Visctronic fan drives utilize BorgWarner’s proven viscous technology with precise electronic control. The fan drive is controlled by the engine’s control module for precise fan speed modulation. Visctronic fan drives provide better engine cooling and improved fuel economy with minimum parasitic loss. The Visctronic fan drive’s ability to better control engine temperature effectively provides the cooling needed for low emission requirements. Also, lower average fan speed and horsepower draw during cooling results in reduced noise, greater economy, and improved driver comfort. All of which make it an ideal choice for commercial vehicles, light trucks and off-highway products around the world.
