Hydrostatic Fan Drive
Used in material-handling systems,
construction machinery, buses,
HGV and passenger cars with proportional
closed loop speed control.
Consists of the following parts:
- External gear motor with proportional
pressure relief valve
- Single or multi-channel electronics
- Temperature sensors for fluids
and air
Gear motor with proportional pressure relief valve
- For fan powers up to 20 kW
- Proportional fan speed control
- Failsafe behavior in event of power
failure
- Low hydraulic energy losses
- Precise coolant temperature control
