FAN CONTROLLERS
NEW! Variable Speed Fan Controller with Digital Display
Maintaining a consistent engine temperature is a more efficient way to keep your engine cool. 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. This can lead to amperage spikes, excessive fan wear, and plenty of undesired fan noise. These problems can all be reduced substantially with PROFORM's new variable speed controller. This variable speed fan controller makes the fan or fans run at whatever speed is needed to maintain a consistent temperature. The controller receives a temperature signal from the radiator with either a push-in, or thread-in brass probe. The fan controller processes this signal and runs the fan(s) at the correct speed needed to maintain the desired temperature. The weather resistant billet aluminum housing with bright digital display ensures easy setting by simply pushing + or - to set the temperature. By simply pressing the Mode button, the digital display will show temperature in F° & C°,as well as the amperage being used by the fan(s). The controller can accommodate one or two 12v volt brushed motor fans. To substantially reduce amperage spikes, the controller soft starts the fan(s) by slowly ramping up to the required speed. Mounting hardware, and necessary electrical connections included. Adjustable Electric Fan Controllers
PROFORM’s premium adjustable fan controllers make adding a thermostat to your cooling system easy. Fan activation is adjustable between 150 and 240 degrees F. These fan controllers are recommended for race and street applications.
