Measurement technology for industrial gases
Industrial gases are essential “building blocks” of numerous industrial, commercial and technical processes.
They are used in many forms – as pure gases, in liquid or cryogenic form, as gas mixtures or as compressed gases.
Whether for welding and cutting processes, protective atmospheres, cooling, food packaging, chemical processes or cryogenics:
the right gas selection is crucial for efficiency, safety and product quality.
Several factors are important when selecting and using industrial gases:
• The chemical or physical properties of the gas (e.g. reactive, inert, cryogenic)
• The intended purpose (welding, cooling, inerting, storage, etc.)
• Requirements regarding purity, pressure, handling and safety
• Cost-effectiveness, availability and delivery form (cylinder, liquid gas, on-site generation)
Overview: gases, properties and typical applications
| Gas / gas mixture | Main applications | Typical properties / advantages |
|---|---|---|
| Oxygen (O₂) | Welding, cutting, combustion processes, chemical processes, water treatment | Reactive, oxidising, promotes combustion / process reactions |
| Nitrogen (N₂) | Inerting, protective atmospheres, food packaging, compressed air, cryogenics | Inert, non-flammable, displaces oxygen, versatile |
| Argon (Ar) | Welding (TIG/MIG), metal processing, semiconductor production, shielding atmospheres | Noble gas, inert, non-reactive, prevents oxidation and contamination |
| Carbon dioxide (CO₂) | Food & beverage industry (carbonation, packaging), fire extinguishing systems, welding, process gas | Economically available, versatile, partly inert |
| Hydrogen (H₂) | Chemical / petrochemical industry, fuel cells, heat treatment, special processes | Very light, high energy/thermal properties, highly versatile |
| Helium (He) | Cryogenics, leak detection, shielding gas applications, electronics, research | Inert, very low density, high thermal conductivity, non-flammable |
| Acetylene (C₂H₂) / fuel gases | Oxy-fuel welding and cutting, very high flame temperatures | High flame temperature, efficient & flexible for metalworking processes |
Depending on the industry and application, requirements vary greatly – from high purity and compressed gas storage
to cryogenic temperatures or gas mixtures.
Industrial gases enable significant increases in efficiency, quality improvements and process safety in many applications.
At the same time, safe handling, storage and process control are essential for their proper use.
Applications
Cryogenic tanks
Cryogenic tanks are used for the safe storage and supply of deeply refrigerated liquefied gases such as
nitrogen (–196 °C), oxygen (–183 °C), argon (–186 °C), carbon dioxide or helium (–269 °C).
They are a central element in the supply of industrial gases and are used across many industries –
from laboratories, medical technology and the food industry to chemicals, metal processing and cryogenics.
With their special double-wall or vacuum insulation, cryogenic tanks minimise heat ingress and ensure
stable temperatures over long periods. Precise control and monitoring systems ensure that
pressure, fill level and temperature always remain within safe limits. Modern tanks also offer
digital interfaces to monitor operating conditions in real time and automate processes.
Typical requirements for cryogenic tanks
- Excellent thermal insulation to minimise boil-off losses
- High operational safety through pressure regulation and multi-level safety valve systems
- Suitable for a wide range of storage capacities – from laboratory vessels to large storage tanks
- Compatibility with stationary installations and distribution systems
- Robust construction for continuous industrial use
- Possibility of automated monitoring and remote maintenance
Depending on the gas type and technical requirements, different tank designs are used.
The following table provides an overview of typical cryogenic tank types.
Overview of typical cryogenic tank types
| Tank type | Application | Capacity / size | Special characteristics |
|---|---|---|---|
| Stationary vacuum-insulated tanks | Industry, medical sector, laboratories, gas supply centres | 500–100,000 litres | Very low boil-off rate, durable construction, ideal for central gas supply |
| Cryogenic transport tanks | Transport and distribution of liquefied gases | 1,000–30,000 litres | Mobile, robust vehicle units; shock- and vibration-resistant |
| Dewar vessels | Laboratory, research, medical applications | 1–100 litres | Easy handling, lightweight, ideal for frequent withdrawals |
| High-pressure cryogenic tanks | Industrial processes with elevated operating pressure | 500–20,000 litres | Combination of low temperature and increased operating pressure |
| MicroBulk tanks | Small businesses, laboratories, clinics | 230–1,500 litres | Replacement for cylinder bundles, low boil-off losses, automated filling |
The choice of a suitable cryogenic tank depends heavily on the type of gas, consumption profile,
supply chain and safety requirements. Modern tanks ensure a reliable supply even in demanding
environments and contribute significantly to process safety and efficiency.
