SIAD Macchine Impianti S.p.A. is the engineering arm of the SIAD Group, an Italian chemical conglomerate headquartered in Bergamo. Established in 1953 as a spin-off from the parent SIAD S.p.A. (founded 1927 by the Sestini family), it leads the group's engineering division and focuses on the design, manufacture, and global installation of industrial plants and equipment.
Core products include reciprocating compressors for process gases and air (API 618 compliant and oil-free models for hydrogen and other applications), air separation units (ASUs) for high-purity industrial gases, natural gas liquefaction (LNG) plants, CO2 capture and liquefaction systems, biogas upgrading and biomethane liquefaction facilities, and combustion systems. These serve sectors such as refining, petrochemicals, chemicals, energy, metallurgy, and food processing.
The company maintains a worldwide presence through subsidiaries, offices, and service centers in Europe, the Americas (including SIAD Americas LLC), China, India, Russia, the UAE, and elsewhere. It has delivered over 500 ASUs and LNG plants plus thousands of compressors to international clients. As a family-owned entity within the SIAD Group (turnover exceeding €1 billion, ~2,400 employees), it emphasizes innovation in decarbonization, hydrogen technologies, and sustainability, recently supplying hydrogen compressor systems for projects like e-methane plants.
SIAD Macchine Impianti positions itself as a global leader in cryogenic and compression solutions, supported by in-house R&D, a global service division, and recent investments in expanded manufacturing capacity in Italy.
Also known as SIAD MI and SIAD Group Engineering.
