Noxerior s.r.l.

Noxerior s.r.l.

Our roots go back to the early seventies of last century, when the preceding company initiated with the sale of welding wires as main activity. During the first half of the eighties this company started to import PSA oxygen generators from the US for welding applications. Soon afterwards it was decided to develop and manufacture own PSA oxygen generators in order to meet the regulations valid for the European market. In 1990 the production of PSA nitrogen generators was initiated as well. Our large heavy-duty twin-tower PSA oxygen generator range stands for a reliable and efficient oxygen supply. The application range for our products varies from nitrogen for food & beverage industry to high quality medical oxygen for intensive care application in hospitals. Currently we are not only active in our traditional markets for standard nitrogen and oxygen generators for industrial and healthcare applications in almost all corners of the world.

The nitrogen generators and oxygen generators from NOXERIOR combine first-class quality with a competitive price and low cost-of-ownership. If you are looking for a membrane nitrogen generator or a PSA nitrogen generator we have three different product lines for you, all applying NOXERIOR proprietary technology. Our unique modular PSA oxygen systems and medical oxygen concentrators offer you an unmatched flexibility and have set new market standards.

In November 1997 the Messer Group from Germany, one of the leading companies for industrial gases at the time, acquired the entire gas generator business and founded our actual company.

During the reorganization process of the Messer Group in 2001, our company was acquired by Innovative Gas Systems, Inc. from the US as part of a Management Buy-Out by the former Messer companies. During the IGS’ period we started to become active in the EPC market for the Oil & Gas and Mining Industry. Subsequently our company name was changed in IGS Italia in July 2004.

Respectively in 2004 and 2007 we introduced our patented / patent pending modular PSA nitrogen and oxygen systems, which we are offering to the market under the brand names NITROSWING® and OXYSWING®. The medical version of this product was certified as Class IIB medical device to the MDD 93/42/CEE in 2008. In 2009 the Italian Ministry of Health issued the Certificate of Free Circulation for our OXYSWING® medical oxygen generators. NOXERIOR was also one of the founding members of MEDIGHAM, the International Association of Manufacturers of Medical Gas Generators for Hospitals (

In March 2014 we changed ownership again and our company name was changed in NOXERIOR s.r.l. Our new company name is a contraction of the words “nitrogen”, “oxygen” and “superior” to ensure that our image and name accurately reflect what we do.

Our quality management system has been certified to ISO 9001 since 2004 and to ISO13485 since 2007. Our environmental management system has been certified to both ISO 14001 and EMAS since 2006.

Currently we are not only active in our traditional markets for standard nitrogen and oxygen generators for industrial and healthcare applications in almost all corners of the world, but especially the supply of complex custom-engineered nitrogen and oxygen plants including all necessary documentation has become a substantial part of our business during the last years. Since 2010 we have started with the supply of custom-engineered packages for the generation of instrument air as well.

In 2016, NOXERIOR becomes part of NOVAIR Group, French manufacturer specialized in the production of on-site industrial and medical gas systems since 1977. The Group is proud to offer the largest pool of expertise worldwide in on-site gas systems.

Our prime aim is to establish long-term professional relations based on transparency and reliability.

Behind all our activities lies trust: the trust our customers have in our ability to meet their specific needs in terms of both quality standards and agreed delivery terms.

Our team of highly skilled professionals provides all the flexibility required to develop and design our gas generation systems.

Commitment towards understanding the needs of our customers drives us to constantly look for the best possible solution for each specific gas application and operating condition.

But our advice is not restricted to our products alone. Wherever possible, we also suggest improvements regarding the use of the produced gas in order to allow our customers to increase efficiency and to reduce costs
