Fan Drive Systems

New emission regulations have increased the heat rejection needs of diesel engines and tightened the engine operating temperature range necessary to meet allowable diesel exhaust limits. A hydraulic modulating fan drive system allows the machine designer to keep engine temperature in a narrow operating band and saves engine power and fuel for the majority of operating conditions.

Off-highway mobile machinery OEMs and distributors can choose from 6 types of pre-engineered hydraulic integrated circuits (HICs) designed to provide speed control and reversing for hydraulic modulating fan drive motors in open circuit hydraulic fan drive systems.
