The BrewBuilt CoolStix is a revolutionary cooling solution for Fermonster and PET carboys. It is easy to clean, easy to setup, and cools quickly and efficiently. The CoolStix uses a submersible pump to circulate cooling solution and a digital temperature controller to regulate flow. When the controller's temperature probe detects that the fermentation temp is getting too hot, it will power on the submersible pump to run ice water or glycol through the CoolStix. Once the temperature stabilizes, the controller will shut off the pump and stop circulation.
This kit includes all the necessary hardware to set up and start using the CoolStix with a Fermonster or PET Carboy. It features a custom designed 3-hole silicone stopper (#10), specifically sized to fit the Carboy Carboy CoolStix, a thermowell, and an airlock (airlock not included).
