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 Charged Air Cooler Fans 1 3 Shared Fans 6 8 Engine Coolant Fans 5 7 CAC Radiator

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%

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

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. Curb Side Quite RPM

Fan Speeds and Full Load Cooling % Time On Off 19.3% 750 RPM 30.6% 1813 RPM 27.1% 2875 RPM 20.5% 3938 RPM 2.0% 5000 RPM 0.7% 5500 RPM 0.0% 99% of the time, cooling system demand is less than 125 amps 97% of the time, cooling system demand is less than 71 amps 76% of the time, cooling system demand is less than 34 amps 49% of the time, cooling system demand is less than 15 amps

Safety, Maintenance, Diagnostics Mini-Hybrid reduces thermal events by eliminating the hydraulic fan system. Maintenance is easy with manual reverse feature. Also, MH8 comes with both a diagnostic light and service technician tool. Reversal Push Button Diagnostics LED
