Valpar Industrial Limited was the first company in theworld to produce machine-made python, an insulatedbundle of tubing for draught drinks dispense. Todaypython plays a vital role in delivering high qualitydrinks at consistent low temperature. But optimumperformance requires python design to complementyour total dispense system. This is where Valpar canhelp you.

The Role of PythonToday the distance between cooler and point ofdispense can range from 5 metres - 100 metres andsometimes even more. The role of a python is tominimise the heat gain of a beverage after it leaves thecooler up to the point of dispense. Cold rooms andcoolers are all designed to take heat out of a beverageand the associated investment is relatively high. Howcan you ensure that this investment is not lost?

Return on InvestmentA well-designed and manufactured python willminimise the heat gain between cooler and tap thus,allowing the cooler to operate at its most efficientsetting.

This will reduce the workload and energy drain onyour cooler, leading to lower maintenance costs andextending its lifespan.

The day to day running cost of the entire coolingsystem will be reduced.

Last, but not least, your cooling system will be able todispense a greater number of colder drinks.

The Impact of Insulation Thickness in a Python

The industry standard choices of insulation thicknessfor pythons are 13mm and 19mm. For specialapplications, such as very high ambient temperaturesand humidity conditions, 25mm and 32mm insulationcan be supplied.

The two main issues to be considered when selectinginsulation thickness are heat gain and condensationcontrol.

The amount of heat gain entering a python can becontrolled by the insulation thickness. Heat gain canbe measured in Watts per metre. For example, theheat gain for 13mm insulation is 25% more than thatof 19mm insulation.

Sufficient insulation must also be applied to preventcondensation on the python's surface. For example, inan ambient temperature of 25oC a typical python with13mm insulation, and line temperature of 2oC, willgive condensation protection up to 70% relativehumidity whereas for 80% humidity 19mm insulationis required.

Valpar can assist you in the selection of insulationthickness for any particular application.

Python PERFORMANCE BY DESIGN

New in 2001A new super-smooth jacket has been developed tomake installation even easier, particularly where twopythons are being installed side by side.

As with standard taped python, we can help you topick the most suitable tubing and insulationspecifications for your draught applications.

Jacket python production is subject to minimumproduction run quantities. For further informationcontact a member of the Sales Team.

Non-insulated BundlesValpar non-insulated bundles are produced to meetsoft drinks industry needs. Soft drinks tubes are heldtightly in configuration by a food approved bundlewrap. This bundle is then covered with a tough jacket.Non-insulated bundles are

• ideal for use in Cold Plate soft drinks systems

• made to your specification using product lines from Valpar's wide range of soft drinks tubing.

The jacket on the bundle can be coloured to meetyour requirements.

Non-insulated bundle production is subject tominimum production run quantities. For furtherinformation contact a member of the Sales Team.

Cabled Pythons and BundlesIn response to your requests for more flexible pythonand bundles, Valpar now offers the option of cabledpython and non-insulated bundles. The lines aretwisted to give the product a greater degree offlexibility. This means it is easier to install in ductingand tight radius bends.

Twisted lines with insulation (cabled python) can betaped or jacketed. Twisted lines without insulation(cabled bundle) can also be taped or jacketed.

AccessoriesValpar can supply you with a range of accessories toaid python installation. These include tube andpython cutters, python pullers, python clamps,trunking, finger insulation, fittings etc.

Standard Insulated TapedPythonValpar standard insulated tapedpython is used by breweries andsoft drinks companiesthroughout the world.

Tubing ChoiceThe python is composed of acluster of product lines, whichare carefully positioned aroundwater or glycol recirculation linesto give optimum coolingefficiency. The water/glycolrecirculation lines are designedto take heat out of the productlines. We can help you tochoose the most appropriatetube for your particular draughtapplications - beer, soft drinks,spirits etc. The lines are heldtightly in configuration by theapplication of food approvedbundle wrap.

InsulationThe outside of the wrappedtubing cluster is then covered byflexible closed-cell foaminsulation. The low thermalconductivity of the insulationreduces heat absorption fromthe surrounding ambienttemperature. We can help youto select the most suitable sizeof insulation to deliver optimumperformance.

A PVC tape wrapping protectsthe insulation. Valpar insulatedtaped python is available in awide range of specifications andcan be manufactured to meetyour individual requirements.

The combination of insulationand the cooling recirculationlines help to ensure that thebeverage is dispensed at thecorrect temperature.

High-performanceInsulated Jacket PythonLaunched in 1999 in response toyour needs to dispense colderdrinks and optimise coolerperformance, there are nowover 2 million metres of high-performance insulated jacketpython installed worldwide.

Proven BenefitsThe jacket python is similar inconstruction to the standardtaped python. However, theouter jacket offers you anumber of proven benefits:

• The jacket ensures no compression of insulation, giving 15% (minimum) extra insulation performance, compared to the equivalent Valpar taped product. This in turn offers 15% reduction in load on the cooler. Your coolers will function more efficiently and use less energy.

• The python is not constrained by tape wrapping and offers greater flexibility for bending.

• The tough outer skin is highly tear-resistant which means that the insulation is better protected both during and after installation.

• "Snags" caused by tape overlaps are eliminated and python is easier to pull, thus reducing installation times.

• When making connections offthe python, jacket can be removed without shredding the insulation.

These are minimum benefits -some of you have told us thatyou have obtained even betterresults in the field and inindependent testing.
