Ultrasonic cleaning or ultrasonic washing is a technological method that uses high-frequency sound waves (usually between 20 kHz and 400 kHz) to remove dirt, grease, rust, and other contaminants from the surfaces of various materials. This process occurs in special devices called ultrasonic baths. The energy generated in ultrasonic baths creates a large number of micro air bubbles that are present in the ultrasonic cleaning solution and then transfer into the liquid, causing rapid heating and extremely high pressure. During low-pressure periods, microscopic bubbles form, while during high pressure, these bubbles collapse or explode. These micro bubbles are capable of removing dirt, residues, and bacteria adhered to objects.

To simplify, during ultrasonic cleaning, under the influence of ultrasonic waves, the liquid compresses and expands, leading to the formation of cavitations, which results in the creation of vacuum bubbles. Each bubble strikes the object being cleaned with a pressure of about 650 to 700 bar, detaching accumulated dirt particles from the homogeneous material.

Due to its efficiency, speed, and ability to clean delicate items without damage, this method is used in many industries.

Based on all the above, we can say that ultrasonic cleaning is a clean and one of the most cost-effective methods for cleaning surfaces, equipment, and materials, providing users with comfort and impeccable results. Additionally, this cleaning technique does not cause any damage to the structure or properties of materials and is a good method for domestic, professional, or business use.

The advantages of using ultrasonic baths for ultrasonic cleaning are as follows:

1. Efficiency:
   • Ultrasonic cleaning allows for deep removal of contaminants, even from the smallest cavities and complex shapes. For example, you have an item with irregular geometry, with numerous cavities and grooves that are impossible to reach with a needle, brush, toothpick, or other cleaning tools. You can immerse this item in an ultrasonic cleaning solution in the ultrasonic bath, and the solution will penetrate all the cavities of the item and come into contact with surfaces that may not even be visible to the naked eye. Under the influence of ultrasonic waves, all surfaces in contact with the solution will be cleaned.
2. Speed:
   • The ultrasonic cleaning process is fast, usually taking only a few minutes, which increases productivity.
3. Does not require manual labor:
   • The ultrasonic cleaning process is automated in ultrasonic baths and does not require manual labor.
4. Reduction of damage risk:
   • Compared to manual cleaning or abrasive methods, ultrasonic cleaning reduces the risk of mechanical damage to the items.
5. Environmental friendliness:
   • Lower need for chemicals and water compared to conventional techniques reduces the environmental footprint.
   • Low electricity consumption.
6. Wide range of applications:
   • Can be used for various types of materials, including metal, glass, plastic, and ceramics.

The frequency of ultrasonic cleaning affects the quality and speed of ultrasonic cleaning.

All ultrasonic frequencies can generally be divided into low and high ultrasonic frequencies.

• Low frequency (20-40 kHz): Used for cleaning heavy contamination such as grease, oils, various dirt, dust, etc. These waves have stronger cavitation, which allows for more efficient and faster removal of dirt particles. This frequency is also suitable for use in laboratories for solution homogenization and has the widest range of applications.
• High frequency (40-100 kHz): Used for cleaning more delicate items whose structure is sensitive and not commonly used in everyday applications and industry, as these ultrasonic waves cannot remove heavier contamination.

Based on years of experience in manufacturing ultrasonic baths and other ultrasonic cleaning devices, as manufacturers, we have opted to produce ultrasonic baths that operate at frequencies from 37 to 40 kHz. This frequency range represents the upper limit of low frequencies.

The advantages of this frequency range of our ultrasonic baths are as follows:

• It provides sufficiently strong cavitation to remove even the most stubborn contamination;
• It offers an optimal density of ultrasonic waves per unit of surface area, thoroughly cleaning all surfaces of the items, and
• It significantly reduces the likelihood of damage to the items compared to a frequency range of 28 to 33 kHz.

