Dual Frequency Ultrasonic Cleaning Machine 28kHz 40kHz Switchable SUS304 Stainless Steel Tank 22L

The Dual Frequency Ultrasonic Cleaning Machine gives workshops one tank that behaves like two. A single switch moves the generator between 28 kHz and 40 kHz, so the same bench top unit can attack heavy grease and carbon one moment and gently clean delicate assemblies the next. This flexibility removes the need to buy and store separate machines for coarse and fine work, and it keeps cleaning recipes consistent across every operator on the floor.

Built around a 22 litre SUS304 stainless steel tank, a 480 W ultrasonic generator, a 400 W heating element and a digital control panel, the machine covers the full working range of a busy maintenance bench. Operators set the frequency, temperature and timer on the front panel, add the stainless basket, and let cavitation do the work, achieving a level of cleanliness that hand brushing simply cannot match while protecting the tolerances of expensive components.

• Dual Frequency Switching: Choose 28 kHz for powerful degreasing of robust metal parts or 40 kHz for a finer, more uniform clean on general components.
• High Density Cavitation: Both frequencies generate dense micro bubbles that reach blind holes, threads and internal channels that brushing and spraying leave behind.
• 22 Litre SUS304 Stainless Steel Tank: The seamless corrosion resistant tank stands up to alkaline and mild acidic cleaners and takes a full basket of small parts.
• Digital Control with Heating: Temperature is adjustable from 20 to 80 degrees Celsius and the timer runs from 1 to 99 minutes, making cleaning cycles easy to standardise.
• Degassing Function: A dedicated degassing cycle removes dissolved air from fresh solution so cavitation performs at full strength right after a tank change.
• Robust Bench Top Build: A reinforced stainless body, stainless basket and drain valve are engineered for continuous daily use in production and repair environments.
• OEM and ODM Support: Tank capacity, power rating, frequency pairing and voltage can be adapted for private label programmes.

The machine suits any environment where parts alternate between dirty and delicate. Tool rooms use the 28 kHz cycle to strip polishing compound, cutting oil and carbon from moulds, dies and machined parts, then switch to 40 kHz for finer assemblies. Electronics and SMT workshops clean flux residue from boards and stencils, while jewellery, optical and dental benches rely on the gentler frequency for frames, lenses and instruments.

Automotive service centres clean injectors, carburettor bodies, bearings and brake components in bulk, and laboratories use the unit for glassware and precision hardware. Because one tank covers both aggressive and gentle cleaning, buyers reduce equipment count, bench space and capital cost without sacrificing results.

Each machine ships in a foam lined plywood case with the power cable, stainless basket, drain hose and an English manual, then is palletised for export. Every unit is powered up, frequency tested, temperature verified and leak checked before dispatch, 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.
