Nitrogen Generators

Industrial Nitrogen Generators and Compressor Systems

Many manufacturing and packaging operations worldwide use nitrogen gas as a vital part of their operational processes. Wineries use nitrogen as an alternative to carbon dioxide, metalworkers incorporate it in laser cutting, lightbulb manufacturers utilize it during the manufacturing process and food companies depend on it for their preservation and packaging processes. The benefits of having a nitrogen generator on-site significantly outweigh those of choosing to have someone deliver nitrogen cylinders from the outside.

At Compressed Air Technologies, we offer a comprehensive inventory of nitrogen generators for sale or rent that can meet the needs of your specific operation.

PSA Nitrogen Generators vs. Nitrogen Membrane Generators

A pressure swing adsorption (PSA) nitrogen generator uses a carbon molecular sieve (CMS) to separate nitrogen molecules from compressed air. The CMS absorbs the oxygen under high pressure to create pure nitrogen. PSA systems use two or more adsorption columns — one type actively separates the nitrogen, while the other regenerates the nitrogen by stripping away oxygen and exhausting it.

A membrane nitrogen generator system functions through selective permeability. Each hollow fiber in the membrane system allows levels of gas permeation, causing the oxygen to separate from the nitrogen. The primary advantage of these systems is that there are no moving parts in the membrane.

While membrane generators are advantageous for their simplicity and portability, PSA generators work well in harsher, more demanding environments and produce higher purity levels.

Advantages and Benefits of Nitrogen Generators

Compared to outsourcing, having an on-site generator offers several advantages for industries using nitrogen in their operational processes. Some examples include:

  • Lower operating costs: Using a distributor to deliver nitrogen to your facility is significantly more expensive than generating it on your own.
  • Safety: When distributors furnish nitrogen to a facility, they use pressurized tanks that can be potentially hazardous to employees. Neither the PSA nor the membrane generation process requires chilling or pressurizing nitrogen to a dangerous degree.
  • Convenience: Having a nitrogen generator on-site means never having to depend on a supplier to deliver the product to your door.
  • Environmentally friendly: Using a generator reduces carbon dioxide and other greenhouse gas emissions potentially harmful to the environment.


Applications of On-Site Nitrogen Generation

Nitrogen is nonreactive, making it excellent for blanketing, purging and removing contaminants from process streams. Since nitrogen is such a versatile material, you can use it in various applications. Some of the many applications of an on-site nitrogen generator include:

Pressurized Beer Kegs and Wine

Nitrogen can replace or work with carbon dioxide to pressurize kegs for certain beers, such as ales. Using nitrogen in the beer-making process also aids in creating a smoother beer with a headier flavor. Another option is to use nitrogen gas throughout the wine-making process to preserve color, flavor and aroma.

Tire Filling Systems

Nitrogen is a popular choice for inflating tires for race cars and aircraft as it can reduce issues caused by moisture and oxygen. Nitrogen is also less likely to migrate through the tire rubber than oxygen, resulting in tires remaining more stable over the long term and with consistent inflation pressure.

Fire Suppression Systems

Nitrogen aids in fire suppression by reducing the oxygen concentration and causing the fire to extinguish while remaining at a level acceptable for human exposure for short periods.

Lightbulb Industry

Manufacturers cannot fill lightbulbs with air, as it would cause the tungsten present to combust, making nitrogen an excellent alternative. Since nitrogen is nonreactive, it illuminates the lightbulb without causing the bulb to break or ignite.

Food Industry

Using nitrogen can create an unreactive atmosphere, which aids in preserving foods. Mixing nitrogen with carbon dioxide delays food oxidation and other forms of damage.

Laser Cutting and 3D Printing

Using nitrogen in laser cutting removes excess metal from the cut surface and achieves cleaner cuts. Nitrogen is also beneficial in 3D printing as it aids in keeping the printer’s build chamber inert.


Nitrogen gas cools and dries lithium batteries to prevent high-temperature oxidation. Additionally, nitrogen can remove oxygen from the solution to reduce the risk of corrosion.


Nitro coffee has a nitrogen gas infusion for a smoother, creamier texture. Using nitrogen also adds a natural sweetness to reduce the naturally bitter taste.


Nitrogen is naturally present in biogas and can aid in creating a renewable energy source.
