Dry nitrogen generator

high-purityhigh-concentrationindustrial

Overview
Custom-engineered, skid-mounted or containerized membrane nitrogen generator systems for continuous on-site nitrogen production. Systems are manufactured and assembled in Germany and designed for industrial applications where nitrogen purity between 95% and 99.7% N2 is required. Complete solutions include compressed air treatment, membrane separation modules, controls, safety components and turnkey integration.

Key features

• Designed and assembled in Germany
• Nitrogen purity: 95% – 99.7% N2
• Skid-mounted or containerized project systems
• Custom engineering for flow, purity, pressure and installation concept
• Continuous on-site supply to reduce dependence on delivered gases
• Compact, modular design suitable for remote and outdoor installations
• PLC control and remote monitoring options

System components / Process components

• Compressor and compressed air receiver
• Multi-stage filtration (particle and oil removal)
• Dewpoint-controlled dryer sized for membrane feed
• Fine filtration ahead of membrane modules
• Polyimide hollow-fibre membrane modules
• Nitrogen receiver and pressure regulation
• Oxygen, flow and pressure monitoring instruments
• PLC controls and electrical integration

Technology advantages

• Continuous membrane separation: steady on-site nitrogen supply
• Modular membrane racks: scalable capacity by adding modules
• Project-specific purity from 95% to 99.7% depending on configuration
• Simplified operation compared with cyclic adsorption systems
• Suitable for containerized, remote or outdoor installations
• Flexible capacity and control design tailored per project
• Reduces logistics and reliance on delivered gas cylinders or bulk supply
• Integration capability with existing compressed air networks or complete compressor packages

Installation concepts

• Skid-mounted systems: compact turnkey units for compressor rooms and indoor technical areas
• Containerized systems: pre-integrated, weather-protected solutions for outdoor and remote sites (options: insulation, ventilation, heating/cooling, electrical cabinet)

Membrane separation quality
Polyimide hollow-fibre membranes selectively allow oxygen, water vapour and other fast-permeating components to pass through the membrane wall while producing an N2-enriched product stream. Correct compressed air preparation (filtration, drying and dewpoint control) is essential to maintain membrane performance and lifetime.

Industrial applications

• Mining and tunnelling (containerized supply for remote projects)
• Oil & gas (purging, blanketing and utility duties)
• Marine and shipyards
• Food storage and packaging
• Beverage bottling
• Fire prevention and inerting (requires project-specific risk assessment)
• Tank blanketing and pipeline purging
• Chemical industry and general industrial N2 supply

Comparison: Membrane N2 system vs PSA N2 system
Requirement | Membrane N2 system | PSA N2 system
Typical purity | 95% – 99.7% for this membrane range | Often selected for very high nitrogen purities (>99.9%)
Process | Continuous membrane separation | Cyclic adsorption (PSA) process
Footprint | Compact and modular | Varies with capacity, purity and vessel arrangement
Containerization | Well suited to compact and remote systems | Also possible as containerized PSA solutions
Approach | Project-engineered systems | Project-engineered systems

Safety note
Applications related to safety (fire prevention, inerting, explosion-risk reduction) require project-specific evaluation, process risk assessment and compliance with applicable regulations and standards.
