Beer Trunk Line
If you have a long-draw draft beer system, the optimal solution for you would be using glycol-chilled beer lines, as opposed to the regular air-cooled lines used in direct-draw draft beer systems where the dispensing point is not far from the keg or walk-in cooler.
Since long-draw draft beer systems predominantly use glycol to chill the beer, in addition to the glycol chiller, you will also require another essential piece of equipment - beer trunkline.
BeverageCraft offers glycol beer trunk lines of various diameters and capacities guaranteed to suit your particular beer dispensing needs. Feel free to browse our selection by clicking on the items you’re interested in for more details, product images, and prices.

The Basics of a Glycol Draft Beer System
The true advantage of glycol-based draft beer systems is that they offer a fool-proof method of delivering beer at a specific temperature from the walk-in cooler and let you environmentally control it all the way.
In terms of range and capacity, glycol systems can go up to 750 feet long and have anywhere from 4 to 20 products dispensed at the same time, which makes them a great option for bars, restaurants, and hotels.
The three fundamental components of a glycol draft beer system:
- Power pack
- Beer tower
The power pack, which is essentially a commercial refrigeration unit, is the heart of the glycol system. Despite being quite compact in size, power packs can have from one to three motors and pumps able to manage up to three trunklines each up to 750 feet in length capable of handling up to 24 beer products each.
What Is a Trunkline?
An insulated beer trunk line is essentially a bunch of beer lines bound together with usually two or four glycol lines (depending on the number of beer lines) wrapped in a shield of foam and encased in a plastic waterproof jacket for insulation.
The trunkline provides a conduit of beer product lines connecting kegs or barrels in your walk-in cooler to each respective faucet of the draft beer tower while also housing sealed refrigeration lines from the power pack to the tower in a continuous loop.
Trunk lines are typically installed overhead or under the floor. If installed overhead, the exposed downward trunk lines would generally be housed in a combination of PVC tubing and a decorative finish.
When installing under concrete, these product lines would be run through a section of PVC tubing.
How Do Glycol Systems Work?
In a typical glycol system, the power pack pushes refrigeration through the center of the trunkline. The trunkline contains two lines:
- Outbound glycol line - runs from the power pack to the tower
- Return glycol line - enables the refrigerant to complete the cycle and become re-chilled
Therefore, the refrigerant lines are there to keep all of the surrounding beer lines temperature-controlled the keg or barrel to the point where they’re dispensed.
Beer Trunk Lines From BeverageCraft
