The Kidde Graviner 53836-K269 is the detector head assembly for the advanced Mk7 Oil Mist Detection (OMD) system. This critical safety device is engineered to provide an early warning of oil mist build-up within the crankcases of diesel engines. By continuously monitoring the density of oil mist, the Mk7 system can preemptively alert operators to potential overheating and seizure of bearings or other components, thus preventing catastrophic crankcase explosions. Utilizing proven light-scattering technology, the Mk7 detector head offers reliable and stable performance with a high resistance to false alarms. It is an essential component for ensuring the safety of machinery and personnel in marine, power generation, and industrial applications, and is designed to meet the stringent requirements of major marine classification societies.
