Horton has introduced Arctis Two-Speed Fan Drives, which it says offer better, more efficient engine cooling for medium-duty trucks, buses, severe-service vehicles, rear-engine cement mixers and other on- and off-highway equipment with little to no ram air.


The Arctis line provides the highest torque available from Horton, 2,700 inch-pounds (305 N-m), in its patented two-speed technology.

In most conditions, the two-speed fan drive is powered by eddy current, turning the fan at a lower speed, reducing operating noise and increasing available horsepower for auxiliary systems. When the vehicle needs more cooling, the fan drive springs actuate to run the fan at full input speed.

Because the eddy current mode provides sufficient cooling most operating conditions, full-speed fan operation is reduced by 85 percent. This improves fuel economy, reduces operating noise and increases available horsepower. Fewer fan engagement cycles also improve fan drive, belt and tensioner reliability while minimizing radiator abrasion from dust and debris.
