Custom-engineered membrane nitrogen solutions — not standard products
BERG does not offer one fixed membrane nitrogen generator for every application. Each system is designed according to the required nitrogen flow, purity, pressure, operating conditions and installation concept.
Our engineers evaluate the complete process, including the available compressed air, required air quality, ambient temperature, operating environment, controls, monitoring and connection to the customer’s process.
This creates a complete industrial membrane nitrogen generator system rather than a collection of individual components.
Containerized systems
Protected and pre-integrated solutions for outdoor, remote and international project locations.
German manufacturing
Mechanical assembly, piping, electrical integration and final system testing are carried out in Germany.
Complete integration
Compressor, dryer, filters, membrane modules, controls and nitrogen receiver can be integrated into one solution.
Technology advantages
Why choose membrane nitrogen generation?
Membrane nitrogen generation is suitable for many continuous industrial applications within the 95% to 99.7% nitrogen purity range, particularly where compactness, modularity and straightforward operation are important.
Continuous on-site supply
Generate nitrogen from compressed air directly at the point of use.
Compact modular design
Membrane module racks can be configured for different project capacities.
Project-specific purity
Designed for nitrogen purity requirements from 95% up to 99.7%.
Simple operating concept
Continuous membrane separation supports a straightforward process.
Remote-site suitability
Suitable for containerized, outdoor and remote industrial installations.
Flexible capacity design
Module quantity, controls and air treatment are selected for each project.
Reduced delivery logistics
On-site nitrogen generation can reduce dependence on external gas deliveries.
Industrial integration
Integrates with an existing air network or a complete new compressor system.
Complete process engineering
A complete nitrogen system starts before the membrane
Membrane performance depends strongly on compressed air preparation. The membrane module is only one part of a complete and reliable industrial nitrogen generation solution.

Correct compressed air preparation
Protecting the membrane starts with air quality
The compressed air supply must be correctly filtered and dried before entering the membrane modules. Particles, oil aerosols and unsuitable moisture conditions may negatively affect system reliability and membrane lifetime.
BERG designs the pressure dew point safely below the membrane feed temperature and selects the filtration stages according to the compressor, ambient conditions and membrane requirements.

Installation concepts
Skid-mounted or containerized nitrogen systems
The system architecture is selected according to the installation site, available infrastructure, ambient conditions and required level of pre-assembly.
Membrane separation quality
High-quality membrane technology integrated into a BERG system
BERG combines proven membrane technology with German system engineering, mechanical assembly, electrical integration and final testing.
Compressed air enters bundles of polyimide hollow fibres. Oxygen, water vapour and other fast-permeating components pass more rapidly through the membrane wall, while a nitrogen-enriched gas stream continues to the product outlet.
✓ Polyimide hollow fibre technology
✓ High selectivity and permeability
✓ Stable project-specific operation
✓ Compact skid and container integration

Safety note: Safety-related applications, including fire prevention, inerting and explosion-risk reduction, require project-specific evaluation, process risk assessment and compliance with all applicable regulations.
Technology selection
Membrane or PSA nitrogen generator—which technology fits your project?
BERG offers both technologies and selects the correct solution according to purity, flow, compressed air availability, energy priorities and installation conditions.
| Requirement | Membrane N₂ system | PSA N₂ system |
|---|---|---|
| Typical purity | 95% to 99.7% for this BERG system range | Often selected for very high nitrogen purities |
| Process | Continuous membrane separation | Cyclic adsorption process |
| Footprint | Compact and modular | Depends on capacity, purity and vessel arrangement |
| Containerization | Very suitable for compact and remote systems | Also possible as a containerized PSA solution |
| BERG approach | Custom-engineered | Custom-engineered |
BERG does not present one technology as universally superior. Visit our industrial nitrogen generator overview for further system information.
