The Horton fan clutch is a variable-speed, closed-loop, fluid-filled drive that helps efficiently control the cooling fan from the engine’s RPM. The variable-speed fan drive sends engine data directly from the ECM to read real-time data and adjust the fan speed only as needed. Completely sealed and air cooled to eliminate the need for additional hoses or oil, this clutch can help reduce contamination caused by engine oil leaks. The fan is composed of a special thermoset composite material, the highest strength-to-weight ratio among all materials currently used in fans.
* Fuel savings and other benefits are dependent upon mine profile and certain environmental factors, including (but not limited to) idle time, ambient temperature, altitude, coasting time, haul cycle, truck-limited vs. shovel-limited operations, average engine load factor (% time at full load), engine age and individual operator. Certain benefit results are based solely from bench-testing by Horton. Komatsu does not guarantee that you will see the same results.
