BorgWarner Thermal Systems claims its new “X” Series of engine fans offer better efficiency and cooling performance for commercial vehicles and off-highway applications
BorgWarner Thermal Systems claims its new “X” Series of engine fans offer better efficiency and cooling performance for commercial vehicles and off-highway applications.
Carl Roberts, director of engineering, said the new nine- and eleven-blade polymer fans on the X Series models can increase cooling capacity by as much as 4º F at a 7% higher efficiency than current products.
The XMD9 and XD11 fans feature nine and eleven fan blades, respectively, offer a hub-less design with blade aerodynamics designed for heavy-duty cooling systems, said Roberts. He added that fans have been optimized for performance and packaging compatibility with the BorgWarner family of heavy-duty fan drives, and meet the cooling performance required for U.S. 2007 and Euro 5 engines.
