How to find the right Truma gas pressure regulator

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.

Gas pressure regulators for stationary operation

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.

Gas pressure regulators for operation while driving

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.

Installing the gas pressure regulator

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.

Gas filters protect against dirt

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. Check the filter cartridge regularly, such as every time you change the cylinder, and replace it if necessary.

Tips for safe handling of your gas system

  • If you also operate your gas system while driving, you need a gas pressure regulator with crash sensor as well as hoses with rupture protection. In case of damage, the safety device is triggered and immediately stops the gas flow.
  • If you do not have a crash sensor, gas cylinders must be closed while you are driving.
  • Gas cylinders should be supported at the top and bottom so that they cannot move around and should also be connected firmly to the vehicle.
  • Check the hoses every time you change the cylinder by bending them slightly. If they are brittle and cracked, replace them as soon as possible.
  • Transport gas cylinders only in a cylinder box: This is sealed to the vehicle interior and has an opening of 2% of the base area, but at least 100 cm². The opening leads outside so that emitted gas can escape directly.
  • LPG appliances must not be used when refuelling, in multi-storey car parks, in garages or on ferries.
