PSA Nitrogen Gas Generators

N2-PSA PSA Nitrogen Gas Generators

We first began marketing The PSA Nitrogen generation system in Japan using carbon molecular sieve(CMS)in 1979.

Contents
Principle The molecular diameter of oxygen is slightly smaller than that of nitrogen.This difference in molecular diameter enables quicker diffusion and adsorption of oxygen in micro pores of CMS than that of nitrogen. At the same time, moisture and carbon dioxide in the air are also adsorbed in the micro pores of CMS.The above figure shows the correlation between adsorption ratio and adsorption time of oxygen and nitrogen respectively. The adsorption of oxygen is much faster than that of nitrogen. Our nitrogen gas generation system can utilize the characteristics of CMS between oxygen and nitrogen described above. (Patented)
