The contact python is a professional solution for transporting cold beverages from the cooling machine or cold room to the tower or tap, maintaining the temperature better along the run. It integrates product lines and cold water irrigation lines within an insulated bundle, which is why it is widely used in beer, wine, vermouth, cider, kombucha, soft drink and other tap-dispensed beverage installationskeg system.
The contact python, also known as irrigation python, is designed so that the beverage reaches the point of service in better thermal condition. To achieve this, the product lines run alongside recirculated cold water lines, all protected by external thermal insulation.
It is a common solution in bars, restaurants, brewpubs, beer halls, festivals, catering, trade fairs and any installation where there is some distance between the cooling equipment and the tap.
In this spec sheet we clearly distinguish the type of inner tube intended for cold water recirculation according to the number of products in the python:
| Python configuration | Cooling tube for water recirculation | Size | Note |
|---|---|---|---|
| 1- and 2-product python | Clear PVC tube | 7 x 10 mm | Common solution in compact configurations with few lines. |
| Python for 3 or more products | Poly 1/2" tube | 9.5 x 12.7 mm | Configuration used in higher-capacity pythons and more demanding technical runs. |
| Number of product tubes | Recommended insulation | Typical application |
|---|---|---|
| From 1 to 4 products | 13 mm insulation | Compact installations, bars with few lines and setups where a more contained system is desired. |
| 5 products or more | 19 mm insulation | Installations with higher thermal load, more lines or runs where it is advisable to reinforce the insulation. |
The insulation used in the technical variants provided is flexible closed-cell elastomeric foam, CFC-free and intended for the insulation and protection of pipes.
| Need | Indicative recommendation |
|---|---|
| 1 or 2 products | Compact python with irrigation lines in 7x10 mm clear PVC and insulation of 13 mmkeg system. |
| 3 or 4 products | Python with irrigation lines in Poly 1/2" (9.5 x 12.7 mm) and insulation of 13 mmkeg system. |
| 5 or more products | Python with irrigation lines in Poly 1/2" (9.5 x 12.7 mm) and insulation of 19 mmkeg system. |
| Long run or warm environment | It is advisable to review the chiller, the water recirculation, the insulation and the return accessories using sound technical criteria. |
To correctly complete the installation of the contact python, you will usually need the water return U and, depending on the type of setup, the appropriate fixing accessories. Here are the direct links:
In addition to the number of product lines, the type of water recirculation tube changes. In pythons for 1 and 2 products we use 7x10 mm clear PVC, while in pythons for 3 or more products we use Poly 1/2" tube (9.5x12.7 mm)keg system.
As a general rule in this spec sheet, 13 mm insulation is used in configurations of 4 products or fewer and 19 mm insulation in configurations of 5 products or morekeg system.
No. Unless expressly stated, the return U is not included. That’s why we’ve added to this page a block with links to the plastic U, the John Guest U and the recommended clamps.
Yes. The contact python is sold by the metre. The usual full coil is 50 metres.
No. Although it is a product widely used in beer installations, it can also be used for other beverages dispensed on tap that need to maintain temperature along the run.
At Install Beer we help you define the right configuration according to the number of products, distance, type of cooling, installation run and the accessories needed for water return.
