On‑Site Nitrogen Generation Systems for Australia, New Zealand and the Pacific
EHL End‑to‑End Design, Installation and Lifecycle Support
Delivering Supply Certainty, Cost Control and Operational Resilience Across ANZ & the Pacific
Across Australia, New Zealand and the Pacific Islands, nitrogen is a critical utility supporting manufacturing, resources, healthcare, infrastructure and utilities—often in remote, regional, or logistics‑constrained environments.
Reliance on bulk liquid or cylinder nitrogen introduces supply risk, escalating costs, and operational vulnerability. On‑site nitrogen generation systems provide a proven alternative by delivering secure, continuous supply with predictable operating costs and no reliance on external gas providers.
EHL has extensive experience delivering fully engineered on‑site nitrogen generation solutions throughout Australia, New Zealand and Pacific locations, supporting clients across regulated, safety‑critical and continuous‑process environments.
End‑to‑End On‑Site Nitrogen Generation Capability
EHL designs and delivers whole‑of‑system nitrogen generation solutions, engineered to operate as compliant, reliable plant utilities rather than standalone equipment.
EHL Scope of Supply and Services
- Nitrogen demand analysis and load profiling
- Specification of purity, flow, pressure and redundancy
- Technology selection: PSA or membrane
- Mechanical, electrical and control system design
- Integration with compressed air and plant services
- Indoor and outdoor system deployment
- Commissioning, validation and handover
- Ongoing maintenance, service and optimisation
All systems are engineered to align with relevant Australian Standards (AS), New Zealand Standards (NZS) and applicable plant, electrical, safety and pressure equipment requirements.
PSA and Membrane Nitrogen Generation Technologies
EHL delivers both Pressure Swing Adsorption (PSA) and membrane nitrogen generation systems, allowing optimal alignment with purity requirements, site conditions, and lifecycle cost expectations.
Pressure Swing Adsorption (PSA) Nitrogen Systems
PSA technology is selected for high‑purity and quality‑critical applications, particularly common in regulated Australian and New Zealand industries.
Typical characteristics
- Nitrogen purity up to 99.999%
- Medium to high flow rates
- High process repeatability
- Suitable for continuous and batch operations
Common applications
- Food and beverage packaging (modified atmosphere packaging)
- Pharmaceuticals and laboratories
- Electronics and precision manufacturing
- Heat treatment and metallurgical processes
PSA systems are engineered to support compliance with:
- AS/NZS 4024 – Safety of machinery
- AS 1210 / AS 4343 – Pressure equipment
- AS/NZS 3000 – Electrical installations
- Site‑specific food, healthcare or quality standards where applicable
Membrane Nitrogen Generation Systems
Membrane nitrogen systems provide a robust, low‑complexity solution, particularly well‑suited to remote Australian sites and Pacific Island installations.
Typical characteristics
- Continuous nitrogen production
- Lower mechanical complexity
- Reduced maintenance requirements
- Strong suitability for harsh or outdoor environments
Common applications
- Mining and mineral processing
- Oil and gas facilities
- Fire prevention and inerting
- Utilities, infrastructure and remote installations
Membrane systems are commonly selected where reliability, simplicity and minimal intervention are prioritised over ultra‑high purity.
Modular and Large‑Scale Industrial Nitrogen Systems
EHL delivers nitrogen generation systems ranging from modular and skid‑mounted units to large industrial nitrogen plants supporting multi‑user distribution networks.
Deployment Options
- Modular PSA or membrane skids
- Containerised outdoor systems
- Central nitrogen plants with redundancy
- Duty/standby and N+1 configurations
Systems are engineered for:
- Indoor plant rooms
- Outdoor Australian climate conditions
- Coastal and tropical Pacific environments
- Greenfield and brownfield facilities
All installations consider:
- Electrical zoning and hazardous area interfaces
- Pressure equipment compliance
- Safe access and maintainability
- Integration with site safety management systems

24/7 Supply Certainty with No Reliance on External Gas Providers
Logistics challenges across Australia, New Zealand and the Pacific can significantly impact delivered gas supply.
Risks Associated with Delivered Nitrogen
- Long lead times and delivery delays
- Road, port or shipping disruptions
- Supplier shortages and allocation constraints
- Escalating rental, freight and demurrage costs
- Safety risks from cylinder handling
Benefits of On‑Site Nitrogen Generation
- Continuous 24/7 nitrogen availability
- No reliance on external suppliers or delivery schedules
- Nitrogen produced on demand, on site
- Removal of logistics and transport risk
On‑site nitrogen generation transforms nitrogen into a controlled, self‑managed utility, improving supply security and operational confidence.
Cost Reduction and Predictable Lifecycle Economics
For procurement managers, asset owners and finance teams, on‑site nitrogen systems deliver strong lifecycle value.
Financial and Commercial Benefits
- Elimination of cylinder rental and handling costs
- Removal of freight, shipping and demurrage exposure
- Stable operating costs driven primarily by electricity
- Lower cost per Nm³ over system life
- Reduced supplier, contract and administrative complexity
EHL designs systems to deliver clear payback periods and predictable total cost of ownership, particularly advantageous in remote and high‑logistics‑cost regions.
Operational Resilience for Plant Managers and Operators
Plant and operations managers require nitrogen supply that does not compromise production or safety.
EHL engineers operational resilience through:
- Redundant generation capacity
- Intelligent control and alarm systems
- Duty/standby configurations
- Predictive and preventative maintenance strategies
- Local ANZ‑based technical support
This approach ensures nitrogen availability during maintenance, peak demand and unexpected operating events.
Lifecycle Maintenance, Compliance and Local Support
EHL provides ongoing lifecycle support across Australia, New Zealand and Pacific projects, including:
- Planned maintenance programs
- Performance audits and optimisation
- Spare parts and consumables management
- Capacity expansion and system upgrades
- Operator training, documentation and compliance support
This lifecycle focus ensures long‑term safety, availability and regulatory alignment.
