Edit content
I. Chemical industry, new material industry, automobile tyre
The purity of nitrogen produced by pressure conversion adsorption nitrogen generator is about 98%. It is mainly used for chemical feed gas, pipeline blowing, atmosphere replacement, atmosphere protection, product transportation, etc. It is mainly used in chemical industry, HDMI, rubber, plastics, tyres, polyurethane, biotechnology, intermediates and other industries.

II. Electronics industry
The pressure-changing adsorption nitrogen generator produces nitrogen with a purity of over 99.9% or 99.99%, or obtains high quality nitrogen with a purity of over 99.9995% and a dew point of below-65℃ through nitrogen purification equipment. It is used for the encapsulation, sintering, annealing, reduction and storage of electronic products. It is mainly used in wave soldering, reflow soldering, Crystal, piezoelectric, electronic ceramics, electronic copper tape, battery, electronic alloy materials and other industries.
 
III. Food and medicine industry
The pressure swing adsorption nitrogen generator produces nitrogen with a purity of over 98% or 99.9%. High quality nitrogen can be obtained through sterilization, dust removal, water removal and other treatments to meet the special requirements of this industry. It is mainly applied to food packaging, food preservation, medicine packaging, medicine replacement gas and medicine transportation atmosphere.

IV. Metallurgy and metal processing industry
Nitrogen with a purity of over 99.5% is produced by a pressure-changing adsorption nitrogen generator, and high quality nitrogen with a purity of over 99.9995% and a dew point of below-65℃ is used jointly with nitrogen purification equipment. It is used for annealing protection atmosphere, sintering protection atmosphere, nitrization treatment, furnace washing and blowing gas, etc. Widely used in metal heat treatment, powder metallurgy, magnetic materials, copper processing, wire mesh, galvanized wire, semiconductor, powder reduction and other fields.

V. Other use fields
Besides being used in the above industries, Nitrogen generator is also widely used in many fields such as coal, oil, oil transportation and so on. With the progress of science and technology and the development of society, the use field of nitrogen is becoming more and more extensive. On-site gas production (nitrogen machine) it has gradually replaced traditional nitrogen supply methods such as liquid nitrogen evaporation and bottled nitrogen with its advantages of low investment, low use cost and convenient use.
