What psi is optimal for glycol chilled systems?

The optimal psi for glycol chilled systems is typically in the range of 12-14 psi. This pressure ensures that the glycol is efficiently circulated through the system while maintaining adequate flow and temperature control. At this pressure, the fluid can effectively absorb heat from the beer, providing refrigeration without causing excessive strain on the system components.

Additionally, operating within this range generally allows for good thermal transfer efficiency, helping to stabilize temperatures in the beverage lines and in the serving kegs. Lower pressures may lead to insufficient circulation, resulting in inadequate cooling, while higher pressures can increase the risk of leaks or damage to system components. Therefore, 12-14 psi is considered a balanced approach for effective and reliable operation of glycol chilled systems.
