THE THIRD IN OUR “FREQUENTLY ASKED QUESTION” SERIES TAKES US TO G&D CHILLERS. THEY GIVE US A LOOK INTO THE WORLD OF REFRIGERATION EQUIPMENT FOR THE DISTILLING ENVIRONMENT.
WHAT IS A CHILLER? A chiller is a versatile piece of central refrigeration equipment. Instead of cooling air like your refrigerator or air conditioner, it cools fluid which can then be pumped throughout an entire facility to provide cooling to any number of different processes: air conditioning, distillation columns, mash coolers, heat exchangers, fermentation tanks, etc.
WHAT IS GLYCOL? Much like antifreeze used in a car, it protects the chiller and process piping from freeze damage. Glycol is a heat

transfer fluid. It is cooled in the chiller, then pumped through the distillery, where it is used to cool many different processes. Some systems use glycol to cool water, and then the water is used to cool the equipment in a distillery.
DO I NEED GLYCOL? It depends on multiple factors: location of the chiller,
ambient conditions. If the chiller is located indoors and the operating temperature is high enough, you probably don’t need glycol. However, if the chiller is located outdoors, in almost all but the warmest climates, glycol is a necessity.
