Scaletron Industries Ltd. introduces the VMF-90F volumetric feeder, a totally self-contained, automated, dry-chemical addition system. Full-featured upon installation, it also offers useful options to optimize automatic monitored dosing processes in the water and wastewater industries. The entire system is mounted on a steel skid with forklift cutouts. The feed rate is 0.36 to 3.56 cubic feet per hour, with accuracy to within one percent of volume. The feed rate is optimized with a 1.5-inch (38.1-mm) diameter, stainless steel open helix feed screw, which delivers material to a built-in wetting cone. The standard VMF-90F unit features carbon steel construction with corrosion-resistant zinc oxide primed, dry-powder epoxy coating.
