Detroit Diesel Engine Saver® Model 551 alarms on low coolant flow, low coolant pressure, or high coolant temperature. Whichever happens FIRST. It’s the only unit that does.

Overheating and cooling related problems are the most common cause of downtime on Detroit 8V92, 12V71, 12V92, 12V149 and 16V149 series engines operating in mining, construction, marine, and power generation environments. By monitoring temperature, coolant flow, and pressure instead of just temperature, problems in their earliest stages are caught well before overheating damage occurs. The result is maintenance savings and increased productivity.

The Model 551 will work with any Detroit 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 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. Check out the installation procedure.

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, scores a cylinder, or seizes, damage is done. Engine Savers are designed to catch these problems before it gets to that stage..

The Model 551 monitors water flow into the radiator or heat exchanger, oil pressure, crankcase pressure, 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.

Here's What it Does...

The Marine 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

Clogged breathers
Worn pump impellers
Worn bearings
Governor failure
Loose radiator cap
Scored cylinder
