Food & Membrane Generated Nitrogen
Our systems are used in many ways to improve the processing of food and food by-products that might be adversely
affected by contact with oxygen or moisture. Some of the many applications of our systems are in the sparging of
juices and wines, blanketing of processing operations and head space replacement in packaging operations.
Nitrogen is an environmentally friendly substance. It is a chemically non-reactive, colorless and odorless gas that
comprises 79% of the earth’s atmosphere.
Products: Nitrogen Membranes & NitroSwing PSA Systems
Membrane generated nitrogen has been used since the early 1990’s to ensure the highest quality product reaches the market.
Whether it is fruits and vegetables, or flowers and fish, or coffee and tea, or beer and wine, GENERON’S® unique
membrane and systems designs are tailored to meet your stringent demands.
Further, we have delivered millions of pounds of fresh produce to market fresher and better tasting than if it had been
transported by conventional methods. Our knowledge of Controlled Atmosphere (CA) and Modified Atmosphere (MAP) transportation
and storage have made us a leader in providing customized, economical and space efficient solutions to the food, beverage and
flower industries.
Modified Atmosphere Packaging
Many foods including snacks, coffee, meats, and bake goods experience increased shelf life by utilizing a packaging technique
with nitrogen-rich atmosphere. This process uses gaseous nitrogen to displace the oxygen in sealed packages and, in turn prevents
the growth of bacteria, which has a negative effect on freshness.
Controlled Storage Transportation
To extend the shelf life of fruits and vegetables, nitrogen is now used during storage to displace most of the oxygen in the
containers, thereby, slowing down the respiration and deterioration of the food.
Typical applications of Generon membranes and Nitro Swing PSA for food storage and packaging as well as other perishable goods are:
- Pest Control and Fumigation
- Packaging
- Oxidation Control of Perishable Food Stuffs
- Sparging of Liquids / Wines
- Controlled Atmosphere (CA)/ Modified Atmosphere Packaging (MAP)
- Beer Dispensing
Our controlled-atmosphere transport systems are available as:
- Truck Mounted Systems
- Shipboard Systems
Typical applications of NITROSWING PSA® systems for food processing and packaging include:
- Pest Control and Fumigation
- Packaging, fluffing, head space replacement
- Controlled atmosphere storage, oxidation control of perishable foodstuffs
- Sparging of Liquids / Wines
- Blanketing of process operations to prevent combustion
- Beer Dispensing
- Purging tanks and vessels

NOTE: Data in this table was determined from a publication of the U.S. Bureau of Mines.
Data was determined by laboratory experiments conducted at atmospheric temperature and pressure.
Vapor-air inert gas samples were placed in explosion tubes and exposed to a small spark or open
flame. In the absence of reliable data, the U.S. Bureau of Mines or another recognized authority
should be consulted.
*General industrial practice seldom uses purities below 95% for these applications. Often higher purities than 95% are utilized based on customer's internal safety standards.
