Nitrogen Generators, Oxygen Generators, Air separation solutions, Compressed gas solutions

Rongchen possesses much experience in producing gas generation and auxiliary equipment, including but not limited to PSA nitrogen/oxygen generator, gas purification equipment, VPSA oxygen generator, etc. We have developed long-term cooperation with international well-known component suppliers to ensure the stable performance of our products, which can support continuous operation of over 8000 hours without error, and they also will not stop operating due to interruption of gas supply. At the same time, our products are also equipped with a real-time display of gas production parameters, which allows you to visualize the gas output capacity, purity and other information. All parameters can be easily adjusted according to your specific need of nitrogen volume, air pressure and purity, if the output gas is unqualified, the remaining gas can be fully discharged in order not to cause pollution to subsequent production. The operation of our equipment is also very simple, only dry atmospheric air is needed as raw material. When you are not at the production site or need to operate several machines at the same time, it is possible to automate the production with a preset program or remote start/stop through the mobile phone control system.

  • Nitrogen Generators

    Nitrogen Generators

    PSA nitrogen generation is a technology to separate nitrogen from air by the adsorption ability of carbon molecular sieve under pressure by air compressor. After the air is compressed and purified (removing the oil, water and dust, etc.) before transferring into the absorption tower filled with carbon molecular sieves (CMS), the oxygen molecule will be adsorbed by carbon molecular sieve, while nitrogen molecules are too large so that they will not be adsorbed.

    Nitrogen capacity: 3-5000Nm³/h (standard conditions)
    Nitrogen purity: 90%-99.9995% (oxygen-free nitrogen)
    Nitrogen pressure: 0.1-0.8Mpa (stable and adjustable pressure)
    Nitrogen dew point: -40°C to -70°C (atmospheric pressure)
  • Oxygen Generators

    Oxygen Generators

    Our PSA oxygen generator can separate oxygen from compressed air utilizing zeolite molecular sieve (ZMS) under pressurization. For PSA oxygen generator, the compressed air is first purified to remove the moisture, oil and dust. Then the purified air will pass through adsorption tower filled with ZMS. As nitrogen has a higher diffusion rate in ZMS pores, the sieve will adsorb the nitrogen and moisture over oxygen, allowing the oxygen to pass as product gas at pressure. After de-pressurizing, the sieve releases adsorbed gases into the atmosphere, and the process can then be repeated.

    Oxygen capacity: 5-200Nm³/h
    Oxygen purity: 90%-94%
    Oxygen pressure: 0-0.5Mpa
    Oxygen dew point: -40℃ (atmospheric pressure)
  • Auxiliary Equipment

    Auxiliary Equipment

    Air compressor is essential in the preparation process of gas generation, it is used to compress, filter, dry and cool the ambient air. The impurities, moisture and pollutants in the atmospheric air will be removed before the separation process of nitrogen and oxygen, so that the compressed air will have a higher quality and purity.

    Free air delivery: 0.4-101m³/min
    Oil content: 3ppm
    Air temperature: ambient temperature to +35°C
    Cooling method: air cooling
    Rated power: 4kW-750kW
    Transmission: direct drive/belt drive
