S22 CDA (Clean Dry Air) GAS PURIFIER
The PS22 Series Gas 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 series uses ambient temperature adsorption processes designed specifically to provide UHP gas for semiconductor applications. Outlet impurity levels for CO2, H2O and trace impurities including TOCís (C7+), amines, ammonia, siloxanes, sulfurs, refractory compounds, phthalates, carboxylic acids and NOx, are reduced to below parts per billion (ppb) levels.
The risk of impurity breakthrough is minimized when using a regenerable, "self-cleaning" purifier, like the PS22, as opposed to a disposable, "fixed capacity" canister. Experience has shown that inlet impurities found in CDA, for example, can vary greatly depending on ambient atmospheric conditions.
