Analytical to Industrial-Grade Onsite Gas Production

Bring a critical resource in-house to ensure supply security, improve operational resilience, and reduce long-term costs.

EHL Group designs and delivers advanced onsite gas generation systems that provide a highly reliable alternative to traditional cylinder or bulk liquid gas supply. Using proven non-cryogenic technologies, our solutions allow organisations to produce Nitrogen, Oxygen, and Hydrogen directly at the point of use, eliminating the need for frequent deliveries, storage risks, and supply chain dependency.

Onsite gas generation ensures a continuous, scalable, and controllable supply of process gases, enabling facilities to match production output with operational demand. From analytical laboratory environments requiring ultra-high purity gases to large industrial installations needing high-volume flow rates, EHL systems are engineered to provide consistent performance, efficiency, and compliance with modern safety standards.

Our solutions are widely deployed across manufacturing, healthcare, water treatment, mining, defence, research laboratories, energy production, and environmental management, where reliable gas supply is essential to maintaining uninterrupted operations.

By bringing gas production onsite, organisations gain:

• Full supply independence and resilience against market fluctuations or delivery disruptions
• Reduced operating costs through elimination of cylinder rental, transport, and bulk gas contracts
• Improved safety by reducing the handling and storage of high-pressure cylinders or cryogenic liquids
• Lower carbon emissions due to reduced transportation and improved energy efficiency
• Scalable systems that can expand as operational demand grows

EHL provides complete engineering support, including system design, technology selection, installation, commissioning, and ongoing maintenance to ensure optimal performance throughout the lifecycle of the system.

Nitrogen Generation

High-Purity Nitrogen Production (95% – 99.9995%)

Nitrogen is one of the most widely used industrial gases, supporting applications across manufacturing, food preservation, electronics, pharmaceuticals, mining, and laboratory environments. EHL nitrogen generation systems provide secure, on-demand nitrogen production, ensuring facilities maintain continuous access to the purity levels required for critical processes.

Using advanced Pressure Swing Adsorption (PSA) or membrane separation technology, our systems separate nitrogen from compressed air, producing a stable supply with purity levels ranging from 95% to ultra-high purity of 99.9995% (5 ppm oxygen).

Producing nitrogen onsite eliminates the need for delivered gas cylinders or bulk liquid nitrogen tanks, significantly reducing logistics complexity while improving safety and operational efficiency.

Key Benefits

Operational Self-Sufficiency
Facilities gain complete independence from external gas suppliers by generating nitrogen internally, ensuring availability even in remote or high-demand environments.

Cost Reduction
Onsite generation removes ongoing expenses such as cylinder rental, delivery charges, bulk liquid storage, and gas loss through venting or evaporation.

Lower Environmental Impact
Eliminating regular gas deliveries significantly reduces transportation emissions while improving energy efficiency within the facility.

Improved Safety
Removing high-pressure cylinders and cryogenic liquid storage reduces handling risks and simplifies workplace safety management.

Scalable System Design
EHL nitrogen systems are engineered to grow with operational demand, allowing additional capacity to be integrated as production increases.

Nitrogen generators can be delivered as stand-alone units, skid-mounted packages, or fully integrated plant systems, tailored to meet specific purity, pressure, and flow requirements.

Oxygen Generation Systems

Reliable Onsite Oxygen Supply (92% – 99.5% Purity)

Oxygen plays a vital role across numerous industrial, environmental, and medical applications. EHL oxygen generation systems deliver continuous, high-purity oxygen production onsite, ensuring reliable availability while eliminating reliance on delivered gas supplies.

Using advanced adsorption technologies, oxygen generators extract oxygen from ambient air and deliver purity levels ranging from 92% to 99.5%, depending on the technology and system configuration.

Onsite oxygen generation is widely used in applications where consistent supply, operational reliability, and cost control are essential.

Common Applications

• Municipal and industrial water and wastewater treatment
• Hospitals and healthcare facilities
• Aquaculture and fish hatcheries
• Mining and mineral processing
• Environmental remediation and pollution control
• Ozone generation systems
• Military and remote operations
• Industrial combustion enhancement

EHL engineers oxygen systems to support both compact installations and large-scale industrial plants, providing flexible options to suit a wide range of operational environments.

Available System Configurations

Self-Contained Generators
Compact, integrated units designed for simple installation and dependable oxygen production within existing facilities.

Mini Pack Generators
Small footprint systems ideal for laboratories, pilot plants, research facilities, and low-volume industrial processes.

Standard Oxygen Generators
Robust modular systems capable of delivering consistent oxygen output across diverse industrial operations.

Packaged Oxygen Systems
Turnkey systems incorporating compressors, air preparation, storage vessels, and automated control systems to provide complete onsite oxygen production.

Cylinder Refilling Plants
Specialised systems that allow facilities to produce and fill oxygen cylinders onsite, supporting internal operations or distribution networks.

VPSA Plants (Vacuum Pressure Swing Adsorption)
Large-scale, energy-efficient oxygen plants capable of supplying high flow rates for major industrial operations, municipal infrastructure, and mining facilities.

By generating oxygen onsite, organisations gain greater control over supply reliability while significantly reducing operational costs associated with delivered gas systems.

Industrial Hydrogen Generation Systems

High-Purity Hydrogen Production Using Advanced Electrolysis

Hydrogen is increasingly important across industrial manufacturing, electronics production, energy research, and chemical processing. EHL hydrogen generation systems utilise advanced European electrolytic technology to produce hydrogen and oxygen directly from water using a highly efficient electrolysis process.

These systems generate two independent gas streams — hydrogen and oxygen — delivered at the required operating pressure, removing the need for external compression in many applications. Available output pressures include 5, 12, or 30 bar, allowing integration with a wide range of industrial processes.

Single generator units can produce:

• Hydrogen: up to 170.6 m³/hr at 99.5% purity
• Oxygen: up to 85.3 m³/hr at 99% purity

For applications requiring extremely high purity, EHL provides advanced purification technologies capable of achieving hydrogen purity levels up to 99.9995%. These purification systems can be supplied either as stand-alone modules or integrated directly into the generator package.

Typical Hydrogen Applications

• Semiconductor and electronics manufacturing
• Laboratory and analytical instrumentation
• Metallurgical processing
• Chemical production
• Energy and fuel cell development
• Heat treatment processes
• Emerging hydrogen energy infrastructure

Producing hydrogen onsite eliminates the challenges associated with transporting and storing compressed hydrogen cylinders while providing greater control, safety, and operational efficiency.
