Insidebeer.com: All You Need to Know About Beer Trunk Lines
When it comes to dispensing draft beer, one of the essential components of a glycol-based system is the beer trunk line. A trunk line is essentially a bundle of beer lines that are insulated and wrapped around with glycol lines. These lines are designed to maintain the temperature of the beer from the walk-in cooler to the draft beer tower. In this article, we will explore the basics of beer trunk lines and how they work.
What is a Beer Trunk Line?
A beer trunk line is a set of beer lines that are bundled together with one or more glycol lines. The purpose of the glycol lines is to keep the beer chilled as it travels from the walk-in cooler to the beer tower. The trunk line is usually wrapped with insulation to prevent any temperature fluctuations. It is important to note that trunk lines come in different sizes and configurations, depending on the number of products and the inside diameter of the line.
Types of Beer Trunk Lines
Beer trunk lines come in different types, depending on the inside diameter, the number of product lines, and the type of coating. Here are some of the common types of beer trunk lines:
- Inside Diameter:
- 1/4" inch inside diameter trunkline
- 3/8 inch inside diameter trunkline
- 5/16 inch inside diameter trunkline
- The number of Product Lines:
- 2 to 8 products trunkline (features 2 glycol lines)
- 10 to 16 products trunkline (features 4 glycol lines)
- Taped jacket. Our trunk lines feature mono-layer, 100% virgin PE tubing, aluminized PP film wrap, and insulation.
- Extruded jacket
How Beer Trunk Lines Work
In a glycol-based draft beer system, the trunk line is responsible for transporting the beer from the keg or barrel in the walk-in cooler to the beer tower. The glycol lines wrapped around the beer lines provide a cooling effect, which helps to maintain the temperature of the beer. The glycol lines are connected to a power pack, which is essentially a commercial refrigeration unit. The power pack circulates the glycol through the trunk line and back to the power pack in a continuous loop, maintaining the temperature of the beer along the way.
Installing Beer Trunk Lines
When installing beer trunk lines, there are two options: overhead or under the floor. If installed overhead, the trunk lines would generally be housed in a combination of PVC tubing and a decorative finish. When installed under concrete, the product lines would be run through a section of PVC tubing.
Beer trunk lines play a critical role in ensuring that draft beer is dispensed at the correct temperature. There are different types of beer trunk lines available, depending on the inside diameter, the number of product lines, and the type of coating. When installing beer trunk lines, it is important to choose the right type and size for your draft beer dispensing system. By understanding the basics of beer trunk lines and how they work, you can ensure that your draft beer is always served at the perfect temperature.
