VPSA Oxygen Generator Achieves 93% Purity Diffused Oxygen Supply At 3700 Meters Altitude

In plateau areas, "insufficient and unstable oxygen supply" has long restricted the development of people's livelihood and industries. However, GNEE's VPSA-2000 oxygen generator, with its solid performance of 93% purity, 0.05Mpa pressure, and 2000Nm³/h capacity, has achieved a technological breakthrough in the plateau diffused oxygen supply project at an altitude of 3700 meters, providing a "Chinese solution" for oxygen guarantee under extreme plateau conditions.

The thin air and low air pressure in high-altitude areas put strict requirements on the adsorption efficiency and pressure control of oxygen generation equipment. The VPSA oxygen generator customized by GNEE for this project uses plateau-specific lithium-based molecular sieves, whose adsorption capacity remains efficient in low-pressure environments; it is also equipped with an adaptive pressure compensation system, which can automatically adjust the adsorption-desorption cycle according to the altitude, ensuring continuous output of oxygen with a purity of ≥93% under the low-pressure condition of 0.05Mpa. During the production stage, the equipment underwent a continuous 720-hour full-load test under a "simulated low-pressure environment at an altitude of 3700 meters", with all parameters far exceeding the design standards.

After the project was put into operation, the oxygen concentration in the plateau area remained stable above 23%, completely solving the pain points of traditional oxygen supply methods such as "large purity fluctuations and intermittent supply". The person in charge of a plateau project stated: "GNEE's VPSA oxygen generator has enabled us to achieve oxygen supply at 3700 meters altitude that is no different from that in plain areas, and its technical reliability and stability have exceeded expectations." This breakthrough is not only an authoritative certification of GNEE's oxygen generation technology under extreme conditions but also fills the technical gap in large-flow diffused oxygen supply in plateau areas, laying a solid "oxygen foundation" for improving people's livelihood and industrial upgrading in plateau regions.
