Atlas Copco has added a new model to its range of pressure swing adsorption (PSA) nitrogen generators. The NGP 130+ offers a nitrogen flow of 37 Nm³/h to 264 Nm³/h, depending on the selected purity. The NGP+ range is now available in all flow sizes from 1.9 Nm3/h to 2 871 Nm3/h (at reference conditions).

“Generators are most efficient at full load. The NGP 130+ ensures that no matter the capacity request, customers can always operate with maximum efficiency, and that they don’t need to size up or work with a parallel installation,” says Atlas Copco Industrial Air Division product manager: industrial gases Ben Christianen.

The company has also introduced next-generation control and automation technology to its smaller NGP+ units. This includes the nitrogen purity check, which continuously monitors the nitrogen output and reroutes it when its purity does not meet the selected standard. On the inlet side, the feed air check blocks air that is of subpar quality from entering the generator and possibly compromising its operation.

The Variable Cycle Saver algorithm optimizes the PSA cycle during lower demand and in colder temperatures, offering up to 40% additional energy savings. All NGP+ 8-130 models feature the Elektronikon touch controller with easy gas purity selection and advanced monitoring and connectivity options.

Optional features include a room oxygen alarm, the ability to work in very low ambient temperatures and the ability to produce ultra-dry nitrogen.

The new NGP+ 8-130 comes with the same modular build – with extruded aluminum tubes – as the existing generation, and is designed to be compact and durable.

The generator and its software are designed to use the Carbon Molecular Sieve adsorbent with maximum efficiency to ensure minimal air consumption per unit of nitrogen generated, which helps ensure low total cost of ownership.
