Innovations in Nitrogen Gas Generator Technology: What’s New in 2024

Nitrogen gas is important in industries ranging from food and beverage packaging to pharmaceuticals. Nitrogen is non-reactive and non-oxidizing, which means it can be used to prevent the corrosion of materials like metal and the deterioration of perishable goods like medicine, foods, and beverages.

As various industries discover more uses for nitrogen, nitrogen generator technologies continue to be in high demand. Improvements to the technology only increase the need for these devices as time goes on. In 2024, nitrogen generator technology will be more sophisticated, efficient, and beneficial than ever. Nitrogen gas technology can save businesses money, improve their efficiency, and enable revolutionary process changes for businesses that rely on nitrogen.

If your business is dependent upon nitrogen gas for important manufacturing processes, the following technological advancements could change your business forever.

The Basics of Nitrogen Gas Generation

There are multiple types of nitrogen gas generators, including PSA nitrogen gas generators and membrane nitrogen gas generators.

Membrane Nitrogen Gas Generators

Membrane nitrogen generators function by pushing air through a tube with a nitrogen generator membrane inside. This separates the unwanted gas (like oxygen) from the desired gas (nitrogen). Oxygen and other gases are vented back into the air, while nitrogen is pushed through an outlet in a steady stream.

Membrane nitrogen gas generators have no moving parts and are relatively easy to maintain.

PSA Nitrogen Gas Generators

PSA nitrogen gas generators use two tanks that work in tandem. As one tank’s carbon molecular sieve absorbs non-nitrogen particles and produces a steady stream of nitrogen, the other tank cleans its carbon molecular sieve. Once the process is finished in each tank, they switch roles and the process starts over again.

PSA generators are capable of producing higher purity nitrogen than membrane nitrogen gas generators.

Advancements in Nitrogen Generation Technology

Nitrogen generators have undergone improvements in efficiency, purity, environmental impact, and other qualities in recent years. Some examples of the changes made to nitrogen gas generators include:

  • Remote monitoring to allow for off-site monitoring and continuous operation.
  • Reduced energy requirements allow for improved efficiency and sustainability.
  • Customization to meet the needs of businesses.
  • Safety improvements to keep workers healthy and safe.

Energy Efficiency and Sustainability

Nitrogen generators are naturally energy efficient, especially when compared to alternative nitrogen delivery options, such as nitrogen cylinder rental. Whereas nitrogen cylinders are dependent upon regular delivery systems that require the use of fossil fuel-dependent vehicles, nitrogen generators stay in one place throughout their service life and need only small amounts of energy to function.

In addition, nitrogen generators have a “standby mode” that allows them to use less energy when not in use. This helps businesses save money and reduce their carbon footprint.

Modern nitrogen generator systems are more efficient than ever and require less energy to operate. This means significant energy savings for businesses and a smaller environmental impact as well.

Smart Nitrogen Generation

The term IoT (Internet of Things) refers to the modern practice of connecting devices to data networks to allow for remote monitoring and control. Just as you can connect your refrigerator, washer, or dryer to the Internet, so can you also connect your business’s nitrogen generator.

Smart nitrogen generators can be turned on and off through a remote control, and they may also be supervised and monitored through this remote control. This connectivity also allows operators to view maintenance reminders to keep up with regular maintenance. Operating your nitrogen generator is easier than ever with this smart connectivity.

Customization and Scalability

Every business needs to produce nitrogen at different rates. Customizations and scalable systems allow businesses to meet their nitrogen needs, even as those needs increase over time. The level of customization and scalability for nitrogen generators is more sophisticated than ever, and modern systems have many ways of adapting to the changing needs of businesses.

It’s important to work with your nitrogen generator supplier to anticipate your nitrogen needs now and into the future, to ensure that your custom-made system will continue to serve your company well.

Safety and Compliance

Safety features and international standards in nitrogen generation change on a regular basis. As these standards roll out, so do new nitrogen generator systems and designs to remain compatible with those standards.

Safety features like built-in sensors that continuously monitor gas levels and shutdown mechanisms that stop system malfunctions before they become dangerous can stop accidents and help ensure the safe use of nitrogen generator technology.

