How Does an Atlas Copco Nitrogen Generator Work?

atlas copco nitrogen generator

Basically, an Atlas Copco Nitrogen Generator works by converting one form of energy into another form. Depending on the type of generator, it can be used within an assortment of applications. Nitrogen generators include membrane generators, PSA generators, and liquid nitrogen generators. Read on to learn more about nitrogen generators and their different types and applications.

how does a nitrogen generator work

Liquid nitrogen generator

Having a liquid nitrogen generator on your premises is very convenient. Not only does it eliminate the costs associated with the transportation and storage of liquid nitrogen, but it also provides a safe and reliable supply.

Liquid nitrogen generators are used in a wide range of applications, including cryopreservation, biological sample preservation, X-Ray diffraction, NMR signalling, and clinical applications. They are also spotless. In addition, they can produce liquid nitrogen from ambient air, which can then be pumped into a storage tank.

The Atlas Copco Nitrogen Generator stands available in various sizes, engineered to work with standard wall electricity. Atlas Copco Nitrogen Generators are also very compact and require little space. Some models are even small enough to fit in a dermatologist’s office.

Liquid nitrogen generators use a pressure swing adsorption (PSA) process to produce nitrogen from ambient air. The method uses a high-quality carbon molecular sieve as an adsorbent. This adsorbent desorbs impurities from the perspective. The nitrogen produced is then liquified, which is stored in a vacuum insulated tank.

Membrane generator

Generally, membrane nitrogen generators use a proprietary membrane separation technology to extract nitrogen from compressed air. This process can be used in a wide variety of industries. These generators are designed to provide pure nitrogen at a low cost.

A membrane nitrogen generator is an efficient way to produce nitrogen on site. These systems can be installed in a variety of industries, such as fire protection, industrial, and medical. They are also very useful in harsh environments.

Membrane nitrogen generators use hollow fibre membranes to separate air into different gases. Each molecule passing through the fibres has a specific permeation rate. These permeation rates differ for different selective gases. Some generators do not require additional filters.

Membrane nitrogen generators are also much less expensive to operate than other types of nitrogen generation systems. They are also easy to maintain. Some generators have built-in filters and air treatment. They are also much quieter than PSA generators.

Membrane nitrogen generators are a good fit for industries where there are a large number of people working. They also eliminate safety concerns associated with high-pressure cylinders. They also allow for better nitrogen recovery and purity.

PSA generator

Using Pressure Swing Adsorption, nitrogen is produced in a way that is more efficient than traditional methods. PSA uses specialised adsorbent materials to trap the target gas species at high pressure.

This process produces high-purity nitrogen that is often used in food packaging and other applications. It can also be used for laboratory instrumentation. It puts minimal strain on ancillary equipment and is more cost-effective than bulk gas supply.

PSA is a very simple and efficient process. It uses adsorbent materials that have large surface areas. These materials are typically very porous materials, such as zeolite, alumina, silica gel, and synthetic resins. The molecules of nitrogen gas are significantly larger than those of oxygen. This makes the gas molecules easy to separate from oxygen.

Typically, nitrogen generators use two towers for this process. Each tower contains absorbent materials that capture the gas molecules. The pressure in both towers will equalize once the adsorption phase ends.

Depending on the application, a nitrogen generator can last for many years with proper maintenance. It can be used for a variety of industries, including pharmaceuticals, food packaging, wastewater treatment, and chemical manufacturing.


Several industries use nitrogen as an essential chemical element. These include food, medical, industrial, research, and military applications. The benefits of using a nitrogen generator include safety, efficiency, and reliability.

Nitrogen generators are compact systems that create pure nitrogen. They are installed on-site and offer a 24-hour supply of high-purity gas. They can be adjusted for purity and flow rate and are designed to work for many years.

These systems use pressure swing adsorption technology to produce nitrogen. The process starts with an air compressor, which sends pressurized ambient air through coalescing pre-filters. These filters remove moisture and other impurities from the air. After the air is compressed, it enters an absorption tower. The air is then forced through semi-permeable membrane fibres, which separate the gases. The nitrogen gas is then released when the pressure is lowered.

Nitrogen generators are also valuable for pharmaceutical and biotech applications. This is because the gas helps to neutralize oxygen, which prevents potential hazards. In addition, the gas enhances the quality of the end product.
