JST DT921E Heated Ultrasonic Cleaner 18x18 Allen-Bradley PanelView 550 NEY

JST DT921E Heated Ultrasonic Cleaner 18x18 Allen-Bradley PanelView 550 NEY Sweepsonik

The JST DT921E is a fully automated, heated industrial ultrasonic cleaning system built by JST Custom Fabrication of Boise, Idaho. Designed for precision cleaning of flat plates and similar substrates, the system integrates ultrasonic agitation, heated fluid, filtration, pneumatic control, and programmable HMI operation into a single stainless steel floor unit. The cleaning chamber measures 18" x 18" x 19" (interior) and accepts multiple plate sizes simultaneously via built-in plate rack holders.

Applications

Automated heated ultrasonic cleaning systems like the JST DT921E are used in precision industrial and semiconductor cleaning processes where consistent, repeatable results are required. The combination of ultrasonic agitation (via the NEY Sweepsonik generator), heated fluid, filtration, and programmable PLC/HMI control makes this class of equipment standard in photomask cleaning, flat panel substrate cleaning, precision optical component cleaning, and electronics manufacturing. The plate holder configuration — accommodating up to twenty flat plates in two size ranges — is particularly suited to batch cleaning of photomasks, reticles, metal plates, or similar flat substrates. Programmable Allen-Bradley PanelView HMI controls allow operators to set and recall cleaning parameters including time, temperature, and process sequencing. Systems of this type are found in semiconductor fabs, flat panel display manufacturing, precision optics shops, and advanced electronics assembly environments. The integrated Filterite filtration and Dwyer flow metering allow for controlled fluid management and recirculation throughout the cleaning cycle.
