Nitrogen Purifier: Atlas Copco NPH 20-400

A new way to achieve high-purity on-site nitrogen generation

The Atlas Copco NPH 20-400 redefines nitrogen generation with an innovative two-stage process, offering unmatched efficiency and purity. Designed for industrial applications, the NPH system combines with a nitrogen generator to deliver ultra-pure nitrogen while significantly reducing energy usage.

How it works

An onsite nitrogen generator includes an air compressor, a nitrogen generator and the required storage and treatment equipment. The air produced by the compressor is processed by the nitrogen generator, removing the oxygen and leaving only nitrogen. At this point the NPH then steps in to purify the nitrogen.

The on-site nitrogen generator produces nitrogen at 99.9% purity. Using a small amount of hydrogen to remove residual oxygen, the NPH boosts the purity to over 99.999%. This two-step process reduces energy use and enhances production efficiency.

Key benefits

  • Energy savings

    • Requires 40% less compressed air than producing the same purity by generator only, translating to substantial energy savings.
    • Supports a smaller carbon footprint with reduced energy consumption.
    • Enables the use of smaller compressors and generators.
  • High performance

    • Guarantees nitrogen purity levels of 99.999% and up to 99.9999%.
    • Doubles the capacity of your existing nitrogen generation system.
    • Operates without straining your electrical system.
    • Produces water and heat as byproducts, ensuring no harmful emissions.
  • Reliability

    • Delivers a continuous supply of ultra-pure nitrogen.
    • Requires minimal maintenance, reducing downtime and operational costs.
    • Seamlessly integrates with traditional gas delivery systems.
