Advanced Cicerone® · Keeping and Serving Beer

Types of cooling systems

Syllabus Path

Direct-draw systems keep kegs near the faucet and minimize line length and heat gain. Compare cooling types by layout, line length, heat gain risk, troubleshooting path, and service volume.

  1. I. Keeping and Serving Beer
  2. E. Draft systems
  3. 2. Types of cooling systems

Exam Focus

  • Explain types of cooling systems as a service topic within Draft systems.
  • Compare direct-draw refrigeration, forced-air long draw, glycol-cooled trunk lines, and temporary-system cooling at each heat-gain point.
  • Choose a cooling design and troubleshooting check based on run length, service volume, ambient heat, condensation, and temperature at the faucet.

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.
