Horton Inc. has introduced a fan drive conversion kit that it says saves fuel and reduces noise. The DM Advantage and DriveMaster Two-Speed Conversion Kit is designed to convert a DM Advantage or DriveMaster On/Off Fan Drive to two-speed technology to facilitate superior operating efficiency and performance. Two-speed technology is suitable for cooling refuse trucks, rear-engine cement mixers, school and city buses, fire trucks, severe-service vehicles and other on- and off-highway equipment with little to no air ram.
The two-speed conversion kit features advanced components and the latest magnet design for efficient and reliable operation, according to Horton; the conversion kit installs easily, without removing the fan drive from the engine, and is compatible with any 2.56-inch fan pilot. The company says the two-speed fan drive will have higher torque for turning larger fans and higher ratios, precise temperature control, quicker response to cooling needs, more available power to mount steep inclines, less wear and maintenance, higher reliability, less radiator abrasion from dust and debris, and faster engine warmups in cold weather.
In most operating conditions, the converted two-speed fan drive is powered by eddy current, which turns the fan at a lower speed; according to Horton, this reduces noise, saves fuel and increases available horsepower for auxiliary systems. When additional cooling is needed, the fan drive spring-actuates and runs the fan at full input speed, the company says.
