Variable Speed Engine Cooling Fan

Variable pitch engine cooling hub.

Variable speed engine cooling fan.

The flex a lite variable speed control module is an adjustable fan controller that can be set to have your fans come on at any temperature between 160 240f. All joints are sealed with high quality o rings. The flex a lite variable speed controller turns the electric fan on and off at the desired temperature. Maintaining a consistent engine temperature is a more efficient way to keep your engine cool.

Derale performance is changing the rules of engine temperature control with smart technology brought to your car s cooling system through derale s patented pwm fan controller. Engine cooling fan issues. The advantage of a variable speed engine cooling fan is that the engine is better able to control its operating temperature under varying conditions. This can lead to amperage spikes excessive fan wear and plenty of undesired fan noise.

Flexxaire s in motion variable pitch hub allows the fan blade pitch to be adjusted at any fan speed. You can easily adjust the activation temperature between approximately 160 240 degrees fahrenheit. Fans turn on at 60 percent power and fan speed increases as the temperature rises. When fans come on with temperature they are activated at 60 run using a soft start feature which greatly reduces startup amperage.

All hub components are machined from solid material to ensure perfect balance without any voids or porosity in material structure. Development of a continuously variable speed viscous fan clutch for engine cooling system 980838 this paper presents a discussion of the development of a viscous fan clutch with continuous linear variable speed control function for engine cooling system to reduce cooling fan noise and improve the overall fuel efficiency of the engine. Because it can allow the engine to overheat. On applications that have variable fan speeds.

Or a failure of the fan relay or control circuit is bad news. The engine may also overheat if fan speed fails to increase when additional cooling is needed. Historically cooling fans run at 100 even when less airflow is needed constantly turning on and off as the engine temperature changes. Many other fan controllers turn the fan on when the engine is getting too hot and turn off after expending a lot of energy cooling it.
