We supply generators for onsite production of N2 Gas in Beverages & the Food Industry.

Food grade – Highest Quality!


Your daily business in the food industry is full of challenges as quality demands from customers are increasing. Free oxygen is a major culprit in food spoilage and provides good basis for bacterial growth. The use of nitrogen in food processing is perfect for flushing and regulating the air out of the packaging and injecting nitrogen into the packaging. This helps to protect the delicate foods inside increases the shelf life of the food.



In the beverages industry, nitrogen is used in packaging of carbonated or still beverages, beer, wine, juice drinks, tea, bottled water etc. Nitrogen is injected precisely into each container at a predetermined rate which pressurizes the container adding to its rigidity. In carbonated drinks Nitrogen pressure helps to keep the carbon dioxide in solution by occupying the container headspace which adds value to the product.

Why OXYMAT on-site systems?

By producing the nitrogen on-site, food producers can prolong shelf life, preserve freshness, taste and texture, delay rancidity, slowdown decay process and overall improvement of product quality.

Nitrogen supply from external sources are uncontrollable and at OXYMAT we understand your need for a safe and reliable source of nitrogen. You can choose to be self-sufficient with nitrogen and the most ideal nitrogen gas source is an on-site PSA onsite nitrogen gas generator.

More and more companies are investing in nitrogen generators. Reasons being cost-cutting and obtaining independency from nitrogen supplies. The systems are compact with small foot-prints and low noise levels, which makes it possible to install the units in most factories.


The PSA process is an extremely clean operation and the only ‘raw material’ is ‘air’. On-site generators allow for an uninterrupted supply of gas with a high purity output. This means that you can produce gas where and when you need it, and in the exact quantity and quality you need.

1. Compressor
increases air to required level of pressure

2. Dryer
removes moisture from air (air humidity) by cooling

3. Coal tower
adsorbs harmful organic impurities such as oil vapours and hydrocarbon compounds

4. Air tank
accumulates necessary volume of air for PSA generator

5. CMS
filling with its ion- exchange bed traps oxygen molecules  and allows nitrogen molecules to stream through

6. High Purity Oxygen
flows from PSA generator to product tank and is ready for use
