The evaporator is about 25 feet of 3/8 copper, you will need to be able to remove the refrigerant from the system to weld in the new coil. In the article in the magazine he used the factory coil. I used 50 feet of 3/8 copper around the sanke keg as tight as I could get it. I am using a 250 gph pond pump to circulate the glycol around the keg. I used regular RV antifreeze (potable) for the glycol. I hope this helps you can PM me if you have any other questions
Awesome. Thank you for the info. I don't think I'll be able to remove the refrigerant so I think I'll just stick with the factory evap. I was also thinking about using multiple temp controllers so maybe in the (distant) future, I could have multiple fermenters cooling off one glycol bath.
Let us know how the beer turns out.
