FRP dissolved(enhanced) oxygen cone

FRP Dissolved Oxygen Cones are specialized aeration equipment designed for water treatment and aquaculture scenarios, delivering efficient oxygen dissolution:


Key Performance: The working pressure is 0.25MPa (factory test pressure: 0.4MPa), with an operating temperature range of 1°C–49°C (34°F–120°F). Available in diameters from 250mm to 1200mm, it’s constructed from high-strength FRP material, suitable for seawater and other corrosive liquid environments.


Efficient Structure: Its big-end-up conical design enables superior oxygen dissolution performance, with 20°C oxygen dissolution capacities ranging from 1kg/h to 5.6kg/h (depending on the model), and outlet dissolved oxygen concentrations up to 65kg/L.


Specifications: Models (CD25 to CD125) cover flow capacities from 7m³/h to 140m³/h, paired with 25mm–110mm water inlet/outlet flanges and adjustable air pressure (10/15/20 PSI).


Target Applications: Ideal for aquariums, aquaculture farms, seawater breeding seedlings, large temporary aquaculture bases, and other water-related scenarios.

This oxygen cone combines corrosion resistance, high efficiency, and adaptability, making it a reliable choice for oxygenation needs in aquatic systems.
