Keeping engines and Machinery Spaces Safe

QMI (Quality Monitoring Instruments) has been at the vanguard of engine and machinery space fire protection since pioneering oil mist detection systems in the early 1980s. The need to monitor the accumulation of oil mist in an engine’s crankcase and machinery spaces was first recognised when it was confirmed by P&I Clubs that up to 65% of all ship fires are the result of pressurised fuel and lubricating / hydraulic oil droplets collecting in the atmosphere.

Triplex and Multiplex monitors incorporate a ‘traffic light’ system on each channel to ensure that operators know on first glance if there are hazardous concentrations of oil mist.
