Square-Shaped Aquaculture Tanks

RAS Fish Tanks for Closed-Circuit Aquaculture Systems

These tanks are specifically designed for Recirculating Aquaculture Systems (RAS) used in closed-circuit fish farms and commercial aquaculture facilities. Engineered for durability, hygiene, and long-term operation, they provide a reliable solution for modern aquaculture production.

Smooth, Aquatic-Safe Gelcoat Surface

The interior and exterior surfaces of the tanks are finished with a gelcoat suitable for aquatic life. This coating provides:

• A smooth, glossy interior surface that prevents waste buildup

• Easy cleaning and disinfection for improved biosecurity

• Optional anti-bacterial gelcoat upon request

• Long-term chemical and biological resistance

Heavy-Duty Support Legs and Reinforcement Options

Depending on load capacity and project requirements, tank support systems can be customized:

• Support legs can be integrated into the tank body or supplied separately

• Legs are manufactured from galvanized steel or fiberglass

• Custom leg heights available to match site and piping layouts

For added strength, metal or plastic reinforcement pipes can be installed around the tank. These reinforcement profiles are coated with polyester and gelcoat, ensuring full compatibility and corrosion resistance.
