The frequency of the ultrasonic waves directly impacts the size of the cavitation bubbles and the intensity of their implosion:
- Lower Frequencies (e.g., 20-40 kHz):
- Produce larger cavitation bubbles.
- Result in a more aggressive cleaning action.
- Are more effective at removing larger, heavier, or stubborn contaminants like carbon deposits, heavy oils, and grease.
- Best suited for robust parts that can withstand the more intense scrubbing, such as machined metal parts, castings, and automotive components.
- Higher Frequencies (e.g., 60-130 kHz and above):
- Produce smaller cavitation bubbles.
- Result in a more gentle, yet more penetrating cleaning action.
- Are ideal for removing fine particulate matter, delicate contaminants, and for cleaning intricate geometries, small holes, or highly polished surfaces.
- Best suited for delicate items like jewelry, optical lenses, electronic components, and precision medical instruments, where a coarser clean could cause damage.
Common combinations like:
- 25 kHz / 45 kHz: A common pairing, offering a good balance between aggressive cleaning for robust items and a more general-purpose clean for a variety of parts.
- 40 kHz / 80 kHz: More focused on precision cleaning, with the 40 kHz still providing good general cleaning and the 80 kHz excelling in very fine applications.
- Increased Versatility: Cleans a broader range of items, from heavily soiled robust parts to delicate, intricate components.
- Optimized Cleaning Performance: Allows selection of the ideal frequency for specific contaminants and part sensitivities.
- Cost-Effective: Eliminates the need for multiple single-frequency machines for different cleaning needs, saving on equipment costs and space.
- Improved Efficiency: Can achieve better cleaning results in less time by using the most effective frequency for the job.
- Reduced Risk of Damage: Prevents damage to delicate items that might occur with a continuous, overly aggressive low-frequency clean.
