The Cooling Pump Kit allows users of the Grainfather Conical Fermenter to control the fermentation temperature with cold water by pumping it through the double walled insulated interior.

Temperature control is one of the most crucial elements for producing a good quality beer. It needs to be regulated and stable throughout the whole fermentation process to ensure the yeast doesn't get stressed and ferments correctly to get the right flavour profile.

To be able to cool with the Grainfather Conical Fermenter, you need to have the Conical Fermenter Temperature Controller. Then once your target temperature is below the temperature of the wort in your fermenter the Cooling Pump Kit pumps ice cold water through the double walled insulated interior to cool down your wort. 

Simply connect the couplers and insulated hoses to the Conical Fermenter, submerge the submersible pump into a cooler box with water (add ice for your required temperature) and pump the liquid through the insulated cooling sleeve of the Conical Fermenter body.
