WFI

The WFI system is the top priority in GMP certification. At present, the multi-effect distillation machine is the most common preparation module of water for injection.

WFI system

After the raw water is processed by the multi-effect distilled water machine, the distilled water that has passed the conductivity test can be used as water for injection, and the unqualified distilled water will be automatically discharged.

WFI skids

The most common process for preparing WFI skids is the multi-effect distillation process, the core device of which is a multi-effect distillation machine.

Water distillation system

Distillation is the preferred method for preparing water for injection recognized by all countries in the world. It has a long history and reliable results.

WFI plant

The WFI plant is mainly composed of an evaporator, a preheater, a condenser, and an electrical automatic control part. The evaporator adopts the principle of vertical tube falling film evaporation. In order to ensure the quality of distilled water, a special steam-water separation device is installed in the evaporator.

WFI module

WFI module also called WFI Pipeline distribution systems should be constructed to allow for the continuous circulation of water in the pipes and to be regularly cleaned and disinfected. A continuously cycling system tends to maintain normal operation.

WFI generation system

Water for injection: Purified water is used as raw water, distilled through a specially designed distiller, condensed and cooled, and then prepared by membrane filtration. Water for injection can be used as a solvent for the preparation of injections.

WFI equipment

WFI equipment can be obtained by distillation method, reverse osmosis method, ultra-filter method, etc. Various countries have made very clear regulations on the production method of water for injection.

WFI distribution skid

Open the cooling water control valve of the WFI distribution skid, so that the reading of the cooling water pressure gauge reaches 0.2 ~ 0.3MPa (according to the cooling conditions, it can be adjusted to be lower than this number), and at the same time, open the valves of the primary condensate discharge valve and the emptying valve by 45 degrees .

Water distiller for injection

The working principle of tube-type Water distiller for injection, the qualified raw water is pressurized by the multi-stage pump and then enters the condenser for heat exchange, and then enters the preheater of each effect in turn, and then enters the first-effect evaporator and is sprayed in the heating tube by the feed water distributor.

Water distiller

Water distiller has beautiful appearance, reasonable structure, steam saving and water saving, and easy operation, the multi-effect distilled water machine is highly praised by users. It is widely used in hospitals, pharmaceutical factories, chemical research institutes to prepare distilled water. This water distiller for injection is used to produce distilled water for injection, and its water quality complies with the regulations of the Pharmacopoeia of the People's Republic of China on distilled water for injection.
