Exam Focus
- Explain types of cooling systems as a service topic within Draft systems.
- Use specific evidence such as temperature, pressure, package condition, sanitation, equipment state, and observed service symptoms.
- Apply the topic to beer flavor, dispense quality, safety, and guest experience rather than repeating the heading alone.
Core knowledge
- Direct-draw systems keep kegs near the faucet and minimize line length and heat gain.
- Glycol-cooled long-draw systems use chilled glycol beside beer lines and require attention to trunk routing, tower cooling, and pump performance.
- Air-cooled systems move cold air through ducts and are more sensitive to distance, air leaks, and uneven cooling.
Study application
Compare cooling types by layout, line length, heat gain risk, troubleshooting path, and service volume.
