The distilled water produced by this equipment has stable quality, high purity and no pyrogen. It is the key equipment of the widely used water injection preparation system. The multi-effect water distiller adopts high temperature and high-pressure operation to ensure stable production of pyrogen-free water for injection. The distilled water produced by the multi-effect water distiller fully meets the requirements of the current US Pharmacopoeia, European Pharmacopoeia, Japanese Pharmacopoeia and Chinese Pharmacopoeia for water for injection.

The two methods for cleaning the multi-effect distilled water machine areas follows:

1. For boiler scale, sulfamic acid (NH2SO2OH) can be used, and deionized water is used to prepare a cleaning solution with a concentration of 1%. The pH value is between 1 and 2 and heated to about 60°C. Phosphoric acid (H3PO4) can also be used. Use deionized water to prepare a 2% concentration cleaning solution and heat it to about 65°C.

2. For silica scale, ammonium difluoride (NH4HF2) can be used, and deionized water is used to prepare a solution with a concentration of 1.5% and heated to 50℃~60℃. It can also use sodium hydroxide + anionic active agent to prepare a cleaning solution with a concentration of 10% and heat it to about 60°C.
