Viscous fan drives

  • 10-Jul-2008 07:54 EDT

Horton’s Stratis directly controlled viscous fan drives meet 2010 and Euro V emissions standards and are designed to cool higher-power, hotter-running engines. Suitable for heavy- and medium-duty applications, transit buses, motor coaches, and off-highway equipment, Stratis fan drives respond to cooling needs and are equipped with an integral fan speed sensor that provides closed-loop control capabilities. A magnetic design speeds reaction time for better modulation and cooling. In addition, the reservoir, actuator, and valve system combine to deliver a lower off-speed and improved response time for better cooling, reduced fan noise, and increased fuel efficiency. A rear-mounted cable harness shields the connection from fan blades. Maximum torque capability is 185 lb·ft (250 N·m).
