ALMCO'S ultrasonic cleaning machine with agitated immersion feature provides greater cleaning power and is easy to operate. Available in two heavy-duty models, the machine moves a load of parts through 60 vertical 4-in. strokes per minute, while ultrasonic energy and surging action of the cleaning fluid removes dirt from cracks and crevices with ultimate efficiency. (A third, bench-top model, offers the ultrasonic technology, but not the agitation feature.) All three units offer continuous operation, a cleaning tank with insulated double-wall construction, an adjustable thermostat for fluid temperature, and Vibra-Bar transducer modules to guarantee no cracking, depolarization, or detachment from the radiating surface.
