If diesel-powered generators are not an option, AURORA recommends this FORD gas-powered engine-generator instead. FORD Industrial engines such as this MSG-425 model is used in a wide range of products and operating conditions. It is suitable for hot, humid climates to cold and higher altitudes where others struggle to perform. The use of an oxygen sensor to continually monitor fuel combustion lets the engine adjust the air and fuel mixture to maintain optimal performance under harsh conditions.

The MSG-425 FORD engine can be configured to use gasoline, natural gas or propane. Since it is radiator cooled and runs at 1800 rpm, it can run full or part-time as needed.

Welded channel steel frame supports the generator with vibration mounts. Mounted to it is the battery tray, control panel assembly and mains circuit breaker panel. The configuration is customizable to meet customers specific needs. The general specifications are shown below. Lead times may vary, contact AURORA for a detailed quote.
