Heated Ultrasonic Cleaner – ToronUC™ H Series
ToronUC™ H Series Heated Ultrasonic Cleaner is a professional-grade, mid-capacity industrial ultrasonic cleaner purpose-designed for workshops, automotive service operations, dental laboratories, manufacturing quality control stations, and maintenance facilities requiring powerful, reliable ultrasonic cleaning in tank sizes of 13 and 36 liters.
Available in two models — ST13A/B (13L) and ST36A/B (36L) — the H Series features dual-frequency operation at either 28 kHz or 40 kHz, giving operators the ability to select the optimal ultrasonic frequency for their cleaning task. The lower 28 kHz frequency generates larger, more energetic cavitation bubbles suited to heavy-duty industrial ultrasonic parts cleaner applications such as degreasing machined components, cleaning automotive parts, and serving as an ultrasonic carburetor cleaner for fuel system service. The higher 40 kHz frequency delivers finer, denser cavitation appropriate for precision parts, dental instruments, and ultrasonic jewelry cleaner applications where surface finish preservation is critical.
The ultrasonic power output is continuously adjustable from 0% to 100% of rated power, allowing the operator to precisely match cavitation intensity to the fragility of the parts being cleaned. A 2mm-thick SUS304 stainless steel tank provides exceptional structural rigidity and chemical resistance for long-term use with industrial cleaning chemistry. An improved PCB design with reinforced component mounting ensures stable, durable operation in demanding industrial environments.
The H Series supports both timed operation (0–30 minutes) and 24-hour continuous cleaning for overnight or long-duration decontamination runs. The integrated ceramic heating element maintains bath temperature from 20°C to 80°C for cleaning chemistry optimization across industrial degreasers, enzymatic solutions, and specialty ultrasonic cleaning concentrates.

Theory & Ultrasonic Cleaning Method
Ultrasonic cleaning operates on the principle of acoustic cavitation — the formation and violent implosion of microscopic vacuum bubbles generated by high-frequency sound waves transmitted through a liquid cleaning medium. Operating at 28 kHz or 40 kHz, the ToronUC™ ultrasonic generator drives bonded transducers that convert electrical energy into mechanical vibration, propagating pressure waves through the cleaning bath at rates of 28,000 or 40,000 cycles per second.
Each pressure wave cycle creates regions of alternating compression and rarefaction in the liquid. During rarefaction phases, dissolved gas is extracted and vacuum micro-bubbles are nucleated. These cavitation bubbles grow over successive cycles until they reach a critical size, then collapse violently — releasing localized energy in the form of shockwaves, micro-jets, and temperatures estimated at thousands of degrees Celsius (contained entirely within the microscopic bubble). The resulting implosion jets reach velocities of hundreds of meters per second and pressures exceeding 500 atmospheres, all at a scale far below the damage threshold of the parts being cleaned.
This cavitation mechanism enables ultrasonic cleaning to penetrate into surface features that no mechanical or spray cleaning method can access: threaded bores, blind holes, undercuts, mesh structures, hinged mechanisms, and complex casting geometries. Contaminants including oils, greases, lapping compounds, flux residues, scale, rust, biological debris, and carbon deposits are dislodged from the substrate and dispersed into the cleaning solution.
The choice of 28 kHz versus 40 kHz directly affects cleaning performance: 28 kHz generates larger, more energetic cavitation bubbles appropriate for heavy-duty industrial cleaning of robust metal parts, while 40 kHz produces smaller, denser bubbles with finer cleaning action better suited to precision parts with delicate surface finishes. Many ToronUC™ industrial models offer both frequencies, giving operators the flexibility to optimize cleaning for their specific application.
The H Series dual-frequency design allows the same unit to function as a gentle ultrasonic cleaner jewelry platform at 40 kHz and a high-powered industrial ultrasonic parts cleaner at 28 kHz, eliminating the need for separate machines for different cleaning applications. The 0–10 0% power adjustment further extends this versatility, enabling fine-tuned control over cavitation intensity for any substrate type from delicate precious metal jewelry through hardened steel automotive components.
Ultrasonic Cleaning Process Steps
1. Solution Preparation — Fill the tank with an appropriate aqueous cleaning chemistry (alkaline degreaser, neutral detergent, or acidic descaler) at the recommended dilution. For industrial applications, match the chemistry to the contamination type — alkaline for oils and greases, acid for scale and rust.
2. Pre-Heat to Target Temperature — Activate heating and allow the bath to reach the programmed temperature before loading parts. Elevated temperature reduces contamination viscosity, improves chemical reactivity, and enhances cavitation intensity.
3. Degas the Bath — For fresh or replacement cleaning solution, run a short degas cycle to purge dissolved gases that would otherwise suppress cavitation formation and reduce cleaning effectiveness.
4. Load Parts & Run — Suspend parts in the stainless steel cleaning basket, ensuring adequate spacing for ultrasonic energy to reach all surfaces. Set the timer and power level; initiate the cleaning cycle.
5. Inspect & Rinse — On cycle completion, remove parts and inspect cleanliness. Rinse with clean water to remove loosened contamination and cleaning chemistry residues. Dry with compressed air, clean cloth, or drying oven as appropriate.
6. Drain & Refresh Solution — Use the integrated drain valve (where fitted) to change the bath solution at the recommended interval, maintaining cleaning chemistry effectiveness and preventing re-deposition of dissolved contaminants.
