Horton has released a new two-speed fan drive 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 of fan drives provides the highest available torque from Horton, 2,700 in-lbs. (305 N-m). Under most operating conditions, the fan drive is powered by eddy current, turning the fan at a lower speed to reduce operating noise and increase horsepower for auxiliary systems. The reduced speed, as much as 85%, improves fuel economy in addition to the reduction of noise and horsepower improvement.
Arctis fan drives feature a high-torque clutch pack to drive larger fans at higher rations and a larger air chamber for full disengagement.
