The BrewCommander™ Brewhouse Controller is a high precision, intuitive, complete brewhouse touchscreen controller for automatically ramping and maintaining the temperature of your boil kettle, mash tun, or hot liquor tank. With the Relay Module, you can control 2 heating elements in the same kettle for faster heating times. This pares perfectly with our 55 gallon Boilermaker™ G2 Kettles.
