WFI cold storage and distribution

Cold water for injection (WFI) storage and distribution systems typically have two P-line series exchangers installed.

The first one protects the system against excessive increase of temperature, cooling it to 15°C – 30°C. The second is used in the process of periodically heating water to a high temperature in order to sterilize the system.

Another WFI cold water storage and distribution solution is a system with one P-line exchanger, which fulfills both functions. If required, cold water from an aggregate or technological steam is supplied on the shell side.
