History

Woikoski was originally a factory producing carbon black, a pigment formerly known as lampblack, but over the decades its production focus shifted to gas production. Gas production began with the production of hydrogen, with oxygen produced as a by-product and sold for welding purposes. The company also manufactures equipment and systems needed for the handling and distribution of gases.[1][5]

Alfred A. Palmberg, the son of engineer Knut August Palmberg, bought a mill on the banks of the Voikoski rapids in 1909 and established a millstone factory. He sold the Voikoski area to his brother Bertil Palmberg, who established a chemical factory and power plant there, both of which began operations in 1920. The Voikoski gas works continued operations under Oy Woikoski Ab, founded in 1929, which produces technical and medicinal gases and also builds and designs equipment and distribution systems for the field. Bertil Palmberg was succeeded as the company’s managing director from 1948 to 1977 by his son Sven Palmberg, who received the honorary title of Industrial Counsellor, and then by Sven’s son Clas Palmberg.[5]
