A system for extinguishing and/or inerting, including an extinguishing-agent tank, a conveyor device for an extinguishing agent, a pipeline, and nozzles. A synthetic liquid extinguishing agent (12) is stored at low pressure of up to 3 bar relative to 21° C. in the extinguishing-agent tank (1) and at least one incidence sensor detects fire signals and reports them to a fire detection panel and/or control panel (9) which activates the conveyor device (4) that conveys the synthetic liquid extinguishing agent by means of a pipeline (5) to nozzles (6), and the liquid extinguishing agents transitions into the gas phase after leaving the nozzles (6). The system represents a more cost-effective system that requires less technical efforts in comparison to previous systems having synthetic liquid extinguishing agents.
