Should copper-based corrosion inhibitors be added to the circulating cooling water?
Thread Content
I’m seeking help from fellow forum users. My question is as follows: The ammonia content in the circulating cooling water in my system is within 10 ppm, and some of the heat exchanger tubes are made of copper alloy. I know that copper corrodes when it comes into contact with ammonia in the presence of water. In this case, does my device’s circulating water system need a copper corrosion inhibitor or a substance to prevent copper from corroding?
Adding ammonia is used to adjust the pH; a slight increase in pH can delay corrosion
Add as much as possible; once copper corrosion starts, it is very difficult to eliminate. If I had known there were copper components, why add so much ammonia?
We have some recycled water that contains a small amount of ammonia, which is mixed into the circulating water in very small quantities. Thank you very much for getting back to me
