Dual Frequency Ultrasonic Cleaning Machine 28kHz 40kHz High Frequency SUS304 Stainless Steel Tank

The Dual Frequency Ultrasonic Cleaning Machine is a professional cleaning platform built for workshops that cannot compromise on surface integrity. By switching between 28 kHz and 40 kHz, and by adding an 80 kHz high frequency mode, the machine adapts the size and energy of its cavitation bubbles to the parts being cleaned. Coarse 28 kHz waves strip heavy grease, carbon and polishing compound from robust metal components, while 40 kHz provides an even balance for general maintenance, and 80 kHz delivers the gentle, high density cleaning that delicate precision parts require.

Housed in a 30 litre SUS304 stainless steel tank with a digital control panel, the unit combines ultrasonic cleaning, adjustable heating and a degassing cycle in a single bench top footprint. Operators set the frequency, temperature and timer directly on the panel, load the stainless basket and let the machine work, which removes the inconsistency of hand scrubbing and protects critical tolerances on expensive components. The result is repeatable, audit-friendly cleaning for PCB assemblies, moulds, engine parts, optical components and precision hardware.

• Dual Frequency Switching: Select 28 kHz for heavy duty degreasing or 40 kHz for everyday maintenance, matching cavitation energy to the geometry and finish of each batch.
• 80 kHz High Frequency Mode: A dedicated high frequency cycle produces dense, low energy bubbles that clean delicate surfaces such as PCB assemblies and precision optics without erosion.
• 30 Litre SUS304 Stainless Steel Tank: The seamless, corrosion resistant tank resists acidic and alkaline cleaning agents and provides generous capacity for baskets of small parts.
• Digital Control with Adjustable Heating: Temperature is adjustable from 20 to 80 degrees Celsius and the timer runs from 1 to 99 minutes, so cleaning recipes can be stored and repeated.
• Degassing Function: A degassing cycle expels dissolved air from fresh cleaning solution, so cavitation reaches full power within minutes of a tank change.
• Industrial Grade Construction: A reinforced stainless body, stainless basket and drainage valve are designed for continuous daily operation in production and maintenance environments.
• Customisation Available: Tank size, power rating, frequency combinations and voltage can be tailored for OEM and ODM projects.

The machine is equally at home in an electronics workshop and a maintenance bay. PCB and SMT lines use the high frequency mode to remove flux residue and contamination from populated boards before inspection. Tool rooms rely on the dual frequency cycle to strip polishing compounds, cutting oil and carbon from moulds, dies and machined parts. Automotive workshops clean injectors, carburettor bodies, gears and engine components, while optical and dental laboratories use the gentler setting on lenses, instruments and small precision assemblies.

Because the same tank handles both aggressive and delicate cleaning simply by changing frequency, buyers can replace two single purpose units with one machine, saving bench space and capital cost. The standard stainless basket accepts small parts in bulk, and an optional basket rack keeps larger components separated for uniform results.

Every machine is packed in a foam lined plywood case with the power cable, stainless basket, drainage hose and an English user manual included, then palletised for export. Each unit is powered up, frequency checked, temperature tested and leak inspected before it leaves the factory, and it carries a one year warranty on the ultrasonic generator and transducers. Standard lead time is 15 to 25 days after deposit, and sample units are available for evaluation.
