Stockholm, Sweden—Atlas Copco, an industrial group with world-leading positions in compressors, expanders and air treatment systems, construction and mining equipment, power tools and assembly systems, has introduced three ranges of nitrogen and oxygen generators for on-site gas generation.

With these innovative gas generators, companies can expand their existing compressed air installation to generate their own nitrogen and oxygen, as an independent supply of on-site gas can realize significant economies of scale as well as save on operational costs.

The new range of Atlas Copco on-site gas generators are designed to meet the highest purity standards and run economically for both large and small applications.

According to Atlas Copco, on-site gas generation is more sustainable and cost-efficient than gas delivered in cylinders or bulk liquid supply, as it eliminates the operational and administrative costs of ordering, transporting, storing and delivering the bottles or bulk liquid into cryogenic tanks. With an independent supply of nitrogen and oxygen, companies’ gas demand is always met in time, at the lowest cost.

Atlas Copco Industrial Air Division vice-president of marketing Koen Lauwers says “With these new ranges of gas generators, our customers will dramatically increase their productivity. We help them to discover untapped saving potentials through economy of scale: combining their compressed air systems with the production of nitrogen and/or oxygen, serving their specific needs.”

Membrane nitrogen generators

Atlas Copco’s membrane nitrogen generator—the NGM (see photo above)—is, thanks to its high efficiency and reliability, ideal for applications such as fire prevention, tire inflation,  tank and pipeline cleaning, and many other oil and gas, mining and marine applications. The NGM uses membrane air separation to produce nitrogen. A bundle polymer fiber acts as a membrane that allows nitrogen to pass and other gases (like oxygen, water vapor and carbon dioxide) to permeate. Compressed air goes in at the inlet and enriched nitrogen comes out at the other end of your nitrogen generator. Membrane technology generates nitrogen with an adjustable purity and flows up to 500 m³/h.

PSA nitrogen generators

For those applications that demand high purities of nitrogen (up to 99.999%), the Nitrogen Generator (NGP) with PSA technology is the recommended solution. Based on the Pressure Swing Adsorption (PSA) technology, carbon molecular sieves adsorb oxygen molecules from compressed air. The Nitrogen Generator has two connected towers that work together to produce an almost continuous flow of nitrogen gas. The result: nitrogen purity levels up to 99.999% for flows up to 1100 Nm³/h. Typical applications of the NGP are packaging, plastic molding, metallurgy, purging analyzers, electronics, fruit storage and food and beverage.

PSA oxygen generators

Oxygen is vital to processes in the medical world, in waste water treatment, fish farming and ozone production. The OGP oxygen generator also makes use of PSA technology, with zeolite pellets that act as adsorbent. The output is oxygen with an adjustable purity between 90% and 95%, at flows up to 200 Nm³/h.

On-site nitrogen and oxygen as part of a total solution

Atlas Copco now offers on-site gas generators which can be directly combined with an existing compressed air installation. With an independent supply of nitrogen and oxygen, companies can start saving on the operational and administrative costs of bulk and cylinder gas delivery. These 3 ranges of nitrogen and oxygen generators offer exactly the flows and purities that different industrial applications need. This way, Atlas Copco becomes a one-stop-shop for compressed air, gas and service.
