If there is a long-draw beer system in your bar, then you should definitely buy a trunk line. This is the kind of pipeline that connects the kegs in the kegerator with the corresponding tap of the beer tower.
When transporting beer from the refrigerator to the beer tower, it is important to ensure the beer stays cold. This function is performed by the main line, which contains sealed cooling lines from the power supply unit to the tower in the form of a continuous circuit.
Read our article to know what to pay attention to when choosing this equipment and where it is best to buy.
- Inner diameter
The longer the total run, the larger the diameter needs to be. There are 3 sizes available: 1/4, 3/8, or 5/16 inch.
Also note the smaller the diameter of the product line, the more restriction the line has (a higher pressure is needed to push the drink through the system).
- Foil wrap
Modern lines are equipped with single-layer pipes made of 100% primary polyethylene, wrapped with aluminum polypropylene film (foil), and covered with insulating, moisture-proof film and a barrier jacket.
The foil helps to direct the transfer of cold from glycol to beer, the insulation is responsible for maintaining the correct temperature of the drink, the moisture-proof film prevents the formation of condensate in the insulation, and the barrier jacket protects the insulation from damage.
- Number of beer lines
Depending on the number of beer types you are dispensing, you can choose from a trunk line with 2 to 8, or with 10 to 16 beer lines.
- Number of glycol lines
The quantity of glycol lines does not match the number of beer lines. For example, 2-8 product trunk lines have 2 glycol lines, while 10-16 product trunk lines are equipped with 4 glycol lines.
You can place the trunk line overhead or under the concrete in the floor.
If you choose to place this line over your head, it should be made of PVC tubes and covered with a decorative finish.
When placing a trunk line under concrete, it will pass through a section of PVC pipes.
