Derale A11 Dual Powerpack

Note: This assembly is intended for primary cooling and should provide enough airflow to replace your vehicle's factory fan, but you will still need to determine the CFM requirements for your engine before making your purchase. Engines that have been modified or vehicles used for towing may require additional CFM. There is no limit to the number of fans you can install, as long as they fit appropriately and are mounted on the same side of your radiator so that they do not cancel each other out.


You can install the Dual Powerpack as a horsepower-boosting replacement for your belt-driven radiator cooling fan, or you can use it to upgrade or expand to your current electric fan system. The dual fan cools your engine by pulling 3,750 cubic feet per minute (CFM) of air through your radiator at 0 static pressure. High-output, 225-watt motors and skewed fan blades do the job efficiently and quietly. The Powerpack keeps engine loads to a minimum by drawing power (37.4 amps) from the alternator - not the engine itself. The fans are neatly packaged in a slim, customizable aluminum shroud that offers multiple mounting locations and won't hog lots of space in your engine compartment.


Power Increase Compared with Belt-Driven Fans

Belt-driven radiator fans draw power from your vehicle's engine, which causes a mechanical load that robs the engine of valuable horsepower and torque. The Powerpack, on the other hand, gets its power from your vehicle's alternator, via your vehicle's 12-volt electrical system. The Powerpack's 37.4-amp draw is far less taxing to your engine than a belt-driven fan's mechanical load. So replacing your belt-driven fan with an electric fan system can increase available horsepower and torque - and even improve fuel economy.


Increased Cooling Efficiency

The Dual Powerpack pulls mass quantities of air through your radiator's fins using twin fans, each powered by a 225-watt motor. The patented, skewed fan blades are designed to move air with as little noise as possible. Each fan grill is actually a stator flow director that helps produce maximum velocity by aiming the outflow.


Temperature Control Options

You can control the Powerpack with an on/off switch or a thermostat. An on/off switch, such as the Derale lighted on/off switch for electric fans (D16740), lets you control the fan manually.


A thermostatic control, on the other hand, turns the fan on when the coolant temperature climbs past a certain level and turns it off when the temperature falls back to a certain point. The Powerpack works with Derale single-stage thermostat switches (sold separately) with preset temperatures or adjustable temperatures.


Rustproof Aluminum Shroud

The Powerpack's rustproof aluminum shroud can be painted, polished, anodized, or left with its natural finish for a custom look. The shroud also serves as a wind tunnel so that air exits the fan quickly. Built-in air pressure relief vents help keep the static pressure load in check.

  • Electric Fan Setup Recommendation for 1996 Dodge Ram with 5.9 Liter Cummins
  • For a fan setup that would work well for your 22-1/2 inch wide setup the Derale 22-1/2" Dual, High-Output Electric Radiator Fan w/ Aluminum Shroud # D16830 would be a fantastic option assuming it would fit for a vehicle like your 1996 Dodge Ram with 5.9 liter Cummins that would need some serious cooling power.

  • Dual Electric Radiator Cooling Fan Setup for a 1971 Dodge Demon
  • The fan shroud on the Derale High-Output, Dual Radiator Fan-and-Shroud Assembly part # D16812 is about 1-1/4" thick but the space between the fans is only about 2". Therefore, I would not recommend going this route. Unfortunately, due to the 2-3/8" of clearance from the radiator to the outer knob on the water pump, your options for a puller electric fan setup is almost non existent. Therefore I have two options for you. The first option you have would be to replace the water pump pulley...
