- 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.
