Principles:
PSA nitrogen generator uses carbon molecular sieve as sorbent, produces nitrogen by making use ofthe PSA principle. Under certain pressure, carbon molecular sieve has different oxygen/nitrogen
adsorption capacity, i.e. much more oxygen adsorption capacity than nitrogen adsorption capacity.
PLC controls pneumatic valve on/off to realize two towers alternate adsorption and desorption as per
pressure change, carries out oxygen/nitrogen separation and produces nitrogen with desired purity.
