The Cleanfix
In addition to the reversing function of the CLEANFIX SC fan series for cooling and cleaning, this fan series offers variable blade pitch control. This change in blade angle corresponds to the cooling requirements of the machine. All this is achieved by the CLEANFIX fan itself, without intervention from the engine electronics.The CLEANFIX VP series offers the further benefits of a quieter vehicle operation, increased fuel savings, and reduced fan horse power consumption of up to 60%.
During initial operation (when the engine is cool), the blade pitch is at its lowest angle resulting in an economical (ECO) cooling mode. As the temperature begins to rise, the thermal actuators expand to move the blades to a steeper position creating higher airflow performance. At high temperatures, the blade angle increases to its maximum pitch (POWER). Then as the engine and hydraulics cool, the thermal elements contract and the blades return to the most economical position.
