Ultrasonic cleaning is a powerful and efficient method for removing contaminants from a wide range of materials and components. Whether you're in manufacturing, engineering, healthcare, or jewellery restoration, or planning to use an ultrasonic cleaner at home, selecting the right ultrasonic cleaner is essential to achieving optimal results.
Key Considerations When Choosing an Ultrasonic Cleaner
1. Size Matters
Start by assessing the size of the items you plan to clean. Whether you're cleaning a single item or a batch, it's crucial to ensure there is sufficient space around each object for cavitation to occur. Cavitation, the formation and collapse of microscopic bubbles, is the core mechanism of ultrasonic cleaning, and it requires space to work effectively.
Begin by reviewing the basket dimensions, as these will determine the appropriate tank size for your application (we advise the use of a basket in the ultrasonic tank to protect items and the bottom of the tank from wear and tear).
2. Power Supply Requirements
Ultrasonic cleaners come in various capacities, and power supply needs vary accordingly. For large freestanding units with a heating power of 4kW or more, a three-phase power supply is required. Models with capacities between 57–112 litres may offer a choice between single-phase and three-phase systems, giving you flexibility depending on your facility’s setup.
All our ultrasonic cleaners up to and including the 36 litre-capacity models have a standard 220V plug.
3. Frequency Selection
Ultrasonic frequency plays a vital role in cleaning performance. We offer the following frequency options as standard :
- 28kHz: Produces larger cavitation bubbles, delivering a coarser and more powerful cleaning action - ideal for robust components.
- 40kHz: Generates smaller bubbles for a gentler and more refined clean, suitable for delicate items.
Choosing the right frequency ensures you get the best results without compromising the integrity of the items being cleaned. Our benchtop ultrasonic cleaners from 0.7-27L operate on a 40kHz frequency, while our larger cleaners offer either 28 or 40kHz in each size. Should you need a different frequency for your application, we can create a custom ultrasonic cleaner for you.
4. Features That Enhance Performance
Modern ultrasonic cleaners offer a range of features to suit different applications:
- Choice of operation for benchtop models, including dial, digital, and Cavitek interfaces to suit different user preferences and precision requirements
- Degas program to condition the solution prior to cleaning
Larger, freestanding models:
- Adjustable power settings
- Rising platforms for heavy items
- Filtration systems to maintain fluid cleanliness
- Oil skimmers to remove surface contaminants
- Touchscreen controls for ease of use
