Davies Craig Digital Thermatic Fan Switch Kits

Davies Craig digital thermatic fan switch kits sense air temperature as it passes through the radiator with the sensor placed in the fin section. The sensor can also now be placed directly into the coolant system—in combination with a temperature sensor adapter kit. These fan switch assemblies are compatible with 12 or 24 V applications, and feature an adjustable range of 40 to 110 C, or 104 to 230 degrees F. Temperature is set by pressing the set button, and the units can run one or two fans. The second fan (if applicable) will start 10 seconds after the first fan begins cooling. Davies Craig switch kits operate thermally and also when the air conditioning being used.
