Intelligent Control VPSA Oxygen Generator with Modular Design and Long Service Life for Industrial Use

VPSA oxygen producing machine

The pressure swing adsorption (VPSA for short) oxygen production device operates under normal temperature conditions. It uses molecular sieves to selectively adsorb nitrogen from the air, reduces the pressure in the adsorption tower to desorb the nitrogen adsorbed in the molecular sieves, thereby achieving an adsorption-desorption cycle operation and continuously producing oxygen with a purity of 90-95%.

Technical parameters

Technical features
1.Based on the principle of pressure swing adsorption, mature and reliable.
2.Intelligent soft cycle switching, adjustable purity and flow within a certain range. The configuration of various related system components is reasonable and the failure rate is low. Reasonable internal components, uniform airflow distribution, and reduced high-speed airflow impact.
3.Perfect process design, optimal usage effect.
4.Unique molecular sieve protection measures extend the service life of zeolite molecular sieves (carbon molecular sieves).
5.Intelligent chain unqualified oxygen (nitrogen) exhaust device, packaging product oxygen (nitrogen) quality.
6.Optional oxygen (nitrogen) device flow rate, purity automatic adjustment system, remote control system, etc. The whole machine leaves the factory without any basic equipment indoors. Pipeline pairing and installation are convenient.
7.Easy to operate, stable to run, highly automated, and capable of unmanned operation.

Working principle
According to the principle of pressure swing adsorption, high-quality carbon molecular sieves are used as adsorbents. Under a certain pressure, due to kinetic effects, there is a significant difference in the diffusion rates of oxygen and nitrogen on carbon molecular sieves. By utilizing the large amount of oxygen molecules adsorbed by carbon molecular sieves, nitrogen molecules are enriched in the gas phase, achieving oxygen nitrogen separation.

Due to the significant difference in oxygen adsorption capacity of carbon molecular sieves with different pressures, reducing the pressure can desorb the oxygen molecules adsorbed by the carbon molecular sieve, regenerate the carbon molecular sieve, and enable repeated recycling.
Adopting two adsorption tower processes, one tower adsorbs and produces nitrogen, while the other tower desorbs and regenerates, with alternating cycles to continuously produce high-quality nitrogen gas.

In addition to VPSA Oxygen Generators, we also produce PSA Oxygen Generators, storage tanks, heat exchangers and other products. If you are interested in VPSA Oxygen Systems or other products, please feel free to send an email to info@gneeheatex.com. We will be very happy to serve you.
