Copper manifolds wont prevent condensation in the tank unless it is before the tank with auto drains like our coolers are.
I would be curious to see a copper manifold setup before the tank and see what the inlet / outlet temps are.
I’m extremely happy so far with my cooler pulling 200° before it gets to the tank. Compressor kicked on about 5 times yesterday while I was fooling around with the new table and I didn’t have a drop of water in the tank when I was done.
