The ideal 6kW generator set is small and
lightweight. The M673L3 certainly qualifi es. But it stands apart through its remarkable long-life reliability. The reason? The M673L3 runs at 1800 rpm (1500 rpm for 50 Hz), instead of 3600 rpm.
Consider that during only 2000 hours of
operation the 1800 rpm M673L3 will turn 216
million fewer revolutions than a 3600 rpm
set. Its pistons will travel 38,522 fewer miles.
Its cylinders will withstand 108 million fewer
detonations. Which engine do you think will
give more years of reliable service? We couldn’t agree more.
The M673L3 has a balanced Lugger three
cylinder diesel instead of a rough two banger.
Four plateform isolation mounts reduce
vibration transmission even more.
For maximum comfort afloat the new
M673L3 has a Sound Maze air intake system.
Air enters through a molded rubber hose and an acoustic dampening chamber. Air goes
in but much less noise gets out. For maximum sound attenuation, specify a sound enclosure. It is constructed of electrogalvanized steel panels with a powder-coated auminum extruded framework, and creates a 23% smaller overall package than previous versions.
The generator’s automatic voltage regulator
is powered by an auxiliary AC stator winding
that isolates it from the main windings. The AVR always has clean power to provide excitation for faster load response and better motor starting.
Your air conditioner and other motor driven
equipment will love being matched with the
673.
A 30 amp AC circuit breaker in the junction
box protects your wiring. Safety shutdowns
for low oil pressure, high coolant temperature and high exhaust temperature protect your engine.
The M673L3 meets US EPA Tier III
emission standards. You, your moorage
neighbors and the environment will all
benefit.
1800 rpm reliability, low emissions, quiet
operation and strong motor starting. Good
things do come in small packages.

 

Enclosure Package is 23% smaller than previous design!
