FRP nitrogen-sealed water storage tank – Specialized for ultra-pure water/high-purity water. Nitrogen protection. Automatic pressure control.
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.

Product Features
High strength, lightweight, resistant to acids and alkalis, and anti-oxidation.
【Product Overview】
The FRP (Fiber Reinforced Plastic) water storage tank/nitrogen-sealed water tank series is a lightweight, corrosion-resistant, and high-strength water storage container made by combining a sanitary-grade resin inner liner with a high-strength glass fiber winding layer. This series includes two core types: the standard atmospheric pressure type water storage tank and the dedicated nitrogen-sealed (nitrogen protection) type water tank. The standard type is widely used for the safe storage of clean water, reclaimed water, raw water, etc.; while the nitrogen-sealed type water tank effectively isolates air by injecting and maintaining a certain pressure of inert nitrogen (N₂) into the tank top space, preventing the conductivity of ultra-pure water or high-purity water from increasing due to contact with air during storage (secondary pollution), making it an ideal solution for storing sensitive media in industries such as electronics, photovoltaics, semiconductors, and pharmaceuticals.
【Product Features and Advantages】
Dual types, precise matching: Offer standard water storage tanks and professional nitrogen-sealed water tanks. The nitrogen-sealed type is specially designed for storing high-demand media such as ultra-pure water. Through nitrogen isolation technology, it eliminates the increase in electrical conductivity caused by the dissolution of carbon dioxide and oxygen, ensuring stable water quality of the discharged water.
Outstanding material properties: The FRP material combines high strength with lightweight (its weight is only a fraction of that of concrete water tanks), and it has excellent resistance to acid, alkali, salt corrosion and oxidation, with a long service life and low maintenance costs.
Hygiene and safety, smooth inner wall: The inner wall is lined with a sanitary-grade resin, meeting the hygiene requirements for water storage; the inner wall is smooth, making it difficult for algae and microorganisms to grow, and easy to clean.
Reliable structure, complete interfaces: Utilizing advanced winding technology, the structure has high strength. It provides a complete range of standard interfaces (such as liquid level, water inlet and outlet, exhaust, nitrogen, etc.), facilitating system integration and automated control.
Support for deep customization: It supports customization in aspects such as volume, diameter, height, interface position and specifications, to meet the space layout and process connection requirements of different projects.
【Typical Application Scenarios】
Standard FRP water storage tanks: Storage for tap water, reclaimed water, and fire water; Raw water tanks, production water tanks, and concentrated water tanks for reverse osmosis systems; Temporary water storage for various projects.
FRP nitrogen-sealed water tank: Terminal storage and transportation of ultra-pure water (UPW) for electronics, semiconductors, and photovoltaic industries; high-purity water storage for the pharmaceutical industry; laboratory central water supply system; any storage process with extremely high requirements for water purity.
