Red paint, valve protection, carrying handle: this is what a traditional camping gas cylinder looks like. Using the LPG in the cylinder for heating, cooking and cooling requires a gas pressure regulator. This reduces the cylinder pressure from maximum 16 bar to 30 mbar – the working pressure of the gas-operated appliances in your caravan. Truma has several gas pressure regulators to choose from, depending on whether you plan to use your appliances while driving or only when your motor home is parked, and whether you use little or a lot of gas.
If you use your gas system only at campsites, in other words, when the caravan is stationary, all you need is a classic Truma gas pressure regulator for one or two gas cylinders. Gas pressure regulators for two cylinders have the advantage that they switch automatically from the empty to the full cylinder when the pressure of the operating cylinder falls below 0.5 bar.

Some safety regulations must be fulfilled so that you can continue to run your gas-operated refrigerator or heater while you’re driving. For example, you must ensure that no gas can flow uncontrolled from the cylinder in case of a traffic accident.
Truma has therefore developed gas pressure regulators that contain a crash sensor. In the event of a crash from about 15 km/h, a small ball in the regulator is released from a holder and closes the gas line, meaning no gas can flow. If the crash sensor is triggered due to bad road conditions for example during the trip to the holiday destination, you can simply reset it with a reset button.
Truma gas pressure regulators are easy to retrofit and are connected to the gas cylinder with high-pressure hoses with hose rupture protection. Your Truma expert will not only advise you which Truma gas regulator suits your needs best, they are also the person to speak with to have it installed.
Checking the gas system
When a new regulator has been installed, your specialist workshop can carry out a gas check. It checks that the gas system is installed correctly and that it has no leaks.
You should use a gas filter so that your gas pressure regulator works reliably for as long as possible. It keeps aerosols away from the gas pressure regulator and seals. These are oily particles in the gas cylinder that can block the regulator.
