Storage and Distribution System
WFI must be stored and distributed under strict hygienic conditions to maintain their quality until the point of use. Our storage and distribution system are carefully designed based on the layout of the production facility and the user’s preferred sterilization method. Following the principles outlined in GMP, ISPE guidelines, and FDA regulations, the system ensures safe water handling and minimal risk of contamination. The layout of our pharmaceutical grade water storage and distribution systems maximize the use of available space while maintaining easy access for maintenance and operation. High-quality hygienic piping and fittings are selected to eliminate dead legs and avoid contamination risks. The return loop is designed to maintain continuous circulation, preserving temperature and quality standards across the entire network. Every detail, from piping configuration to system control, supports user validation requirements and ensures reliable long-term operation.
Widely used in pharmaceutical manufacturing, medical facilities, and food production environments.
- Compact modular structure, easy to expand and maintain
- Real-time TOC monitoring to ensure continuous quality control
- Integrated heat exchanger keeps return loop at a stable temperature
- Return flow is automatically regulated for consistent performance
- PID-based thermal balancing avoids sudden temperature fluctuations
- Online conductivity check helps detect anomalies early
- 3D pipeline layout for better space utilization and clean routing
- Accurate calculations ensure system efficiency and compliance
- Pressure simulations help validate pipeline performance
- Fast return flow avoids stagnation and maintains water purity
- All parts in direct contact with the product are made from 316L stainless steel, chosen for its corrosion resistance and suitability in high-purity applications.
- The evaporator, preheater, and condenser are wrapped in aluminum silicate blanket insulation. This material is lightweight, flexible, and excellent at retaining heat, helping maintain stable system temperatures.
- Internal and external surfaces are electro-polished to ensure a smooth finish that reduces contamination risk and simplifies cleaning.
- Components are arranged for space efficiency, allowing for easier installation and maintenance without sacrificing performance.
- The storage and distribution system flow is optimized to make daily operation intuitive and convenient for operators.
- Designed with zero-dead-leg connections and fully automatic argon arc welding. The joints are smooth and consistent, minimizing potential buildup and ensuring a clean process environment.
- Each pharmaceutical water storage and distribution system undergoes pressure testing, acid cleaning, and passivation to ensure reliability and long-term corrosion resistance.
- Endoscope inspection is used to verify internal weld quality and cleanliness before delivery.
- Surface roughness (contact surfaces): Ra ≤ 0.38 μm
- Flow regime: Maintained in turbulent flow with Reynolds number Re > 6000
- Flow velocity (inside piping): ＞1.1m/s
- Endotoxin limit for water for injection: ≤ 0.25 EU/mL
