It’s designed to regulate and stabilize the fermentation temperature by pumping cold water through the double walled insulated interior. And in just one fell swoop, you can target the perfect temperature for better beer!
Cool your wort by simply connecting the couplets and insulated hoses to the Grainfather Conical Fermenter, submerge the pump into the cooler box with water (add ice for required temperature) and pump the water through the insulated cooling sleeve.
Control fermentation by setting the target temperature on the Digital Controller. Once the temperature is below the target temperature of the wort, the Cooling Pump will instantly pump cold water through cooling sleeve to cool down your wort.

This solution (pump/hot and cold hoses/and wiring) made possible the pumping of ice water through the conical fermenter perfectly during two to three day cold crashes while maintaining 38 degrees Fahrenheit in a 58 degrees Fahrenheit wine cellar. So far, used for three separate fermentations during the COVID quarantine. Not ready to take the glycol chiller plunge, this is a cost effective alternative.
