Horton has introduced a fan drive conversion kit that saves fuel and reduces noise. The new DM Advantage and DriveMaster two-speed conversion kit converts a DM Advantage or DriveMaster on/off fan drive to two-speed technology.

Two-speed technology is designed 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 kit features advanced components and the latest magnet design for efficient and reliable operation and installs easily, without removing the fan drive from the engine, and is compatible with any 2.56-inch (65 mm) fan pilot. 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 warm-ups 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. 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.
