Redox AS has entered into an agreement to acquire Filtra AS, which delivers water and air purification solutions to the aquaculture and maritime industries as well as onshore industrial applications.
Redox is a supplier of oxygen and water treatment systems that contribute towards improving fish welfare and biosecurity in the fish farming industry, while reducing the use of chemicals. The acquisition of Filtra further reinforces Redox’s core water treatment competence and contributes towards strengthening its technology and solutions for water filtration and purification.
‘Filtra is a unique centre of excellence for filtration solutions. The company has extensive experience in the treatment of air, water and fluids, with a strong focus on delivering future‑oriented solutions. Bringing Filtra into the Redox family enables us to offer fish farmers, the maritime sector and other industries an even more comprehensive portfolio of products and services,’ said Redox CEO Asbjørn Skaro.
Filtra is a supplier of products and solutions for the treatment of air, water and other fluids. Within the maritime sector and the aquaculture industry, Filtra delivers a wide range of solutions for particle removal and neutralisation of bacteria and other microorganisms, including UV disinfection of intake water for land‑based aquaculture facilities and treatment of potable water on board vessels.
Filtra’s broad product portfolio includes UV disinfection systems, water treatment solutions, filter housings, filter cartridges and filter bags, automatic filters, chemical dosing systems, carbon filters, RO (reverse osmosis) systems, ventilation filters and potable water coolers. Filtra also delivers service, spare parts and maintenance for its products.
‘After 20 years with Filtra, it is with both pride and a sense of sentiment that I prepare the company for its next chapter,’ said Filtra founder Osvald Ringstad, who will remain with the company until 1st September this year.
‘The strong industrial fit with Redox is clear to see. We share a philosophy of being agile and of developing innovative solutions in close collaboration with our customers – delivering standard products where appropriate and tailored solutions when required. We look forward to becoming part of the Redox family.’
Filtra AS will continue as a separate company, with its headquarters remaining at Skodje.
‘Filtra is a well run company with highly competent people who are experts within their respective niches. That is something we intend to build on. Our goal is to create more activity and, over time, additional jobs,’ said Asbjørn Skaro.
