1500 RPM is an interesting speed for a North American gen set in this size.

OOpsie....so they will get 50 Hz....

I know of (2) engine makers (but couldn't identify
them If I tripped over one) That it might be:

Jenbaucher (spelling error I'm sure)
MAN

In case you don't remember Smokin' changed jobs (again) last summer. The company he works for imports Guascor engines from Europe. Big engines but all gas-pots--well, all spark fired at least--they may run on different fuels. This just looks like a big brother to the others--the name tags say Siemens but I suspect the base engine is actually made by Guascor.

As to the Hz I'd be really surprised if they sent a 50 Hz engine to North America.

There are some pics of other Guascor engines in Post #20 of this thread...

If the engine can be run at 1800 RPM and give satisfactory life that is what they would run it at.
If not they could run it an 1200 Rpm using a 6 pole generator.

They can also use an invertor generator where the rotating parts and some diodes make dc then the inverter converts the dc into AC but at that power level my research has not indicated a clear concensus.

Kieth as engines get larger all the moving parts get heavier. Rotating speed translates into piston speed and acceleration/deceleration within the bore along with side thrust forces and other limiting factors.
some of the larger ships engines have top speeds of 100 rpm and designed running speeds of 70 - 90 RPM.

.
I have seen it done with grid tie 6000 hp diesels.

So maybe they are running D.C. and an inverter, the cost
is coming down on that stuff.

I had read that he quit cummins, but didn't follow the new job (I thought
it might have just been a repair facility)

50 Hz could have been sent as a mistake...happens all the time.

1500 was listed as the rated rpm. Might not be the normal operating rpm.

I'm surprised for what it cost, they only made a wood shipping pallet, not something
made of box tube.
Siemens/dresser-rand/guascor (kind of like Agco/White/Oliver)

No clue on oil capacity, the 56 liter engine hold 60 gallons.

An engine of that size would normally be a SAE#1 or bigger..kinda looks like a smallish #3 FWIW
All electronic, Woodward brand.

The pic does not do it justice. It's massive.

We mount a gear box to turn the gen end at 1,800. MAN and the big siemens engines dont go fast enough, as noted. They claim 98% efficiency on the gearboxes.

We have diesel standbys up to 60 liters but our main focus is the natural gas, propane and Biogas gensets. Biogas is our number one seller along with digesters so we can keep the lights on with cow farts.

Siemens bought guascor and is phasing their name and colors out.

Gearbox drive makes it sound if the company is small time, and is picking
from a catalog. But it must pencil out. Running a 6 pole alt at 1200
should be cheaper to build, and cheaper maint.

Does the gearbox mount inside that extended bell housing ?
Maybe a planetary gearbox ?

60 gallons of oil sounds awfull small amount for an engine of that size.
FWIW a 4400 hp diesel engine on a loco uses 8 barrels....

I work with a contract engineer once in awhile, he did a garbage mound
power house set-up very similar.

He said the gas is very dirty, and needs cleaning, had a couple of filters
in series to clean it up before the engine.
