Press Release
Rotor Systems and ELDI Aqua join forces and have established the company Rotor Aqua for next-generation process and digitalization technology in aquaculture.
Location/Date: Bergen, 05.05.2026. Rotor Systems and ELDI Aqua have established the company Rotor Aqua with the purpose of developing, industrializing and commercializing new solutions within process technology and digitalization for the aquaculture industry.
The company builds on a close technological collaboration between the parties, combining Rotor Systems’ technology and development environment within process technology, automation and digitalization, with ELDI Aqua’s industrial experience, global market position and in-depth understanding of operational needs in aquaculture.
Documented collaboration and commercial success
As a basis for the establishment of Rotor Aqua, the parties have over the past two years worked closely together on the development of a new product line for sludge handling in aquaculture – BioSeize. The product line is already in use in the market and has generated significant interest.
BioSeize is developed for more gentle handling of sludge compared to competing solutions, with a particular focus on preserving the quality of the final product. This contributes to increased value of collected sludge, while the solution supports stricter requirements for documentation, biosecurity and sustainability in the aquaculture industry.
“BioSeize system, consisting of FISHIT® and ConeCollect, is a concrete example of what we achieve when technology development and operational experience work closely together. The past two years have shown that this collaboration delivers real value for customers, and together in Rotor Aqua we have a much stronger foundation for further scaling, says Eskil Hansen CEO of Rotor Systems and Thomas Myrvold, CEO of ELDI Group.”

Technology developed for industrial requirements
The aquaculture industry faces increasing requirements for efficient operations, resource utilization, documentation, and sustainability. The partners see a clear need for solutions that provide better control over complex processes, and that can be seamlessly integrated into existing operations.
“Our strength lies in the combination of process understanding, automation and digital tools. With BioSeize, we have developed a solution that handles sludge more gently, while being built for industrial operation and further digital development, says Yngve Askeland, CTO of ELDI Group.”
Further plans
In the first phase, the company will prioritize further development of solutions within sludge handling, process automation, sensor technology and digital platforms. The ambition is to deliver solutions that provide measurable operational and economic value for fish farmers in both the short and long term.
