Selecting a cooling system’s fan drive is a major challenge for machine or system designers. Of the many factors to consider for this decision, whether a fan reversing function is required is one of the most significant. If reversing is required, a hydraulic fan drive is a top choice. This paper describes several of the basic systems currently in use for reversing fans as well as a newly optimized option seldom used in the past that is now more relevant due to a recent product development. |
