Draft beer trunk line is essential equipment for every beer dispensing system, where several beer taps are connected to a centralized cooling unit.
They are responsible for the supply of chilled glycol to the beer taps, ensuring the optimum temperature of the beer throughout the dispensing process.
That is why the beer trunk line is often used in commercial establishments like bars and restaurants, as well as in industrial breweries.
Keep reading our article for more information about all the features of the equipment, as well as where it can be purchased.
Glycol Trunk Lines: How To Improve Beer Dispensing
The main purpose of using the glycol trunk line is to preserve the quality, taste, freshness, and aroma of the draft beer.
The system works as follows: due to the pressure supplied from the gas cylinder, the beer is pushed out of the keg and comes to the point of its dispensing (beer dispenser with draft beer faucet) through the beer lines.
Since we are talking about the industrial scale of production, the kegs can be located far from the beer tower. Without using draft beer trunk line beer can get too warm due to the transfer of heat from the environment, which will worsen its taste, aroma, and appearance.
By circulating chilled glycol through an insulated beer trunk line, the beer is kept at the desired temperature from the barrel to the tap.
That’s how glycol trunk lines help maintain the ideal temperature for beer:
- Cooling mechanism
Cooling glycol circulates along the main lines. It absorbs heat from the beer lines, maintaining the beverage at a temperature of 36°F to 40°F, which is suitable for most beers.
- Temperature control
The main lines are connected to a glycol cooling system that includes a cooler and a temperature controller.
Insulated Beer Trunk Lines: Keeping Brews Cold and Fresh
Insulated beer trunk line allows to minimize heat flow and prevent temperature fluctuations.
Beer line insulation helps to maintain a constant temperature even in changing environmental conditions. Your product will always be fresh and chilled, no matter what the temperature in the room where it is stored and dispensed.
Choosing the Right Beer Line Size and Material
When choosing this equipment it is important to understand what size beer line for kegerator.
We have compiled a few recommendations that will help you choose the best tubing for beer lines. Let’s start with the material. Thus, the main glycol lines can be made of PVC, vinyl, stainless steel, silicone, and polyethylene.
Ensuring Optimal Performance: Beer Line Pipe Size
To calculate a suitable size you need:
- Determine the required flow rate. It depends on the type of beer and the desired dispensing temperature.
- Measure the vertical distance from the barrel to the tap. Also, measure the horizontal distance if the beer line has coils.
- Consider the diameter of the line: it affects the flow resistance. Usually, beer lines have diameters of 3/16″, 1/4″, and 3/8″. Smaller diameters create greater resistance, which may be suitable for shorter distances or higher dispensing temperatures. Larger diameters provide higher flow rates and are suitable for longer lines.
- Based on these data, you can use a resistance calculator that takes into account factors such as line length, diameter, height, temperature, and desired flow rate.
Commercial Aspect: Where and How to Acquire Glycol Trunk Lines
When buying the main lines, it is necessary to consider the material, diameter, and length of beer lines, and also the supplier of these goods in the USA.
It is important to choose a company known in the market for many years and with a good reputation, which is confirmed by the feedback of customers and professionals in the industry.
