What is the function of power packs in long draw draft systems?

• A. To heat the beer
• B. To cool and recirculate glycol
• C. To dispense beer
• D. To clean the beer lines

Answer: (B)

Power packs in long draw draft systems primarily function to cool and recirculate glycol. In these systems, glycol is used as a coolant that helps maintain the ideal serving temperature of the beer as it travels from the keg to the tap. The power pack typically includes a glycol chiller and a pump, which work together to circulate the glycol through insulated lines that run alongside the beer lines. This setup ensures that the beer remains cold throughout the dispensing process, which is crucial for preserving its taste and quality. Glycol systems are particularly important in long draw setups because the distance between the keg and the tap can lead to temperature increases that may negatively impact the beer. By continuously recirculating chilled glycol, the power pack effectively maintains a steady temperature, leading to a better overall drinking experience.
