How to choose the right frequency for digital ultrasonic cleaners?


The cleaning effect of the industrial ultrasonic cleaning system depends on the high-energy collapse of the tiny air blow bubbles formed by the sound waves in the cleaning solution. When the bubbles are ruptured, they release the energy that burst in an instant and remove impurities and pollutants from the surface to be cleaned. The higher the frequency, the shorter the air bubbles grow between the sound wave cycle, and the smaller the bubble. The energy of small bubbles is low, but for the given power input, they will be more. Therefore, high-frequency ultrasonic cleaning with a large number of tiny bubbles can provide gentle cleaning of fine distribution, and a lower frequency with fewer and larger bubbles can provide more dynamic coarse cleaning effects. Choosing a device that can provide the correct ultrasonic cleaning frequency for your application is the key to getting effective cleaning.

Cleaning metal and glass parts require a lower frequency

The low-frequency range of blue whale industrial ultrasonic cleaning systems ranges from 26 kHz to 38 kHz. They remove hard surface contaminants, but their high clean energy is not suitable for soft materials or precision parts. Typical items that can be cleaned using these systems are hard metal working parts, glass, jewelry, wires, and medical equipment.

Use intermediate frequencies for precision cleaning

The blue whale ultrasonic cleaner works successfully in the 78 kHz to 160 kHz medium frequency range to clean less rigid parts and materials. Cleaning of hard disk drives, LCDs, solar cells and panels, aluminum components, quartz transducers, and ceramic components are typical applications. It also provides a water resonance system (WRS) that adjusts clean water to optimize bubble formation and improve cleaning performance.

Use High frequency for gentle cleaning

In the range of 450 kHz to 950 kHz, high-frequency cleaning will be more accurate and will not damage precision components. The blue whale industrial ultrasonic cleaner cleans parts made of soft materials with complex surfaces that require careful handling. Typical components cleaned at these frequencies include semiconductor wafers, electronic components, precision medical devices, and LEDs. A specially designed ultrasonic generator is used in conjunction with a nozzle for directional cleaning of hard drive surfaces, Flat panel display glass, and semiconductor wafers.

Flexible cleaning options

For industries with a variety of cleaning applications, we should of course choose industrial ultrasonic cleaners that operate at the appropriate frequency to perform the cleaning task. But instead of requiring customers to buy products at multiple frequencies, we can provide a cleaning system that operates at the desired frequency.

With its extensive flexibility, blue whale's homemade ultrasonic cleaners can handle a variety of cleaning applications in a single unit, regardless of cleaning requirements, we can all recommend the right frequency for you to get the most efficient cleaning solution.