Choosing the Right PSA Nitrogen Gas Generator for Your Specific Application

Nitrogen gas is an in-demand product used in a variety of industries, from food packaging to steel production. In many industries, nitrogen is used to prevent products from spoiling, thus allowing food and medications to be stored longer and transported long distances. This makes nitrogen very important to our global supply chain, and an important material for many companies. Nitrogen is present in the air we breathe, but capturing nitrogen for use in manufacturing industries requires special equipment.

If you’re a business that uses nitrogen in its day-to-day manufacturing, it’s important to find the right type of nitrogen generator for your business. The best generators will efficiently produce enough nitrogen for your needs, at the purity level that you require.

Unlike cylinders or liquid nitrogen, PSA nitrogen generators are cost-effective and relatively low-maintenance. There are many benefits of quality nitrogen generators. Here’s what you need to know.

What Is a PSA Nitrogen Generator?

PSA stands for pressure swing adsorption. A PSA nitrogen generator is a device that produces nitrogen through a process that starts when compressed air is filtered to move impurities like oil and moisture. Once the air has been filtered in this way, it is passed to adsorption vessels with a special sieve that can adsorb any remaining carbon dioxide, moisture, and oxygen. Once this is done, the filtered nitrogen is produced at the desired purity, while any remaining oxygen is vented back into the atmosphere.

What Is a Membrane Nitrogen Generator?

A membrane nitrogen generator works by pushing compressed air through polymer fibers. As the compressed air moves through the fibers, the nitrogen molecules are separated from the other molecules in the air. Through this process, nitrogen is produced at the desired purity. While any remaining oxygen is vented back into the atmosphere.

PSA vs. Membrane

PSA and Membrane nitrogen generators are both similar but very different devices, so it’s important to understand those differences when trying to determine which type of generator is right for your business.

PSA Generator Purity Levels

Nitrogen purity is an important factor when trying to choose between two different types of generators. PSA nitrogen generators can provide nitrogen at a higher purity than membrane nitrogen generators. In fact, PSA generators from On Site Gas can produce nitrogen at a purity level of up to 99.9995%, depending on your needs. Knowing the purity level that’s required for your manufacturing process is important when trying to decide which type of generator is right for you, so have this information before you start shopping for a generator manufacturer.

PSA Generator Consistency

PSA nitrogen generators can reliably produce the nitrogen gas at the high purity level required. In industries where a consistent high purity level is required, PSA generators are the best product.

PSA Generator Durability and Maintenance

PSA nitrogen generators have few moving parts, so they’re long-lasting and require little maintenance. Many of On Site Gas’s PSA nitrogen generators last for twenty years or more before needing replacement. The sieve material that is used in the PSA process can last for decades with minimum maintenance.

How Does Nitrogen Help Preserve Bottles Of Wine?

Wine-making is a centuries-old process that has evolved with modern innovations to improve the quality of the wine. Wine is sensitive to bacterial contamination, which can negatively impact the wine’s color, flavor, and quality. Chemical oxidation can take a similar toll on wine.

Nitrogen gas can help preserve wine by protecting it from oxidation. Whether you’re a winemaker or simply interested in how exposure to oxygen can affect wine, here’s what you need to know about using nitrogen as a wine preserver.

How a Wine Nitrogen Injector Can Improve Wine Quality

Nitrogen gas is a colorless, odorless gas that does not impact wine’s color or flavor. While nitrogen isn’t involved in traditional wine-making, it is used in modern industrial wine distilleries. It can be used for sparging, flushing, and blanketing wine.


During the wine-making process, wine is moved through a series of vats and hoses from one fermentation stage to another. The more the wine is moved, the more oxygen it is exposed to. To prevent this exposure, the vats and hoses are flushed with nitrogen gas to eliminate oxygen and minimize the wine’s exposure.


The wine bottles are filled with nitrogen gas before and after being filled with wine. This displaces the oxygen.


Wine can absorb oxygen through the various stages of fermentation. Just as oxygen impacts wine in the hoses and vats, it can also impact wine when absorbed directly into the liquid. To prevent this from happening, the wine is sparged with nitrogen gas, which means that nitrogen is bubbled through the wine to help the wine release oxygen.

