Truma SecuMotion Gastank
The Truma SecuMotion is a gas pressure regulator designed for liquid gas systems in vehicles, ensuring a uniform outlet pressure of 30 mbar. It features an integrated gas flow monitor (GSW) that automatically shuts off the gas supply if the nominal consumption is exceeded or if the downstream pressure drops below 27 mbar due to a pipe break.

Frequently Asked Questions
Q: Can the SecuMotion be used in closed rooms, households, or on boats?
No - it's strictly forbidden to use this regulator in enclosed spaces such as houses, mobile homes, or boats.
Q: Is it permitted to operate the heating system while driving?
Yes - across Europe, a type-tested liquefied-gas heating system can run while driving under EU directive 2001/56/EC, as long as the gas installation and regulator are set up correctly.
Q: How do I reset the gas flow monitor (GSW)?
Open the extraction valve, press the regulator's green GSW reset button slowly, then release it slowly over about 3 seconds. If you feel no resistance when pressing again, the regulator's ready to use.
