For decades Nitroswing nitrogen generators from Noxerior have been supplying gas for Food & Beverage applications. The latest innovative developments include: possibility of increasing or reducing the gas flow rate directly on site by simply varying the number of modules; and energy savings obtained thanks to the compressed air system that supplies the generators. The modular design of these generators allows to increase the gas flow rates by adding one or more modules. Energy saving is guaranteed by the FlatFlow system, for optimized air distribution. Nitroswing generators offer the lowest air consumption versus the amount of nitrogen actually generated. This development allows to determine the correct size of the compressed air system needed to feed the generator, with lower energy consumption compared to market standards, and notable savings in terms of operational costs.
