7. How Does It Work?
Mini-Hybrid (MH8) is an electric only fan system that replaces traditional mechanical fan. MH8 is electronically controlled to cool both charged air and engine coolant separately. MH8 is independent of engine speed and control - capable provide full load cooling at engine idle. 2 4

8. Fuel Consumption - MARTA Study -
Fuel Savings
MH8 provides more fuel savings throughout the engine rpm range. Typical fuel economy ranges from 3% to 10% based on duty cycle, climate, and engine type. 7%
Fuel Savings 3%

9. Power to the Wheels!
Put the power where you need it, at the wheels. MH8 provides up to an additional 50 HP at the wheel. At the second speed setting of (1800 rpm) of the MH8 kit has less parasitic loss than the mechanical fan turned off!
Power Savings

10. Noise and Weight Advantages
The Mini-Hybrid fans run under 2000 rpm the majority of the time. At this level, the cooling system produces only an additional 2 dBA over fan off mode. With the removal of the hydraulic pump, fluid, fan, etc., MH8 is a 300 lb weight savings over the conventional cooling system.
