Derale's PWM Fan Controller: No More Shocking The System

derale fan controller

Typical fan controllers, however, only allow the fan to operate at two speeds: 100% and 0%. The current spikes on our Valiant went down from 50 amps to a max of 23. The top of the inner fender on our Mopar provided the perfect spot. Here's how it works; The controller monitors your engine temperature via the cool side of the radiator, therefore providing a more accurate reading for your cooling system. After a hard pass with the fan Derale controller set at 160F, my engine would be at 180F. This Teflon insert presses with an interference fit down into the cut off and drilled hose barb fitting: The probe ribs were machined into a barb angle. Of all the controllers I tested in summer of 2015, this Derale controller was best.

Suffice it to say it works damn good. The voltage gauge used to drop to 13 volts when both fans kicked on, and now it stays above 14 volts most of the time because the fans begin keeping the temperature down without the full draw. My goal was to have proper sensor operation while finding a way to use the original Derale thermistor assembly. Derale performance oil and fluid coolers are custom engineered for race environments where space and weight are at a premium and cooling demands are relentless. The included 50 amp circuit breaker will protect the conrtoller, and the 65 amp capacity will allow you to control up to four electrical cooling fans.

One solution to remove the human element is to , like the type that we used on. Measuring the voltage will give you an idea of where to set the controller. This smooths out the temperature swings in the system, making the low and high extremes closer together. This newly redesigned adjustable electric fan control kit is designed to activate up to 2 fans with a total maximum draw of 25 amps. Like in your home, when a switch is flipped on in your car, current from your battery will travel through the component using as much as it needs. Even though the fan may not be at 100% speed, it will still spin at a lower rate and still pull some air through the radiator.

Unfortunately, both fan clutch types operated at engine speeds, so even fully engaged neither one was capable of pulling sufficient air through the radiator at idle on a blistering summer day. In this case, the Customer Care team will remove your account from auto-renewal to ensure you are not charged for an additional year and you can continue to use the subscription until the end of your subscription term. One wire from the positive terminal of the battery feeds the system on one post. Adjustable from 150F to 240F. The housing becomes part of the thermal measurement circuit, rather than just the probe tip that physically contacts the air or water stream we are trying to measure.

Yes the controller breaks the ground not hot wire works great. Also, with ShippingPass, there is no need to worry about commitment. Upgrading to an electric fan works great on a musclecar; at idle the fan helps to keep the temperatures down, and they are a good solution to overheating at long stop lights. I wanted a straight low-restriction air flow path to the throttle body, so the intercooler sits on a platform just above the water pump. Rated 4 out of 5 by Slick from I purchased this control because the first Derale controller would not function as advertised. Installed clean and looks nice.

Adjustable fan controller turn-on range from 150°F - 240°F, and turn-off preset at 10°F lower than turn-on. We chose to install the controller about the only place we had room for it on our 1965 Mustang, Project Biting The Bullitt. When trouble strikes, you do what you always do and rely on the help of knowledgeable friends. Historically, cooling fans run at 100%, even when less airflow is needed, constantly turning on and off as the engine temperature changes. The override circuit actually changes pulse width in a very linear fashion with voltage.

Heat can damage the pump, the higher current wears down brushes faster. This is a departure from the common practice of using a thermistor in the water pump housing or intake manifold. I decided to eliminate the belt driven pump and fan in favor of an electric pump and electric fan. A proprietary aluminum temp sensor that reacts 50 % quicker than typical brass probe-style sensors sticks to the outside of the tank with double-sided tape. Includes all wiring and detailed instructions. High amperage causes heat, and when fans are controlled by relays those amperage spikes cause high heat in a short amount of time.

DERALE PWM Fan Controller review

We did not use this one. I decided to make an adaptor adapter from a standard brass hose barb that fit my manifold port, a short piece of brass or copper rod, and a chunk of Teflon rod to seal and thermally isolate the probe from housing. Because I was having issues with engine getting too warm, I didn't adjust the temp. Instead, both fuses had melted arrow and their fuse terminals were baked to a crisp. Derale provides the following sensor left side below compared to hose barb fitting : I made a sensor adaptor out of a hose barb fitting. Both sensors need to be mounted close to the lower radiator hose outlet.

Additional benefits include, reduced fan speeds which means reduced fan noise, which tends to compete with that sweet sound of your engine! Mechanical pump cars normally use a thermostat bypass hose to allow cold circulation. The unit will continuously monitor your engine's temperature and operate the fans at the optimum fan rate as needed between 1 to 100%. Adjust the potentiometer to set the 'fan on' temperature based on the chart included with the instructions. This happened on all 3 I have installed. Using Soft Start Technology, fans ramp up slowly which eliminates harmful amperage spikes. I put a taper on the ribs that allow it to push into a hole and lock, just like a normal barb is machined.
