The DESMI fixed fire fighting system is developed to suppress or extinguish fire at an early stage before releasing the total flooding system as required by SOLAS Ch.II-2/Reg.10.5.6.1&2 for ships constructed on and after 1st July 2002. The FineFog water mist has a highly suffocating and cooling effect and with the DESMI FineFog you can therefore protect the inflammable objects in accordance with SOLAS requirements (e.g. main engine top, auxiliary engine top, heated fuel oil purifier, oil fired boiler front, incinerator burner, oil fired inert gas generator etc) without having to shut down engine, evacuate personnel or seal off space.
