Has anyone figured out what size fan it will take to keep a Kubota 950D Diesel cool using the stock radiator remotly mounted?
I have been looking at the 10 inch and 12" Hayden fans. The 10 Inch would fit the radiator shroud without too much trouble but I wonder if bigger is better in this case.
Any thoughts? |

David,
Is this engine for a genset? If so, you might want to look at 120-vac fans instead. More bang for the buck. The squirrel-cage variety work nicely -- mine's a Dayton, available through Grainger and others.
In any case, building a ducted enclosure for your remote radiator will get you by with a smaller fan than trying to use the stock shroud.
FWIW.

The 13 KW generator I got from Wrico requires 2550 CFM and the use of a shroud to ensure all the air goes through the radiator. My radiator is remotely mounted. I'm not sure how that tranlates to the 950D you have.
What I ended up using due to space requirements was one of those 12 volt Zirgo, 16" fans of the two dogs saga. While it's specs say it will move 3650 CFM, Dick Wright points out that it will probably not have the longevity of one of the 120 volt Dayton squirrel cage fans.
We'll see how it lasts, but for now it seems to work well enough. |

__. Both the earlier responders are correct, a "squirrel cage" (centrifugal) fan is a much better choice for moving air through a matrix that's giving lots of drag. A plain blade fan will NOT build up pressure (or vacuum on the other side) -- it will only move air along in what are basically "even pressure to even pressure" situations. If you really need to build up pressure (or vacuum) to move air, the only way to go is with a centrifugal blower.

Well, Hmmm...
I guess that 2-speed 220 volt Blower unit that I pulled from an old Ma-Bell manhole ventilator pack will work. You know, The ones with the bright yellow 8" hoses that they drape down into the manholes...
Having useful junk laying around is handy sometimes.
Now to figure out where to mount that monster.
Thanks Guys.... |
