Marine and industrial products:
The founder – Reidar Frölich Braathen – started “Oslo Sveisebedrift, Oslo” (OSO) in Oslo in 1932, as one of the first welding shops in Norway. Frölich Braathen was both a blacksmith and a lieutenant in the Norwegian air force and among the first in the country who mastered both electric and autogenous welding. With minimal resources he created the first Norwegian welded water heater. Thanks to his continuous innovation and dedication Frölich Braathen employed 100 people by 1940. His 50 years of experience became the foundation of OSO Hotwater AS – a Norwegian industrial adventure.
2nd generation – Chris Reidar Braathen – was very much involved in restoring the factory after the war. In 1964 Chris Reidar established OSO factory by the Drammen river, where the production of water heaters is still located today. Chris Reidar was a technician and had great commitment and drive, in addition to idealistic ideas. He has, during his more than 50 years in OSO, combined industry and environmental protection in a unique way and has given OSO the recognition as one of the leading environmental enterprises in the Nordic countries, something which has led to several environmental awards and accolades.
3rd generation – Sigurd Braathen – continues to lead OSO with a clear objective to still be a family business located in Norway. Dedicated to improving OSO products and processes, Sigurd continues to build the company brick by brick, and is proud of the fact that OSO has become one of the most robotized companies in Norway. The pioneering spirit lives on with product innovations featuring integrated solutions, ground-breaking material technology and added value for our customers.
THE COMPANY HAS THREE MAIN MARKETS:
A NORWEGIAN INDUSTRIAL ADVENTURE THROUGH 3 GENERATIONS:
OSO was one of the first environmental enterprises in Norway with more than 50 years of efforts and investments to unite people, environment and industry. The emphasis on the environment started with Reidar Braathen Jr. in 1956. He created “The most environmental company in Scandinavia” (SCANVAC award). After 50 years of continuing effort for both indoor and outdoor environments, GRIP together with the Minister of Environmental Protection, Arild Hareide, awarded the special “Glassbjørn”-award to OSO for our effort to save the environment.
Thanks to the loyalty of our customers, OSO has become renowned for best practice for both its manufacturing of water heaters as well as environmental protection. Products with extremely long lifecycle, and the lowest heat loss of any storage tanks on the market are some of our biggest contributions to the environment, in addition to zero-emission production and no toxic waste released of any kind. Love and care for nature is the basis for our engagement in protecting the environment, our objective is the same today as 50 years ago: PROTECT OUR BEAUTIFUL PLANET.
Among the most important environmental efforts are:
The OSO Environmental Fund has contributed to these projects:
OSO Hotwater AS is since 2015 the most robotized manufacturing company in Norway. This has been necessary to keep our business in Norway instead of moving production to low-cost countries as is done by many manufacturing companies these days. By leaving the heavy lifts and repetitive tasks to robots we have liberated the human resources for more constructive tasks, while in the process creating a working environment where health and wellbeing is in focus. OSO has won several awards for our working environment, and is certified in this area in accordance with ISO 45001.
Over 85 years OSO Hotwater has earned the trust from suppliers, co-workers and customers. We are still going to earn, and manage, this trust in an exceptionally good way, and value the opinion of our partners.