When sparging with white wine, combining carbon dioxide and nitrogen is best. When sparging red wine, it’s acceptable to sparge with nitrogen alone.

Either way, sparging with nitrogen is a cost-effective and efficient way to prevent oxidation. Nitrogen has many benefits, including its low cost and its easy availability. Using a nitrogen generator for wine is one way to sparge wine inexpensively, as nitrogen generators produce a limitless and inexpensive nitrogen source.

How to Get Nitrogen Gas for Wine Production

Wine producers can get nitrogen from portable cylinders and nitrogen generators. Portable cylinders seem a natural choice because they have no high up-front costs. However, for any business with an ongoing need for nitrogen, cylinders have a variety of disadvantages.

Namely, nitrogen cylinders represent an ongoing cost that can add up over time. In addition, cylinders can take up a lot of space in a warehouse and, at times, may take up more space than at other times. Finding space for nitrogen cylinders can be a challenge. In addition, nitrogen cylinders can experience supply chain problems. At times, finding enough cylinders to continue production can be a challenge.

The alternative to nitrogen cylinders is a nitrogen generator. Nitrogen generators are preferable for businesses with an ongoing need for nitrogen. Compared to cylinders, nitrogen generators represent a higher upfront cost, but a lower one spread out over time. Once the purchase has been made, running and maintaining a generator costs relatively low.

In addition, generators can produce limitless and reliable amounts of nitrogen. Generators often take up less space than cylinders and never encounter the same supply chain problems that cylinders experience. Nitrogen generators are even more eco-friendly than cylinders because cylinders rely on fossil fuel-burning vehicles for transportation.

Nitrogen Food Packaging: How Nitrogen Flushing Keeps Your Food Fresh

Packaged foods sold in grocery stores and convenience stores are specially packaged to keep the food fresh for a long time. Nitrogen is a crucial part of that packaging process. Whether you’re thinking about starting a business in the food industry or you’ve just always wondered how processed foods can stay safe to eat for so long, this information about nitrogen food packaging can help.

What Happens to Food Exposed to Oxygen

Oxygen causes food to deteriorate, so long-term food preservation starts with removing the oxygen from the container. Oxygen causes fats to go rancid, colors to change, and food products to spoil. There are two ways to remove oxygen from a container: Vacuum packaging the container or flushing the air out.

Vacuum Packaging Doesn’t Work For All Types of Food

Vacuum packaging is one way to remove oxygen, but this type of packaging is only safe to use for certain types of food. Beef jerky is an example of a food type that does well with vacuum packaging. During the vacuum packaging process, food is placed in a plastic sheath, and all the air is removed. Fragile foods break under these conditions, so only sturdy food items, like beef jerky and coffee beans, are appropriate food for this type of packaging.

Nitrogen Flushing Replaces Oxygen in Food Packaging

Nitrogen flushing is an excellent option for fragile foods like chips, snack foods, and crackers. During the nitrogen flushing process, nitrogen replaces oxygen inside the package. The nitrogen gas fills the package and creates a cushion, preventing the food from spoiling. Food doesn’t react with nitrogen the way it does with oxygen, so nitrogen in place of oxygen helps keep the food fresh.

The gas also prevents the sides of the bag from being crushed around the food to help keep the food intact. Nitrogen gas is harmless to people; when the bag is opened, the nitrogen escapes into the air. Since nitrogen makes up nearly 80% of the air we breathe, it’s considered safe.

How Nitrogen Packaging Food Works

Food is placed inside a package prior to flushing the package with nitrogen. A nitrogen food packaging machine forces oxygen out of the bag and then immediately replaces the oxygen with nitrogen. Once the space inside the bag has been filled with nitrogen, the bag is then sealed.

Once the bag opens, the food begins to deteriorate because it’s once again exposed to oxygen. The deterioration of the food can be slowed by clipping the bag shut and limiting the oxygen inside, but once the bag has been opened, the spoilage of the food becomes inevitable.

Are You Packaging Food? Why A Nitrogen Generator is Important

Nitrogen tanks are a common tool that food packaging facilities use to package their food. Unfortunately, nitrogen tanks are inefficient for a variety of reasons.

