DuroSpeed fan driveBorgWarner says its new 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. The company claims the DuroSpeed fan drive reduces fan engagements for greater reliability and less noise in severe service applications.

The modular design uses the same clutch unit for all applications. Any Kysor on/off fan drive can be retrofitted to a DuroSpeed fan drive with a conversion kit consisting of only two add-on components, says the company.
