DART™ AP-MM Asphalt Release Spray System
Model # 977801
Overview
The DART™ AP-MM Spray System is a push button 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" to create an accurately diluted solution. The driver pushes the button to activate the system; a delay timer allows the driver to position the truck under the nozzle before spraying begins and a run timer prevents overuse of the release agent.

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 push button activated, adjustable, single-shot timer will delay for up to 60 seconds, allowing the driver to get in position, and then apply chemical for up to 60 seconds before shutting off
  • 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
  • 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
