BWT LOOPO WFI Storage and Distribution System

• Pharmaceutical manufacturing for drug formulation and active pharmaceutical ingredient (API) production.
• Biotechnology and life sciences for cell culture media preparation and buffer solutions.
• Healthcare facilities for sterile processing and laboratory use.
• Cosmetics industry for high-purity ingredient formulation.

Typical capacity

Storage tanks for WFI systems commonly range from several hundred to several thousand litres, depending on process demand.

Power supply

Units of this type typically require a three-phase industrial power supply, commonly 400V, 50Hz, with specific amperage requirements varying by pump and heating element size.

Operating temperature

WFI storage and distribution systems often operate at elevated temperatures (e.g., 80-90°C) for microbial control, or ambient with periodic sanitisation.

Materials of construction

Product-contact surfaces are typically constructed from 316L stainless steel, with an electropolished finish to meet pharmaceutical standards.

Control system

Modern systems commonly feature PLC-based control with HMI for monitoring parameters such as temperature, pressure, flow, and conductivity.

Sanitisation method

Systems are typically designed for hot water sanitisation (HWS) or steam-in-place (SIP) to maintain WFI quality.

• What is WFI?

  WFI stands for Water for Injection. It is a highly purified water used in the preparation of medicines where water is the vehicle, or for washing equipment that comes into contact with parenteral products.

• Why is a dedicated storage and distribution system necessary for WFI?

• What are the key components of a WFI storage and distribution system?

• How is microbial control maintained in these systems?

• What regulatory standards apply to WFI systems?

WFI generation and storage systems are considered essential infrastructure in pharmaceutical manufacturing. Buyers typically prioritise systems with verified maintenance records, as reliability and consistent water quality are critical. Key considerations include capacity requirements, sanitisation capability, and compliance with relevant pharmaceutical standards. Industry sentiment favours units demonstrating robust construction and proven track records in similar production environments. Used systems often provide good value when sourcing from established manufacturers with documented performance history and complete documentation of previous operating conditions and service schedules.
