Revotec Adjustable Thermocontact Kit, Ø32 mm, y for 12V 30A fan

The Revotec Ø32 mm adjustable thermocontact kit for 12V electric fans automatically manages engine cooling by controlling fan activation based on cooling fluid temperature. Installed directly on the upper radiator hose, it is suitable for cars, race cars, 4x4s, and SSVs equipped with an electric fan.

The activation temperature is adjustable from 70 to 120°C, allowing the fan’s operation to be adapted to the engine’s needs and the configuration of the cooling system. When the selected temperature is reached, the fan automatically turns on and then shuts off when the cooling fluid temperature drops 3°C below the selected threshold.

This Revotec electronic fan controller directly measures coolant temperature at the hose. It offers a practical solution for adding an electric fan to a vehicle, replacing an existing control unit, or building a custom cooling system without having to install a remote temperature sensor.

Made of aluminum, the controller fits directly into the upper hose. The complete kit includes a 700 mm wiring harness, a 30A relay, hose clamps, and all necessary mounting accessories. Mounting instructions are also available on this page.

Designed for a 12V power supply on vehicles with a negative ground, the system uses a 30A relay. The maximum current of the electric fan connected to the controller must therefore not exceed 30A.

Check the diameter before ordering: the Ø32 mm dimension corresponds to the outer diameter of the Revotec controller and thus to the inner diameter of the hose that attaches to it. Measure the inner diameter of your upper radiator hose to select the appropriate thermocontact.