With increasing digitalisation, cryogenic tanks are often integrated into higher-level monitoring
and control systems to automatically record fill levels, pressure conditions and operating data.
This improves planning reliability, reduces energy losses and enables cost-efficient operation.

Valves with integrated pressure regulators
Valves with integrated pressure regulators are essential components in gas supply and industrial systems
where a constant and safe working pressure must be ensured. They combine the function of a shut-off valve
with a precise pressure regulator in a single component – a space-saving, reliable and highly economical
solution for numerous applications in gas supply, welding technology, laboratory automation,
process engineering and cryogenics.
Thanks to their integrated control mechanism, these valves maintain the downstream working pressure
constant regardless of fluctuations in inlet pressure. This protects downstream equipment, improves
process stability and enables uniform gas withdrawal. At the same time, they reduce installation effort,
potential leak points and downtime during operation. Depending on the design, modern valves offer adjustable
or fixed pressure ranges as well as safety functions such as overpressure protection or backflow prevention.
Typical advantages of integrated pressure-regulating valves
- Combination of shut-off and pressure regulation in a single component
- Constant and stable gas supply even with fluctuating inlet pressures
- Reduced installation and service costs
- Fewer connection points → lower risk of leakage
- Long service life thanks to robust design and precise spring/membrane technology
- Ideal for laboratory, industrial and high-safety applications
The following table provides a structured overview of common valve types with integrated pressure regulation

Hydrogen (H₂)
Hydrogen is one of the most versatile industrial gases and is becoming increasingly important
in the context of the energy transition. Whether as a process gas in the chemical industry,
as a shielding gas in metallurgy or as an energy carrier for fuel cells – H₂ is used in numerous
industrial and technological applications. Thanks to its high mass-specific energy density and
reactive properties, hydrogen enables efficient processes and sustainable applications in industry,
mobility and energy systems.
Depending on the production method, a distinction is made between grey, blue, turquoise and green hydrogen.
Green hydrogen – produced from renewable energies via electrolysis – plays a key role in climate-neutral
industrial and energy systems. Nevertheless, due to its properties, H₂ places special demands on storage,
transport and safety technology: Its small molecular size, high diffusion rate and wide ignition range
require high-quality materials, reliable fittings and state-of-the-art monitoring technology.
Typical advantages and properties of hydrogen
- Very high specific energy per unit mass
- Fuel-cell capable with zero direct emissions
- Lightest of all gases → rapid dispersion in ambient air
- Reactive → ideal for chemical and metallurgical processes
- Can be produced renewably (green hydrogen)
- Usable as energy storage and process gas
The following table provides a structured overview of the different types of hydrogen,
their applications and specific requirements.
Hydrogen types and typical application areas
| Hydrogen type | Production / origin | Typical applications | Special requirements |
|---|---|---|---|
| Green hydrogen | Electrolysis using renewable energy | Fuel cells, industrial processes, energy storage | High purity, advanced electrolysis systems |
| Blue hydrogen | Steam reforming with CO₂ capture | Chemicals, refineries, thermal processes | CO₂ sequestration, large production facilities |
| Grey hydrogen | Steam reforming from natural gas | Metallurgy, ammonia synthesis, process industry | No CO₂ capture, established production chain |
| Turquoise hydrogen | Methane pyrolysis | Industrial processes, energy systems | Solid carbon separation, evolving technology |
| Cryogenic hydrogen (LH₂) | Liquefaction at –253 °C | Aerospace, mobility, energy storage | Special cryogenic tanks, boil-off losses, strict safety requirements |
| Compressed hydrogen (CGH₂) | High-pressure storage (e.g. 200–700 bar) | Mobility, industry, laboratories | High-pressure systems, tight fittings, leak monitoring |
Safe handling of hydrogen requires high-quality materials, precise control technology and
reliable sensor systems. Fittings, pipelines and valves must be diffusion- and hydrogen-resistant,
while monitoring systems must detect and report leaks early and reliably. Today, mature solutions
are available for industrial and energy applications – from high-pressure storage systems
and switchover units to complex hydrogen distribution systems.
