There are times when a fan is not needed: The standstill option
With the optional standstill feature, the fan rotor is completely shut down during the start-up phase or when ambient temperatures are very low. Thus the internal combustion engine reaches its operating temperature faster and the exhaust gas pollutants are optimally reduced. Moreover, the consumption-optimized standstill feature permits fuel savings of up to 1 percent compared to conventional fan standstill solutions.

Blowing the air the other way: The reversing operation
Temperatures are just one problem. The second problem are dust and dirt, which deposit themselves inside the radiator, especially in the case of construction and agricultural machines. To prevent the cooling performance from deteriorating, engineers have come with a smart solution – the reversing operation. The fan rotor direction of rotation is changed at defined intervals, so that air is blown in the opposite direction, carrying the dirt outside. The advantage of the reversing operation is obvious. The radiator remains unobstructed and the engine operates at ideal engine and combustion temperatures.
