How to clean the scale in the water-cooled chiller?

1. Physical methods. This method is relatively simple. Generally, a high-pressure water gun is used to shoot the copper tube of the condenser and a brush is used to clean the accumulated scale inside, but this method may not be able to clean it completely;

2. Chemical methods. Water quality is also more important to the chiller (this point, Shenchuangyi Refrigeration will discuss this in another article), if the chiller was installed and the water source was discovered to be hard

Water, physical methods cannot clean the scale. At this time, a special chemical solvent and water can be used to immerse the copper tube on the inner wall of the condenser to clean up the scale. This method takes a long time and may have The possibility of corrosion of copper pipes;

3. Combination of substances. After mixing the special chemical solvent and water, pour it into the inner copper pipe and soak it for 2-3 hours (longer time is OK). After the soaking time is up, use a high-pressure water gun to spray the softened scale in the inner copper pipe, and then filter with water , And finally put in the prepared pre-filming agent, and the copper tube on the inner wall can be restored to the original metal.
