STORAGE &
DISTRIBUTION SYSTEM for
PW / WFI
Storage & Distribution System is required to store and distribute the PW / WFI within the plant. The system ensures stringent quality parameters of Pharmaceutical / Biotech industry. The distribution system is a closed loop system. Closed loop system ensures integrity of the PW & WFI. The entire Storage & Distribution System parameters are monitored & controlled with the help of instruments & equipments mounted on Distribution Skid.
APPLICATIONS
PW / WFI Storage & Distribution System is required for
• Purified Water / WFI Storage
• Distribution of Purified Water / WFI
• For Sanitization of PW Tank & Distribution Loop
• Controlling Microbial Load in WFI / PW
• Rejecting High Conductivity PW / WFI
• Sterilization Process Management
WFI Tank & Distribution Loop
Features

• All weld joints in the loop are orbital welded using high purity (99.99%) argon gas and can be inspected by boroscopy machine
• Complete set of documentation and certificates to ensure compliance with regulatory authority. We provide DQ, OQ, IQ, FAT & SAT. Also assist client to develop PQ
A system designed to store and circulate Purified Water (PW) or Water for Injection (WFI) throughout pharmaceutical or biotech facilities, ensuring consistent water quality at all user points.
It prevents microbial growth and maintains water quality by eliminating stagnation, typically with loop velocities ≥1 m/s.
Pharmaceuticals, biotechnology, injectables, cosmetics, food & beverage, and personal care sectors, where ultra-pure water is critical to product safety and compliance.
