Monitoring and controlling - decision-making made easy

Automated and intelligent control systems are a crucial tool for optimizing performance. They offer proactive advice on how to improve availability, safety, and efficiency. 

Engine automation control retrofits replace old engine controls with MAN SaCoS retrone or MAN SaCoSone, enhancing availability, maintainability, and performance.

An MAN Electronic speed governor retrofit is easy to integrate with electronic engine governors. Improving availability, start behavior, and load acceptance, the digital control system reduces soot emissions on start-up and supports load sharing in multiple-engine applications. 

Ergonomic and intuitive, a Multifunction Monitoring system replaces most existing monitoring systems with a single control cabinet. It monitors safety features and the main engine parameters, from the exhaust gas to bearing, from oil crankpin to casing pressure.

Smoother and more efficient operation with constant lube oil monitoring

With the MAN Fluid Monitor, you track changes in your engine’s lube oil. Consistently monitoring the quality, this autonomous and intelligent solution detects degradation and pollution early-on and alerts the operator from tiniest to critical changes. By giving you a near real-time 360° view of the main operating lube oil parameters, the MAN Fluid Monitor mitigates the risk of lubrication-related engine failures and systems breakdowns.
