Working principle: Under a certain pressure, the diffusion rates of oxygen and nitrogen in the air going through the carbon molecular sieve are greatly different. In a short time, oxygen molecules are adsorbed by the carbon molecular sieve in large quantities, and nitrogen molecules are enriched in the gas phase to achieve oxygen and nitrogen separation.
Since the adsorption capacity of the carbon molecular sieve to oxygen varies significantly with the pressure, the oxygen molecules adsorbed by the carbon molecular sieve can be released from the sieve when the pressure is reduced, so that the carbon molecular sieve can be regenerated and reused.
Two adsorption tower processes are used, one tower for nitrogen production, the other tower for desorption and regeneration, and the cycle is alternated to continuously produce high-quality nitrogen.

The system can achieve the functions and coordination of any device, while the PLC device only implements the functions that this unit has. In general, FCS is more safe, reliable, convenient and intelligent.)

Psa Oxygen Adsorption Equipment
Working principle: After removing impurities such as oil, water and dust in the air purification system, compressed air enters the adsorption tower containing zeolite molecular sieve. Nitrogen, carbon dioxide, and water vapor in the air are adsorbed by molecular sieve in large quantities, while oxygen passes through the adsorbent due to the large diffusion rate, and oxygen and nitrogen separation is completed.
When the nitrogen and other impurities in the adsorption tower reach saturation, the pressure is reduced to desorption and regeneration of the zeolite molecular sieve occurs, which can then be reused.
Using two adsorption towers under the control of a PLC and set to recycling, ensures continuous production of high-quality oxygen.

(Film is oxygen enriched membrane oxygen generator, thin film with the function of enriching oxygen. Oxygen rich membranes based on membrane separation technology can be used for long-term oxygen therapy and healthcare. Membrane oxygen production equipment is a new separation method that has gradually been developed since the 1970’s. It uses differences in selective permeability of organic polymer dense films to nitrogen and oxygen. When there is a difference or pressure ratio on both sides of the membrane, oxygen rich air can be obtained on the low-pressure side (permeable side) of the membrane, while oxygen poor (or nitrogen rich) air can be obtained on the high-pressure side (retention side) of the membrane. During the entire process of separation and concentration, there is no phase change in the membrane method for oxygen enrichment, which does not require high or low temperatures and can be separated at room temperature, resulting in low energy consumption and low cost. It is an economic separation method; in addition, bacteria and dust in the air during the membrane oxygen enrichment process are blocked by the membrane and cannot pass through it. Therefore, the oxygen rich air produced is very pure, sterile, and non-toxic. The production process does not cause any pollution to the environment.)
Wide range of application, able to resist many chemical pollutants.
