I hope this helps!
Wonder why the question on the condenser coil? I have never seen a condenser coil fail in all my years of service except from outside forces. Mechanical, chemical, or environmental. And those are usually exempt from warranty. Now evaporator coils are a different story. Airborne food and cleaner acids eat coils. Expansion and contraction from the cooling cycles make things move and cause wear at mount and support points. Especially the old curved evaporators.
Oooooooooooooooooooooooooh. I hate those white painted delfield evap coils, I have 10 or so of these and 8 of them have leaked...........
Now they started painting them black, I guess they might have changed the epoxy or whatever they put on them? Happen to know what they changed? I am curious.
Condenser coil was the question. And yes, evaporator coils are going to leak eventually. They have to expand and contract with every on/off cycle. They are in a high moisture conductive environment. Makes for rubbing in mounts and end plates. Also ice build up has great pressure and can move anything. How many times have you found a return line with the nut on top and the line inside it crushed due to condensate laying in the nut and line freezing. Eventually pulling the flare out and leaking.
As for epoxy coatings, they are made for acidic or abrasive environments. Like open tomatoes, lemons, and limes. They like to eat copper, and worst copper connected to aluminum or steel. There are also some cleaning agents that some kitchens use that are very corrosive to coolers. The worst are the sandwich and pizza prep coolers. I've seen pizza shops that have a stainless pail of sauce in the cooler open and wonder why the copper coils of the evaporator have failed and full of pin holes.. .
