Intelligent Fan Drives: Cooling Only When Required

Rexroth's intelligent hydrostatic fan drives provide the necessary cooling performance for low-emission combustion irrespective of the air stream and engine speed. Rexroth has developed the complete system solutions especially for use in mobile machines such as wheel loaders, excavators, mobile cranes, dump trucks, combine harvesters, and buses. These vehicles make great demands on the cooling management system.
Rexroth therefore assists construction machine and vehicle manufacturers in meeting increasingly stringent exhaust and noise emission regulations. The adjustable control systems permit a reduction in fuel consumption of up to five percent.
The Rexroth system solutions feature a CAN-bus-enabled control unit, specially optimized for the fan drive, that evaluates all the important temperature parameters for coolant, oil, charge air, and exhaust gas recirculation and controls a variable axial piston pump/external gear motor combination. The compact, extremely high-performance hydraulic unit keeps the operating temperature within a very narrow temperature window in line with operating requirements so that the engines meet the legally allowable low emission levels.
