Oceanus;
16-24 m3 capacity
When you need high uptime and simple operation.
Built for vessels that need reliable, all‑in‑one fresh water.
Oceanus is the “workhorse” of the Signature Series: a complete, ready-to-install RO skid that delivers robust water production for vessels with medium‑sized crews. It’s compact, durable, and engineered for straightforward ships that want high uptime, simple operation, and minimal installation complexity.
Safe Water on Board®
Oceanus forms the first step of the Safe Water On Board® chain
It delivers a consistent, dependable supply of fresh water that flows into your storage tanks, disinfection systems, and tap points. Reliable production means safer water throughout the vessel with lower operational risk for the crew.
Is Oceanus the right RO for your vessel?
Our Oceanus RO Fresh Water Generator is for you if your vessel…
- Runs with medium crews (typically 18+ pax).
- Needs a complete water treatment skid, not loose filters or separate pre‑treatment units.
- Operates on routes where reliability and predictable performance matter more than advanced automation.
- Has limited space but still requires serious capacity (16–24 m³/day).
- Values short delivery times and simple installation, especially during port calls or tight docking schedules.
