What Sievert does

Sievert AB is a Swedish manufacturer of professional heating tools, founded in 1881/1882 and headquartered in the Stockholm/Solna area. The company designs and produces blowtorches (Powerjet, Handyjet, Turbojet, Butajet), modular torch systems (Pro 86, Promatic, Pro 88, Pro Venturix, Pro 95), proprietary gas cartridges/cylinders, and accessories such as the Twist 'N' Lock connection system. Its underlying technology centres on controlled flame performance, gas delivery safety, and modular interoperability between torch bodies and fuel sources, areas in which it holds multiple proprietary technologies and has twice received the RED DOT design award.

Sievert operates as a wholly-owned subsidiary of Rothenberger, having been acquired in 2003 after a corporate history that included the 1966 Primus merger, a subsequent split-off from Primus in 2002, and an earlier 1964 acquisition of ESSO's blowtorch division. Manufacturing takes place in Sundbyerg, Sweden (since 1885) and in Estonia (since 1995), with the Estonian site providing a lower-cost EU production base. The company has more recently extended into electrical hot air welding with its Thermoweld product line, broadening the professional use cases it serves.

The business model is hardware sales through an authorized retailer network across Europe and select international markets. End customers are professional trades — plumbers, roofers, electricians, HVAC technicians, chefs, and jewelers — purchasing unit-priced tools and consumable gas cartridges. The company supports this channel with multi-language safety data sheets and a Knowledge Centre providing flame technology and application education, reinforcing its position within its established professional niches rather than pursuing volume consumer DIY channels.
