Moleaer has announced the international launch of Freya, its first fully submersible nanobubble oxygenation system tailored for the aquaculture industry.
Designed to tackle rising environmental and operational challenges, Freya aims to revolutionise oxygen delivery, reduce energy and gas costs, and enhance fish welfare.
The system delivers over 50 kg/hr of oxygen with more than 85% transfer efficiency to produce microscopic gas bubbles that remain suspended longer than conventional bubbles. Results from over a year of field testing show up to 41% reduction in oxygen use and 60% decrease in oxygenation-related energy consumption.
“The industry has been looking for a solution that improves oxygen delivery while lowering energy and operating costs, and protecting fish welfare,” said Warren Russell, chief commercial officer at Moleaer.
“Freya delivers on all counts, combining proven performance, lower oxygenation energy use, and a flexible, fully submersible design that works in virtually any aquaculture environment.”
In Norway, SalMar Innovanor deployed Freya during high-temperature harvests, doubling dissolved oxygen levels and enabling denser fish crowding without compromising welfare. In Chile, head-to-head trials in net pens revealed superior DO performance and fish health compared to conventional systems.
Freya’s rapid adoption includes a commercial agreement with Salmon Evolution, which selected the system after competitive testing for emergency oxygenation across twelve tanks at its Indre Harøya land-based facility.
