The Pneumatech PPNG7HE is a high efficiency nitrogen generator that is capable of producing flows over 826scfh (13.7cfm). Unlike standard nitrogen generators, the PPNG HE series from Pneumatech constantly monitors in the incoming compressed air and outgoing nitrogen. Your compressed air consumption is reduced when you are not comsuming the maximum N2 produced by the generator, and eliminates compressed air usage when no N2 is being consumed.
The internal Pneumatech part numbers are 8102321182 for nitrogen purity between 95-99.9% and 8102321166 for a 99.999% purity.
The PPNG 7 HE is one of Pneumatech’s premium on-site pressure swing adsorption nitrogen generators for low 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 7 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.
The Nitrogen Generator makes use of Pressure Swing Adsorption (PSA) technology to produce nitrogen by passing pre-treated compressed air through a vessel containing carbon molecular sieves (CMS). The PSA process is inherently a batch process, as the adsorbent bed requires periodic desorption. In order to secure steady flow, the Nitrogen Generator PSA systems contain two adsorbent vessels to provide operational continuity. One vessel is active while the other one is inactive. At the end of each cycle, they switch roles.
Advanced microprocessor controller: PPNG nitrogen generators are controlled by the Purelogic graphic controller. They control the PSA cycle of the generator, the regulation of the nitrogen quality and the protection of the CMS bed:
The inlet air quality is constantly monitored to make sure the inlet requirement is always met:
To guarantee the quality of the outlet gas, the outlet gas parameters are constantly monitored:
