Propylene Glycol


Propylene Glycol is used with water to create the cooling medium in Glycol Chillers. Adding glycol to the water lowers the water's freezing point, allowing the cooling medium to drop below freezing. This makes the cooling system more responsive to temperature changes in your storage vessels, and makes it possible to bring the wine down to cold stabilization temperatures as well as controlled fermentations.
