The Caramatic BasicTwo is designed as a two-cylinder system to supply gas equipment connected in the caravan or motor caravan from two gas cylinders. Nevertheless, the question arises again and again whether this two-cylinder system can also be operated with only one gas cylinder. The short answer is: Yes! But there are certain things you must consider.
Withdrawal from two gas cylinders, convenience thanks to automatic switching, simple installation, use in caravans or motor caravans as well as on boats – all this describes the Caramatic BasicTwo two-cylinder system. However: Is it possible to operate a two-cylinder system with only one LPG cylinder? We have the answer.
Normally, campers or captains use the Caramatic BasicTwo with two gas cylinders – one for operation, one for reserve. This ensures a secure supply of energy, even on longer trips.
The BasicTwo consists of a central and a changeover regulator. During installation, the specialist screws these two regulators to a gas cylinder and establishes a connection between the central and changeover regulators using a gas hose.
Another gas hose connects the outlet connector of the central regulator to the piping of the LPG system and ultimately to the connected gas equipment. A detailed description of the function can be found in this article:
To answer the original question, the replacement of a gas cylinder on the Caramatic provides an important clue. Because: The operator can replace the empty cylinder without interrupting the gas supply.
This function is actually nothing other than the operation of the two-cylinder system with only one gas cylinder – but for a short period of time. If you want to operate the Caramatic BasicTwo with just one gas cylinder for a longer period of time, you still have to consider a few things.
Although the latter is still attached to the system due to the connecting hose between the central and changeover regulator, gas cannot escape thanks to the non-return gas valve. This also prevents the outflow of propane or butane during cylinder replacement.
In conclusion: If you want, you can also operate the Caramatic BasicTwo two-cylinder system with only one LPG cylinder. However, the user should follow the procedure described above.
In principle, however, you should already think about the expected use before buying. If the camper or captain wants to permanently connect only one cylinder, the Caramatic is actually not the right product. If one cylinder is sufficient, then it would be sensible to use only a pressure regulator together with a gas hose.
