Membrane Nitrogen Generator

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
Membrane Nitrogen Generator
  • Nitrogen output: 5～2 0 0 0 N m 3 /h
  • Nitrogen purity: 95% to 99.9%
  • Nitrogen pressure: 0.1~1.2MPa (adjustable)
  • Nitrogen dew point: -40°C or -60°C

Principle of Membrane Separation Nitrogen Generator

Membrane separation nitrogen production technology is based on the fact that nitrogen and oxygen in the air have different solubility and diffusion coefficients in the membrane under the action of pressure difference on both sides of the membrane. 

Some gases such as water vapor and oxygen with fast permeability first pass through the membrane and become rich Oxygen gas, while the nitrogen gas with slower permeability is retained and enriched, and becomes dry nitrogen-enriched gas to achieve the purpose of oxygen and nitrogen separation.

Application of Membrane Nitrogen Generator 

Membrane Nitrogen Generators are extensively utilized in various industries where a reliable and cost-effective source of high-purity nitrogen gas is required. They find critical application in the food and beverage industry for nitrogen gas packaging, preserving product freshness and extending shelf life. 

Moreover, in electronics manufacturing, these generators are used to create an inert atmosphere, preventing oxidation during soldering and component assembly. Additionally, Membrane Nitrogen Generators are employed in the oil and gas sector for blanketing and purging applications, enhancing safety and preventing combustion.

What is the service life of the molecular sieve?
The service life of the molecular sieve depends on the quality of the intake compressed air. In case the recommended standards are kept, the sieve can be operated for up to 8 years and even considerably longer.
What are the maintenance expenses for the PSA N2/O2 generators ?
In case of a use of 24 hours daily, the elements of the internal filter must be exchanged, in rotation, every six months. The valves must be exchanged every five years. The maintenance of air compressor are according to the recommendations of the air compressor manufacturer.
What are the key benefits of on-site N2/O2 generators compared to delivered gas?
  • You save up to 80% on the cost of the nitrogen or oxygen compared to buying  in bulk.
  • Payback is usually under 12 months, and the product has a typical lifetime over 10 years.
  • A constant supply is ensured: you never have to worry about a delivery not getting to you in time again.
  • Save space & minimize risk and handling errors: no need for gas bottles/liquid nitrogen tank in the yard.
  • Simplify administration to save time & money with no weekly deliveries to manage.
  • Very low running costs: uses your compressed air supply.
Are PSA N2/O2 generators safe?
Yes. As the generator does not add or take anything away from the atmospheric air, you could have one running in a closed room with no change to the overall content of the atmosphere. They also negate the need to store and move potentially dangerous high pressure cylinders on site.
