Derale Performance is changing the rules of engine temperature control with Smart Technology brought to your car's cooling system through Derale's Patented PWM Fan Controller.
Historically, cooling fans run at 100%, even when less airflow is needed, constantly turning on and off as the engine temperature changes. This REACTION based temperature control system causes constant amperage spikes, excessive noise and premature wear. The Derale PWM fan controller continuously monitors your engine's temperature, therefore CONTROLLING the temperature and increasing the vehicles cooling efficiency, while reducing the amps used to do so.
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. Using Soft Start Technology, fans ramp up slowly which eliminates harmful AMP spikes. The unit will continuously monitor your engine's temperature and operate the fans at the optimum fan rate as needed between 1 to 100%. The net result; the electric fans often only run between 40-60% to keep your engine cool. Additional benefits include, reduced fan speeds which means reduced fan noise, which tends to compete with that sweet sound of your engine!
This multi-fan controller has a built-in A/C Over-ride circuit and is designed to control as many 12 volt brushed electric fans as desired, up to 65 Amps combined. Even better, installation and calibration is a snap. It simply installs into a Derale Dual or Single Fan configuration and wires to your vehicles battery; adding in a simple multi-meter and a twist of the temp adjuster, allows you to program the temperature to maximize your car’s cooling system.Specifications: Amp Rating: 65 amp
