PSA(Pressure Swing Adsorption)Tire Nitrogen Machine, being used widely, does not need high cost equipments, land and high salary maintenance technicians, but it can produce Nitrogen with low cost, high purity and low dew point. 

 

 

It is based on using the latest PSA technology and utilizes Carbon Molecular Sieve (CMS) to separate nitrogen from the other gases contained in air. When the air is compressed, N₂ and O₂ make up of most part of the air, however, oxygen molecules are much smaller than nitrogen and their diffuse speed is different, by using this point, the gas can be separated. After this process is finished, the CMS adsorbs the oxygen molecules, so the nitrogen produced by PSA has high purity and low dew point. Generally speaking, it is very easy to obtain the nitrogen with purity 99% and dew point -60℃. Our company is able to design and manufacture according to user’s requirements. The highest purity of nitrogen can be reached 99%.

 

The compressed air in the tire consists 20.9% of oxygen with heavy moisture, and oxygen is not stable in the tire. When the tire heats, oxygen will permeates through the tire wall. The test shows that the pervasion can stop till the pressure under the condition of 7 bar and the oxygen falls by 5%. Oxygen and moisture are harmful to the tire and wheel hub.
