Atlas Copco has announced the addition of nine energy-efficient, high capacity models to its NGP+ nitrogen generators range. The expanded range now offers the capability to deliver on-site nitrogen at flows ranging from 5.2 l/s (19 Nm3/h) to 797 l/s (2870 Nm3/h), with purity levels up to 99.999% and a potential 50% reduction in running costs.
Mark Ranger, UK Business Line Manager for Oil-free Air at Atlas Copco Compressors commented: “In specific applications, such as the oil and gas industry that typically require 95 to 99% nitrogen purity, reported gas price decreases of as much as 75% have been achieved. What is more, users in other sectors, such as rubber, metal production and general industry, are able to refine the actual purity level required for any given application while benefitting from optimum economic operation.”
On-site NGP+ generators offer a more sustainable and cost-efficient solution than reliance on gas delivered in cylinders or bulk liquid supply, which requires transport, handling and resulting administration. Operating with the latest pressure swing adsorption (PSA) technology, the plug-and-play generators, when connected to an existing clean, dry compressed air installation, offer an independent, reliable and flexible supply of premium grade nitrogen at the highest purity levels.
NGP+ generators have been designed from the outset to protect the process application and the users’ equipment investment. By default, NGP+ generators feature an automatic off-spec check purity control so that nitrogen with a purity level less than the pre-set threshold can never reach a sensitive application. At the same time, feed air conditions such as temperature, pressure and pressure dewpoint are continuously monitored by fail-safe sensors. When not matching the generator requirements, the feed air is blown off automatically before entering the machine to eliminate the risk of contamination and damage to components.
