The PMNG 4–40 HE uses membrane separation to continuously produce nitrogen from treated compressed air.

 

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

 

Step 2 – Membrane Separation
Compressed air passes through hollow polymer membranes.

 

Step 3 – Selective Permeation
Oxygen and other faster-permeating gases pass through the membrane walls.

 

Step 4 – Nitrogen Concentration
Nitrogen remains within the membrane fibers and becomes concentrated.

 

Step 5 – Nitrogen Delivery
The generated nitrogen is supplied continuously at the selected purity.

 

Step 6 – Purity Adjustment
The system allows purity to be selected between 95% and 99.5% according to application requirements.

The PMNG 4–40 HE combines efficient membrane technology, compact installation, and simple operation for dependable on-site nitrogen generation.

 

Lower Air Consumption

Uses up to 35% less air on average, with savings of up to 51% compared with other membrane generators.

 

Compact Footprint

Provides increased nitrogen flow while maintaining a space-saving installation.

 

Instant Purity Selection

Allows users to select nitrogen purity between 95% and 99.5%.

 

Plug & Play Operation

Integrated filtration and components simplify installation without specialist commissioning.

 

No Buffer Vessels

The all-in-one design produces nitrogen without requiring additional process vessels.

 

Purelogic Touch Controller

Provides control, monitoring, and connectivity for easier system management.

Frequently Asked Questions

Find quick answers about the PMNG 4–40 HE membrane nitrogen generator, including purity, capacity, efficiency, operation, and installation.
The PMNG 4–40 HE provides nitrogen purity from 95% to 99.5%, allowing users to select the required purity according to their application.
It uses hollow polymer membrane technology to separate nitrogen from compressed air. Oxygen and other gases permeate through the membrane while nitrogen remains concentrated at the outlet.
The manufacturer states that the PMNG HE uses 35% less air on average, with savings of up to 51% compared with other membrane generators.
The PMNG 40 HE can deliver up to 246.9 Nm³/h at 95% purity, with delivery varying according to the selected nitrogen purity.
The specified inlet pressure range is 4–13 barg, with an ambient temperature range of 5–50°C.
No. Its plug-and-play, all-in-one design integrates filtration and key components, allowing straightforward installation without specialist commissioning.
