Achieving ultra-pure nitrogen through purification

A nitrogen purification system is part of an on-site nitrogen generation system. It relies on a small amount of hydrogen to remove residual oxygen from nitrogen gas produced by a nitrogen generator. The catalytic reaction ensures that nitrogen gas achieves near-absolute purity, making it suitable for critical applications in industries such as electronics, chemicals, laser cutting and more. By generating  ultra-pure nitrogen with a nitrogen generator+purification system rather than with just a generator, users can  size the compressor and generator of their gas generation system smaller and significantly reduce  feed air consumption.

Key Features

Catalytic oxygen removal

At the core of the PPNG 12-235 DX is its catalytic purification system, designed to eliminate residual oxygen from nitrogen gas. This process works by introducing a controlled amount of hydrogen, which reacts with oxygen to form water vapour, effectively purifying the nitrogen stream. The result is consistent nitrogen purity levels of up to 99.9999%, making the system suitable for the most oxygen-sensitive applications, such as electronics manufacturing, laser cutting, and chemical processes. This high level of purity helps protect end products and ensures process stability.

Key Features

Precision hydrogen dosing

The PPNG 12-235 DX features an automatic hydrogen dosing system, designed to deliver precise amounts of hydrogen based on the oxygen content in the nitrogen stream. This fine-tuned control ensures optimal reaction efficiency, allowing residual oxygen to be completely removed without excess hydrogen consumption. As a result, the system maintains stable nitrogen purity levels, minimises hydrogen usage, and prioritises process safety. Users can trust the system to deliver purity consistently, without needing frequent adjustments or supervision.

Key Features

Advanced Purelogic Touch controller

The PPNG 12-235 DX is equipped with the Purelogic Touch Controller, offering full automation for safe and reliable operation. The controller continuously monitors key parameters, such as nitrogen purity, pressure, and flow, ensuring the system operates at peak performance at all times. It also features automatic standby modes, which reduce energy consumption during periods of low nitrogen demand, helping lower operating costs. Built-in safety safeguards protect gas quality and prevent operational issues, giving operators peace of mind and minimising the risk of production downtime.
