Ultrasonic Cleaner (Digital) – ToronUC™ DG Series
ToronUC™ DG Series Digital Ultrasonic Cleaner is a full-featured, digitally controlled benchtop ultrasonic cleaning system combining an LED digital display, degas function, power-off memory, and a sound-dampening lid into a single robust stainless steel platform. Available in seven tank sizes from 2 to 27 liters, the DG Series is designed for professional laboratory, medical, optical, dental, jewelry, and light industrial ultrasonic cleaning applications where digital precision and operational convenience are essential.
The DG Series is distinguished by its sound-proof lid with integrated SUS304 stainless steel cleaning basket, which significantly reduces the operational noise level during the ultrasonic cleaning cycle an important feature for customer-facing retail environments, dental reception areas, optical stores, and open-plan laboratory settings where excessive noise is unacceptable. The digital panel provides independent control of heating, degas function, timer, and ultrasonic power with a power-off memory function that restores the last-used settings on startup.
Equipped with LED temperature and timer displays, a 1–99 minute adjustable timer, 20–80°C temperature range, drain tap and cooling fan on 6L and above models, and 304 stainless steel basket included as standard, the ToronUC™ DG Series is a complete, out-of-the-box digital ultrasonic cleaning solution. It excels as a dental ultrasonic cleaner, ultrasonic jewelry cleaner, ultrasonic glasses cleaner, industrial ultrasonic cleaner, and ultrasonic carburetor cleaner platform across North American professional and industrial markets.

Theory & Ultrasonic Cleaning Method
Ultrasonic cleaning is based on the physical phenomenon of acoustic cavitation. When high-frequency sound waves typically 40 kHz are transmitted through a liquid cleaning solution, they generate millions of microscopic vacuum bubbles that form and violently implode at rates corresponding to the ultrasonic frequency. Each implosion releases an intense local jet of energy reaching temperatures of several thousand degrees Celsius and pressures exceeding 500 atmospheres but only at a microscopic scale, ensuring the parts being cleaned are unaffected by thermal or mechanical shock.
This cavitation process is the core mechanism of all ultrasonic cleaning. The energy released by each collapsing bubble penetrates into surface pores, blind holes, threads, crevices, and complex geometries that brushes, sprays, and manual wiping methods simply cannot reach. Contaminants including oils, greases, flux residues, machining chips, polishing compounds, biological debris, fingerprints, and corrosion products are dislodged from the substrate surface and dispersed into the cleaning solution, leaving a thoroughly clean part surface in a fraction of the time required by conventional methods.
The heating function complements cavitation by reducing the viscosity of oily contaminants, improving the solubility of cleaning chemistry, and accelerating the overall cleaning reaction. The degas function (where available) purges dissolved gases from the cleaning solution during the initial warm-up phase, improving cavitation intensity and ensuring optimal ultrasonic cleaning performance from the first cycle.
The degas function of the ToronUC™ DG Series is particularly valuable in production environments where cleaning solutions are freshly prepared or replaced frequently. Degassing the bath before the first cleaning cycle of the day eliminates dissolved gas interference, ensuring maximum cavitation intensity and consistent ultrasonic cleaning results from the very first load. Combined with the power-off memory function, operators can configure the DG Series once and rely on consistent, repeatable cleaning conditions every shift.
Ultrasonic Cleaning Process Steps
1. Solution Preparation — Fill the tank with an appropriate water-based cleaning solution or solvent compatible with the parts being cleaned. Add recommended cleaning chemistry at the manufacturer-specified dilution ratio.
2. Pre-Heat (if required) — Activate the heating function and set the target temperature. Allow the bath to stabilize before loading parts to ensure consistent cavitation intensity.
3. Degas (if available) — Run the degas cycle to purge dissolved gases from the cleaning solution, maximizing cavitation efficiency and cleaning effectiveness from the first production run.
4. Load & Run — Submerge parts in the basket or cleaning cradle, ensuring all surfaces are exposed to the cleaning solution. Set the timer and activate the ultrasonic transducers.
5. Rinse & Dry — Remove parts and rinse with clean water to remove residual cleaning chemistry and loosened contaminants. Dry with compressed air or a clean cloth as appropriate.
