Food Grade Stainless Steel Water Storage Tank

This food‑grade stainless steel water Storage Tank is engineered for the safe and hygienic containment of potable water, purified water, and process water in food processing, pharmaceutical, beverage, and industrial facilities. Constructed from high‑grade SUS304 or SUS316L stainless steel, the tank delivers exceptional corrosion resistance and maintains water purity without leaching contaminants. The interior surface is mirror‑polished to a sanitary finish (Ra ≤ 0.4µm), preventing bacterial growth, resisting scale adhesion, and simplifying CIP (clean‑in‑place) procedures. The standard package includes a temperature sensor for thermal monitoring, a digital or glass‑tube level gauge for accurate liquid level measurement, a 600mm manhole for easy internal access and maintenance, and PU insulation to minimize thermal loss. Capacities range from 50L to 100,000L, with customisation options for vertical/horizontal orientation, above‑ground or buried installation, and additional jacketed heating/cooling layers. Backed by over 20 years of stainless steel vessel manufacturing expertise and ISO 9001 certification, every unit is pressure‑tested and certified before delivery, ensuring compliance with international hygiene and safety standards.

• Food‑Grade Sanitary Construction: Manufactured from SUS304 or SUS316L stainless steel, the tank is designed specifically for potable water storage. The material is non‑toxic, non‑leaching, and meets international food contact standards, ensuring that stored water remains pure and safe for consumption.
• Mirror‑Polished Inner Surface: The internal surface is finished to a sanitary mirror polish (Ra ≤ 0.4µm), which prevents bacterial growth, resists scale and biofilm adhesion, and enables quick and thorough cleaning. This feature is critical for pharmaceutical, food, and beverage applications where water purity is paramount.
• Corrosion & Scale Resistance: Stainless steel offers superior resistance to corrosion, pitting, and scale formation compared to carbon steel or plastic alternatives. This ensures long‑term durability, minimal maintenance, and consistent water quality over decades of service.
• Thermal Insulation System: The polyurethane (PU) foam insulation layer effectively minimizes heat exchange with the environment, maintaining stable internal water temperatures. This reduces energy consumption in hot‑water storage applications and prevents freezing in cold environments.
• Heating/Cooling Jacket (Optional): An optional jacket layer allows the tank to be heated or cooled as required, making it suitable for processes that involve temperature‑sensitive water use.
• Real‑Time Monitoring Instruments: The standard instrument package includes a temperature sensor for continuous thermal monitoring and a level gauge (available in digital display or glass‑tube type) for accurate liquid level measurement.
• Easy Maintenance Access: A 600mm manhole provides convenient entry for routine inspection, cleaning, and maintenance. The manhole cover is sealed with high‑quality food‑grade gaskets to ensure airtight closure and prevent contamination.
