Hydrogen
Hydrogen for zero-emission mobility
High-purity hydrogen compliant with ISO 14687:2025 for fuel cells, produced through Steam Methane Reforming with Carbon Capture and CO2 recovery, and cryogenically purified.
Internal Group supply chain and widespread distribution through cylinders, cylinder bundles and tube trailers.
Gases, technologies and services for automotive
SIAD supports the automotive industry throughout the entire production cycle, from welding and cutting components to emission testing, including additive manufacturing and hydrogen for mobility.
For every need, there is a complete range of gases, certified mixtures and services, with flexible supply and technical support.
Welding PRO: mixtures for welding and cutting
Welding PRO is the line designed for high-productivity industrial welding. ARGOPRO works well on carbon and stainless steels, HELIPRO brings helium where performance is needed on aluminium and thick steels, while HYDRAPRO uses hydrogen on stainless steels and for root protection. For galvanized steels, HELIPRO GV is the choice, helping to reduce spatter and fumes.
Gases and mixtures for emission testing
For emission analyses on test benches, SIAD supplies pure gases and calibration mixtures compliant with GTR 15-WLTP and UN ECE R49. These are certified and fully traceable mixtures, accompanied by a Certificate of Analysis showing the dual vol/mol unit of measurement, to meet different international regulations.
SIAD Hydrogen
SIAD high-purity hydrogen is compliant with ISO 14687:2025 for fuel cell applications. It is obtained through Steam Methane Reforming with Carbon Capture and cryogenically purified. Availability is guaranteed through cylinders, cylinder bundles and tube trailers.
Additive, services and technologies
For additive manufacturing of structural and powertrain components made of aluminium alloys, Inconel, titanium or stainless steel, SIAD supplies high-purity argon and nitrogen.
