Product Description
PSA Nitorgen Generator
Product Description
1, Product Name: PSA Nitrogen Generator
A full installation requires air compressor, refrigerated air dryer, filters, air tank, nitrogen generator
and gas buffer tanks.
We supply full installations but each component, and other optional supply like boosters, high
pressure compressors, nitrogen cylinders or filling stations can also be bought separately.
2, Principle
When the process adopts lifting air, oxygen and nitrogen have different diffusion rate and adsorptivecapacity to separate oxygen from nitrogen on carbon molecular sieve. When air is compressedto 0.8MPa, air source enters in pressure-swing adsorption tower for separation afterbeing purified through dry and oil-water separation process (filter). Oxygen molecules are
diffused and adsorbed in carbon molecular sieve under pressure. Non-adsorbed nitrogen is dischargedfrom outlet of adsorption tower. Oxygen is
desorbed, discharged and purged in adsorption tower under depressurization.
Moreover, adsorbent can be recycled
3, Specifications

Application of Nitrogen Generator
Food packing, Food storing, Electric & Electronic industry, Petrogas & Oil field, Chemicals
& Petro-chemicals, Coal-mine, Metallurgy, Pharmacy, SMT,
Fireresistance, lab, Air driving, and so on...
1,Metallurgy: For anneal protection, agglomeration protection, nitrogenizing, furnace washing
and blowing, etc. Used in fields such as metal heating treatment, powder metallurgy, magnetic
material, copper process, metallic mesh, galvanized wire, semiconductor, etc.
2,Chemical and new material industries: For chemical material gas, pipeline blowing, gas
replacement, gas protection, product transport, etc. Used in fields such as chemical ,urethane
elastic fiber, rubber, plastic, tyre, polyurethane, biological technology, intermediate, etc.
3,Electronic industry: For encapsulation, agglomeration, anneal, deoxidization, storage of
electronic products. Used in fields such as peak welding, circumfluence welding, crystal,
piezoelectricity, electronic porcelain, electronic copper tape, battery, electronic alloy material, etc.
4, Nitrogen Used in Food Industry
1) Beer, wine, fruit spirit and edible oil: use N2 for holding tank, bottle blowing and before
closing capsule to remove O2. It can prevent oxidation, spoilage and fading of noncarbonated
beverage and edible oil.
2) Puffed and fried food: N2 can prevent food fluffy and flavor reversion caused by little water
in the bags. N2 also can make the shape and package beautiful, and food will not be crushed
in transportation.
3) Pastry, bakery food and vitellus-pie: Flushing N2 inside the food bags can prolong freshness
time and prevent food being metamorphose and crushed in transportation.
4) Milk Powder and soyabean milk powder: just use little N2 can prevent or reduce agglomerate
phenomenon of milk powder caused by long-time extrusion storage.
5) Cerea, nut, furit and vegetable: Flushing N2 can prevent pests harming,
and saving little O2 can reduce breathing rate of fruit to make the
fresh effect more obvious.
6) Candy and snack foods: N2 is mainly suitable used in the airtight food bags.
