The PPNG 6-68 HE series is Pneumatech’s premium on-site PSA Nitrogen Generator for low to medium flows, with best-in-class performance and the most complete scope of supply. The generator has outstanding air factors at full load thanks to the use of highly-efficient Carbon Molecular Sieves (CMS) and back-flow pressurization. The air consumption is also optimized at reduced nitrogen flow or pressure demands, thanks to the advanced energy saving algorithm, which automatically adjusts the cycle times of the generator.
The control and monitoring capabilities of the PPNG 6-68 HE are truly impressive. Purity is guaranteed at all times by opening the consumer valve only at the requested purity level and flushing nitrogen when purity is not reached. Feed air quality is controlled by monitoring temperature, pressure and PDP. The feed air is blown off in case of contamination. All risks of possible CMS damage are eliminated thanks to the automatic start-up feature.
