The PPNG 6–90 HE uses PSA technology to separate nitrogen from compressed air through Carbon Molecular Sieves.

 

Step 1 – Compressed Air Intake
Clean compressed air enters the nitrogen generator.

 

Step 2 – Gas Separation
The air passes through vessels containing high-efficiency Carbon Molecular Sieves.

 

Step 3 – Oxygen Adsorption
The CMS selectively adsorbs oxygen and other gases while nitrogen passes through.

 

Step 4 – PSA Regeneration
The vessels alternate between pressure levels, regenerating the CMS for continuous nitrogen production.

 

Step 5 – Purity-Controlled Delivery
Nitrogen is delivered at the selected purity, flow, and pressure.

 

Step 6 – Demand Optimization
The Variable Flow Saver adapts the PSA cycle and feed-air intake during lower demand to reduce unnecessary energy consumption.

The PPNG 6–90 HE combines efficient PSA technology, intelligent controls, and automatic purity management for dependable on-site nitrogen generation.

 

High-Purity Nitrogen

Produces nitrogen with selectable purity up to 99.999% for demanding applications.

 

Variable Flow Saver

Reduces energy consumption during low nitrogen demand and can bring air consumption down to zero when nitrogen is not required.

 

High-Efficiency CMS

Advanced Carbon Molecular Sieves support efficient nitrogen separation and lower operating costs.

 

Automatic Purity Control

Automatically regulates nitrogen flow, pressure, and purity to maintain specified gas quality.

 

Zirconia Oxygen Sensors

Precisely monitor oxygen levels to support consistent nitrogen purity.

 

Purelogic Touch Controller

Provides advanced control and monitoring of nitrogen flow, pressure, purity, and feed-air quality.

Frequently Asked Questions

Find quick answers about the PPNG 6–90 HE PSA nitrogen generator, including purity, capacity, efficiency, technology, and applications.
The PPNG 6–90 HE offers selectable nitrogen purity from 95% up to 99.999%, allowing users to select gas quality according to application requirements.
It uses Pressure Swing Adsorption (PSA) technology. Carbon Molecular Sieves selectively adsorb oxygen and other gases from compressed air, allowing nitrogen to pass through as the product gas.
The Variable Flow Saver can reduce energy consumption by up to 40% during low-demand periods by adapting the PSA cycle and feed-air intake.
The PPNG 90 HE can deliver up to 264.3 Nm³/h at 95% purity, 127.7 Nm³/h at 99.5% purity, or 37.2 Nm³/h at 99.999% purity, according to the manufacturer’s specifications.
The specified inlet pressure range is 4–13 barg, with an inlet temperature range of 5–60°C.
Yes. Zirconia oxygen sensors and the Purelogic Touch controller support automatic monitoring and regulation of nitrogen purity, flow, and pressure.
Yes. As an India-based distributor, Atcorp can help evaluate your required nitrogen purity, flow, pressure, and application to identify a suitable PPNG configuration, along with product supply and service support.
