Based on the high-efficient lithium-based VPSA-O2 adsorbent PU-8, combining with the unique airflow distribution technology, advanced process design and reliable supplementary devices, PIONEER has successfully ensured energy-efficient and large-scale VPSA-O2 plants to provide O2 product at a lower cost.

PIONEER has built up over 100 sets of VPSA-O2 plants and taken the lion share in the field of VPSA-O2 in China. The VPSA-O2 technology won the first prize for Science and Technology Progress by the Ministry of Education.

PIONEER is committed to mutual development with the customers, by providing economical O2 utilization program, optimization of existing plants or on-site gas supply.

Technical Advantages

  • Engineering experiences

    PIONEER has built the most VPSA-O2 plants in China, including the world’s largest VPSA-O2 plant.
  • Low consumption rate

    The power consumption rate of VPSA-O2 plant designed by Pioneer is no more than 0.35 kwh/m3. This rate is the lowest in the world.
  • Leading process design in the world

    PIONEER constructed the first set of radial bed in China. Independently-developed five-bed, air intake and other original process designs have proved obvious advantages.
  • The independently-developed lithium-based adsorbent

    The lithium-based VPSA-O2 adsorbent PU-8 developed and manufactured independently by Pioneer is featured by high selectivity and high working capacity of nitrogen, which is among the best around the world.
  • Mature and reliable running system

    The long-term engineering practice has proved that PIONEER’s VPSA-O2 plants are stable and the supplementary devices are mature and reliable, thus ensuring the continuous production for users.
