The Manual / Timed Recycle SPT-MM Slat Conveyor Sprayer is an asphalt release system for slat conveyors that applies chemical and recycles automatically, with a manual override. This system is designed for facilities that have no, low, or fluctuating water pressure. It uses a rugged 1/2" Sandpiper air-operated, double-diaphragm pump to draw water and chemical concentrate from user-supplied static containers and blend them "on-the-fly" using a metering manifold to achieve virtually any dilution ratio. When the adjustable recycle timer activates the system, solution flows to a spray bar suspended over the slat conveyor. In override mode, release agent is projected through a trigger gun and fan nozzle.
