Oxygen Generator Working Principle


According to the principle of pressure swing adsorption (PSA), we utilize zeolite molecular sieve as adsorbent, because zeolite molecular sieve has the characteristics of selective adsorption, nitrogen is adsorbed by zeolite molecular sieve, oxygen is enriched in the gas phase, nitrogen and oxygen separation is achieved under the action of pressure swing adsorption (PSA). Meanwhile, we adopt the two-adsorption tower process, one tower is used for adsorption and oxygen production; the other tower is used for desorption and regeneration. The PLC intelligent program controls the pneumatic angle valve opening and closing, so that the two towers cycle alternately, continuously producing high-quality oxygen.

High oxygen purity

PSA oxygen generator plants allow us to produce high-purity oxygen from compressed air. The oxygen purity may also be ensured by cryogenic systems, but they are considerably more complex and justified only by large consumption volumes. The oxygen generators use ZMS (Zeolite Molecular Sieve) technology to produce a continuously supply of ultra-high purity oxygen and are available with internal compressors or without.


Low operating costs

By replacing the outdated air separation plants with Rocky latest air separation technology, savings from the cost of N2/O2 production are largely exceed by 50%

The net cost of oxygen produced by oxygen generators is significantly less than the cost of bottled or liquefied oxygen.


Oxygen Generators Create Less Impact on the Environment

Generating oxygen gas is a sustainable, environmentally friendly and energy efficient approach to provide pure and clean oxygen gas. Compared to the energy needed for a cryogenic air separation plant and the energy needed to transport the liquid oxygen from the plant to the facility, generated oxygen consumes less energy and creates far fewer greenhouse gases.
