A glycol cooled beer tower utilizes glycol to help regulate the temperature of the beer within the tower. This is done by connecting a glycol reservoir to a low-pressure pump. The pump receives the glycol from the reservoir and circulates it through the beer tower.
While the glycol is recirculated, it absorbs the heat from the beer, thus cooling it down. The cooled glycol then returns to the reservoir, gets re-chilled and is then ready to begin the cooling process again.
The glycol itself does not come into contact with the beer. Instead, it flows through a series of tubing and coil-shaped plates, ultimately cooling the beer as it passes through the tower. Along with the glycol circulation, many glycol cooled beer towers also utilize a fan or blower for additional air cooling.
This allows for even greater beer cooling capabilities. This system is beneficial to brewers as it helps them to maintain product consistency and allows them to offer customers a consistent and quality chilled beer experience.
What is a glycol chiller beer?
A glycol chiller beer is a beer dispense system that combines a chiller and a glycol solution in order to keep beer cold and at the correct serving temperature during tapping, serving and storage. The glycol chiller beer system is set up with a chiller outside of the bar or restaurant, connected to a cold plate.
This plate is installed inside of the bar or restaurant and is connected to the kegs. The glycol solution is circulated between the chiller and the cold plate in order to keep the beer as cold as possible.
This is essential to having a good quality, cold beer. Another benefit of the glycol chiller beer system is that it can also be used to cool multiple kegs at the same time, and even cooling more than one type of beer at the same time.
How does a beer line chiller work?
A beer line chiller is a device used to cool and maintain a cold temperature for beer that is being dispensed from a keg or bottle. The chiller works by running cold water or glycol through a chilled coil which is then connected to the beer line.
As beer flows through the beer line, it is cooled by the chilled coil. This allows a beer that is being dispensed to remain cold and at a steady temperature. As the beer passes through the coil, the cold water or glycol running through the coil absorbs the heat from the beer, cooling it before it’s served.
The cold liquid then runs back through the chiller, to be cooled and ready to be used again. This process can be repeated multiple times, allowing the beer to be kept at a consistent cold temperature.
How do you use a glycol chiller?
Using a glycol chiller is relatively simple and straightforward. Firstly, install the chiller in your desired location and make sure it is securely mounted. Once it is installed, secure the lines that feed into the chiller for the glycol and coolant.
Connect them to the appropriate tank and the outlet of the chiller. The coolant is usually a water and coolant mixture, such as antifreeze, but you can use glycol or any other coolant.
Next, plug the chiller into a power source and switch it on. Depending on the model of glycol chiller, it should automatically start cooling. To check, use a thermometer to measure the temperature of the glycol solution coming out of the outlet.
The temperature should be lower than the temperature of the solution going in. If it is not, check the thermostat settings on the chiller and adjust them accordingly.
Once you are satisfied with the temperature, you can start attaching the lines that feed into the glycol chiller. Secure them according to the manufacturer’s instructions, and then connect them to the appropriate tanks and outlets.
For best results, also secure them to the walls or other buildings in your facility to minimize vibration and potential leaks.
You are now ready to start using the glycol chiller. Open the taps to let the cool solution out, and then secure the taps. You may also want to adjust the thermostat settings on the glycol chiller to your desired temperature.
If the solution isn’t cooling enough, you may need to adjust the thermostat further.
Once your system is all up and running, you should monitor your glycol chiller regularly to make sure everything is functioning properly. Regular inspections should also be carried out and any necessary repairs performed in a timely manner.
This will help ensure your glycol chiller remains in top condition and provides your facility with consistently cool and effective glycol.
How do you cool beer lines?
The most effective way to cool beer lines is to install a glycol chiller system that utilizes chilled glycol. These systems are designed to maintain a constant temperature, usually between 36 and 38°F, along the entire length of your beer lines.
The chilled glycol is circulated through a heat exchanger integrated into the system and is then pumped through the beer line runs. These systems work best when combined with an air-cooled condensing unit to provide additional cooling capacity.
Additionally, thermal insulation should be applied to the lines to keep the chilled glycol temperature consistent, and line losses should be minimized using couplers or connectors with internal insulation.
Regular maintenance, such as cleaning the glycol chiller system and checking the glycol concentration, is also important to ensure proper functioning.
How do pubs keep beer cold?
