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.

Fuel Consumption
Fuel Savings
- MARTA Study 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.

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!

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.

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.