Hydrogen is a key component of modern industrial and energy systems and will play an even greater role
in decarbonisation, mobility and sustainable production chains in the future.

LPG, LNG and CNG accessories
For the safe, efficient and standard-compliant operation of LPG (liquefied petroleum gas),
LNG (liquefied natural gas) and CNG (compressed natural gas) systems, high-quality accessories
are essential. These energy carriers are used in industry, transportation, heating systems
and increasingly in alternative mobility solutions. Each system places different demands on
pressure regulation, material resistance, temperature behaviour and safety mechanisms.
Accessories for LPG, LNG and CNG must be robust, temperature-resistant and tailored to the
respective energy form. While LPG is stored in liquid form at moderate pressures, CNG requires
high-pressure-resistant systems, and LNG must be handled under cryogenic conditions. Accordingly,
fittings, valves, hoses and regulators are specially designed to ensure durability and safety
in everyday operation.
Typical requirements for LPG, LNG and CNG accessories
- High material resistance to low temperatures and high pressures
- Explosion-proof and safety-compliant designs (ATEX, PED, ISO)
- Pressure regulation and gas handling adapted to the storage form
- Secure connection technology with minimal leakage risk
- Compatibility with mobile and stationary systems
- High durability and robust construction for industrial use
The following table provides a structured overview of common accessories for LPG, LNG and CNG
applications and their special features.

Gas extinguishing systems
Gas extinguishing systems protect rooms, technical installations and sensitive infrastructure from fire
without using water or foam. They are used wherever conventional extinguishing methods would cause damage –
for example in data centres, archives, switchgear rooms, medical facilities or industrial production areas.
By using special extinguishing gases, oxygen is displaced, chemical combustion reactions are interrupted
or heat is removed, allowing the fire to be extinguished quickly and without residue.
These systems operate extremely quickly, often in less than 10 seconds, providing a decisive advantage
over mechanical extinguishing methods. At the same time, they require maximum reliability,
precise system design and safe storage of extinguishing agents. Modern gas extinguishing systems are integrated
into building management systems, feature pressure relief ventilation and include redundant safety devices.
Typical requirements for gas extinguishing systems
- Residue-free fire suppression without damaging sensitive equipment
- Rapid activation and uniform flooding of the protected area
- Extinguishing agents compliant with standards such as EN 15004 or ISO 14520
- Automatic detection and activation through fire alarm systems
- High safety for personnel, including escape routes and acoustic pre-alarms
- Regular leak and functional testing
The table below provides a compact overview of common extinguishing systems and their characteristics.
Overview of typical gas extinguishing systems
| System type | Extinguishing agent | Application area | Special features |
|---|---|---|---|
| Inert gas extinguishing systems | IG-55, IG-541, IG-100, argon, nitrogen | Data centres, archives, industrial facilities | Displaces oxygen, residue-free, high personnel safety |
| Chemical extinguishing systems (FK-5-1-12) | Novec™ 1230 / FK-5-1-12 | IT, medical technology, power distribution | Fast action through heat absorption, very low environmental impact |
| CO₂ extinguishing systems | Carbon dioxide | Industrial processes, machine rooms, enclosed systems | Very effective, but suitable only for unoccupied areas |
| High-pressure inert gas systems | Ar, N₂ or gas mixtures | Large-scale systems, industrial halls | High discharge pressure, suitable for large room volumes |
| Cryogenic extinguishing systems | Liquid inert gases | Laboratories, special applications | Rapid vaporisation, ideal for compact spaces |
Gas extinguishing systems are an integral part of modern fire protection concepts – especially
in environments where downtime, material damage or data loss would have significant economic consequences.
They combine rapid fire suppression with high efficiency and leave no residues that could damage equipment
or sensitive assets.
Thanks to intelligent detection systems, digital monitoring and precise pressure control,
modern gas extinguishing systems provide maximum safety and can be tailored precisely to the spatial and
technical requirements of each protected area.
