PS22 CDA (Clean Dry Air) Purifiers

PS22 CDA Gas Purifier

The CDA MegaTorr Purifiers are enhanced, optimized designs providing sub-ppb performance. SAES Pure Gas has drawn on years of experience in Ultra-High Purity (UHP) piping design, advanced process material analysis and state of the art integrated control systems to develop this family of purifiers to meet the needs of low capital cost, high reliability and high performance.
The PS22 CDA Purifiers use ambient temperature adsorption processes designed specifically to provide UHP CDA for lithography, inspection, or metrology semiconductor applications. Outlet impurity levels for CO2, H2O and trace impurities including TOC’s (C7+), amines, ammonia, siloxanes, sulfurs, refractory compounds, phthalates, carboxylic acids and NOx, are reduced to below parts per billion (ppb) levels with these Clean Dry Air Purifiers.
