eFan Micro Hybrid Systems

AVID’s eFan Micro Hybrid System (MHS) replaces the conventional engine cooling system. The AVID MHS reduces parasitic loads on the engine and allows operating temperature to be optimised and reduces fuel consumption.

Description

AVID has pioneered the development of the eFan Micro Hybrid System for heavy duty vehicles. This system brings cost effective electrification of the cooling system to reduce parasitic losses on the engine and improve thermal management. Reducing fuel consumption by up to 15% with a corresponding reduction greenhouse gas and toxic exhaust emissions. In conjunction with the eFan Micro Hybrid System the vehicle electrical system can be upgraded with a Power Series Alternator.

 

In addition to saving fuel the system also provides additional benefits to the vehicle operator. The electric fans have a reversal switch which can clear trapped debris out of the heat exchangers. This means that the cooling pack can be kept much cleaner which not only leads to a reduction in overheating but also increases the life of the heat exchanger.

The risk of damaging the heat exchangers during cleaning is also greatly reduced. Optimising the engine operating temperatures can also reduce component wear and tear and extend MTBF for major units.

Improved engine thermal management means improved operation of exhaust after-treatment systems. Improving real world performance of these systems by ensuring the engine reaches its optimum operating temperature faster and stays there, unlike the conventional systems which often result in poor temperature control and low temperature operation of the engine.

The system also addresses some of the major operational issues associated with operating heavy vehicles such as buses and earth moving machinery. For example, breakdowns due to overheating, excessive time spent on cooling system maintenance, vehicle fires are caused and accelerated by leaking fan drive hydraulic systems and low temperature operating cycles on heavy diesel engines.

Only the AVID eFan MHS uses our ultra high performance electric fans, our advanced electronic controller and specially designed heat exchangers to create a highly efficient thermal management system. Find out more about how our heat exchangers improve reliability here:
