Compact Ultrasonic Cleaner – ToronUC™ S Series
ToronUC™ S Series Compact Ultrasonic Cleaner is a compact, digitally controlled benchtop ultrasonic cleaning system constructed entirely from 304 stainless steel, engineered to deliver professional-grade ultrasonic cleaning performance across a broad range of benchtop, counter-top, and light industrial applications. Starting from an ultra-compact 1.3-liter model and scaling up to 27 liters, the S Series covers the widest capacity range in the ToronUC™ family.
Each unit features a full LED digital display for precise real-time monitoring of cleaning time and temperature, ceramic heating elements for improved thermal efficiency and longevity, and high-performance ultrasonic transducers for powerful and reliable cavitation throughout the cleaning cycle. The all-stainless construction — from the external case panels to the inner cleaning tank — provides superior corrosion resistance for use with a wide range of aqueous cleaning solutions.
Drainage taps and cooling fans are integrated on 6L and larger models, supporting continuous-production industrial ultrasonic cleaning workflows. Ergonomic handles on larger models and skid-proof rubber feet across all models enhance safe and practical laboratory and workshop operation. The ToronUC™ S Series is well-suited as a versatile ultrasonic jewelry cleaner, ultrasonic glasses cleaner, dental ultrasonic cleaner, and general-purpose industrial ultrasonic cleaner for North American laboratories, workshops, and service facilities.

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.
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.
