About Air Products
Air Products is a company for industrial gas production and gas technology founded in 1940, headquartered in Allentown, Pennsylvania (USA). The company produces and supplies gases such as nitrogen, oxygen, argon, helium, hydrogen and carbon dioxide in liquid and gaseous form, and plans, builds, owns and operates plants such as Air Separation Units, hydrogen PSA systems and pipeline networks. In addition, Air Products offers plant engineering and operation (Cold Box design and repair, O&M packages), turboexpanders through its subsidiary Rotoflow, cryogenic freezing and cooling technology (Freshline, PolarFit), Smart Technology monitoring, as well as process audits, CFD modeling and operator training. With more than 18,000 employees, more than 750 production plants, approximately 1,800 miles of industrial gas pipeline and revenue of USD 12 billion (FY25), the company serves over 50 countries and industries such as semiconductors/electronics, metals/materials processing, food, chemicals/refining, energy/LNG, biotechnology/pharma, medical, glass and foundries. Its core competence is on-site gas production, the company's original founding concept.
