In-line Fan Drive systems

Operators of mobile equipment and transport will often be looking to optimize performance, reduce noise levels and minimize emissions. This is best achieved with the aid of a system that can vary the dissipation of heat according to the effective operating requirements of the machine.

The FAN DRIVE is a smart system that controls the running speed of the heat exchanger fan. Decoupling the speed of the fan from the revolutions of the engine, it becomes possible to program the response of the system so as to optimize heat exchange and reduce noise. On receiving signals from sensors or from a CAN network, a programmable electronic control unit pilots an electric or electrohydraulic actuator to adjust the speed of the fan on the basis of the effective demand for cooling. The system can be equipped with a reverser for blowing the radiator core clean. Control options include electric, electrohydraulic open circuit, load sensing and closed circuit. The FAN DRIVE system is advantageous in that the engine no longer dictates the position of the fan: particularly important in situations where space is at a premium.
