Horton says its new higher-torque EC600 electromagnetic on/off fan drive is designed for use on medium-duty trucks,
as well as buses and off-highway equipment. It features 1500 in.-lb (170 Nm) dynamic out-of-box torque, compared
to 850 in. lb (96 Nm) in the company’s EC450 model.

The EC600 engages only when needed, of course, typically about 10% of the time. Precise engine-temperature control,
says Horton, ensures that the vehicle operates at maximum fuel efficiency and horsepower and can haul heavier loads
or scale steeper grades with minimal drag. Other benefits include faster engine warming, more heat to passenger and
drive compartments, and improved air conditioning.

The EC600 Electromagnetic On/Off Fan Drive requires minimal installation time and features zero lifetime
maintenance, the maker claims. Current applications for the product include Freightliner, Peterbilt, and Kenworth
trucks.
