RADAR™ AP-MM Spray System

Model # 977841

The RADAR™ AP-MM Spray System is an electric eye (photocell sensor) activated, time delayed, asphalt release applicator that mounts to a user-supplied drive-though 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" to create an accurately diluted solution. When a truck breaks the electric eye's line-of-sight, a delay timer allows the driver to position the truck under the nozzle before spraying begins and a run timer limits application to a pre-set time period or until the vehicle leaves the spraying area, whichever is first.

Key Features
  • Designed to spray asphalt release chemicals on to truck beds from a nozzle that attaches to an existing drive-through spray bar
  • The rugged Sandpiper AODD pump draws chemical concentrate and water from separate static tanks and blends them "on-the-fly"
  • The system delays for an adjustable length of time when a truck breaks the beam of the electric eye, allowing the driver to position the truck, before activating for an adjustable, pre-set length of time
  • The driver remains in his cab and avoids the risk of slip-and-fall injury and chemical waste
  • Evenly coats the truck bed in just seconds, reducing run-off and chemical waste
  • Spraying will stop if the driver leaves the area early
  • A float valve assembly attaches to, and automatically refills, a user-supplied static water tank
  • Achieves a range of dilution ratios using a metering manifold to control chemical and water flow
  • Chemical resistant wetted components ensure years of outstanding performance with minimal maintenance
  • Available with a magnetic sensor (#977845)
  • Available as a foam applicator (#977930)
