On-site nitrogen generation

Paul Clark, business line manager of Atlas Copco’s Industrial Air division in the UK, comments: "An on-site nitrogen installation with NGP+ will dramatically increase our customer’s productivity and lower their energy consumption. The NGP+ is our latest generation pressure swing adsorption generator and, when integrated into an energy-efficient compressed air network, it uses 50% less energy than the standard type of installations currently seen in the industry.”

The NGP+ works with PSA technology: carbon molecular sieves (CMS) that adsorb oxygen molecules from compressed air. By using sieves that are perfectly tuned to a compressed air network, the NGP+ adsorbs more oxygen for the same input of compressed air. Its sensors and monitoring functions ensure reliability, optimal performance and energy-efficiency. Available in flows from 1.6 to 172L/s, the NGP+ also comes with extensive features to easily adjust the nitrogen purity and pressure, as well as enabling remote monitoring. 

The NGP+ complements Atlas Copco’s existing range of on-site gas solutions, including both nitrogen and oxygen generators. In nitrogen generators, both membrane and PSA technology are available and in both technologies, Atlas Copco offers low-investment entry models as well as high-end models that ensure the lowest energy cost. Especially for laser cutting and bottle filling applications, Atlas Copco has launched a complete package including compressors, air treatment and nitrogen generators that delivers nitrogen at 350 bar.
