By monitoring temperature, coolant flow, and engine pressures instead of just temperature, the Model 551 Detroit Diesel Engine Saver will detect problems in their earliest stages well before overheating damage occurs. Your benefits include maintenance savings and increased productivity.

Detroit Diesel Engine Saver® Model 551 alarms on low coolant flow, low coolant pressure, or high coolant temperature, whichever happens FIRST.

The Model 551 will work with any Detroit Diesel engine whether it has DDEC or not and adds essential protection features not found with DDEC. The Model 551’s specifications, features, and trip point adjustment ranges are configured to the unique operating characteristics of the Detroit Diesel 2-cycle engine. On-unit displays (remote display also available) shows continuous reading of coolant flow, power, enabled status and alarm conditions.

Flight Systems has been saving engines in mining and industrial applications for over 30 years with our Model 550 Engine Saver. We've got an impressive track record of success. Installation of the Model 551 takes about 6 hours and is not difficult.

The Model 551 will immediately notify the operator before the engine overheats in addition to loss of oil, broken rings, etc. so that preventative action can be taken. Once the engine overheats or a cylinder is scored or seizes major damage is done. Engine Savers are designed to catch these problems before it gets to that stage.

The Model 551 monitors fluid flow into the radiator or heat exchanger, oil pressure, crankcase pressure, Engine RPM, coolant pressure, and temperature and exhaust system cooling water temperature. It operates on 12, 24, or 32 volt systems and incorporates circuitry to eliminate false trips and it is designed to operate in the heat, corrosion and vibration common to heavy industry.
