PSA (Pressure Swing Adsorption) N2 Technology
Why are Parker PSA Systems Superior to
Parker’s nitrogen gas generators separate nitrogen from air, utilizing pressure swing adsorption technology. Air entering the generator consists of 21% oxygen and 78% nitrogen. The gas separation process preferentially adsorbs oxyen over nitrogen using carbon molecular sieve (CMS), thus enabling the N2 to pass through as a product gas at pressure.
High performance and long bed life all start with good bed design, gas distribution and careful attention to air velocities and mechanical stresses on the carbon molecular sieves.
Both one and two bed units are specially charged with carbon molecular sieve (CMS). A solid state programmable controller simply operates the process valves on a cyclic basis, with built-in logic for automatic stop/start. Parker production and purity remain constant, regardless of the customer peak usage demands, by utilizing an automatic flow control valve. A continuous monitoring oxygen (O2) analyzer, with alarms and shutdown, is standard equipment.
