Enables emissions reduction
Appropr iate Cool ing at any engine RPM
Why Hydraulic Fan Drives?
3 main reasons
Efficiency.
70-90% Efficient. Frees up Horsepower to do work
Fuel savings. High Power to Weight Ratio.
Design advantages
Often uti lizes existing hydraulic system
Reversible - Clear clogged radiators
Installation Flexibility: Small Size, Locate anywhere
Fixed tip Clearance = 10-15% more cooling efficiency

This Fan System is still in Development Target customer is the Transit Authority, bus refurbisher, repower facility
NOT OEMs
TAs look for Fuel savings, reduction in maintenance, etc.
Now with Parker Olaer as a solution, Parker canbe able to provide a full solution
Olaer oil coolers
In the short term they can supply oil coolers to the truck markets.
Can be used for smaller radiators for hybrid trucks, smaller vehicles.
If you believe you have a potential opportunity, talk to Pat Berkner to discuss.

Sizing & Specification
Questions To Ask
-
8/13/2019 Fan Drive Training
32/42
Pump and Motor Sizing Questions:
Maximum fan speed needed?
Lowest pump rpm need to achieve the maximum fan speed?
Rated power of the fan at its rated speed?
Maximum power or torque available to drive the pump?
Minimum and maximum engine speed?
Maximum allowable or desired hydraulic pressure?
Other Clarifying Questions:
Thrust, axial and dynamic loads on the fan motor?
What features are needed {reversing, speed control, etc}?
Duty cycle of the fan?
Mounting, shaft and porting on the pump and motor?
Space restrictions?
Questions To Ask
32
Additional Factors:
-
8/13/2019 Fan Drive Training
33/42
To Accurately Calculate the Fan / Hydraulic Performance it is very important to:-
1. Account for Pump & Motor Efficiencies over the speed and temperature range.
2. Consider total hydraulic losses (hoses, valves).
3. Address Dynamic Forces on the motor:
Additional Factors:
Dynamic Load
X Axis
