What is the difference between a PSA generator and a membrane nitrogen generator?

Nitrogen gas is used in various industries, including food packaging, electronics production, and pharmaceuticals. Weishixin have two options for generating nitrogen gas on-site, they use a PSA nitrogen generator or a membrane nitrogen generator. What are the differences between these two devices and, more importantly, how do you know which one to choose when it comes to nitrogen gas?

PSA vs Membrane Nitrogen Generators

A PSA generator, or Pressure Swing Adsorption generator, is equipment that uses a technology to separate nitrogen gas from the air. The generator works by passing compressed air through a material that absorbs oxygen and other gases, keeping only nitrogen gas to collect. Unlike the PSA generator, a membrane nitrogen generator uses a membrane to permeate nitrogen gas molecules selectively, excluding other gases. As a result, nitrogen gas is of better quality.

Which Device Suits Your Nitrogen Need?

The choice between the Weishixin PSA oxygen plant generator and a membrane nitrogen generator is determined by the following factors. If you need a high level of nitrogen purity, choose a membrane nitrogen generator. However, if you find a lower purity level and simultaneously have a high flow rate necessary, buy a PSA generator.

Investment in the PSA vs Membrane Nitrogen Generators

Companies choosing a nitrogen generator device should focus on their budget possibilities and personal requirements. The membrane nitrogen generator has a lower cost of equipment and operation. In contrast, the PSA generator imposes higher costs on companies wishing to purchase it, but it also allows for a change in nitrogen purity levels from low to high.

Two Generators Discrepancies

While the PSA generator allows you to produce the nitrogen gas with purity exceeding 99.999%, the membrane nitrogen generator gives an opportunity to obtain the nitrogen of lower purity at a reasonable cost. Thus, the first generator option is suitable for the electronics sector, for instance, and the second one might be ideal for food packaging. 

Factors to Consider When Selecting the Nitrogen Generator 

While choosing a nitrogen generator type and model, a number of criteria are vital. They include the purity level of nitrogen, the required flow rate, the installation area, and the cost of the generator. After weighting the above-mentioned factors, companies can opt for the device that meets their needs better. Therefore, PSA nitrogen generator equipment and membrane nitrogen generators are both good and bad options. However, the most crucial factor is what company’s needs are. Whether the company wants to buy the PSA generator to obtain high levels of pure nitrogen, or they would rather purchase the membrane nitrogen generator to produce the nitrogen at a lower price, companies will benefit. Weishixin has a variety of nitrogen generators, and you can find a suitable one for your business.
