Overview
Woikoski is a Finnish industrial company whose business developed from a carbon-black factory founded in 1882 into the production, processing, distribution, and handling of industrial and medical gases. The company is described as Finland’s oldest industrial and medical-gas supplier. Its historical development reflects the transition from chemical manufacturing based on carbon materials to gas production and related engineering services. The company’s early industrial activity centered on carbon black, also known as lampblack, a pigment used in industrial applications. Over time, Woikoski moved toward gas manufacture. Hydrogen production became an important stage in that transition, with oxygen generated as a by-product and sold for welding applications. This created a foundation for a broader gas business serving industrial customers and other professional users. The Woikoski name is associated with the Voikoski rapids and the industrial site developed there. Alfred A. Palmberg acquired a mill on the rapids in 1909 and established a millstone factory. The area was later transferred to his brother Bertil Palmberg, who established a chemical factory and power plant; both began operating in 1920. The gas works continued under Oy Woikoski Ab, incorporated in 1929. The company subsequently expanded beyond gas manufacture into the design and construction of systems for gas handling, storage, distribution, and use. Woikoski’s portfolio includes technical gases and medicinal gases, together with equipment and systems used to manage and distribute gases. It also imports welding and gas equipment and distributes these products with its own gases through a Finnish reseller network. Reference material describes a network of more than 200 agents in Finland and 13 plants and offices, although the relevant figures are associated with the period covered by the source and may not describe the company’s current footprint. The company has also operated in helium and carbon-dioxide processing. It exports liquid and gaseous helium and has an automated helium facility capable of recycling gaseous helium. In 2006, it completed a carbon-dioxide treatment plant designed to recover and recycle approximately one to three tonnes of carbon dioxide per hour. These activities indicate a business model extending beyond commodity gas sales into recovery, recycling, process technology, and specialized infrastructure. Woikoski remains a privately held Finnish industrial brand in the available reference material. Its principal positioning is as an integrated gas supplier and technical partner: it combines gas production and supply with equipment, engineering, distribution systems, and reseller support. The available sources do not provide a current ownership structure, current executive list, official website, or up-to-date financial data.
History
Woikoski traces its origins to 1882, when the business began as a factory producing carbon black, a pigment historically known as lampblack. Carbon black was the company’s original industrial focus, but its activities gradually moved toward gas production and associated engineering. This evolution formed the basis of the company’s later identity as an industrial- and medical-gas supplier. The company’s physical and family history is closely connected with the Voikoski rapids in Finland. In 1909, Alfred A. Palmberg, the son of engineer Knut August Palmberg, acquired a mill on the banks of the rapids and established a millstone factory. Alfred later sold the Voikoski area to his brother Bertil Palmberg. Bertil established a chemical factory and a power plant at the site, with both operations beginning in 1920. Gas production developed as the company’s industrial priorities changed. Hydrogen was produced first, while oxygen emerged as a by-product and was sold for welding uses. This linked chemical production to the growing market for welding and industrial gases. Woikoski eventually broadened its scope to include not only the manufacture and sale of gases, but also equipment and systems for their handling, storage, distribution, and use. The gas works continued under Oy Woikoski Ab, which was founded in 1929. The company became a supplier of technical and medicinal gases and a builder and designer of equipment and distribution systems for the sector. It also imported welding and gas equipment, distributing those products alongside its gases through a network of resellers in Finland. Leadership remained connected to the Palmberg family for much of the documented twentieth-century history. Bertil Palmberg was succeeded by his son Sven Palmberg as managing director in 1948. Sven held the position until 1977 and later received the honorary title of Industrial Counsellor. He was succeeded by his son Clas Palmberg. Woikoski’s later activities included specialized gas processing and recovery. The company exported liquid and gaseous helium and operated an automated helium facility capable of recycling gaseous helium. In 2006, it completed a carbon-dioxide treatment plant intended to recover and recycle approximately one to three tonnes of carbon dioxide per hour. These projects demonstrate a move toward resource recovery and specialized process infrastructure in addition to conventional gas supply. By the period described in the available reference material, Woikoski operated 13 plants and offices and had more than 200 agents in Finland. It supplied industrial and medical gases, imported and distributed welding and gas equipment, and designed systems for gas handling and distribution. The same material reported approximately EUR 41 million in annual turnover for 2012. Because no newer financial or corporate information is supplied here, that figure should be treated only as a historical reference. The available material does not establish a current chief executive, current ownership, exact headquarters address, official website, or a complete international market list. Woikoski is therefore best characterized from the supplied sources as an active Finnish industrial-gas brand and company with a long manufacturing history, a domestic distribution network, export activity in helium, and technical capabilities spanning gas production, equipment, and recovery systems.

Products and positioning
A Finnish integrated industrial- and medical-gas supplier combining gas production, import and distribution of related equipment, and engineering of gas-handling and distribution systems.
Industrial gases
Technical and industrial gases
Woikoski’s core industrial offering comprises technical gases used in manufacturing, processing, welding, and other professional applications. The business grew from hydrogen production, with oxygen produced as a by-product and sold for welding purposes. The company’s role extends beyond gas manufacture to distribution and the design of systems needed to handle and deliver gases safely.
Medical gases
Medical gases
Medical gases form a distinct part of Woikoski’s gas-supply business. The available reference describes the company as a Finnish supplier of medicinal gases, but does not specify individual gas names, packaging formats, regulatory approvals, or current product ranges. The offering is therefore documented at category level rather than as a detailed catalog.
Specialty gases
Helium
Woikoski exports helium in both liquid and gaseous forms. Its helium activities include an automated facility capable of recycling gaseous helium, giving the company a role in specialty-gas processing as well as supply. The supplied sources do not identify specific customer industries, grades, or current volumes.
Industrial equipment
Welding and gas equipment
In addition to producing and distributing gases, Woikoski imports welding and gas equipment. These products are distributed together with the company’s gas products through a Finnish reseller network, allowing the brand to serve customers with both consumable gases and related tools or handling equipment.
Industrial systems and engineering
Gas-handling and distribution systems
Woikoski manufactures, builds, and designs equipment and systems used for gas handling and distribution. This systems capability differentiates the business from a pure gas distributor by connecting supply with storage, delivery, and process infrastructure. The supplied material does not provide named systems, model numbers, or project references.
Gas-processing technology · 2006
