5 years. Plus they have automatic makeup which would be adding more oxygen. There were several tubes that exhibited pin holes and there was corrosion throughout the pipes. Regardless this was a long term occurrence and not something sudden, which for my current scope is all I need. I assume you...
Typically steel in a brine solution is not a good mixture, but I am looking at a chiller that was installed for an ice rink and they used SA179 for the tubes in the chiller and a 21%CaCl2 solution. The refrigerant is R-717(ammonia). Is this as obvious of a mistake as I think it is?
Thanks
