How does the nitrogen-making machine work on site?

Producing your own nitrogen instead of outsourcing it has three main advantages, including reducing costs, eliminating waiting times, and providing consistent purity.Currently, there are two available nitrogen production designs: membrane and pressure change adsorption (PSA) generator.As field nitrogen manufacturing machines become increasingly common fixtures in a variety of industrial applications, you might wonder how they work and what the benefits of different models are.Although these systems are not responsible for producing nitrogen, they work by extracting nitrogen already present in our surrounding air and increasing their concentration by removing other molecules like water, carbon dioxide and argon to achieve the desired purity level.

How to produce nitrogen in the field nitrogen generator

Avoid paying ongoing costs for your nitrogen supply.One of the best solutions is to produce your own nitrogen using an field nitrogen manufacturing system.We provide reliable product knowledge.Also, check the following for more information about how the nitrogen generator works：

Membrane nitrogen machine

Membrane technology is used to separate nitrogen molecules from other gas molecules (such as oxygen).Dry compressed air is filtered through a bundle of hollow porous fibers in which water and gas molecules evaporate into the air, while nitrogen flows through the distribution system. Increasing nitrogen flow brings more oxygen into the air stream, which in turn reduces the purity of nitrogen.Therefore, reducing the nitrogen flow rate will increase its purity.Through the combination of membrane bundles, different purity levels can be reached to satisfy multiple applications.

PSA nitrogen generator

Air enters through an intake valve where two chambers contain a carbon molecular sieve (CMS).The CMS contains tiny pores, ideal for filtering out unwanted molecules of oxygen and other gases.Nitrogen is able to pass through this stage without being detected because of its molecules being larger than oxygen molecules. Over time, the CMS will absorb excessive oxygen molecules and be unable to effectively separate the gas.For this reason, the PSA nitrogen maker is always designed to have at least two chambers —— one for actively separating the gas and the other purged with high purity nitrogen to eliminate oxygen accumulation.Typically, the generator will switch between the two chambers approximately once every 60 seconds.
