An automotive controller for Pierburg’s electric water pumps CWA50 / CWA100 / CWA150 / CWA200 / CWA400
... used by many OEM's such as BMW, Audi, VW, Porsche, Mercedes Benz ...
The Tecomotive “tinyCWA” 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
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)
- Simple to set up with only one rotary switch
- Choose your favorite target temperature in six steps from 15°C to 100°C (59°F to 212°F)
- LED display shows the current pump speed or rough coolant temperature
- Compact and robust anodized aluminum case
- Relay output for the radiator fan (recommend to use)
- Delayed shutdown of the pump and the fan after ignition turned off
- Manually control the pump speed (e.g. for bleeding or testing)
- LED warning system and various safety features
The CWA150 is basically the high pressure variant of the CWA100-3 we are also offering.
The dimensions and the weight are nearly the same.
New are the freshly designed impeller and impeller housing to accommodate for the higher differential pressures.
It is suitable for various systems in electrical vehicles and anything else that profits from that higher pressure capability.
