The complete high-flow nitrogen generator

In this chapter discover features of the NGP and their benefits.

Self-protective monitoring of the feed air quality

• Temperature

• Pressure

• Pressure dewpoint

• Automatic feed air blow-off in case of contamination

Electronics
  • Advanced Elektronikon® Touch controller with large HD color touchscreen offers easy gas purity selection, purity alarm, feed air monitoring and interception, and connectivity options.
  • Automatic start-up and stand-by mode allow for easy operation and avoid energy waste.
  • Application protection system ensures only gas that meets the minimum purity requirement will reach your application.
  • The generator and its software are designed to utilize the premium Carbon Molecular Sieve adsorbent with maximum efficiency.
Valves

The valves of a PSA generator switch every minute on average. Because of their intensive use, these valves play an important role in the reliable operation of the generator and the continuity of your production. That is why the NGP⁺ features in-house qualified, heavy-duty valves with a long service life.

  • A: delivery valve – 1. automated valve which will only open when the generator is operative and 2. The nitrogen purity is ok 3. The nitrogen mixing vessel threshold is above it’s minimum threshold.
  • B: Pressure reducing valve – 1. Matches the exact nitrogen pressure with the required demand 2. Stabilizes the nitrogen outlet pressure.
  • C: Manual flow control value – Allows to adjust the nitrogen flow rate, based on the input from the flow transmitter, in order to keep the purity at level. Without this valve the purity would drop and the unit would go into flushing mode all the time.
  • D: Outlet check valve – Prevents backflow from the process.
Oxygen analyzer

Oxygen analyzer with high accuracy and long service life for reliable purity measurement

Highest quality adsorbent/CMS

• High density due to packed bed technology

• Top/bottom equalization

• Protected by dedicated pressure sensor

• Low air consumption

Automatic start-up

• Minimum pressure valve with bypass nozzle for fast start-up.

• Eliminates risk of overflow and carbon molecular sieves (CMS) damage.

Nitrogen flow meter

The nitrogen flow transmitter is used

  • to visualize the N2 flow coming out of the generator
  • as a mandatory input for the energy saving cycle extension at reduced N2 demand
  • to stop the generator when there is no demand

High accuracy: Allows for precise tuning of the manual flow control valve

Rugged, solid metal housing IP66/67 and NEMA4X: Provides excellent protection of the internal electronics against humid environments.

Silencer

Significantly suppresses the noise generated during the following steps:

  • The blow off and regeneration phase of one of the vessels
  • The exhaust of feed air with too high moisture content
  • The exhaust of produced nitrogen with incorrect purity

Absorptive type silencer: Provides excellent noise attenuation. Due to low noise level the NGP can be used as a workplace unit (in permitted according to the safety measures).
