The Tecomotive “tinyCWA400” is able to control all CWA type electric water pumps (eWP) in the appropriate manner.
It is suitable for cars or any other thing where smart cooling is required.

When activated the controller is measuring the current coolant temperature and the rate of increase with the connected
temperature sensor.
With this data it then calculates the appropriate water flow and sends a signal to the pump where the internal pump electronics then set it to the right speed. This way you will always have the right pump speed for any circumstances.

We developed this product with very special attention to quality, operational safety, ease of use and a very nice appearance.
The compact and anodized aluminum case measures only 44x44x12mm. (1.7x1.7x1/2inches)
