Brewtools Unitanks are fermenters made for ambitious homebrewers and small breweries. Rather than an in-solution cooling apparatus, these tanks feature a cooling jacket in the vertical walls to offer efficient cooling without the hassle of cleaning a coil after every batch. Featuring their trademark PureBlast™ surface inside and out which eliminates the use of way and polishing compounds and doesn't require passivation. Designed and manufactured with special attention to safety and quality.
