The best GMP WFI system mainly includes three parts: preparation system, distribution system and water point, each of which plays an important role. Let's first look at the preparation system of water for injection. The preparation process in the best GMP WFI system that is often used in the domestic market is a multi-effect distillation process, and the multi-effect distilled water machine used is mainly composed of a condenser, a preheater and an evaporator.

The condenser of the  best GMP WFI system adopts a double-plate tube structure to prevent cross-contamination. Control the effluent temperature of distilled water within the specified range, and also make the raw water heated for the second time. The preheater of the  best GMP WFI system is mainly to allow the raw material water to be heated up in a step-by-step manner before entering the evaporator, and the temperature of the raw material water after passing through the final effect preheater can be raised to above 90 degrees Celsius.
Evaporators for the best GMP WFI system are available in single-effect and multi-effect types, where the effect is energy efficiency. The 1-effect evaporator adopts a double-plate tube structure, and the unevaporated concentrated water is automatically discharged at a high liquid level. 2-effect to 4-effect adopts veneer tube structure to prevent cross-contamination. The  best GMP WFI system evaporator adopts the principle of falling film evaporation, and the spiral gravity separation removes impurities and endotoxins.
