Glycol Cooling Fundamentals

How can you maintain cool conditions?


Convection, Capacity, Glycol, Cooling, Conduction, Flow


Cooling in a modern brewery is generally provided by glycol whereas in older breweries ammonia was the refrigerant of choice. Its use is now very uncommon due to the significant safety risks associated with it. Therefore this lecture focuses on the basic concepts and practicalities of glycol cooling in the brewery.

Learning Objectives

  • Describe what glycol is
  • Explain how refrigeration works
  • Describe the heat transfer principles for glycol cooling in a brewery
  • Describe the uses of glycol in a brewery and the key design considerations
  • Calculate the required cooling capacity for a brewery
