Review Of Oajor Events

1979

We devoted ourselves to the R&D and production of PSA oxygen generators in China, participated in the production and export of the first PSA oxygen generator in China, and filled the technical gap in the relevant fields in China

1984

We cooperated with international teams, introduced theoretical support, and officially exported to African countries.

1989

We established a small experimental workshop, initially tried the independent processing of key components of oxygen generators, and accumulated production process experience.

1991

We studied and tested the adsorbent performance of oxygen generators, using Honeywell UOP molecular sieve particles.

1992

We completed the first generation of improved oxygen generator prototypes, achieved stable oxygen production in laboratory environments, and significantly improved technical performance.

1994

We established product quality inspection standards, and strictly controlled and standardized various performance indicators of oxygen generators.

1995

We started the systematic optimization project of key components, and iteratively improved core components such as adsorption towers and valves.

1997

We completed the first round of optimization and upgrading of key components, and further improved the stability of the equipment and oxygen production efficiency.

1999

Established a technical data management system to systematically collect and analyze data in the R&D and production processes.

2000

Frequently participated in technical exchange activities of international companies to learn and draw on international advanced oxygen production technology experience.

2003

Expand the PSA manufacturing base, form a multi-series and multi-specification product matrix, fully support customized scenario needs, and consolidate the leading position in the field of PSA oxygen production.

PSA Oxygen Generator Advantages

PSA oxygen generator is a fully automatic equipment or directly producing oxygen from compressed air by using the zeolite molecular sieve as an adsorbent, utiizing the adsorption capacity of oxygen and nitrogen difference on the molecular sieve surface through the principle of pressure adsorption and declining pressure desorption.

Automatic start

Minimum pressure valve and bypass nozzle for quick start.

Avoid excessive gas and Oxygen molecular sieve damage.

Outstanding reliability

Rugged design.

Continuous operation (24 hours a day, 7 days a week).

It will not stop operation due to interruption of air supply.

Monitor

Remote start stop.

Modbus, Profibus Fieldbus and Ethernet.

MARTLINK is a smart star.

Automatic adjustment, stable purity

According to the required oxygen pressure and purity automatically adjusted.

The purity adjustment is extremelyconvenient.

Failed oxygen blowing.

Device runs on its own

Standby mode is maintained when oxygen is not needed.

Cycle Time Modulation Algorithm = Extended Cycle in Oxygen Demand Hours Time = Reduced air consump- tion during hours of oxygen demand.

High quality oxygen molecular sieve

High density.

Compact spring loaded.

Top/bottom balance.

Protected by a dedicated pressuresensor.

Plug and play

Just dry the compressed air supply.

Plug and play.

No special installation and commissioning are required.

Fully automatic and monitored oxygen sensors are standard.

Easy to maintain.

Other advantages

Provide up to 93%, 95%, 96%, 97%, 98%, 99%

Used in medical fields (such as wards, emergency rooms and operating rooms)

Industrial fields (such as mining, chemical industry, breeding, electronics, papermaking and other industrial processes)

Environmental protection field (such as waste gas treatment, etc.)
