Operation and maintenance of tubular multi effect distilled water machine
Date: 2025-08-22Read: 2
The tubular multi effect distilled water machine is currently a key equipment widely used in injection water preparation systems. The multi effect distilled water machine adopts high temperature and high pressure operation to ensure stable production of injection water without heat source. The distilled water produced by the product meets the requirements for injection water in the current United States Pharmacopoeia, European Pharmacopoeia, Japanese Pharmacopoeia, and Chinese Pharmacopoeia.

The tubular multi effect distilled water machine is widely used in fields such as pharmaceuticals, biotechnology, hospital preparations, cosmetics, and electronics industries that require high water quality. In the pharmaceutical industry, it is mainly used to produce water for injection (WFI) as specified in the Chinese Pharmacopoeia, the United States Pharmacopoeia (USP), and the European Pharmacopoeia (EP). It is a core equipment in the production process of sterile drugs, infusion solutions, vaccines, biological products, etc. In addition, it is commonly used in laboratory, medical device cleaning, and semiconductor cleaning processes to prepare high-purity distilled water, ensuring product safety and process stability.

  Product Features:

This device adopts the principle of multi effect thermal energy cascade utilization, usually with a three effect to eight effect structure, significantly reducing steam and cooling water consumption and achieving outstanding energy-saving effects. The design of the tubular heat exchange structure is reasonable, with high heat transfer efficiency, stable operation, and easy cleaning and sterilization (compatible with CIP/SIP systems). The whole machine is mostly made of 316L stainless steel, with electrolytic polishing treatment on the inner surface, in compliance with GMP and ASME BPE standards, effectively preventing secondary pollution. At the same time, equipped with a PLC fully automatic control system, it can achieve online monitoring of water quality, parameter recording, and fault alarm, ensuring that the quality of produced water continues to meet the requirements of the pharmacopoeia, and has the advantages of high efficiency, energy saving, safety, and intelligence.

The operation and maintenance of a tubular multi effect distilled water machine should follow the following steps:
operating steps
1. Preparation stage
Check the cleanliness of the equipment to ensure there is no residual dirt. ‌
Connect the power and water sources, and confirm that the interface is functioning properly. ‌
Prepare a container to collect distilled water. ‌
2. Start the process
Turn on the power switch and preheat to the set temperature. ‌
Adjust control panel parameters (such as temperature, pressure). ‌
Open the water source valve and observe the generation of water vapor. ‌
3. Operation management
Regularly check the water level and temperature to avoid abnormal fluctuations. ‌
Collect condensed water into a container and pay attention to the hygiene of the storage environment. ‌
4. Shutdown operation
Close the water source valve and power switch. ‌
Clean the internal and external contact surfaces of the equipment. ‌
Key points of maintenance and upkeep
1. Daily inspection
Check the drainage effect of the drain valve monthly and clean or replace it in a timely manner. ‌
Regularly check the function of the safety valve to ensure normal pressure control. ‌
2. Cleaning and maintenance
When scale is formed, chemical cleaning (such as sulfamic acid, ammonium difluoride, etc.) should be used. ‌
Cleaning solution ratio: Acidic cleaning agent concentration of 5%~10%, temperature of 60 ℃; Neutralizer concentration ranges from 0.5% to 1%. ‌
3. Consumables replacement
Replace consumables such as sodium ion exchange resin and filter cartridge every six months. ‌
Regularly clean the reverse osmosis membrane to extend its service life. ‌
4. Security protection
The equipment should be placed in a well ventilated area to avoid high temperature burns. ‌
Operators need to receive professional training and strictly comply with safety regulations.
