N2-PSA PSA Nitrogen Gas Generators
We first began marketing The PSA Nitrogen generation system in Japan using carbon molecular sieve(CMS)in 1979.

|---|---|
| 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) |
| Features | 1.On-site nitrogen production at lower cost. 2.The most experienced gas separation technology in the world. 3.Flexibility to meet the customer's needs. N2-PSA system is capable of meeting a wide range of requirements of nitrogen quality. 4.Automatic control on operating conditions. |
| Major Application | 1.Blanketing Blanketing and transportation of explosive or inflammable substances. 2.Purging Purging of tanks, pipes, etc 3.Heat treatment Adjustment of atmospheric condition for bright hardening, bright annealing, carburizing, nitriding, tempering, etc. 4.Atmospheric control Tire vulcanization system, CA storage, prevention of oxidation of edible oil. etc. 5.Food packing Prevention of quality deterioration of food such as tea, instant coffee, coffee, cookies, etc. 6.Manufacture of semiconductors, electronic parts, etc. 7.Reflow furnace |
