Keep It Cool: How to Prevent Warm Beer with Proper Glycol System Maintenance

When a glycol system malfunctions, it can result in warm beer from the tap.

No one wants to be served a warm beer when they’re expecting a cold, refreshing pint. If you’re a bar or restaurant owner, ensuring your draft beer is always perfectly chilled is crucial. One of the best ways to achieve this is by maintaining your glycol cooled draft beer system. At A Head for Profits, we specialize in beverage dispense equipment sales and installation, and we’re here to help you keep your draft beer system in top shape.

Understanding Glycol Cooled Draft Beer Systems

A glycol cooled draft beer system is designed to maintain your beer at the ideal temperature from keg to tap. This system uses a mixture of glycol and water to keep the beer lines cold, ensuring that every pour is perfectly chilled.
Propylene glycol, a non-toxic, food-grade antifreeze, is combined with water to create a chilled mixture that runs parallel to your beer lines. As the beer travels to the tap and is poured, the glycol lines keep the beer as cold as the temperature in the cooler. This setup is ideal for long draw systems, especially those running 25 feet or more.

Common Causes of Warm Beer

Several factors can cause your beer to be warmer than it should be. These include:
Improper Maintenance of the Glycol Chiller: Regular maintenance is key to ensuring your system runs smoothly.
Issues with Insulation or Glycol Lines: Poor insulation or leaks in the glycol lines can lead to temperature fluctuations.
Malfunctioning Components: Pumps, thermostats, and other components need to be in good working order.

Regular Maintenance Tips

To keep your glycol cooled draft beer system running smoothly, regular maintenance is essential. Here are some tips to make sure your system stays in top condition:
Check Glycol Levels and Concentration: Regularly check the glycol levels in your system and ensure the concentration is correct. A 35-40% glycol to water ratio is typically recommended. This helps prevent freezing and ensures efficient cooling.

Inspect Glycol Lines: Look for any leaks or insulation issues in the glycol lines. Proper insulation is key to maintaining the correct temperature.

Check Pumps and Thermostats: Make sure that all pumps and thermostats are working correctly. Faulty components can lead to temperature issues.

Monitor the Glycol Bath Temperature: Regularly check the temperature of your glycol bath to ensure it’s within the optimal range, typically 26-28 degrees Fahrenheit for alcoholic beverages.

Clean the Condenser: Check the condenser every few weeks and clean it as necessary to remove dirt and debris. This helps maintain efficient cooling by preventing clogs.

Troubleshooting Warm Beer Issues

If you notice that your beer is warmer than it should be, here are some troubleshooting steps:
Adjust Glycol Concentration: If the glycol concentration is off, adjust it to the recommended ratio.
Repair or Replace Faulty Components: Identify any faulty components and repair or replace them as needed.
Check the Trunk Line: Inspect the trunk line for any damage or ice buildup, which can indicate insulation problems or leaks.
Check the Faucet Temperature: Measure the temperature of the beer coming out of the faucet to check it matches the system settings.
