Butler design of fan is changed and different....
They pull way more air, and have a few simple modifications that make it pull the air to cool everything in the motor compartment, the transmission, fuel pump...you can feel air all the way to the back of the van.
In Vegas in 2015, we ran our new
Butler hard....110 degree heat, and I basically fired it up and ran it hard during the show for a pretty strong 4 hours a day....no problems.
I had almost 16 hours on the new
Butler before it made it to Minnesota.....
Heat is not a worry of mine these days with a
Butler...
They even have special belts they have worked on for hotter environments such as Texas hot heat.....another reason, I just by the belts from
Butler too.....matched sets...and made for high temps.
