The Lupulus II 16-product beer trunk line brings a broad draft selection from refrigerated keg storage to the serving area through one insulated assembly. It contains sixteen 5/16" I.D. Lupulus II multilayer barrier product tubes and four 3/8" I.D. glycol circulation tubes.
For bars and taprooms offering a wide range of beers, barrier tubing helps protect each product’s flavour and aroma along the dispensing route. Its low gas permeability and low flavour migration support beverage quality, while the glycol circuit helps maintain serving temperature outside the walk-in cooler.
Built for Multi-Product Draft Systems
Sixteen separate beverage lines accommodate an extensive tap selection without running individual insulated hoses for every product. Colour stripes and printed identifiers help installers map the keg connections to the correct faucets and trace individual lines during cleaning or service.
The cooling circuit includes two blue glycol supply tubes and two red return tubes. These circulate coolant through the bundle alongside the product lines, carrying absorbed heat back to the glycol power pack.
Insulation and Taped Jacket
A 19 mm insulation layer surrounds the tubing assembly to help limit heat gain along the run. Aluminium foil and cling wrap enclose the internal bundle, with black PVC tape providing the outer protective covering.
Plan enough space for the trunk and its bends, and use supports that do not compress the insulation. Connections at the cooler and dispensing tower also need to be insulated and sealed to avoid leaving warm sections in the system.
Key Benefits
- Capacity for sixteen products: Suits bars, restaurants and taprooms with a large draft selection.
- Lupulus II barrier tubing: Helps protect beverage flavour and aroma through low flavour migration and low gas permeability.
- Smooth inner surface: Helps limit deposits inside the product tubes alongside regular draft line cleaning.
- Four glycol circulation tubes: Two supply and two return lines provide the coolant path through the bundle.
- 19 mm insulation: Helps reduce heat gain between refrigerated storage and the dispensing point.
- Individual line identification: Colour stripes and printed markings help technicians connect and service the correct product line.
- Taped outer covering: Black PVC tape protects the insulated assembly during handling and installation.

Selecting the Right Trunk Line
This model is intended for installations requiring sixteen product lines with 5/16" I.D. barrier tubing. Confirm the beverage line resistance, total route length, vertical lift and dispensing pressure before choosing the configuration. The glycol power pack and circulation equipment must also be sized for the complete installation.
