BorgWarner announced it has achieved exclusive status as a supplier of fans and fan drives for Freightliner’s new Cascadia truck, its most popular over-the-road truck. BorgWarner technology is now the only available option on 2017 Detroit DD13, DD15 and DD16 engines as well as the 2017 Cummins ISX15.
“BorgWarner engineers thoroughly understand the operating conditions for on-highway vehicles. The combination of our six-blade fan and proven on/off fan drive delivers benchmark efficiency and noise reduction,” said Joe Fadool, President and General Manager, BorgWarner Emissions & Thermal Systems. “Trucking fleets will appreciate improved fuel economy as well as its modular, low-maintenance design.”
Many Class 8 trucks use fans with as many as 11 blades, BorgWarner said, and when the fan is disengaged, blades can restrict airflow through the radiator. Using its proprietary design tools, BorgWarner designed a six-blade fan with optimized blade geometry that the company said delivers effective cooling when the fan drive is engaged and allows greater airflow when it is disengaged.
The system also incorporates a modular design for easier maintenance, the company said. The removable friction liner can be replaced while the fan drive is still mounted to the truck and the clutch unit can be replaced without removing the hub assembly, BorgWarner said.
