Tested & CFD-validated
Biofilter, flow and bottom-drain design proven in the field and in simulation — not theory.

The Single Tank Design.
Conventional RAS means many tanks, long pipe runs, a big building and a big crew. The Single Tank Design puts it all into one CFD-validated tank-in-tank unit that recirculates over 94% of its water — so you build for less and run with fewer people.
Less to build. Less to run.
Conventional RAS
- Many separate tanks and long pipe runs
- A large building for the same volume
- High build cost per cubic metre
- Pumping losses across the whole loop
- A large crew for round-the-clock operation
Single Tank Design
- One tank-in-tank unit with 95% less piping
- 15–20% smaller footprint with the octagonal geometry
- About 30–35% lower investment
- Under 2 kW per kg of fish (excl. heat)
- 24/7 operation with a 3–4 person crew

Proven where it matters.
Closed-loop, low piping
Site-dependent 90%+ recirculation and ~90% less piping.
Fresh, salt, any climate
Cold or warm, freshwater or marine; multi-species ready.
AI-driven water quality
Ships with Suderra Edge: an AI-assisted live water-quality panel for fast, data-driven decisions.
See the platform →Fully automatic feeding
Scheduled, self-dosing feed delivery across every tank.
Species-adaptive tuning
Stocking density, water velocity and biofilter sizing tune dynamically per species.
24/7 with a lean team
The whole site runs around the clock with a 3–4 person crew.
Uptime & IP-secured
Service without downtime; proprietary, protected design and software.
From a single tank to a full facility.
