The BOC Group

What The BOC Group does

The BOC Group is a Sydney-headquartered industrial gases and engineering company operating across Australia and New Zealand as a wholly-owned subsidiary of Linde plc (NYSE: LIN). The company produces and distributes industrial gases — oxygen, nitrogen, argon, carbon dioxide, helium, hydrogen, acetylene, and LPG — alongside medical gases and healthcare equipment, specialty gas mixtures, welding equipment and consumables, and emerging energy solutions including LNG and hydrogen. BOC serves six primary customer segments: healthcare and homecare, manufacturing and industrial, food and beverage, welding and fabrication, energy and transport, and agriculture and aquaculture. The business carries 130+ years of operating heritage in the region and is positioned as the South Pacific's leading gas and welding equipment specialist.

BOC's underlying technology centres on cryogenic air separation units (ASUs) producing oxygen, nitrogen, and argon, supplemented by LNG liquefaction and specialty gas formulation. Production and distribution infrastructure includes the $200M+ Chinchilla micro-LNG plant (Queensland, 50 tonnes/day output), the Longford CO2 processing facility (the South Pacific's largest merchant CO2 plant, opened December 2024), the Dandenong ASU and LNG facilities ($65 million upgrade), the Westbury micro-LNG plant in Tasmania (commissioned 2011), and a new multimillion-dollar ASU in Christchurch announced May 2026. BOC holds proprietary product brands and patented methods including GENIE lightweight aluminium cylinders (30% lighter than steel, 39% more nitrogen capacity), F3VIPR cylinders with integrated pressure regulators, MAPAX modified atmosphere packaging and leak detection, VAPORMATE and EDN FUMIGAS fumigants, CRYOLINE CS cryogenic spiral freezers, SOLVOX aquaculture oxygenation, and patented LNG refuelling technology.

The business operates an integrated multi-channel go-to-market model: direct field sales with dedicated enterprise account managers under long-term supply agreements (e.g., 10-year Viridian Glass deal, 15-year QGC agreement); Gas & Gear retail stores across Australia and New Zealand for SMB and walk-in customers; a comprehensive e-commerce platform serving 20,000+ online customers; a scan-to-reorder mobile application; a gas agent network for regional areas; and equipment reseller partners. Revenue streams include recurring industrial and medical gas supply contracts, cylinder rental income, welding equipment sales, and transactional LNG/hydrogen refuelling. Pricing is contract-based with subscription-style offerings including the FlexiGas Plan, TradeMate programme, and Fill for Less plans. Customer co-development is supported through an Application Technology Centre opened in South-West Sydney in 2022.
