The RADAR™ EP-LM Spray System is an electric eye activated, asphalt release applicator that mounts to a user-supplied drive-though arch for spraying asphalt truck beds. This system uses an electric pump to draw ready-to-use chemical solution from the included 7 Gallon Level Master™ tank which maintains a constant supply of solution. When a truck breaks the electric eye's line-of-sight, 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.
