  • SOLVOX® C is a pressure dissolver for fresh and sea water. Designed to increase the concentration of oxygen in water, it is made from corrosion-resistant glass-fibre-reinforced plastic (GRP) with high-quality stainless steel fittings. Various SOLVOX® C design innovations achieve transfer efficiency rates close to 100%.

    As water and gas enter the SOLVOX® C cone from the top, the water jet forces the water to mix intensively with the oxygen bubbles. As the cone widens, the velocity is reduced. Small gas bubbles that are not yet fully dissolved rise in the cone against the downward water flow, so only water free from gas bubbles leaves the cone at the bottom. Since the SOLVOX® C cone is operated at elevated pressure, the dissolved oxygen concentration can be increased significantly above normal saturation levels.

    Highlights of SOLVOX C

    • Oxygen transfer efficiency rates close to 100%
    • Ability to increase oxygen saturation well above the normal level
    • Reliable design
    • Cylinder and bulk supply schemes to suit individual needs

  • SOLVOX® OxyStream is a low-pressure oxygenation system for sea water, brackish water and fresh water tanks.

    The system is a patented all-in-one product, which oxygenates the water and evenly distributes it around the fish tank using an adjustable flow regime. This regime aligns circulation speed with the fish species and size. SOLVOX OxyStream includes a water flow indicator, which gives you a quantitative overview of the water flow into each tank.

    The microbubbles created by SOLVOX OxyStream not only allow for a highly efficient oxygen dissolution but also reduce the concentration of dissolved nitrogen and the total gas pressure of the water. This often eliminates the need for external degassing units.

    SOLVOX OxyStream achieves maximum effect beginning at about 15% salinity and requires a pressure of only 0.05–0.2 bar to oxygenate the water, strip nitrogen and create optimal tank hydrodynamics for fish production. The low-pressure delivery mechanism makes the system very energy-efficient.

    In fresh water installations, SOLVOX OxyStream can be combined with SOLVOX C to meet even the highest oxygenation demands.