Problems with nitrogen tanks include:

  • Storage space. Nitrogen tanks take up a lot of room and need to be stored until they’re returned to the distributor.
  • Cost. While nitrogen tanks may seem like they don’t cost very much, they represent an ongoing cost to the business. If your business rents nitrogen tanks regularly, the costs for these tanks can add up.
  • Supply chain issues. Nitrogen tanks are susceptible to supply chain problems that can cause delays. If your supplier of nitrogen tanks is for any reason experiencing a supply problem, then your business could be at risk.
  • Environmental problems. Nitrogen delivery requires a truck to arrive at your facility on an ongoing basis, burning fossil fuels to keep your business going.

Purchasing a nitrogen generator for food packaging can solve all of these problems. A nitrogen generator is an efficient tool for producing a steady stream of nitrogen on site. Nitrogen generators are better for the environment because they’re energy efficient. They’re also cost-efficient. While a nitrogen generator does involve some upfront costs, once the generator has been purchased, the only other associated costs are the energy to keep the generator going and maintenance.

On-Site Nitrogen Generators: 5 Reasons To Make The Switch From N2 Bottles This Year

If your business relies on nitrogen for its manufacturing process, there are many reasons to switch from nitrogen tanks to an on-site nitrogen generator. Switching to an on-site nitrogen generation system can save your business money and keep your business running smoothly day in and day out. Once you know all the benefits of having a nitrogen generator for your business, you may be ready to make the switch. When this happens, On Site Gas can help. Here’s what you need to know about switching from N2 bottles to an on-site nitrogen gas generator.

1. It’s Cost-Efficient

Delivery of nitrogen can be costly. Tank rentals, delivery charges, administrative costs, and other fees can add up quickly when you’re paying for nitrogen gas delivery. What’s worse is that nitrogen is always lost during the delivery process. Your business paid for the nitrogen, but it never made it on site.

On-site nitrogen gas generation may cost more in the beginning, but this one-time cost could turn out to be far less than the ongoing cost of nitrogen tank rental. How much do you spend on nitrogen every month? How much does this amount to per year? Compare this to the price of a nitrogen generator to find out how quickly you would begin to save money if you purchased a nitrogen generator. For a free quote on the cost of a nitrogen generator, contact On Site Gas.

2. Increases Safety

Nitrogen tanks are stored at low temperatures or incredibly high pressure. Either way, this can make handling nitrogen tanks dangerous, and accidents on site can lead to injuries or worse.

OSHA standards dictate how to handle nitrogen as a compressed gas and as a liquid, however, handling nitrogen from a nitrogen generator simplifies everything. Nitrogen produced on demand from a generator is safer to handle overall and can lead to fewer on site accidents.

3. Reduces Downtime and Supply Issues

Nitrogen gas that arrives from a regular delivery of tanks or cylinders is inherently subject to delays and supply chain problems. As long as your business is relying on another business to deliver nitrogen to your site, you are at risk of a variety of problems including shortages, closings, and any other delivery-related problems.

Everything from weather to strikes can impact your delivery of nitrogen, depending on the circumstances. If your business relies on nitrogen delivery as an essential part of its operations, then you could be at risk. With an on-site nitrogen generator, your business will have an on-demand product, available at any time, as needed. This can help ensure your business operations are kept running smoothly.

4. Environmentally Friendly

It takes a great deal of energy to turn nitrogen gas into a liquid, and even more to turn the liquid back into a gas. All this energy use is bad for the environment. But what’s better for the environment is to produce nitrogen on demand from a generator.

Nitrogen generators use comparatively less energy just to run, and of course, do not use natural resources for regular delivery in the way that nitrogen tanks do. In other words, nitrogen tank delivery requires a delivery vehicle to arrive at your facility. The delivery vehicle releases pollution into the air, and also requires the use of fossil fuels to power the delivery vehicle.

Using a nitrogen generator is an excellent way to use fewer natural resources to run your business. Nitrogen generators are a greener, more eco-friendly solution.

5. Fits Specific Needs

Nitrogen generators are able to switch their purity levels for the application at hand, while tanks are not able to provide this service. Having a nitrogen generator on hand to fit the specific needs of the user is much more practical than keeping nitrogen tanks on hand for each task.
