What is the difference between the types of extinguishing?
The extinguishing method with inert gas flushes the heater chamber with the gas. The inert gas displaces oxygen and the fire goes out. It must be ensured that enough inert gas is available to fill the whole heater.
The extinguishing method with water mist, beside the displacement of oxygen, the hot surfaces are cooled additionally. This has the advantage of inhibiting a new ignition the oil after the extinguishing process.
