Industrial gas turbines, which are used in the oil and gas industry, for example, drive generators for power generation or compressors (mechanical drives) for gas compression or gas liquefaction. The op-erating temperature inside turbine acoustic enclosures can reach up to 120°C and the surface temperature of the turbine itself up to 800 °C. Oils leaking from the leaks in oil pipelines can easily get ignited on these hot surfaces. Once lit, a fire can quickly spread to other areas due to the high air flow rate actually used for cooling. Long downtimes and higher costs are often the result. Carbon dioxide extinguishing system ensure quick, residue-free fire extinguishing, even in areas which are difficult to access. In large turbines low pressure CO2 extinguishing systems are frequently used, since due to the liquid storage only a small amount of space is required for a lot of extinguishing agents.
