1. Metallurgy, metal processing industry
The 99.5% nitrogen gas produced by PSA nitrogen generator gets through the purification equipment to reach 99.9995% purity with dew point lower than -65 ℃, using for annealing protective atmosphere for, sintering atmosphere, nitrogen treatment, wash and purge gas furnace, etc. The gas is also widely used in metal heat treatment, powder metallurgy, magnetic materials; copper, metal mesh, galvanized wire, semiconductor, and powder restore areas.
2. Chemical and new materials industry
To produce nitrogen gas purity from higher than 98% or required purity through PSA nitrogen generator. Mainly used as chemical raw materials gas, pipelines purge, the atmosphere replacement, the atmosphere protection, and product delivery, etc, and also used in chemical industry, spandex, rubber, plastics, tire, polyurethane, biotechnology, and intermediates, etc.
3. Food, pharmaceutical industry
To produce nitrogen gas purity from higher than 98% or99.9% through PSA nitrogen generator, and through degerming, dust removal, and the water treatment, to meet the special requirements of the industry for high-quality nitrogen. Mainly used in food packaging, food preservation, medicine packaging, medicine replacement gas, and the atmosphere of medicine transmission.
4. Electronics industry
The 99.9% or above 99.99% nitrogen gas produced by PSA nitrogen generator gets through the purification equipment to reach 99.9995% purity with dew point lower than -65 ℃, used for packaging of electronic products, sintering, annealing, reduction, storage, etc, also used in wave soldering, reflow, crystal, piezoelectric, electronic ceramics, electronic copper belt, batteries, electronics and other alloy materials industries
5. Other using fields
Apart from the use of in these machine industries, in coal, petroleum, and oil, in many other fields of transport, nitrogen has also been widely used. With the advancement of technology and social development, the nitrogen is used in more and more extensive areas; on-site gas (nitrogen generator) for its low investment, the low cost of use, ease of use has been gradually replaced the liquid nitrogen evaporation, bottled nitrogen and other traditional methods for nitrogen.
