The Dual Fan Controller Thread In (DERALE part number 16789) is a high-amperage engine cooling fan controller designed for vehicles requiring independent dual-fan management. This adjustable temperature-activated switch is ideal for custom cooling system builds, engine swaps, and performance applications where factory fan setups prove inadequate. It provides precise thermal control without complex wiring or relay banks.
The controller operates via a 3/8 inch NPT threaded temperature sensor that screws directly into the engine block, coolant manifold, or radiator housing for real-time thermal monitoring. The adjustable activation range spans 150–240 degrees Fahrenheit, allowing users to customize fan engagement thresholds to match their cooling requirements and engine characteristics. Each of the two fan circuits can handle up to 35 amps independently, making it suitable for high-output electric fans.
Street rods, drag cars, off-road trucks, and restomod vehicles benefit most from dual-fan control, especially those running larger displacement engines or towing heavy loads in stop-and-go traffic. Installation requires mounting the control module in the engine bay or interior, ensuring easy access for adjustments. This product is a popular upgrade among hot rodders and automotive builders seeking enhanced cooling performance.
