Primozone is redefining ozone technology with its high performance cold plasma ozone generators. The Primozone GM-series ozone generators are built on patented cutting-edge technology that enables ozone production with a very high concentration (up to 20 wt%) and at a very high outlet pressure. The GM ozone generators are energy efficient, maintenance free and have a low life-cycle cost.

Primozone was founded in 2000 by the entrepreneur and electro engineer Jan Borgström. He is the brain behind the technique for the high ozone concentration and the energy effective construction. When Borgström worked with ozone generators in the mid-1990s he realized that they were energy consuming, hard to operate and inefficient. Borgström was convinced that he could develop a much more efficient and operator friendly ozone generator and started developing the Primozone Technology.

Since 2003, Primozone Production AB is wholly owned by Westfal-Larsen Technology of Bergen, Norway. The W-L group is a family-owned group of companies founded in 1905. Primozone is one of several companies within Westfal-Larsen Technology AS, all of whom are active within high-technology R&D products. The W-L group is an industrial owner who has invested several million Euros in the development of the Primozone’s Ozone Generator.

Today the Primozone Ozone Generator is a proven concept. It is sold worldwide and used for different industrial water treatment applications in different countries.

Patented technology
The patented, cutting-edge technology behind the Primozone ozone generator is setting the standard for a new generation of ozone generators. The high ozone concentration, the small size and the low life-cycle cost are all features that differentiate the Primozone Ozone Generator from conventional ozone generators. At Primozone we are leading the development of innovate ozone technology for water treatment.

Quality management
At Primozone we are committed to efficient production management and environmentally friendly processes. Primozone is therefore certified according to both ISO9000 and ISO14000 and all products are CE-marked. This is important as all research and development as well as assembly is made in-house at the Primozone facility.

A partner in ozone water treatment
At Primozone a lot of effort has been put into research and development and we are cooperating with different universities and other partners to develop new applications and improve existing ones. The result of this research and cooperation is now an important part of the Primozone offer. At Primozone we are devoted to, not only provide our customers with efficient ozone generators and ozone water treatment systems, but also to provide a lot of knowledge about ozone and its different applications for water treatment. Primozone is a complete partner in ozone water treatment.
