VitaDi™ Oxygenation System
Innovation in oxygen transfer for aquaculture
The best diffuser for
dissolving oxygen in
water.
The VitaDi™ oxygenation system is designed to maximize oxygen transfer in Landbased and Sea-based farming sites through high-efficiency, long-lasting micro-perforated diffusers.
It combines stable performance with a modular design adaptable to any aquaculture infrastructure.
MAIN COMPONENTS
- Material: Manufactured in high-durability EPDM with elastic memory, ensuring consistent performance over time.
- Micro-perforations: Calibrated to generate homogeneous micro-bubbles and high oxygen transfer efficiency.
- Service Lifetime: Stable and prolonged, exceeding 5 years.
STRUCTURES AND FRAMES
- Stainless steel frames: 304, 316, and 316L.
- Modular configuration: Custom-designed length, width, and diffuser density.
MAIN PARAMETERS
| Parameter | Value / Range |
|---|---|
| Delivery flow | Seawater: 12 Lpm/m - 1 kg/h/m at 3 Bar(g) |
| Freshwater: 3 Lpm/m - 0.24 kg/h/m at 3 Bar(g) | |
| Operating range | 0.5 – 4 Bar |
| Maximum pressure | 20 Bar |
| Burst pressure | 60 Bar |
| Bubble size | 250 µm (depending on model) |
| O₂ Transfer | High Efficiency (OTE ~ 95%), depending on flow, depth, and medium |

AQUACULTURE APPLICATIONS
| Phase | Application |
|---|---|
| Pre-smolt / Nursery | Maintaining DO in high flows and increasing densities. |
| Sea growing | Support during summer, Harmful Algal Blooms (HABs), stratification, and low oxygen events. |
| Transport and handling | DO stabilization in trucks and wellboats; treatment baths, vaccination, and harvesting. |
VITADI™ SYSTEM ADVANTAGES
| Area | Benefits |
|---|---|
| Efficiency | Finer micro-bubbles ➔ larger contact surface area. |
| Practical operation | Optimized design to operate at lower pressures while maintaining high transfer efficiency. |
| Stability | Maintains stable DO in extreme conditions. |
| Modularity | Adaptable to various cages, densities, and depths. |

Basic instructions
Install diffusers at the
same depth
They must be installed at the same depth and have identical manufacturing characteristics to ensure equitable pressure distribution.
Clean system
Perform manual or chemical cleaning.
Adjust flow
Adjust the flow rate according to the biomass.
Check pressure
Verify reading instruments frequently. Monitor flow, pressures, and valves as required.
