SED-15ZD-X High-Purity PSA Nitrogen Generation System. Produces 15 Nm³/h nitrogen at 99.99% purity with dew point ≤-40°C. Complete system includes Risen HP-20A 15 kW permanent-magnet VFD screw air compressor, 0.6 m³ buff
مبدأ العمل
Clean, dry compressed air enters two carbon-molecular-sieve adsorption towers A and B. At 0.75 MPa, air flows bottom-to-top through Tower A: oxygen, CO₂, and moisture are adsorbed while nitrogen exits from the top. When Tower A is saturated the system switches to Tower B; Tower A simultaneously depressurises to atmospheric pressure, releasing adsorbed gases(regeneration). The two towers alternate continuously to produce high-purity nitrogen.
