Finally there is a better, more efficient alternative for cooling on- and off-highway vehicles without ram air. Only from Horton—a world leader in fan drive technology—the DriveMaster Two-Speed Fan Drive alternates between eddy current and spring actuated cooling for precise, highly-efficient temperature control and reduced operating noise levels.
Under most operating conditions, the DriveMaster Two-Speed Fan Drive is powered by eddy current. This turns the fan at a lower speed, which reduces operating noise, increases available horsepower for auxillary systems and minimizes radiator abrasion from dust and debris. When additional cooling is needed, the DriveMaster Two-Speed spring actuates and runs the fan at full input speed. By supplying additional engine cooling only when it’s needed, the DriveMaster Two-Speed delivers superior horsepower performance. Less noise. More power. Increased efficiency. Upgrade your vehicles’ performance today by specifying the DriveMaster Two-Speed Fan Drive.
