The BorgWarner DuroSpeed 2-speed fan drive is specifically designed to deliver reliable cooling for severe operating and vocational truck applications, such as construction vehicles and municipal trucks. According to the company, BorgWarner’s DuroSpeed fan drive significantly reduces fan engagements for greater reliability and less noise in severe service applications. The modular design allows any BorgWarner Kysor on/off fan drive to be easily converted to a DuroSpeed fan drive. BorgWarner’s pneumatically-actuated DuroSpeed 2-speed fan drive is designed with a higher disengaged fan speed to prevent engine temperatures from rising too quickly. To reduce complexity and minimize upgrade costs, BorgWarner’s modular design uses the same clutch unit for all applications.
