A known problem for campers: The gas cylinders are empty rather quickly and the replacement process is cumbersome and eats into your leisure time. Many people therefore have a permanently installed LPG tank retrofitted for the motor caravan. Unlike conventional single-cylinder or two-cylinder systems, these LPG tanks require other components in the gas system – especially if you wish to heat the vehicle while driving.
LPG tanks are available in a wide range of versions for leisure vehicles. Wynen Gas, for example, talks of up to 23 different sizes between 20 and 195 litres of capacity on their website. While the conventional 11-kilogram gas cylinder holds just under 22 litres, the largest LPG tank nominally holds 195 litres; however, due to the filling stop at 80 percent, only a maximum of 156 litres fits inside. However, this is still more than seven times the largest gas cylinder.
Major consumer or long-term camper?
In other words, if you need a lot of gas on your holidays or, for example, are a long-term camper, you will have already considered buying an LPG tank once or twice. Or you have already managed to install a tank.
For the operation of such LPG tanks, there is not much needed for the downstream gas system. As is often the case, the gas pressure regulator or the gas pressure regulation system is the most important thing. If you can retrofit an LPG tank, you usually have the control device from our Caramatic line installed directly.
Observe replacement period
At the latest when the first exchange is due after ten years, the camper should also familiarise themselves with the subject matter. And at the beginning, the question is usually: Do I want to heat the motor caravan while driving or only during stationary operation?
Heating while driving
If you have the right components for heating while driving, you can enjoy a special level of comfort. Namely that of a preheated living room when you arrive at the site.
The basic requirement for heating while driving with the permanently installed LPG tank is a crash sensor as part of the gas regulation system. For this purpose, GOK offers the Caramatic DriveOne in two versions (image): One for the alignment of the LPG tank fitting plate at a 90-degree angle and at an angle of 105 degrees.
The DriveOne is connected directly to the LPG tank on the input side and with the piping on the outlet side. The camper does not need any more components for the gas system itself.
If you only have to operate the gas system when the vehicle is stationary, you do not need a crash sensor as a safety device. Therefore, you do not need to consider the alignment of the LPG tank fitting plate. A “standard pressure regulator” is sufficient, of course, with the appropriate connections.
GOK offers two different gas pressure regulators for the stationary operation of gas systems in leisure vehicles with LPG tanks:
- Gas pressure regulator with outlet pressure 30 mbar, test point and over-pressure safety device S2SR
- Gas pressure regulator with outlet pressure 50 mbar, toggle valve and shut-off valve for leak checks, quick coupler and pressure relief valve PRV
GOK offers the right options for the operation of LPG tanks in the motor caravan – depending on the exact purpose and working pressure. The camper has the freedom of choice and should observe the installation and operating parameters.
