Following a full year of field testing, Freya stabilizes oxygen during stressful events like harvest and high temperatures, helping producers improve fish welfare and reduce oxygenation costs by up to 41%
Hawthorne, Calif., August 19, 2025 – Moleaer Inc., the global leader in nanobubble technology, today announces the global launch of Freya, its first fully submersible nanobubble system for aquaculture. Freya is designed to dramatically improve oxygen delivery, reduce costs, and enhance fish welfare. The system is the result of years of development, more than a year of extensive field testing, and competitive trials in some of the world’s most demanding aquaculture environments.
With rising sea temperatures and stricter environmental regulations challenging the industry, traditional oxygenation solutions often struggle to keep pace. Freya addresses these challenges with advanced nanobubble technology that delivers over 50 kg/hr of oxygen at more than 85% transfer efficiency, in a compact, low-energy, submersible unit. This enables operators to cut oxygenation costs and energy consumption. Field trials have demonstrated that Freya can reduce oxygen usage by up to 41% and lower oxygenation-related energy use by up to 60%, strengthening oxygen management in both daily operations and emergency conditions.
The system has already proven its value with leading producers. At Salmar Innovanor in Norway, Freya quickly doubled dissolved oxygen (DO) levels during harvest, allowing more intensive crowding without compromising welfare and improving fish processing quality. Maintaining DO in high summer temperatures had been a challenge, but with Freya, SalMar Innovanor has been able to fully utilize its waiting pens even under warm conditions.
In Chile, Freya was tested in net pens against industry-leading solutions, achieving dramatic reductions in oxygen usage while maintaining higher dissolved oxygen levels, improving fish welfare, and preventing mortalities.
Freya’s rapid adoption includes new commercial agreements, including Salmon Evolution, a leader in land-based salmon farming, which selected Freya for emergency oxygenation across twelve tanks at its Indre Harøya facility. Chosen after competitive testing, the system will provide rapid, reliable oxygen stabilization to maintain welfare and production efficiency during high-demand events.
These results reflect a broader shift away from traditional systems and diffusers, which often lack the efficiency and responsiveness needed for today’s aquaculture demands. Freya integrates Moleaer’s proprietary nanobubble technology to produce nanoscopic bubbles that stay suspended longer, delivering oxygen more efficiently than traditional systems. This enables precise oxygenation with lower gas and energy input, all in a seamless design that can be deployed in nearly any system configuration.
As the aquaculture industry faces growing pressure to balance welfare, sustainability, and profitability, systems like Freya offer a practical, proven path forward.
Moleaer will be showcasing Freya at upcoming aquaculture industry events at Aqua Nor and Aquaculture Europe. To learn more about Freya, visit: moleaer.com/en-us/products/freya
