Gas bottles for propane gas in caravans and motorhomes

What are gas tank cylinders? 

Gas tank bottles have a special, further developed safety valve with an 80% fill stop function that prevents the gas bottle from being overfilled.

This means that the gas tank bottle no longer has to be replaced like conventional 5 kg or 11 kg gas bottles, but can be refilled or topped up at any time - gas tank bottles can be refilled themselves.

For this reason, the gas tank bottle offers its user more flexibility and freedom - especially as a camping gas bottle, for barbecuing or as a tank bottle for permanent installation in a motorhome, camper van, CUV, boat or caravan

Gas tank bottles in the motor home are mounted in the gas box with a stable gas bottle holder on the rear wall of the gas box.

To enable refuelling with gas, an additional LPG filler neck for motorhomes is mounted on the outside of the body. Via the filler neck and in conjunction with the country adapter, the gas cylinders can be refuelled at any car gas filling station. 

The Alugas Travelmate goes mobile - New gas test

Standards and regulations adapt just as technology opens up new opportunities for users through constant further development: It just sometimes takes a little longer until everything has been tested and can be written down in regulations for publication.

Thanks to the removable collar of the aluminium gas tank cylinder, it has always been prepared for mobile transport.

Now the legislator is opening the door to making these cylinders - which are actually permanently installed in the vehicle - quickly removable again: without the need for tools.

A first step is the star grip kit we offer for retrofitting or initial installation!

 

 Sterngriff-Schraube

Simply loosen the star grips by hand and the bottle is released from its holder :

 

Brackets, adapters, hoses and star grips in our shop. Please be sure to take advantage of our advice at cara-tech-24.

 

As part of the changes to gas testing, retrofitting will also be necessary for existing installations from 2025!

 

Here, it is particularly important to check the filling side (from the flat refuelling adapter to the filling valve on the tank gas cylinder), as an emergency disconnection must be installed from this date at the latest.

You can find the necessary quick-release coupling here.

 

The quick-release coupling in combination with the star grips is not only required by the inspectors, but also has a very practical benefit for you.

From now on, you can quickly remove your tank gas cylinder from the gas tank without tools, e.g. to store the vehicle in closed buildings for the winter (often a requirement of the barn rental company!) or to carry it outside the vehicle for refuelling.

 

Alugas tank cylinder

One of the best-known refillable gas bottles is the aluminium gas bottle from Alugas. The Alugas Travel Mate cylinder is characterised by its high-quality workmanship and is one of the lightest LPG cylinders on the market. The aluminium gas bottle offers the advantage of a removable bottle collar for more convenient and space-saving installation, especially for fixed installation in the camper van gas box. The safety valve of the Alugas gas tank bottle has a mechanical gas level indicator so that the gas level can be read directly from the gas bottle. The mechanical indicator is not particularly precise and should be regarded as an indicator of whether the gas bottle is full, half empty or empty. 

The Alugas gas tank bottle is CE certified and is subject to a 10-year gas tank test by the TÜV.

CAMPKO composite gas tank cylinder

The CAMPKO composite gas tank bottle is available with OPD and multi-valve. Both valves have an 80% fill stop function.

The multi-valve version also has a mechanical gas level indicator and two separate connections for gas refuelling and gas withdrawal.

The composite gas tank bottle is the lightest gas bottle in terms of weight, but does not have a removable bottle collar. It is often used as a portable cylinder in the leisure or camper gas sector.

CAMPKO steel gas cylinder 

The steel gas tank bottle is a real heavyweight with its high safety standard.

The weight of the CAMPKO steel gas cylinder is on the one hand higher compared to aluminium gas or composite gas cylinders, but on the other hand it is the only one that meets the high ECE 67R-01 standard from the automotive sector.

Gas cylinders and motorhome gas tanks with ECE 67R-01 homologation are not subject to a 10-year inspection period by the TÜV and meet the highest safety standard. 

The bottle collar of the CAMPKO gas tank bottle is not only removable: The open construction of the bottle collar also offers enough space for the installation of a gas pressure regulator or a Drehmeister gas bottle filter when mounted. The CAMPKO gas tank bottle also has a mechanical gas level indicator on the valve and, due to its material, is compatible with all external gas level indicators from Rotarex, Mopeka, Gaslevel and GOK.

CONCLUSIONS:

If the weight of the tank bottle is not a decisive criterion, then the steel version is the best solution! It is economically superior in price to the composite and aluminium gas cylinders, offers the user a higher safety standard and does not have a 10-year inspection period. 

How much gas is in my gas cylinder?

The gas level in your gas cylinder can be measured with external gas level indicators. Possible solutions are the Rotarex Wave Box, Mopeka gas level indicators, the Classic series from Gaslevel and the GOK level indicator Senso4s.

 

Advantage of liquefied petroleum gas: high energy density in a small volume.


Liquid propane gas has a weight of about 509 g/l. This means that a full 5 kg propane bottle contains around 10 l of propane gas at an outside temperature of 15 °C. This means that an 11 kg bottle contains 22 l, and so on.
In an 11 kg bottle, there are 22 l, etc.
To liquefy the gas, it must be brought to a temperature of slightly below -42 °C. Alternatively, 8 bar overpressure compared to the outside temperature is sufficient. Alternatively, 8 bar overpressure compared to the atmosphere at ambient temperature is sufficient.
This is slightly more than the pressure in a bicycle racing tyre.
This enormous physical advantage over other gases is what has made the propane cylinder so successful worldwide:

In the process, the volume of propane is reduced approximately 260 times.

In the 5 kg gas bottle with 10 l of liquid gas, there are therefore approx. 2,600 l of propane gas.

In order to maintain this compression, a pressure vessel is required that can usually withstand a test pressure of 30 bar. All our gas cylinders exceed this requirement by far, come from certified manufacturers and provide safety in use for many years - regardless of whether it is for private barbecuing on the terrace or for commercial use in forklift traffic.

It is important to note that the liquid gas in the propane cylinder tends to expand even with minimal temperature increases.
To prevent the safety valve from being triggered immediately in summer, the propane cylinder is only filled to 80 %. This gives the gas enough room to expand. A 5 kg propane bottle with 10 l of liquid gas therefore has a volume of about 12 l.
