BrewJacket
This control board upgrades your original cooling-only BrewJacket Immersion into a dual heating / cooling Immersion Pro or simply replaces your Immersion Pro control board. The upgrade process is easy, just unscrew the four screws on the top of your current Immersion head unit, lift off the control board and unplug it. To install the new Immersion Pro board, just plug it into the base and screw it in.
Rod sleeves are required for all low pH fermentations, including wine, cider, mead, sours, and kombucha.
Sanitizing with Star-San also requires rod sleeves.
