Primus AB

Primus AB is a Swedish manufacturer of portable cooking and outdoor equipment headquartered in Stockholm. The company is principally associated with the Primus stove, a portable kerosene stove developed in 1892 by Frans Wilhelm Lindqvist and Johan Viktor Svenson. The original design was intended to provide a cleaner and more practical alternative to stoves that produced soot, and its early customers included women operating street-market stalls in Stockholm. The product subsequently found an important market among travelers, explorers and mountaineers because it could provide a dependable cooking source away from fixed infrastructure. The brand became closely connected with polar exploration and high-altitude mountaineering. A Primus stove was used during Salomon August Andrée’s 1897 North Pole expedition, and Roald Amundsen carried one on his 1911 South Pole expedition. In 1928, a Primus stove was dropped by a Junkers trimotor aircraft to survivors of Umberto Nobile’s airship Italia expedition, who were stranded on pack ice near the North Pole. The stove’s role in that episode illustrated the practical value of compact, reliable field cooking equipment in extreme conditions. In 1953, Sir Edmund Hillary and Tenzing Norgay also used Primus stoves during the first successful ascent of Mount Everest. Although the stove remains the center of the brand, Primus’s range has expanded into products for outdoor cooking, heating and lighting. Its cooking portfolio includes liquefied-petroleum-gas backpacking stoves, multi-burner camping stoves and multifuel expedition stoves. The company has also offered lanterns, vacuum bottles, cookware, cutlery and other accessories for camping and outdoor use. Its products are positioned around portability, fuel flexibility, durability and performance in demanding outdoor environments. The OmniFuel stove, introduced in 2001, became one of Primus’s notable products. It was designed to operate with several fuel types, including LPG, white gas, kerosene, jet fuel and diesel, making it suitable for users traveling across regions where fuel availability varies. In 2007, Primus introduced the Eta Power line of cooking systems. These systems combined burners, windscreens and pots with heat exchangers to improve fuel efficiency; the Eta name refers to efficiency in physics. In 2012, the company introduced the OmniLite, a smaller and lighter stove derived from the multifuel concept of the OmniFuel and intended for use with Eta pots. Primus stoves and lanterns are sold in more than 70 countries. Its stoves are manufactured at the company’s factory in Tartu, Estonia. On 28 April 2023, Fenix Outdoor International AG announced that it had sold Primus AB to Silva Group. Primus therefore continued as an outdoor-cooking and equipment brand under new ownership, while retaining its historical association with portable stoves and expedition use.

Primus AB traces its origins to 1892, when Frans Wilhelm Lindqvist and Johan Viktor Svenson developed the first Primus stove. The product was a portable kerosene stove designed to burn without the soot associated with earlier portable cooking devices. Its first market was not exclusively the emerging leisure-camping sector: early users included women running street stalls in Stockholm, for whom a compact and relatively clean cooking appliance was useful in daily commercial work. The stove’s portability soon made it valuable to explorers. Primus equipment accompanied Salomon August Andrée’s 1897 North Pole expedition and Roald Amundsen’s 1911 South Pole expedition. These uses helped establish the brand’s association with exploration and demonstrated that a small fuel-burning appliance could support cooking in places where conventional kitchens were impossible. In 1928, a Primus stove was delivered by air to survivors of Umberto Nobile’s Italia airship expedition, who were sheltering on North Polar pack ice. The episode became another illustration of the equipment’s importance in an emergency expedition setting. Primus continued to be used in mountaineering and high-altitude travel. Sir Edmund Hillary and Tenzing Norgay relied on Primus stoves during their 1953 ascent of Mount Everest. Over time, the brand developed beyond its original kerosene stove into a broader outdoor-equipment business covering cooking, heating and lighting. The company’s product range came to include gas stoves for backpackers, larger camping stoves, multifuel expedition equipment, lanterns, vacuum bottles and accessories such as cookware and cutlery. Product development during the modern outdoor-equipment era emphasized fuel flexibility and improved efficiency. The OmniFuel, launched in 2001, was designed to use LPG, white gas, kerosene, jet fuel and diesel. This made it useful for expedition users who could not rely on one standardized fuel source. Primus introduced the Eta Power range in 2007. The Eta systems combined a burner, wind protection and heat-exchanger cookware to reduce heat loss and improve fuel efficiency. In 2012, Primus added the OmniLite, a lighter and more compact multifuel stove designed for use with Eta pots. Primus products are sold in more than 70 countries, and the company’s stoves are manufactured at its factory in Tartu, Estonia. The brand remained part of the outdoor portfolio of Fenix Outdoor International AG until 2023. On 28 April 2023, Fenix Outdoor announced the sale of Primus AB to Silva Group. The transaction marked a change in ownership while leaving Primus focused on portable outdoor cooking and related equipment.
