In anticipation of the 2010 and Euro V emissions standards, Horton introduces a new line of viscous fan drives for heavy- and medium-duty applications, including off-highway equipment. Managed by the engine’s electronic control unit for precision fan speed control, the directly-controlled Stratis viscous fan drives are designed to cool higher-horsepower, hotter-running engines. They are equipped with an integral fan speed sensor that provides closed-loop control capabilities. An optimized magnetic design speeds reaction time for better modulation and cooling. In addition, an innovative reservoir, actuator and valve system combine to deliver a lower off-speed and faster response time for optimum cooling, reduced fan noise and increased fuel efficiency.
