Glycol chillers are a specific kind of refrigeration system, often used to cool a variety of liquids including alcohol and other beverages. Using a chiller allows producers to rapidly drop the temperature of the product dramatically before carbonation or over a short period of time, depending on the production needs. Propylene glycol plays a significant role in the application of a glycol chiller. For cooling in brewing, there are few processes where decreasing or maintaining temperature are important like crash cooling a beer after fermentation, or keeping a steady temperature during fermentation (which generates heat), or cooling the wort after an initial boiling process. Glycol Cooled draft beer dispensing systems are typically used in commercial applications such as bars, restaurants. These systems use a secondary refrigeration unit (called a power pack or glycol chiller) to maintain draft beer at the proper temperature all the way from the walk-in cooler to the point of dispense. This is done by the power pack chilling and constantly circulating a water and a food grade anti-freeze (glycol) solution next to the beer tubing all the way from the walk-in cooler to the point of dispense. The tubing used is called trunkline or also known as python. In it the beer and coolant tubing are wrapped with a plastic moisture barrier, a foil wrap to transfer cooling, closed cell insulation, and some type of outside jacket to protect the insulation. A glycol bath can maintain a consistent product temperature, however it can not additionally cool the beer if the walk-in temperature is too warm. This system is great for longer distances, up to 500 feet. Multiple dispense stations can be linked to one system.
