Nitrogen Generator
Nitrogen Generators
The technology for displacing oxygen with nitrogen is our core business. We specialize in designing, building, and maintaining innovative solutions centered around the nitrogen generator.
A nitrogen generator is the ideal solution for on-site production of nitrogen. It also provides a solution for industries that suffer from the undesirable effects of the oxygen molecule. Examples include a wide range of professional applications where nitrogen can be used, such as: corrosion in piping in greenhouses, fires in cold storage and freezer facilities and data centers, or the deterioration of planting and consumer goods caused by microorganisms.

How does our nitrogen generator work?
A nitrogen generator produces nitrogen by filtering oxygen out of compressed air. Our nitrogen generator uses Pressure Swing Adsorption (PSA) technology. In this technique, nitrogen and oxygen are separated by binding the oxygen molecules to a molecular carbon sieve: the Carbon Molecular Sieve (CMS).
Our patented technology
Building on existing PSA (Pressure Swing Adsorption) technology, we developed a completely new system: High Performance – PSA. This eliminates the drawbacks of a traditional PSA system. The HP technology stands out thanks to an optimized airflow within the system, as well as a unique compression system for the activated carbon. These improvements make the system environmentally friendly, significantly extend its service life, and reduce energy consumption. Our patented compression tubes require less than 2 m³ of compressed air to produce 1 m³ of 95% pure nitrogen. In addition to the generator itself consuming less energy, it can also operate with either a high-capacity or lower-capacity compressor to achieve the desired volume of compressed air.
The main advantage of the HP-PSA technology is, above all, its energy savings. Compared to a membrane nitrogen generator, energy savings of 40 to 50% can be achieved!
How does the HP-PSA technique work?
Our HP-PSA nitrogen generator uses two columns filled with carbon, which acts as a molecular sieve. Clean, dry compressed air serves as the feed for the generator and flows alternately through one of the two tubes. In this tube, the carbon absorbs oxygen and other undesirable molecules via hollow fibers, while the nitrogen flows freely through.
When saturation is reached, a smart control system depressurizes the tube. This causes the absorbed oxygen molecules to be released from the carbon. At the same time, the other tube is fed with compressed air, where the same process takes place. This cycle continues continuously. The pure nitrogen produced either goes directly to the process or is stored in a buffer tank.
By whom is nitrogen used?
Our generators produce nitrogen to displace oxygen. Various industries are affected by the undesirable effects of oxygen molecules. Examples include corrosion in piping in greenhouses, fires in cold storage facilities and data centers, and the deterioration of planting and consumer goods caused by microorganisms.
Nitrogen can be used for a variety of purposes, such as protecting heating systems in horticulture and buffer tanks. It is also used to prevent potential fires and to extend the shelf life of food.
Advantage on-site nitrogen production
Many industries are increasingly switching to generating their own nitrogen using a nitrogen generator. This offers many advantages: users always have access to the amount of nitrogen they need, with the required high purity. The desired purity can be adjusted as needed. In addition, there are no transportation costs, and there are no issues with cryogenic storage.
We develop and assemble our nitrogen generators at our own factory in Honselersdijk, and they are characterized by innovation and quality.

What is nitrogen?
Nitrogen (N₂) is an inert gas. An inert gas is a gas that does not undergo chemical reactions. It is all around us. Of all the air, 78% is nitrogen, 21% is oxygen, and the remaining 1% consists of various other gases. Nitrogen is colorless and odorless and, in its pure form, is not harmful to humans or the environment. However, it can be harmful in the form of nitrogen oxides or ammonia.
We humans do not use nitrogen, but it is very useful for many industrial processes. There are many different applications for inert gases. Inert gases are most commonly used to reduce the oxygen content in the air—sometimes even to negligible concentrations. Because nitrogen is an inert gas (and does not readily react with most materials), it protects sensitive materials and prevents oxidation, fire, and explosions.
However, the 78% found in atmospheric air isn’t pure enough for these processes. To achieve a high degree of purity, you need a nitrogen generator. A nitrogen generator produces nitrogen. The nitrogen you produce is in gaseous form. To obtain liquid nitrogen, you must first cool and compress it. We do not handle that part of the process.
