Explore industrial ultrasonic cleaners for compatible workshop parts, tools and mechanical components. Compare our 30L and 38L machines around the size of your workpieces, the contamination you need to remove and the controls your cleaning process requires.
Look beyond the litre rating: usable basket space, material compatibility and the cleaning liquid all affect suitability. For equipment supporting other cleaning tasks, browse our Cleaning Equipment collection.
An ultrasonic cleaner treats immersed components using sound energy transmitted through a cleaning liquid. The process creates cavitation: small bubbles form and collapse, helping dislodge contamination from surfaces in contact with the liquid. This can assist cleaning around recesses and detailed shapes that are difficult to reach manually.
Choose the machine around the complete process. The part must fit, its materials must tolerate the treatment, and the liquid and operating settings must suit the contamination. A larger bath or higher setting does not automatically produce a better result.
| Model | Listed features | Selection checks |
|---|---|---|
| CJ-100SD 30L ultrasonic cleaner | 30L tank; listed 40kHz operation; integrated heating; digital controls; degas function and drainage. | Confirm usable basket dimensions, the supplied configuration and the settings needed for your components. |
| 38L industrial ultrasonic cleaner | 38L tank; listed 40kHz operation; 20–80°C heating range; adjustable timing and drainage. | Confirm component fit, basket clearance and any additional process features required for repeated batches. |
The nominal capacities differ by 8 litres, but this does not establish an equivalent increase in component size or batch throughput. Compare the usable cleaning space and supplied features before deciding.
Record length, width and height, including protruding fittings. Check the usable basket dimensions and working immersion depth rather than relying on the external machine size or nominal tank volume. Basket space is smaller than the surrounding tank.
For batches, plan how parts will sit without overcrowding or trapping air. Internal cavities need a loading arrangement that lets the liquid reach the surfaces requiring treatment. Ask about basket load limits if you intend to clean heavy components.
Use the support arrangement prescribed for the machine. Avoid placing components directly on the tank floor; a suitable basket keeps parts supported above it. Confirm whether the required basket is included before ordering.
Both product listings identify 40kHz operation. Frequency describes the ultrasonic oscillation rate, while power and heating describe separate characteristics. Compare these specifications individually rather than treating them as interchangeable measures of cleaning performance.
When comparing wattages, establish whether each figure represents ultrasonic power, heater power or total input. Power per litre alone cannot account for loading, bath geometry, operating modes or the cleaning chemistry.
Heating can support a compatible cleaning process, but the appropriate temperature depends on the liquid, contamination and component. A machine's maximum temperature is an operating limit, not a recommended setting for every job.
For removable automotive parts, establish which materials and finishes are present and whether disassembly is required. Seals, coatings, adhesives and sensitive assemblies can change suitability. A cleaner large enough to hold an item is not automatically suitable for treating it.
Provide component dimensions and contamination details when comparing the 30L parts cleaner with the 38L ultrasonic cleaner.
Do not choose a liquid solely because it is sold for metal cleaning. Confirm compatibility with the specific alloy, finish and contamination through the chemical supplier's guidance. Include the concentration, temperature and contact time in that check.
For tools, bearings and assembled components, also establish whether cleaning could remove necessary lubrication and what inspection, drying or re-lubrication steps are required afterwards.
Freshly prepared liquid contains gas that can affect ultrasonic action. Degassing helps prepare the bath by removing gas before cleaning. Use the procedure specified for the actual machine; do not assume every cleaner has the same mode or preparation time.
There is no universal cycle time. Follow the applicable equipment and chemical guidance, then assess the result using a suitable inspection method. Increasing time repeatedly is not a substitute for checking chemistry, loading and material suitability.
Plan liquid replacement around contamination and the cleaning result, rather than assuming every bath lasts a fixed number of days. Monitor the process and follow the solution supplier's guidance. Replace contaminated liquid when required and prepare the fresh bath correctly.
The listed cleaners include drainage, which helps emptying. Allow space for controlled draining and follow the instructions for cooling, shutdown and cleaning the tank. Handle and dispose of used liquid according to its composition and collected contamination.
Include rinsing and drying in your workflow where the process requires them. Cleaning residues left on a component can affect the finished result, and some parts need further care before storage or reassembly.

No. Use only liquids approved for the machine and process. Do not put flammable liquids directly into an ordinary ultrasonic cleaning tank. Follow the equipment instructions and chemical supplier's guidance.
Ultrasonic cleaning does not, by itself, establish sterilisation. Where a validated disinfection or sterilisation process is required, select equipment and procedures specifically approved for that purpose.
Choose the machine that accommodates your components and workload with suitable controls. Extra volume can mean more liquid to prepare, heat and replace. Confirm that the additional space provides a practical benefit.
Exclude items that are incompatible with immersion, ultrasonic action, the chosen chemistry or temperature. Check component documentation rather than relying on a general list, particularly for coated, delicate or assembled items.
