Modular Clēr™-FCU (Fluid Control Unit)
The Clēr™ FCU can be configured with as few as three independently controlled cleaning zones for today’s ADS features. Its modular design facilitates expansion for more complex AV designs. The modular and flexible design offers custom connection configurations, analog VDC or CAN/LIN capable controls, and easy engineering integration. Optimized pressure drop can be maintained for flow rates up to 1.7 LPM of washer fluid through a single valve, allowing optimal cleaning of sensor zones for up to five LIDAR cleaning nozzles. Optical sensor availability can be restored to a safe and functional level in less than one second using the advanced cleaning system.
For many applications, the cleaning process with liquid can be followed by a drying process with compressed air.
