Atlas Copco Compressors Launches Complete Range of Nitrogen and Oxygen Generators


Atlas Copco’s Industrial Air Division has introduced three ranges of nitrogen and oxygen generators allowing manufacturers to generate their own gas supply on site, providing greater economies of scale that result in additional cost savings.

On-site gas generation is part of a sustainable and cost-effective management program that allows companies to reduce costs without sacrificing quality-control issues, such as gas purity, regardless of application end use. It also provides additional benefits when compared to delivery of gas cylinders or bulk liquid gas supplies, including the elimination of administrative work associated with order processing and invoicing and the physical demands and costs related to frequent truck deliveries to a facility’s cryogenic tanks.  

“Our customers can dramatically increase their productivity with the use of these new gas generators,” said Robert Eshelman, vice president of Atlas Copco Compressors Industrial Air Division. “We’re always looking for innovative ways to help our customers discover potential savings through economy of scale; combining compressed air systems with nitrogen or oxygen production is a great way to serve these specific needs.”

Membrane nitrogen generators for easy, cost-efficient gas generation

Membrane nitrogen generators provide easy, cost-efficient gas generation
Atlas Copco’s membrane nitrogen generator (NGM) uses membrane air separation to produce nitrogen and, due to its high efficiency and reliability, is ideal for applications such as fire prevention, tank and pipeline cleaning, and many other oil, gas, mining and marine applications. A bundle polymer fiber acts as a membrane that allows nitrogen to pass and other gases (such as oxygen, water vapor and carbon dioxide) to permeate. Compressed air is applied through an inlet and the enriched nitrogen is released through the discharge of the nitrogen generator. Membrane technology generates nitrogen with an adjustable purity and flows up to 17500 SCFH.
PSA nitrogen generators for the highest purity
For applications that demand exceptional nitrogen purity (up to 99.999 percent), the Nitrogen Generator (NGP) with Pressure Swing Adsorption (PSA) technology uses a carbon molecular sieve-type desiccant to absorb oxygen molecules from compressed air. The NGP has two linked towers that work in conjunction to produce an almost continuous flow of nitrogen gas, resulting in nitrogen purity levels reaching 99.999 percent for flows up to 39000 SCFH. Typical Nitrogen Generator applications are widely used in packaging, plastic molding, metallurgy, purging analyzers, electronics, fruit storage and food and beverage applications and industries.
PSA oxygen generators for reliable, on-site oxygen
Oxygen is vital to numerous processes in laboratories, wastewater treatment, fish farming and ozone production to name a few. The Atlas Copco OGP oxygen generator also uses PSA technology, with zeolite pellets that act as an adsorbent, generating oxygen output that results in an adjustable purity level between 90 and 95 percent, at flows up to 7000 SCFH.
On-site nitrogen and oxygen as part of a total solution
Atlas Copco’s on-site gas generators, which can be directly combined with an existing compressed air installation, provide companies with independent supplies of nitrogen and oxygen that results in savings through the elimination of operational and administrative costs that come with bulk and cylinder gas delivery. These three ranges of nitrogen and oxygen generators offer precision flows and purity levels that different industrial applications demand.
