Ss Brewtech Home Brewing Chronical Fermenter; Stainless Steel (7 Gallon) CONICAL FERMENTER: Walk into any craft brewery, and youll find them filled with stainless conical fermenters. When we designed the Chronical, we wanted to give every home brewer the same quality tanks used by pros. DUAL FERMENTATION: The bottom dump valve allows you to harvest yeast and reduces yeast contact with the beer, allowing for a primary and secondary fermentation inside the same vessel. TEMPERATURE CONTROL: The Fermentation Temperature Stabilization System (FTSs) uses a precision temperature controller that constantly monitors the temperature of your fermentation to within 1 of its set point. PROFESSIONAL BREWING: Our Chronical fermenter is designed with pro brewing geometry in mind and features a rotatable racking arm, etched volume markings, a domed lid with secure spring clamps and an integrated PRV. SS BREWTECH: Since our launch in 2013, our mission has been to invent, not just innovate, high quality brewing equipment and accessories for brewers all over the world. At Ss Brewtech our passion is making good beer and designing cool brewing Sstuff.
