The gearhead is 150-250*....

Anybody use any of these? I have Spal dual fans and was thinking of buying 2 and installing 1 for each fan. Say one to come on at 190* and the other at 200*. I like the Derale so far. It looks simple and less likely to break and simple pod adjustment.

Spall is comming out with a new controller .. dew in June

All adjustable's need a 20 degree sepperation between on and off points .. same thing with the standard temp switch .
you dont want to go below 175 on off point anyway .. you would have to run a t/stat below 180 ...not good for moisture in the oil pan

Just a thought .. run one fan on the temp switch comming on at 195 .. and the other on a simple toggle to ground to turn on when you want it .
the relays are only looking for ground to fire up the fans .

Whats the reason they have a new one comming out? Problems? I can wait, I just want to have the least amount of problems. The only sure way would be a simple relay setup, but I want to be able to adjust to my needs. Is it REALLY comming out in June?

I have the SPAL PWM and I like it. When the temp comes up into its range, it doesn't come on full blast, just enough to keep things in check. If the cooling demand goes up, the speed of one fan goes up. When things get critical, the one fan is going full speed, and the second kicks on.

From what I heard, they are making it so there aren't harness wires hanging off, they will plug into the module. They will also have an indicator light to signify that it's alive when the motor is running off and no fan is needed. They said the control logic algorithms won't change.

I called SPAL a few weeks back and they said it would be June before the new and improved PWM's would be available... then we just got in several from SPAL last Friday.

A bit more expensive, but I have this one my '70 with dual 12" and Alumitech.
