The Art of Keg Cooling

Kegerators have become a popular choice for businesses and individuals who want to enjoy draft at the perfect temperature. These cooling systems are designed to not only chill the beer but also maintain its freshness and quality. In this article, we will explore the keg cooling system in detail, focusing on how it works and why it is essential for an optimal drinking experience.

The keg cooling system primarily consists of a refrigeration unit and a draft tower. The refrigeration unit, usually located at the bottom of the kegerator, is responsible for cooling the beer to the desired temperature. It uses a compressor and a coolant to lower the temperature inside the kegerator. This ensures that the beer remains cold and refreshing, ready to be dispensed at any time.

To assist in chilling the beer, the cold air from the refrigeration unit is directed upwards to the draft tower. This is where a tower cooler or fan comes into play. These devices help push the cold air upwards, ensuring that the beer in the tower remains chilled. Without proper airflow, the beer in the tower could become warm, resulting in a less enjoyable drinking experience.

It is crucial to set the kegerator to the appropriate temperature range of 34-40 degrees Fahrenheit (1-4 degrees Celsius). This temperature range ensures that the beer is kept cold without freezing it. Serving beer at the right temperature enhances its flavor, aroma, and overall drinking experience. It is also important to note that different beer styles may have specific temperature requirements, so it is advisable to consult the brewery's recommendations for optimal serving temperatures.

Kegerators come in various sizes and styles to cater to different needs and preferences. There are indoor kegerators designed for home use, which can be placed in kitchens, basements, or man caves. Outdoor kegerators, on the other hand, are built to withstand different weather conditions, making them ideal for patio or backyard installations. Some kegerators even come with additional features like built-in taps, digital temperature controls, and multiple keg capacity, providing convenience and versatility to users.

Businesses such as bars, restaurants, and breweries greatly benefit from kegerators as they allow for efficient and consistent beer dispensing. With a keg cooling system in place, establishments can serve draft beer at the perfect temperature, ensuring customer satisfaction and repeat business.

The keg cooling system is an essential component of a kegerator. It ensures that the beer remains cold and refreshing, enhancing its flavor and overall drinking experience. By setting the kegerator to the appropriate temperature range and utilizing a tower cooler or fan, businesses and individuals can enjoy draft beer at its best. So, whether you are a beer enthusiast or a business owner, investing in a kegerator with a reliable keg cooling system is definitely worth considering.

How Are Kegs Cooled?

Kegs are cooled in various ways, but one common method is using a refrigeration unit. The refrigeration unit is typically located below or behind the bar counter. It cools the keg by circulating cold air around it. Here's a step-by-step explanation of how kegs are cooled:

1. Refrigeration Unit: A refrigeration unit, also known as a keg cooler or beer cooler, is used to cool the kegs. This unit is specifically designed to maintain a cold temperature suitable for beer storage.

2. Cold Air Circulation: The refrigeration unit generates cold air, which is then circulated around the keg. This cold air helps to lower the temperature of the beer inside the keg.

3. Draft Tower: The draft tower is the vertical column on top of the bar counter from which beer is dispensed. The keg is typically connected to the draft tower via a beer line.

4. Cold Air Travel: The cold air from the refrigeration unit travels up to the draft tower to assist in chilling the beer. It helps to maintain the desired temperature of the beer from the keg to the point of dispensing.

5. Tower Cooler or Fan: In some cases, a tower cooler or fan may be installed to further enhance the cooling process. These additional devices help push the cold air upwards, ensuring that the beer remains chilled throughout the dispensing process.

Kegs are cooled using a refrigeration unit that circulates cold air around the keg. The cold air travels from the refrigeration unit up to the draft tower, where beer is dispensed. Additional cooling devices like tower coolers or fans can be used to assist in the upward movement of cold air. This ensures that the beer remains chilled and refreshing when served.

What Is A Keg Cooler Called?

A keg cooler is commonly referred to as a kegerator. Kegerators are specially designed refrigeration units that are used to store and dispense kegs of draft beer. They are built with a cooling system that keeps the beer chilled at the optimal serving temperature. Kegerators are equipped with a tap or faucet on the front, allowing users to easily pour beer directly from the keg. These units are typically used in bars, restaurants, breweries, and even homes for personal use. Kegerators come in various sizes and styles, catering to different needs and preferences. Some kegerators are designed for indoor use, while others are specifically built for outdoor settings. They can be freestanding or built-in, and may have additional features such as digital temperature control, stainless steel construction, and multiple tap options. kegerators are essential equipment for businesses and beer enthusiasts who want to enjoy the convenience and freshness of draft beer at any time. Some popular brands that manufacture kegerators include Edgestar, Kegco, and Nostalgia.


The keg cooling system is an essential component in the operation of kegerators. It plays a crucial role in maintaining the optimal temperature for serving draft beer. By utilizing a refrigeration unit, cold air is circulated throughout the kegerator, ensuring that the keg remains chilled between 34-40 degrees Fahrenheit.

To further enhance the cooling process, a tower cooler or fan can be utilized to push the cold air upwards towards the draft tower. This helps to prevent any warm air from entering the system, ensuring that the beer is dispensed at the desired temperature.

Kegerators are widely used in various businesses, such as bars, restaurants, and even homes, to provide a convenient and efficient way to serve draft beer. With different sizes and styles available, there is a kegerator to suit every need, including both indoor and outdoor options.

The keg cooling system is a crucial aspect of any kegerator setup. By maintaining the ideal temperature range and utilizing additional cooling methods, businesses and individuals can ensure that their draft beer is consistently chilled and ready to be enjoyed by customers and guests.
