RPSAA is a new PSA (Pressure Swing Adsorption) system. It’s driven by a rotary type pump where the adsorption vessels with adsorbents are packed.

It extracts air from the refrigerator, separates O2 and N2, discharge O2 and reintroduce N2 into the chamber so as to decrease O2 levels, thus inhibiting bacterial growth and prolonging food shelf-life.

RPASS was verified with concept, patented and exclusively owned by IP Tech.

It is an innovation technology and smart system for huge applications and billions of markets.

It could be used for on-site gas utilization, including

  • gas separation
  • gas generation
  • gas purification
  • gas dehydration
