Horton Inc. says it designed its DM Advantage fan drives to meet current and future industry demands for reliable engine cooling, fuel savings and noise reduction. Offered in on/off and two-speed technologies, DM Advantage fan drives are engineered for the highest-heat underhood applications. The fan drives are comprised of premium bearings, a superior air cartridge and a long-wearing friction liner, yielding better engine performance and longer operating life, according to the company.
The spring-engaged on/off fan drive is designed to keep engine coolant at a more consistent operating temperature and for increased reliability in high-horsepower applications, Horton says; it features high torque for turning larger fans, a lighter weight and low parts count for simplicity.
The two-speed fan drive alternates between eddy current and spring-actuated cooling to facilitate precise, highly efficient temperature control and faster engine warmups in cold weather; it is suited for vehicles with little or no ram air. While using eddy current, it turns the fan at a lower speed, which reduces operating noise, increases available horsepower for auxiliary systems and minimizes radiator abrasion from dust and debris, according to the company; when additional cooling is needed, it spring-actuates and runs the fan at full input speed.
