Quality is an innovative, modular conical designed for you. The new CF Spike Conicals are pro quality tanks designed for the homebrewer. They're also all unitanks which means they can handle pressure up to 15psi. That allows you to carbonate in your fermenter without a separate brite tank or waiting days for your beer to ferment in kegs or bottles. These fermenters are scaled down versions of what you will see at any profession brewery. All sanitary welded tri-clamps, butterfly valves, 60° cone angle and dedicated tri-clamp for use with a blow off cane. If you are ready to step your fermentation game up to the best this is the product for you!
