Two-Speed Fan Drive  - HORTON EUROPE GMBH & CO. KG


Two-Speed Fan Drives Less noise. Exceptional efficiency. Arctis Two-Speed Fan Drives offer a better, more efficient cooling solution for on- and off-highway vehicles without ram air. Rigorously tested, Arctis Two-Speed Fan Drives are engineered for reliability and long operating life in the highest-heat under-hood conditions. The Arctis Two-Speed alternates between eddy current and spring-actuated cooling for precise, highly efficient temperature control and superior horsepower performance. Under most operating conditions, the Arctis Two-Speed Fan Drives are powered by eddy current—turning the fan at a lower speed. This reduces operating noise, increases available horsepower for auxiliary systems, and minimizes radiator abrasion from dust and debris. When additional cooling is needed, the Arctis Two-Speed spring actuates and runs the fan at full input speed. Benefits - 80% reduction in fan engagement cycles for improved fan drive, belt and tensioner reliability - 85% reduction in full-speed operation for better fuel economy - Reduced operating noise - Increased available horsepower - Precision engine temperature control - Quick response to cooling needs - More efficient cooling - Less slip at engagement for longer friction liner life - Increased reliability - Easy installation and maintenance - Faster engine warm-ups in cold weathe - Reduced radiator clogging and abrasion Features - Highest torque to date—2,700 in.-lbs. [305 N-m] - Larger air chamber for full disengagement - Ability to drive larger fans at higher ratios - Superior bearing technology for maximum reliability - Pneumatic control - Simple control via solenoid valve Applications - Medium-duty trucks - Buses - Severe-service vehicles - Rear-engine cement mixers - Other on- and off-highway equipment with little to no ram air Specifications Related Products - DM Advantage Two-Speed Fan Drives - PolarForce Two-Speed Conversion Kits - WindMaster Fans Links - Order or View Literature - On-line Catalog
