The company SEWEC OZON has been founded in March 2012 by the partners Karl J. SENN and Guenter WERNER. Their Know-how is based on about 30 years of comprehensive experience in ozone technology that includes design and manufacturing of ozone generators and ozonation systems as well as virtually each ozone application. Due to the international business orientation the legal form of the company has been transformed to SEWEC OZON GmbH as a consequent step to accommodate future requirements on the worldwide growing markets for water and air treatment. Currently the team of SEWEC OZON consists of 11 highly motivated and qualified persons, some with 20 years plus experiences in manufacturing of ozone generators and maintenance on complex ozone systems. SEWEC OZON is located in an industrial centre of Wehr, a charming town in the southern area of black forest, close to the borders to Switzerland and France.
