I want to purchase a 50' roll over copper tubing and found a good deal on some 1/2" refrigeration copper tubing. Is there an issue with usinbg this size?
It depends on the size of the batch and how cold of a water source your working with. With 50' of 1/2" refrigeration tubing I am able to bring a 5 gallon batch down to 75 degrees in about 15 minutes using a submersible pump in ice water circulating at 170 GPH.
