Built this jacketed fermenter using 8 meters of copper coil wrapped tight around a plastic 25 liter fermenter, then insulated it on the outside with about 3 inches of this foam. The copper coil is connected to the python pump on the maxi 310 cooler. Water temp in the cooler bath reads 1 centigrade, so i'm assuming that's the temperature it's being pumped out at, which should be ideal for cold crashing, but after 2 days of leaving it on only managed to get the beer temperature down to 9 centigrade.
Today I added a couple of layers more insulation, and the black insulation on the pipes, so will see how it goes tomorrow.. ideally i'd like to get the beer to about 4 centigrade for the cold crash.
Has anyone else got a jacketed fermenter to work effectively using a cooler like this?
