Individual temperature setting for tire heated blankets

With the TCU-4 × 1 control unit, individual temperatures of up to 120 ° C can be set for each tire.


Wear-free, fully electronic power electronics. Exact correspondence between the displayed and the actual tire temperature.

Temperatures can be set individually for each tire in 0.1 ° C steps. By default, we limit the setting to 120 ° C, this limit can be shifted if desired. In Formula 1, our heated tire blankets were used to heat temperatures up to 140 ° C, but as a rule it makes sense to limit it to 120 ° C. The high / low switch can be used to preset 2 temperature levels and then, if necessary, to select them by flipping the switch .

The illuminated displays are easy to read even in difficult lighting conditions. Additional LEDs are located next to the displays to control the heating function.

The made-to-measure ABS housing ensures good protection of the displays, switches and LEDs thanks to the corresponding indentations. The aluminum rear wall also serves to dissipate heat from the power electronics. Splash-proof ventilation slots on the sides at the top and bottom ensure a healthy temperature balance inside the device.

On the underside of the housing, the 4 lines to the 4 tire heating blankets are led out through stable cable guides. The cables (approx. 1.8m) are color-coded to enable easy assignment to the respective tire. The 230V power supply of the TCU4x1 takes place via an approx. 2m long mains cable with a Schuko plug.
