Hydrostatic fan drive.
Bosch Rexroth Corp.
Bosch Rexroth's hydrostatic fan drive works in a wide range of ambient temperature conditions, from -40F to 212F. Incorporating the new Rexroth F I series pump and motor technology, the hydrostatic fan drives can be used in a variety of applications. Hydrostatic fan drives dissipate heat transferred by engine coolant as it flows through the radiator. The radiator's cooling performance is determined by the fan size, pitch of blades and fan speed. The hydrostatic fan drive features high flexibility with regard to the Layout of the entire fan system, it runs only when required, the maximum fan speed is not dependent on engine speed and more.
