1. Product Description

   Control your fermentation temperature accurately, every time!

   • 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 flavor profile. 
   • With the ability to individually power and control the temperature of up to four Grainfather GF30 Conical Fermenters, each with their own fermenting schedules, the Grainfather GC4 Glycol Chiller is the perfect addition to ensure superior fermenting results.

   Design:

   • With a sleek and compact design, that still accommodates our full array of features, the GC4 Glycol Chiller maintains the Grainfather’s principle of providing quality home brewing equipment, that delivers craft brewery like results, with a small footprint.
   • With the addition of the GC4 Glycol Chiller, your system is operating at the ultimate level and you are even able to cold crash and lager down to 4-6ºC (39-43°F). The GC4 Glycol Chiller connects to a hidden cooling sleeve, located in between the two stainless steel walls of the GF30 Conical Fermenter. Your desired temperature is dialed into the digital temperature controller on the GF30 Conical Fermenter, the liquid then travels through this sleeve, cooling the stainless steel which in turn cools the beer in the fermenter. The cooling sleeve never comes into contact with the beer, is completely concealed and does not need cleaning or sanitizing - a true innovation for a fermenter on this scale.

   Features:

   • Allows you to cold crash 23 L (6 US Gal) of wort to as low as 4-6ºC (39-43°F). Minimum temperature will vary based on external factors such as ambient room temperature, the number of fermenters connected and other environmental conditions.
   • Cools and powers up to 4 GF30 Conical Fermenters at different temperatures and fermenting schedules.
