rticle copper corrosion of coils
It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

Article copper corrosion of coils
Found all this while searching for information about copper corrosion. 2 cases I have for the moment: 1 piece of +/- 15 cm (7 inch) Armaflex isolated 1 3/8 pipe of a Daikin VRV, installed underground but in a seamless PVC sleeve, no water in the sleeve and +/- 50 leaks on it.
Another case: 2 independent evaporators in a ventilated counter and +/- both have leaks on 1 piece of +/- 10 cm (+/- 5 inch) 1/2 tube, sometimes 100 leaks on this end.
No agresive cleaning agents used, only twice a year cleaned with drinkable water.It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

Re: rticle copper corrosion of coils
You can always blame Global Warming......
Seriously, I have seen galvanised steel pipes wrapped with PVC isolation tapes and was told that it prevents all kinds of external corrosion.
Maybe it worth trying.
