·CMS (Carbon molecular sieve): Toextend the lifetime of PSA nitrogengencrator and raise its stability,wcselect BF from Germany Carbo TechGmbH or Japanese products,which canimprove the adsorbing efficiency andits lifetime.

·Valves: As to the solenoid andpneumatic valves， we select GermanyBurkert or ASco product whichguarantee without malfunction overone million times.

·Controller: Employing GermanySiemens or Japan Omron products toautomatically control the nitrogenproducing process，no operatorrequired.

·Method of backfilling: with the socalled snow-storm-filling method tofill carbon molecular sieves into theadsorber vesscls，maximum density ofmolecular sieves can be acquired,nomore sieves nced in the whole process.

·Nitrogen generator technique:our technique directly comes fromGermany Carbo Tech GmbH, thedesigning of process，inside structureof the adsorption vesscls，valves，andtubes are all German originated whichenable us to offer the lst classtechnique and service to our customers.
