- ErreDue S.p.A. is an Italy-based engineering and manufacturing company specializing in the design, production, and distribution of on-site generation, purification, and mixing systems for technical and medical gases. Founded in 2000 and headquartered in Livorno, Italy, the company is listed on the Euronext Growth Milan market (MIL: RDUE). ErreDue serves industrial, laboratory, medical, and energy transition sectors across Italy, the European Union, and international markets.
The company's core product offerings include electrolytic hydrogen generators utilizing Proton Exchange Membrane (PEM) and alkaline technologies under the Sirio, Mercury, Saturn, and Piel brand names; pressure swing adsorption (PSA) molecular sieve nitrogen generators sold under the NitroBOX, Venus, Galileo, and Mars brands; medical- and industrial-grade oxygen generators under the Oxylife and Orion lines; zero air, pure air, and carbon dioxide generation systems; industrial gas mixers and purifiers; specialized stainless steel systems under the GN Inox brand; and high-pressure gas booster compressors. In addition to equipment manufacturing, ErreDue delivers end-to-end lifecycle services, including long-term and short-term equipment rental programs; turnkey plant engineering, customized design, and installation; scheduled preventive maintenance and technical assistance; remote diagnostic monitoring; and the supply of spare parts and consumables. Its systems support critical applications across metal fabrication, laser cutting, metallurgical heat treatment, sintering, electronics manufacturing, analytical laboratories, pharmaceutical production, food packaging under modified atmosphere, winemaking, and hospital gas networks.
In recent corporate developments, ErreDue completed the strategic acquisition of the historic Piel brand from McPhy Energy in July 2026, strengthening its global market presence in hydrogen generation equipment. To accommodate expanding production demands for the energy transition, the company finalized the construction and commissioning of its new 16,000-square-meter Gigafactory headquarters and manufacturing facility in Livorno, specifically scaling up production lines for large-capacity electrolyzers. Furthermore, ErreDue formalized a 36-month extension of its technological collaboration agreement with the Italian National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA) to co-develop advanced hydrogen production technologies, while securing multi-unit supply contracts for megawatt-class PEM electrolyzers deployed in regional Hydrogen Valley decarbonization initiatives under Italy's National Recovery and Resilience Plan (PNRR).
