Conical-Bottom GRP (Glass Reinforced Polyester) Fish Tanks for Recirculating Aquaculture Systems (RAS)
Our conical-bottom GRP fish tanks are specifically designed for recirculating aquaculture systems (RAS). These tanks provide high efficiency in waste management, water circulation, and bottom cleaning, making them indispensable components of modern aquaculture facilities.
Advantages of the Conical Bottom
The conical bottom design allows organic waste and sediments that accumulate on the tank floor to be easily collected and drained. As a result:
Automatic and manual bottom cleaning is more efficient,
Water quality is maintained and fish health is improved,
Feed and waste costs are reduced.
Interior Surface Suitable for Living Organisms
All our tanks feature a special gelcoat coating on both the interior and exterior surfaces that is compatible with living organisms:
Surfaces are glossy and smooth, resisting bacterial adhesion.
Anti-bacterial gelcoat can be applied upon request.
Provides long-term chemical and biological resistance.
Modular and Robust Support Structure
The support system can be implemented in the following ways, depending on the tank’s load capacity and project requirements:
Legs can be manufactured as integrated with the body or as separate components.
Support legs are available in galvanized iron or fiberglass.
Leg heights can be customized to match the tank’s drain slope.
To enhance environmental durability, plastic or galvanized pipe supports can be installed around the tank. These pipes are also coated with polyester and gelcoat to match the tank body.
Project-Specific Production Flexibility
Our conical-bottom tank production is not limited to standard sizes. Since we manufacture our own composite molds, we offer the following advantages:
Custom diameters, heights, and cone angles tailored to your project,
Special gelcoat and color options,
Full compatibility with technical details such as drain valves and pipe inlets/outlets.
