Products Less Emission, Lower Cost. Rexroth Hydrostatic Fan Drives The future of air movement lies with Rexroth hydrostatic fan drives Due to tightening of laws concerning emission and immission restrictions, the optimum design of the fan is becoming more and more important. Hydrostatic fan drives efficiently remove the dissipated heat ensuring optimum engine and combustion temperatures and therefore help to meet emissions regulations. In addition, controlled by highly sophisticated sensors, the cooling performance is strictly linked to the measured temperatures. Compared to continuous fan operation, this saves valuable energy and fuel costs. Advantages at a glance: High flexibility with regard to the layout of the entire fan system Fan runs only when required Maximum fan speed is not dependent on engine speed Engine temperature is precisely controlled Low hysteresis Minimal loss of hydraulic energy Reduction in fuel consumption (up to 5%), waste gases and noise emissions Gear motor offers compact design with integrated proportional control Robust gear motor/pump design results in high reliability and efficiency Rexroth hydrostatic fan drives can be used in a variety of applications including construction machines, agriculture and forestry vehicles, and road and rail vehicles. Our specialists assemble solutions tailored to your requirements using a whole range of axial piston pumps and motors, external gear pumps and motors, thermal relief valves and electronic controls.
