Magnetic EP-PD Asphalt Release Spray System

Model # 977894

The Magnetic EP-PD Asphalt Release Spray System is a magnetic sensor activated, time delayed, asphalt release applicator that mounts to a user-supplied drive-though arch for spraying asphalt truck beds. It is designed for facilities with low or no water pressure. This system uses an electric pump to draw ready-to-use chemical from a static tank. When a truck comes into range of the magnetic sensor, a delay timer allows the driver to position the truck under the spray nozzle before spraying begins and a run timer applies release agent for a pre-set time or until the vehicle leaves the spraying area, whichever is first.
