Fenghua nitrogen-making is the famous equipment supplier in normal temperature air-separating field. Fenghua Co. has been engaged in researching and developing technical equipment of separating nitrogen from air by pressure swing adsorption(PSA) since 1980s, is one of the earliest enterprises at home which exploits the purification equipment of PSA nitrogen generators. With 20 years special nitrogen-making, technology has innovated and improved constantly. Company's patent of full-automatically hydrogen-adding technology rewritten the history of purification of nitrogen, manual adding hydrogen of domestic, thus it changed the flaw that it can't adjust in time when adding the hydrogen artificial, sometimes it will be too much while sometimes will be lack when adding hydrogen, the content of high purification nitrogen and oxygen is unstable, the consumption of the oxygen is great, and it can’t satisfy the request of using nitrogen and lead to the fact that the product quality is unstable. It’s adopted extensively by the colleague. The epoch-making development and application of technology makes the technique of air-separating nitrogen-making of Fenghua lead in the world in air-separating nitrogen-making field of the unique molecules sieve fitting technology of the company, unique air cylinder compress tightly structure, system full-automatically operating, etc.. The product is energy-efficient, simple and reliable and exports to all over the world. The customer spreads all over each field, such as petroleum, chemical, coal, electron, food, metal, communication, medicine, etc.. The cautious management of the company makes the products with excellent quality. Good after-sale service especially makes Fenghua win universal praise.

Product:

The company forms the products of PSA nitrogen generators, separation membrane nitrogen-making machine, CDZ gas purification equipment, air compressed purification, etc. series.
