What Siad Srl does
SIAD Group is an Italian, family-owned (Sestini family) industrial conglomerate founded in 1927 in Bergamo, operating across four divisions: industrial gases, engineering (via subsidiary SIAD Macchine Impianti), healthcare medical gases, and LPG/natural gas energy. The Industrial Gases division produces and distributes industrial, food-grade, specialty, medicinal, and refrigerant gases to sectors including food, automotive, chemicals, metallurgy, glass, cement, rubber, and research laboratories, reaching purity levels of 99.9999% (Grade 6.0). The Engineering division designs and builds Air Separation Units (600+ plants supplied worldwide), CO2 capture and liquefaction plants (300+ supplied), LNG and biomethane liquefaction plants, and reciprocating compressors (5,000+ supplied, including 550 bar oil-free hydrogen compressors). The Healthcare division supplies medical oxygen, respiratory circuits, and specialty medicinal gases to hospitals. The LPG and Natural Gas division, operated partly through Istrabenz Plini Group, supplies LPG, natural gas, and biomethane for industry, mobility, and heating across Slovenia, Croatia, and Serbia.
The company's business model combines recurring industrial and medical gas supply contracts with one-time engineered equipment sales, distributed through 300+ agencies and dealers across 16 European countries and a direct global engineering sales force (75 engineering agencies, 40 service sites, 6 production plants, plus SIAD Americas in Texas and SIAD Engineering in Hangzhou, China). Pricing is quote-based with multi-year B2B contracts. Geographically, SIAD is active in Italy, Croatia, Germany, Slovakia, Serbia, Slovenia, the United States, Canada, and the Middle East. The group reported $1.1 billion in annual revenue and 2,355 employees as of 2024. Recent strategic emphasis is on the energy transition, with significant capital deployment into hydrogen (compressors, Power-to-Methane, electrolyzer compression), biomethane/bio-LNG (Snam framework agreement, bioplus LNG plant), CO2 capture and utilization (Enviral, Solvay, Tenaris projects), and renewable energy supply for own operations (PPAs with A2A, Edison, EDP) targeting 25% emissions reduction and 40% renewable energy by 2026. The Group is led by Bernardo Sestini (Chairman and CEO) following the January 2024 passing of his father Roberto Sestini, who had led the company for over 50 years.
