Pneumatech PPNG15HE Nitrogen Generator, 95%-99.999% Purity, 176-1652 SCFH Flow, High Efficiency Model

The Pneumatech PPNG15HE is a high efficiency nitrogen generator that is capable of producing flows over 1652 scfh (27.5cfm). 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 8102321307 for nitrogen purity between 95-99.9% and 8102321281 for a 99.999% purity.

The PPNG 15 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 15 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:

  • Pressure swing adsorption cycle control: The PSA cycle algorithm will be altered depending on the level of consumed nitrogen. This way, less compressed air is needed to feed the generator and energy is saved when the generator is not running at full load. This algorithm also compensates for altering ambient conditions (thus the generator uses less compressed air at lower temperatures) and altering purity settings (the generator will use less compressed air at lower purity settings). When no nitrogen is consumed, the generator will enter stand-by mode and not use any compressed air at all.
  • Automatic start-up: Automatic start-up enables the user to start the generator with the push of a button. The generator will fill the nitrogen receiver with a specific flow which will result in the fastest start-up procedure possible.
  • Guaranteed purity: When the nitrogen purity is less than requested, the flushing mode will shut off the nitrogen flow to the user and direct it over the flushing nozzle. This way, the purity will be recovered as fast as possible.

The inlet air quality is constantly monitored to make sure the inlet requirement is always met:

  • Inlet PDP sensor
  • Inlet temperature sensor
  • Inlet pressure sensor
  • Inlet pressure indicator
  • Inlet air purge valve: to flush the inlet air when the inlet PDP is worse than requested.
  • Pilot air connection

To guarantee the quality of the outlet gas, the outlet gas parameters are constantly monitored:

  • Outlet pressure sensor
  • Outlet pressure indicator
  • Outlet PDP sensor (optional)
  • Outlet flow meter
  • Nitrogen purity sensor
