Chipper radiators.

[MATTMOSS]

Have a think sbout it and see if you can decide why they dont make them like that, if you cant figure it out read on

 

 

 

It has been done with a counter veined viscus fan but its expensive. Engines come with a pull van mounted behind the rad becsue most engines travel forward in a vehicle and dont suffer the dust problems.

 

Its easy and CHEAP for the chippr manufacturer to fit the bog standard unit thats why they dont make them like that

 

I thought somebody as knowledgable as you would of figured another way around this by now.

The fan on my Vermeer blows rather than sucks so the rad doesn't get clogged :-)

Didnt you read it? I gave you the other way around it:001_rolleyes:

A few weeks ago I was watching a large Jens chipper chipping logs for biomass.

Air was being sucked through the radiator via a mesh screen similar to most chippers.

However every ten minites or so the cooling fan stopped and either reversed the fan or there was another fan that came on very powerfully and blew any debris out of the grill for a few seconds.

I thought- a good idea- but if its capable of blowing air out through the radiator, then why still choose for the majority of the time to be sucking air in and risking clogging the radiator?

If you can work this out yourself you dont need to read on.

 

 

Its because there is restricted airflow in the engine compartment and the air in there is sufficiently hot to stop the radiator cooling efficently.

Of course,................. I defer to your many years of mechanical engineering and chipper modification:001_rolleyes:

Hows the desk and shiny elbows treating you these days?

If you genuinely believe that small difference in ambient temperature would be enough to adversely affect the cooling system how do you suppose these machines work in hot country's ?

Someone told me that Timberwolf fans blow air out of the engine bay through the rad - I'm not sure if that's true as I've never checked but if so then it's a nice bit of intelligent design. Shame they can't sort their bearings out though!

OMT - take the radiator out altogether if it is totally blocked - poking stuff through it with bad access will damage the fins and possible puncture the core. Get hold of an air line (as big a compressor as possible as this is a very air hungry operation) and blast as much crud out as you can, working systematically from one side to the next. Start by blowing it back out the way it came in, and then back the other way. Repeat the process in 12 months time...

E last late 190 I worked with certainly didn't, grill was permanently clogged with rubbish.
