Redox

What Redox does

Redox AS is a Norwegian water treatment technology company founded in 2004 and headquartered in Averøy, Norway, specializing in chemical-free water and air treatment systems for the aquaculture, maritime, and land-based industrial sectors. Its product portfolio spans seven core technology lines: PSA/VSA oxygen generation systems (with up to 80% cost savings vs. liquid oxygen), Redoxzon proprietary ozone disinfection systems (using Veolia generators), NVI-approved UV disinfection systems, reverse osmosis freshwater production, pressure filtration, marine-grade compressed air systems, and automated washing systems. All products are delivered as plug-and-play containers or site-installed systems with integrated automation and cloud-based monitoring (Redox Cloud), and the company holds regulatory approvals including NVI certifications and a 2004 first-of-kind approval for ozonated seawater in aquaculture.

The company generates revenue primarily through hardware sales (complete water treatment systems), recurring service and maintenance contracts (24/7 support, spare parts, upgrades), and flexible pricing options including purchase, lease, or pay-per-kg O2 usage models. Redox employs a sales-led, enterprise field sales model with dedicated sales managers for the Vessel, Land, Reverse Osmosis, and Oxygen segments, serving aquaculture operators, fishing vessel owners, well boat operators, and industrial customers. Since 2022, Redox has been majority-owned by Bluefront Equity (a seafood-focused private equity firm), which has funded an active acquisition strategy including Norluft AS (2021), Redoxzon Aqua India subsidiary (2020), Trykkluftservice AS (January 2026), and Filtra AS (May 2026). The company operates primarily in Norway with expansion into India and references to Iceland, targeting fish welfare, biosecurity, and chemical reduction outcomes for aquaculture operators globally.

Scale indicators7 records

Recent moves8 records

Expansion highlights6 records

Regional players

• Steinsvik (Akva Group subsidiary): Norwegian aquaculture technology supplier now part of Akva Group, offering sensors, feeding, and water quality equipment to Norwegian salmon farmers. Comparable in Norwegian market focus and customer overlap, with a different product mix weighted toward instrumentation rather than treatment systems.

Direct peers

• Aqualyng: Norwegian-origin RAS specialist providing turnkey land-based aquaculture systems including water treatment. Closely comparable to Redox's land-based segment with shared customers in Norwegian and international salmon smolt production.
• AKVA Group: Norwegian-listed aquaculture equipment supplier offering cage systems, sensors, feeding, and water quality technology to the same Norwegian salmon farming customers Redox serves. Highly comparable in geography and customer base, though broader in scope beyond water treatment.
• Krüger Kaldnes (Veolia): Norwegian water treatment company owned by Veolia Water Technologies, specializing in aquaculture, RAS, and industrial water treatment. Most directly comparable peer in Norwegian water treatment with similar customer base and technology stack.
• Billund Aquaculture: Danish-headquartered global supplier of RAS (recirculating aquaculture systems) and water treatment for land-based fish farming. Directly comparable to Redox's RAS/land segment with overlapping ozone, filtration, and oxygenation technologies and similar customer profile of land-based salmon and smolt producers.
• Innovasea: North American-headquartered aquaculture technology company providing fish farming equipment, water monitoring, and biosecurity solutions. Comparable to Redox in serving commercial aquaculture operators with integrated water quality and oxygen technology.

Broad incumbents

• Pentair: Global water treatment and flow technology company serving aquaculture, industrial, and residential markets with filtration, disinfection, and pumping products. Broad incumbent with overlapping capabilities but no Norwegian aquaculture-specific specialization.
• Veolia Water Technologies: Global water treatment technology giant that supplies Redox with ozone generators under an exclusive Norwegian partnership and also competes in aquaculture water treatment via its Krüger Kaldnes subsidiary. Most directly comparable incumbent given overlapping product lines and customer segments in RAS and municipal/industrial water.
• Xylem: Global water technology company offering pumps, treatment, and disinfection solutions including UV and ozone systems applicable to aquaculture and industrial water markets. Larger and broader portfolio than Redox but competes on similar underlying technologies.

Emerging players

• Hesy Aquaculture: Dutch-based aquaculture water treatment specialist focused on RAS and recirculation systems with comparable oxygenation, filtration, and disinfection technologies. Smaller and geographically focused on European markets, with emerging international reach.
