well-known PSA (Pressure Swing Adsorption) technology using two pressurized columns with molecular sieves to ensure continuous production. We have first-hand knowledge of the market, development, demands and possibilities the PSA technology holds.

Your nitrogen generator will be selected specifically to match your application and budget, ensuring your nitrogen gas generation needs are met. From the smallest capacity solutions to the largest capacities.

OXYMAT can offer you 5 different solutions for your on-site nitrogen generation requirements:


As a result of extensive development efforts, the new series of OXYMAT generators has reached the lowest power consumption level in the market. For our nitrogen generators, the reduction of power consumption is more than 10%.



Our OXYMAT PSA Nitrogen Generators covers 18 standard models with capacity in the range from 0.27 to 2223.28 m3/hour. Flow measured in Nm3/h. Purity up to 99.9999%.


OXYMAT X-Series Frame built Solutions

OXYMAT X-versions PSA Nitrogen models 3 to 5 are supplied as frame built solutions, which includes: buffer vessels, filters, advanced control, dew point, pressure, temperature, flow, purity and remote monitoring.



Oxymat Purifier Action System (OPAS) is the add-on technology, making the most of any nitrogen generator. OPAS is the true add-On technology for nitrogen application requiring 1-100 ppm. OPAS can easily be integrated with already existing nitrogen generation systems resulting in high purity nitrogen at minimum costs.


OXYMAT Custom Engineered Projects

Oxymat is world leading in designing and manufacturing of turn-key, custom engineered PSA systems and nitrogen generating systems either on a single skid or inside a portable container. Special nitrogen gas generating systems for high pressure nitrogen cylinder filling. Each project is custom-built designed to meet your exact requirements to ensure that you receive the optimal system.
