The distribution method of the GMP WFI system from China can choose a continuous series circulating water supply process to prevent the growth of microorganisms in the distribution system. The distribution system of the GMP WFI system consists of a heat exchanger, a water for injection tank and a transfer pump.

The heating double tube sheet heat exchanger of the GMP WFI system is used to control the return water temperature, circulate heat preservation and regularly superheat water disinfection. The water for injection tank in the GMP WFI system from China is used to store the water produced by the distilled water machine, buffer and provide water for the terminal water point. Water for injection tanks usually use vertical thermal insulation pressure tanks to meet the requirements of water for injection. The delivery pump of the GMP WFI system from China can provide power for the water point, meet the water flow and pressure requirements of the workshop, and prevent the growth of microorganisms.
 The using water points in the GMP WFI system are usually divided into high temperature water and low temperature water. Low-temperature water is usually cooled by double-plate tube shell-and-tube heat exchangers. The cooling method of the GMP WFI system from China generally adopts the branch pipe network circulation method, which is automatically controlled. The design and selection of the water point also needs to consider the disinfection and sterilization method of the entire GMP WFI system from China. Usually, the water point can be sterilized by high-temperature superheated water and pure steam.
