RADAR™ Magnetic AP-MM Spray System

Model # 977845

The RADAR™ Magnetic AP-MM Spray System is a magnetic sensor activated, time delayed, asphalt release applicator that mounts to a user-supplied drive-through arch for spraying asphalt truck beds. This system uses a rugged Sandpiper air-operated, double-diaphragm pump to draw chemical concentrate and water from separate static tanks and blend them "on-the-fly" through an adjustable metering manifold to create a diluted solution. When a truck comes into range of the magnetic sensor, the system activates and a delay timer allows the driver to position the truck under the nozzle before spraying begins. The system shuts down and resets at the end of a pre-set time period or when the vehicle leaves the spraying area.

Key Features
