2-Way Magnetic AP-MT Asphalt Release Spray System

Model # 977899

The 2-Way Magnetic AP-MT Asphalt Release Spray System is a magnetic sensor activated asphalt release sprayer for diluting chemical concentrate "on-the-fly" using metering tips and for coating any length asphalt truck bed with asphalt release agent. 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 spray nozzle before applying release agent. When the vehicle leaves the spraying area, or time expires, the system shuts down and resets. Switch between different concentrations or chemicals with ball valves at the control box.


Key Features

  • The driver remains in his cab and avoids the risk of slip-and-fall injury and chemical waste
  • Designed to spray asphalt release chemicals on to truck beds from a nozzle that attaches to an existing drive-through spray bar
  • Switch between 2 different concentrations or chemicals using ball valves at the control box
  • The rugged Sandpiper pump draws chemical concentrate and water from static tanks and blends them "on-the-fly"
  • Achieves a wide range of dilution ratios using a metering manifold
  • An adjustable timer delays spraying to allow the driver to position the truck
  • Evenly coats the truck bed in just seconds, reducing run-off and chemical waste
  • Spraying stops when the driver leaves the area or time expires
  • Chemical resistant wetted components ensure years of outstanding performance with minimal maintenance
