Single Fan Controller Preset 180 Degrees

The Single Fan Controller Preset 180 Degrees by DERALE is a precision engine cooling management system engineered for vehicles requiring automatic fan activation at specific temperature thresholds. This push-button temperature sensor controller is ideal for hot rod builders, classic car enthusiasts, and performance vehicle owners seeking reliable fan engagement without constant manual adjustment. By automating cooling fan operation, this controller prevents engine overheating while optimizing fuel efficiency and reducing unnecessary cooling load during normal driving conditions.

Built with DERALE's proven dual-range design, the controller engages the cooling fan at exactly 180 degrees Fahrenheit and disengages at 165 degrees, providing a tight 15-degree hysteresis band for stable operation. The push-in temperature sensor delivers accurate thermal feedback directly from the engine coolant system, while the robust 25-amp relay handles substantial electrical demands without switching hesitation. Compact dimensions of 4.4 x 2.3 x 7.3 inches allow flexible mounting in engine compartments with limited space, and the included bushing and harness assembly simplifies installation into most universal cooling systems.

This controller benefits street rod builders, vintage car restorers, and weekend racers who demand repeatable cooling performance without electronic modules or computer integration. The preset 180-degree activation point suits naturally aspirated engines and modest boost applications where consistent coolant temperature management is essential. Installation requires basic wiring knowledge and works with single electric cooling fans in bracket or shroud configurations; compatibility should be verified with your specific fan motor amperage rating against the 25-amp relay capacity for safe, long-term operation.
