What OxyGuard does

OxyGuard International A/S is a Danish designer, manufacturer, and supplier of water quality monitoring and control equipment, founded in 1987 and headquartered in Farum, Denmark. The company introduced the first waterproof oxygen meter for aquaculture in 1987 and has since built a full portfolio spanning probes (dissolved oxygen, CO₂, pH, total gas pressure, salinity, ozone, temperature, redox), handheld meters (Polaris C series), and integrated monitoring/control systems (Pacific, Marlin+, Commander Pacific, Pond Master, Pacific Convoy). All hardware is produced in-house at the Farum facility, which houses SMT production, machining, and final assembly. The company serves aquaculture operators across RAS, pond farming, sea cages, and live fish transport, with secondary use cases in nuclear, military, environmental science, and wastewater applications.

The commercial model is built around a global certified distributor network spanning 65+ countries (with one source citing 120+ countries), supplemented by owned regional offices in Madison, New Jersey (OxyGuard North America) and Gdańsk, Poland (OxyGuard Polska). Revenue is generated through hardware sales, a low-cost subscription to the Cobália digital farm management platform, and maintenance/support services (including a 10-hour emergency technical support service for Commander and Pacific systems). OxyGuard has invested in technology partnerships — notably with Water ApS for the licensed Gaia ozone generator and Helios UV, and with the Technical University of Denmark (DTU) for joint research on AI-driven feeding, ozone treatment, and RAS analytics. The company is privately held, has approximately 50 employees, and has had no disclosed institutional funding beyond a small 2016 EISMEA grant.

Recent strategic activity centres on digital and AI-enabled aquaculture: OxyGuard is developing an AI-powered acoustic monitoring system for fish feeding (recognised with the 2026 AI Denmark Award), expanding ozone-based water treatment for off-flavour compound removal in RAS, and participating in multiple EU- and Danish-funded R&D consortia (BIZON, RASALT, IntelliRAS, VIDA, ProBiOzon, FishEUTrust, SAFE, Biocircular, Treatment Train, FluoRAS). The company holds ISO 9001:2015 certification through 2028, has been a market leader in aquaculture water quality equipment for 35+ years, and is positioning itself as an integrated hardware-plus-software platform vendor for the global aquaculture industry.

Broad incumbents

• Pentair: US-based water solutions company with aquaculture and pool/spa divisions offering filtration, water treatment, and some monitoring hardware. Operates across a much broader portfolio than OxyGuard, but overlaps in aquaculture water quality, treatment (including ozone), and large-farm system integrations.
• Xylem (including Hach and Aanderaa): Global water technology major that owns Hach (water-quality laboratory and process instrumentation) and Aanderaa (ocean monitoring sensors). While serving a far broader water-quality market than OxyGuard, both brands overlap in probes and monitoring systems sold into aquaculture and adjacent industrial water customers.
• Danfoss (including MJK): Danish industrial group with a strong water and climate segment (including former MJK instrumentation) addressing water treatment, wastewater, and aquaculture monitoring/control. Same Danish industrial base and engineering culture as OxyGuard, with overlapping probe and controller product lines but at much larger scale.
• Endress+Hauser: Swiss-German industrial process measurement specialist providing liquid analysis sensors (pH, DO, conductivity) and automation across process industries including water, wastewater, food, and increasingly aquaculture. A broader-scale competitor on the probe and transmitter layer where OxyGuard competes.

Direct competitor in real-time aquaculture sensors and digital farm management, with overlapping customers in salmon RAS and open-net farming.
• Akva Group: Norwegian aquaculture technology group providing hardware, sensors, and software for salmon farming operations globally. Competes head-on with OxyGuard in RAS monitoring, sea cage instrumentation, and digital farm management for aquaculture, serving similar large salmon producers (e.g., Grieg Seafood customer overlap).
• ScaleAQ: Norwegian aquaculture technology provider (formerly Steinsvik) offering feeding systems, sensors, and digital solutions across the salmon farming value chain. Competes directly with OxyGuard on sea cage and RAS monitoring hardware and on integrated farm-management software.
• Bluegrove: Norwegian aquaculture technology company specializing in fish welfare sensors and underwater monitoring (originally part of Akva Group ecosystem). Competes directly with OxyGuard in submersible sensors, fish behavior tracking, and welfare-focused monitoring for salmon and other farmed species.
