BorgWarner Thermal Systems has announced a new series of fans, the “X” Series, which the company says offers better efficiency and enhanced performance for commercial vehicle and off-highway applications. The nine- and 11-blade polymer fans are designed to increase cooling capacity by as much as 4 degrees F at a 7 percent higher efficiency than current products.

The fans, termed XMD9 and XD11, have a hubless design with blade aerodynamics designed for heavy-duty cooling systems. The 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, according to the company.
