UNISSI Psa Generator

PSA Technology (PSA) is most commonly used non-Cryogenic oxygen and Nitrogen production process, most effective for small and medium capacities. The process operates by using Two Columns filled with absorbent, a molecular sieve. Clean and dry compressed air enters the first column; unwanted molecules are being trapped while the product gas is allowed to pass through. When the active column is saturated the air flow is redirected to second column. The saturated column depressurizes allowing the molecular sieve to completely regenerate. The process is repeated continuously.