Pubs keep beer cold usually by storing them in refrigerators and cooling systems. Most of the refrigeration systems in pubs are temperature controlled, so the beer is kept at a constant temperature and usually between 32-38 degrees Fahrenheit.
Refrigerators in pubs may use cooling systems that use Freon, ammonia, or self-contained refrigeration systems. These systems allow pubs to keep beer cold for long periods of time, ensuring that customers always have access to a cold beverage.
In addition, some pubs use cooling towers and refrigeration systems to maintain desired temperatures. Usually, cooling towers are placed outside the pub so that the cold air can circulate throughout the entire bar.
This helps to create an ideal environment to enjoy a cold beverage. Finally, some pubs have specialized cooling equipment that can be used to quickly cool beer down to temperatures near freezing. This helps to ensure that beers are always served at the perfect temperature.
What is the purpose of propylene glycol in beer?
The purpose of propylene glycol in beer is to help maintain the desired balance of flavor and aroma compounds in the finished beer. It can also act as a stabilizing agent, helping to protect against spoilage bacteria and other microflora, prevent oxidation, and retain the beer’s flavor and aroma characteristics for a longer period of time.
Propylene glycol also helps to impart a smooth, light body to beers and provides a smooth mouthfeel. Additionally, it can help reduce body and maltiness, promoting a cleaner finish.
How often should glycol be changed?
Glycol should be changed at least every two to three years, depending on how it’s used and how severe the climates are where it’s in use. If your system is used in extreme climates, you may need to change it more frequently.
For example, in climates with extreme heat, the heat can break down the glycol quicker, and it may need to be changed after 1-2 years. On the other hand, in colder climates, the glycol may last up to three years or longer.
Light commercial and residential applications may not require glycol changes as often as industrial or institutional applications. An ongoing maintenance plan and regular monitoring of system pressures and temperatures should help determine when a glycol change is necessary.
Corrosion inhibitors should be checked and possibly replaced more frequently, usually every year or 18 months, and the pH of the glycol solution should also be checked regularly. If the pH is out of the manufacturer’s recommended range, it’s time for some preventative maintenance and a glycol change.
How much glycol do you put in a chilled water system?
The amount of glycol you add to a chilled water system depends on several factors, such as outside air temperature in the area and the maximum fluid temperature allowed in the system. Generally, a mixture of 40 – 50% glycol and water is recommended.
The maximum amount of glycol in a chilled water system should never exceed 50%, as it may cause corrosion and scale. Before adding any antifreeze to the system, you should always consult the manufacturer’s recommendations for the specific system and local climate conditions.
It is also important to follow the relevant safety recommendations for handling and disposing of glycol.
What beer contains propylene glycol?
Which is an organic compound with a sweet taste and syrupy texture that is sometimes used in food production. It is most often used in light beers and some specialty beers, such as Corona Extra and Amstel Light, and has been found in some Budweiser, Coors Light, Molson, and Kirin Lights.
Propylene glycol is also used in some craft beers, including some from Third Wave Brewing Company and Kona Brewing Company. Propylene glycol can be added as part of the brewing process, as a preservative, or a flavor enhancer.
It’s important to check the ingredients of any beer you’re drinking to make sure it doesn’t contain propylene glycol if it is not something you wish to consume.
What is PG in brewing?
PG, or propylene glycol, is a chemical used in the brewing process to reduce and adjust the flavor elements of a beer or other alcoholic beverage. PG is a colorless and tasteless substance that functions as a flavor enhancer and aids in foam stability.
In addition to its role in the brewing process, PG is used as an anti-bacterial, preservative, and sweetener. PG can be used in place of sugar to provide a lighter, crisper flavor and reduced calories in beer.
The substance also helps to create a longer shelf-life, allowing brewers to create larger batches that can last longer without spoiling. Propylene glycol also helps dissolve hop oil better, and provides a smoother mouthfeel with improved foam retention and better drinkability.
How big of a glycol chiller do I need?
The size of glycol chiller you need will depend on a variety of factors, including the type and size of your cooling system, the volume of your process water, and the ambient air temperature. Generally speaking, the higher the ambient air temperature, the larger the glycol chiller you will need.
before selecting and purchasing a glycol chiller, you should carefully measure and calculate all of your cooling process parameters. These may include pool volume, desired cooling rate, total dynamic head and cooling water flow rate.
Additionally, it’s also essential to consider control requirements, dimensions, and installation location. Once all of this is customized to your cooling needs, you can determine the proper size glycol chiller for your application.
