BorgWarner has begun producing its electronically controlled Visctronic fan drives at its new plant in Itatiba City, Brazil.
By operating only when needed and precisely controlling the fan speed when engine cooling is required, this technology provides efficient engine cooling as well as improved fuel economy and reduced emissions for trucks, buses and off-highway applications. The fan also improves driver comfort by lowering noise, vibration and harshness, the supplier said.

Daniel Paterra, president and general manager, BorgWarner Thermal Systems, said: “Our new plant allows us to produce these advanced technologies for our customers locally, and our new engineering centre expands our network of technical centres, enhancing our local testing and validation capabilities.”
Rising exhaust gas recirculation rates and higher specific engine outputs are accelerating demand for more effective and efficient airflow solutions. Commercial vehicles, in particular, demand maximum cooling performance even at low driving speeds. Already proven in Europe, North America and Asia, the Visctronic fan drives use specially calibrated software to communicate with the engine’s electronic control unit, constantly responding directly to the engine’s cooling needs. By disengaging and rotating at minimum speed when no air cooling is needed, the technology reduces power consumption. When the engine requires more cooling, the fan drive automatically re-engages to provide efficient air cooling at the right time.
