Water for Injection (WFI) complies with the specifications defined in the Chinese Pharmacopoeia. It is produced by distilling distilled water or deionized water, hence also known as "double-distilled water". To effectively control microbial contamination and endotoxin levels, the design and manufacture of purified water and WFI systems feature two key innovations:
- Increasing adoption of disinfection/sterilization facilities within the system;
- Evolution of pipeline distribution from traditional supply pipes to circular loop pipelines, minimizing stagnation risks.
- The WFI preparation, storage, and distribution system is engineered to prevent microbial growth and contamination.
- Tanks and pipelines are constructed from non-toxic, corrosion-resistant materials, with designs free of dead ends and blind pipes to ensure hygiene.
- Regular cleaning and sterilization cycles are specified for tanks and pipelines.
- The WFI storage tank's vent is equipped with a hydrophobic sterile filter to prevent fiber shedding.
- Storage options include thermal insulation at ≥80℃, thermal circulation at ≥70℃, or cold storage at ≤4℃.

VI.Here is a guideline for you to get a proper quotation
Tell us the raw water/source of water(tap water, well water, or sea water, etc)
Provide water analysis report(TDS , conductivity, or resistivity, etc)
Required production capacity( 5m³/H, 50m³/H,or 500m³/H, etc)
What's the pure water used for( industrial,Food and Beverage,or agriculture, etc )
