Does a weak salt-water solution corrode copper tube
(OP)
Dear all,
I have refrigeration system where the evaporator is copper tube in a bath. Now I need to use salt-water solution to refrigerate another storage place a bit below 0 degree Celsius may be -1 degree Celsius. I am planning to immerse the copper evaporator in salt water and circulate this fluid to the target but I afraid if the salt solution may corrode the copper evaporator.
So please let me know if weak salt solution may corrode copper tube and if so what else can i use as fluid

While Cu has fairly good corrosion resistance there is a high likelihood that you would get attack at any water/air interface.

Anyways thank you EdStainless, alcohol is a good choice for me it is available. but if you mention some non chloride salt for me that would be nice and one last question could sugar serve the purpose of salt?

Corrosion under deposits is far worse than just in wet locations.

There corrosion inhibitors in it are designed for mixed metallurgy systems.
