Ultrasonic cleaning equipment

Ensuring the hygiene of equipment and machinery parts is extremely important in many industries. However, traditional cleaning methods such as manual scrubbing and high-pressure washing often take a lot of time and effort, and pose a potential risk of damage to complex details. To meet this urgent need, Vnatech – Vietnam’s leading automation solution provider – has launched ultrasonic cleaning equipment. This is a breakthrough solution, providing outstanding cleaning efficiency, helping businesses optimize processes and improve operational productivity.

What is an ultrasonic cleaning device?

Ultrasonic cleaning equipment uses advanced ultrasonic wave technology to create microscopic air bubbles capable of breaking up and completely removing dirt, grease, and rust adhering to material surfaces. , even in the smallest gaps that traditional cleaning methods cannot reach.

Structure of ultrasonic cleaning device

Ultrasonic cleaning equipment, also known as ultrasonic cleaner, is a device that uses ultrasonic waves to remove dirt, grease, and rust adhering to material surfaces. The basic structure of this device includes the following main parts:


  • The tank is made from rust-proof, chemical- and high-temperature resistant materials such as stainless steel, PVC, or titanium.
  • Tank size depends on usage needs and the size of the material to be cleaned.
  • Inside the tank there is a rack to place the material to be cleaned.

Ultrasonic generator

  • The ultrasonic generator is the most important part of the device, responsible for creating ultrasonic waves with appropriate frequency and power.
  • The ultrasonic generator is often placed on the bottom of the tank or mounted on the tank wall.
  • The most common ultrasound frequency is from 20 kHz to 50 kHz.


The amplifier is responsible for amplifying the signal from the ultrasonic generator to create wave energy strong enough to clean materials.

Control system

  • The control system includes a control panel, display screen and adjustment buttons.
  • The control system allows users to set time, temperature and ultrasonic frequency to suit their needs.

Heating system

  • The heating system is responsible for heating the solution in the tank to the desired temperature.
  • Solution temperature affects the cleaning effectiveness of ultrasonic waves.

Filter system

  • The filtration system is responsible for removing dirt, grease and other impurities from the solution in the tank.
  • The filtration system usually includes a coarse filter and a fine filter.

Solution circulation system

  • The solution circulation system is responsible for ensuring that the solution in the tank is continuously circulated.
  • The solution circulation system increases cleaning efficiency and prevents the formation of dirt in the tank.

The Working Mechanism of Ultrasonic Cleaning Devices

Ultrasonic cleaning devices utilize high-frequency sound waves (20kHz – 50kHz) to generate microscopic air bubbles within a cleaning solution. As these air bubbles collapse, they release powerful energy bursts that impact the surface of the material being cleaned, dislodging and removing contaminants, dirt, grease, and rust, even from the tiniest crevices and intricate details that traditional cleaning methods cannot reach.

Generating ultrasonic waves

  • Ultrasonic cleaning devices employ transducers that convert electrical energy into ultrasonic waves. These transducers are typically piezoelectric (utilizing the piezoelectric effect) or magnetostrictive (employing the magnetostrictive effect).
  • When a high-frequency electrical current is applied to these transducers, they vibrate, producing ultrasonic waves. These waves have high frequencies, typically ranging from 20 kHz to 40 kHz, but can reach up to hundreds of kHz in specialized applications.

Transmitting waves into the solution of ultrasonic cleaning equipment

  • The generated ultrasonic waves are transmitted from the transducers into a cleaning solution bath, often filled with water or cleaning solution mixtures.
  • As the ultrasonic waves travel through the solution, they create pressure fluctuations within the liquid, leading to alternating cycles of rapid compression and expansion.

Cavitation phenomenon of ultrasonic cleaning equipment

  • The high and low pressure oscillations in the solution induce the phenomenon of cavitation, which is the formation and rapid collapse of tiny air bubbles.
  • During the low-pressure cycle, minute air bubbles form and grow. When the high-pressure cycle occurs, these air bubbles implode, releasing powerful microjets and microshocks within the solution.

Cleaning the surface

  • When the air bubbles implode, they exert strong impact forces on the surface of the object being cleaned. This force is powerful enough to dislodge and remove contaminants, dirt, grease, oxides, and other impurities adhering to the object’s surface.
  • The microjets and microshocks generated by cavitation can penetrate into crevices, tiny holes, and hard-to-reach areas on the object, enabling thorough and effective cleaning. This is particularly crucial in applications like cleaning medical instruments, electronic components, and intricate mechanical devices.

Completing the cleaning process of ultrasonic cleaning equipment

  • After a predetermined time, depending on the level of contamination and cleaning requirements, the device completes the cleaning cycle.
  • The cleaned object can then be removed from the bath and rinsed with water or another solution to eliminate any detached contaminants. Some advanced ultrasonic cleaning systems also incorporate an automatic rinsing and drying stage to ensure the object is completely clean and dry.

Applications of ultrasonic Cleaning Devices


  • Cleaning of precision parts and components: Ultrasonic cleaning is widely employed in the manufacturing industry to meticulously clean precision parts and components used in machinery, electronics, and other equipment. The high-frequency waves effectively remove dirt, grease, metal chips, and polishing compounds, ensuring optimal performance and extending the lifespan of these components.

  • Debris removal from PCBs and electronic components: Ultrasonic cleaning is particularly effective in removing debris, solder flux residues, and contaminants from printed circuit boards (PCBs) and electronic components. The delicate nature of these components demands a cleaning method that is both powerful and gentle, which ultrasonic cleaning perfectly delivers.

Medical and dental fields
