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 4,000 cubic feet per minute (CFM) of air through your radiator at 0 static pressure. High-output, 300-watt motors and skewed fan blades do the job efficiently and quietly. The Powerpack keeps engine loads to a minimum by drawing power (24.8 amps per fan) 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 24.8-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 300-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.

Video Transcript for Review of Derale Radiator Fans - Dual Electric Radiator Fans - D16838
Michael: Hi there, I'm Michael with etrailer.com. Today, we're going to take a quick look at the Derale high output electric radiator fan. This high output dual radiator puller fan helps to maintain the optimal engine operating temperature inside your vehicle's engine compartment. It's going to efficiently move 4,000 cubic feet per minute of air at zero static pressure. You can see we've got two fans here that are each a 12 inch diameter fan. Each fan is going to pull 2,000 cubic feet per minute to give us that combined total of 4,000 per minute for the unit.
This is going to draw its power from your alternator, not your engine. So it's going to have minimal, indirect mechanical load on it. It's going to make it easier for your engine to operate without having to power up your belt driven fan. So if you're replacing a belt driven fan with this fan, it might help to increase your horsepower and torque because your engine will be doing less to run the fan.Each fan is powered by a 12 volt 300 watt motor, that's going to draw 24.8 amps. This is a waterproof motor, so it's going to resist moisture and dirt as well as dust.
So you're not going to have to worry about it over time. It's got an IP rating of 68. So it's going to keep all those contaminants out and stay working well. Our fan blades are a skewed design, so they're going to help move that air efficiently and quietly. Our shroud here is a vented shroud.
So it's going to help increase the air flow velocity, basically acting like a wind tunnel to help move that air through. We do have built in vents here that are going to relieve excess air pressure if needed. And the shroud itself is constructed of an aluminum, so it's going to be rust and corrosion resistant. Again, last a nice long time. Hold up well for you.This can be painted, polished or anodized depending on your preferences.
And as far as our measurements go, this is right at 28 and a quarter of an inch wide by right at 17 inches tall. And then for our depth, going to measure not only just the shroud but also the motor as it's sticking out as well. So we're looking at right about four inches in depth. This is designed for either top or side mounting. All of your brackets and hardware that you're going to need are included, as well as instructions with pictures to help you get everything installed properly. So it should be pretty easy to get put in place. Now, to operate this, you can use an on off switch to control it manually, or you can also add in a thermostat that will read the temperature of your coolant and turn on the fans when your coolant needs to drop in temperature. And then it'll turn off once it reaches the desired temperature. Both those options, the thermostat and the on off switch, are not included in this kit. So you will have to provide those separately. But it should be pretty easy to get that sort of thing installed.This is made here in the USA. So you can trust it's made to the high quality standards that we've come to know and trust for products that are made here in the US. And it does come with a one year warranty, so if you we're to have any problems with it, you could give us a call, we'd be happy to work with you on that. We always want to make sure that our customers are getting quality products and having a good experience with us. But I really don't think you're going to have any problems with this. I think this is going to do a good job of helping to cool down that coolant so that your whole engine compartment runs the way it's supposed to and help to increase that horsepower, reducing the amount of strain on your engine to power your fans.So that's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.
