Electric fans for radiators have been discussed extensively. If they are so good, don't you think OEM's would have been using them since they are easier to set up then a direct drive or a hydraulic drive and they take less horsepower drag? On big rigs, they had a setup that had 6-8 fans (depending on the radiator shape) and didn't work on a front radiator! Trying to get an electric motor that will pull like a 32" 8 bladed fan (the equivalent of 30hp) just won't happen. 30hp with a 24v electric motor would have to draw about 950 amps! With our side intake radiators, the only way to go is with either a direct drive or hydraulic motor setup. We've had too many members try electric and by now have realized that using an electric motor for the radiator is like banging your head against the wall because it feels so good. Good Luck, TomC
The engine isn't always the limiting factor in HP available to move your bus - heat rejection abilities of the radiator can limit things too.Sure electric motors can do it & use the batteries to buffer the peak power required from the main engine - BUT - the electric fan will HAVE TO move the required air to keep the temps in line during peak demand. That means the elec motor MUST be capable of that level of horsepower (which is in excess of 20 HP).
Yep he did do it right Kyle but some of these guys say it won't work period with electric fans that is point I am trying to get across it will work if done right good luck
so I was suggesting maybe keep what you have 'til you find a good solution, in the mean time a new rad will keep you on the road.
