This equipment produce Nitrogen gas on the principle of Pressure swing adsorption.Nitrogen can be used as the productive gas.so the equipment can be used in many industries,such as heat treatment,metal metallurgy,food packaging,electronics, petrochemical, aerospace and other dominating fields. Model:XRFD Nitrogen purity:95%,98%,99%,99.5%,99.9%,99.99%,99.999%,99.9995% Nitrogen flow rate:5-2000Nm3/hr The gas seperation of PSA takes such advantages as different gas has different adsorbing capacity in the CMS under different pressure to separate gases. PSA nitrogen generators are designed based on the PSA theory. They possess the properties of simple technology, low space requirement, quick start up, simple maintenance&operation, good applicability, high automation, low operation cost, low investment, etc.
