your wort is flowing too fast. if you can slow down the wort and speed up the water that would help. turbulence in the water would help too.

Damn, it's a nice looking chiller but there's only 12 feet of contact ("turbulent" or not) between wort and water. My homemade rig is about 19 feet and my wort reaches water temp without taking 2 hrs :/

Yes, 12 feet is too short for 12 gal with 65F tap water.
I would suggest making post-chiller submerged in ice water, recirculate wort until it falls to 100F (at the end of CFC) and then pass it trough ice water.

I have 25 feet CFC and it takes 45-60 minutes to chill 10 gallons to 63F with 61F tap water.
Since I have HERMS, at my last batch I used HEX as post chiller- I filled it with ice and added water just to cover ice. I passed wort to HEX after it drops to 100F and it took ~20 minutes to run whole 10 gal batch cooled to 60F.

that chiller from morebeer should be plenty, just have to get the flow rates right; fast water and slow wort.

That's the problem though. Its almost a trickle to keep under 70 degrees. So it takes 2 hours to chill 12 gallons.

I use a plate chiller from Blichman with 68F water and the wort comes out at a reasonable clip at 71F. Probably took about 20 mn for 10.5 gallons last time I used it.

I recirc my wort back into the boil kettle on a immersion chiller and can get down to 68-69 in 25-35 minutes usually...(5 g batch)

wow. i thought the convoluted copper was maybe the same surface area as a longer chiller. at $180 i'd be on the horn with morebeer asking them where's the beef.
