Ferment 20 gallon batches of beer in these beautiful conical fermenters, and control the temperature of your fermenting beer to within 1 degree, any time of the year! The included Dual-Stage Controller will simultaneously control both the cooling unit and the 40-Watt heater. The cooling units mount to the outside of the cone with no internal contact with the beer. The cooling is extremely gentle on your yeast, changing wort temperatures at about a degree an hour. It can get to and hold your ale fermentation temperatures of 65-72 Fahrenheit all the way up to ambient temps of 100 Fahrenheit. In addition, it can get to and hold lager fermentation temperatures of 48-52 Fahrenheit all the way up to ambient temperatures of 80 Fahrenheit. The Leg Extension Option (CONP769) is needed if you wish to gravity feed into a keg. If you would like to use CO2 to push your beer into a keg, you will need the CO2 Adapter Package (CONP775). The domed lid has it's own cover, made from our heavy-duty foam insulation, for better temperature control. Cooling is made to work with 20 to 22 gallon batches. Please note that when dropping temperature, your fermenting wort will contract and may pull liquid from your blowoff bucket into the fermenter. This may also occur when dumping trub from the bottom port, or when racking from the racking arm.
