FRP tank/nitrogen sealed tank

FRP Tanks and Nitrogen-Sealed Tanks are high-performance water storage solutions designed for diverse applications, combining durability, hygiene, and precision control:


Premium Construction: The inner liner is made of sanitary-grade 板材 (sheet material) for safety, while the exterior is reinforced with resin + fiberglass winding—delivering high strength, lightweight design, acid/alkali resistance, and oxidation resistance.


Nitrogen-Sealed Function (for Ultra-Pure Water): Nitrogen-sealed tanks are specialized for storing ultra-pure water (conductivity >10MΩ·cm). They separate water from air by injecting nitrogen, with automatic pressure control via inlet/outlet valves to prevent secondary contamination of ultra-pure water.


Specifications & Customization: Available in total volumes from 0.5m³ to 40m³ (with diameter/height configurations listed), and supporting customization for tanks with diameters ≥3.5m. Key accessories (liquid level gauge, water/nitrogen ports) come in standard DN sizes (DN15 to DN80).


Versatile Applications: Suitable for industrial, commercial, and residential scenarios—including ultra-pure water storage, drinking water supply, water treatment, fire water systems, and other water storage needs.

These tanks balance reliability, adaptability, and hygiene, making them ideal for both standard and specialized water storage requirements.
