The Model 550 will monitor your engine throughout its full RPM range and alert the operator or shutdown the engine if any temperature or pressure deviates from normal settings based on actual operating conditions.
Proven effective protection where normal monitors fail and highly recommended for up rated or heavy use applications. Cummins supplies the Engine Saver with their new up rated K series – Cummins p/n 3627061.
Installation reduces warranty costs on engine rebuilds and saves money on high maintenance costs as well.
The Engine Saver® monitors a combination of pressure, temperature, and RPM on 8, 12 and 16 cylinder diesel engines. It detects early signs of trouble before damage occurs – long before an attentive operator could detect it on the gauges and without false alarms. Most common faults go undetected until they cause consequential damage or engine destruction.
The Engine Saver® Detects
- Low and /or loss of coolant
- De-aeration baffle fatigue
- Broken/worn rings
- Hole in a piston
- Loss of oil
- Partially blocked oil or water pumps
- Fuel dilution
- Overspeed
- Overheating
- Clogged breathers
- Worn pump impellers
- Worn bearings
- Governor failure
- Loose radiator cap
- Scored cylinder
