By regulating light-duty engine variable speed fans based on heat rejection demands and ambient temperature, consistent power savings over the entire operating spectrum can be achieved.

Optimizing fan control strategies enables engineers to achieve a machine performance greater than expected from limited power sources. Additional power savings are available by controlling the fan in response to transient power demands, as well as effective integration of hydraulics and electronic control strategies.

Achieving maximum useful work from a limited power source is a step that should be addressed early in the planning strategy for the machine designer. This requires a thorough understanding of the application by the system integrator, including communication with the end user to define their expectations.