Ultrasonic baths or ultrasonic tanks are very useful and efficient electrical devices designed to quickly, effectively, and cheaply clean all surfaces of objects from various contaminants, using minimal amounts of detergent and electricity, without manual labor. The range of applications for ultrasonic baths is very broad. Ultrasonic baths can be used in households, workshops, medical offices, laboratories, or industrial processes. Ultrasonic baths are named after the ultrasound generated by their generator, whose frequency is above the upper limit of human hearing (greater than 20 kHz).

In our language, the terms ultrasonic baths, ultrasonic tanks, and ultrasonic bathtubs are commonly used for these devices. There are no clear differences in the use of these terms in the literature. Some manufacturers classify these electrical devices by volume and purpose, so the term ultrasonic tanks is used for devices with smaller volume and power (commonly used in laboratories, small workshops, and service centers), while the term ultrasonic baths is used for larger and more powerful devices. Almost as a rule, the term ultrasonic bathtubs is used for ultrasonic cleaning devices in the industry.

As we already know, ultrasonic baths are complex and technologically demanding devices. Like any complex device, ultrasonic baths have multiple components and subcomponents. For easier understanding, we can say that ultrasonic baths have four main parts, which are:

• Ultrasonic generator,
• Piezoelectric transducers,
• Housing (box), and
• Tank (reservoir).

The ultrasonic generator is an essential part of every ultrasonic bath, and its operation is based on an oscillating circuit that generates an electric impulse with a specific frequency, current, and voltage. This electric signal is delivered to the piezoelectric transducer, which is glued to the ultrasonic bath tank using a special adhesive. Using the piezoelectric effect, under the influence of the electric signal, the piezoelectric transducer compresses and expands, converting electrical energy into mechanical energy, i.e., ultrasonic waves. These mechanical longitudinal waves are transmitted through the vessel to the medium (liquid). The ability of the liquid to ideally penetrate all cracks, cavities, and gaps in the object allows the ultrasonic waves to reach every smallest surface of the object.

Under the influence of ultrasonic waves, the liquid compresses and expands, leading to cavitation, which results in the formation of vacuum bubbles. Each bubble strikes the object being cleaned with a pressure of around 650 to 700 bar, detaching the accumulated dirt particles from the homogeneous material of the item being cleaned.

Depending on the model, ultrasonic baths can be equipped with one or more generators, as well as the required number of piezoelectric transducers.

The tanks of our ultrasonic baths are made of AISI 316L stainless steel, while on the market, you can find ultrasonic baths with tanks made from cheaper AISI 304, which is resistant to weaker acidic solutions.

The housings of ultrasonic baths can be made of black sheet metal or stainless steel of various grades. If made of black sheet metal, they must be protected from corrosion with an electrostatically applied plastic coating, which is later polymerized in special ovens.

Almost all models of ultrasonic baths are equipped with heaters and automatic temperature control components to switch off the heating. Depending on the volume, heaters of different powers are installed, and the heating control components can be either analog or digital.

The same applies to the timer that regulates the operating time of the ultrasonic generators. The timer can be either analog (mechanical) or digital.

The selection of an ultrasonic bath model depends on the user’s needs. The choice of the ultrasonic bath model depends on the size and mass of the item you want to clean ultrasonically. Before choosing the model, you need to measure the dimensions and weight of the largest item you want to clean ultrasonically.

For the maximum dimensions of the item, a few centimeters are always added to allow the item to be easily submerged in the ultrasonic bath tank. When choosing the depth of the tank, you should keep in mind that the item must not rest on the bottom of the ultrasonic bath tank, as this would cause damage. The item is always placed on the mesh, which is a standard part of the ultrasonic bath kit. This mesh keeps the item 1.5 to 2 cm above the bottom of the tank. Also, the tank should not be filled to the top, but 2 cm below the upper edge of the tank. For this reason, it is necessary to add 4 cm to the measured height of the item and select the ultrasonic bath model with an adequate tank depth.

Each model of the ultrasonic bath is designed so that the volume and proportions of the container, as well as the power of the ultrasonic generator, ensure optimal performance of the ultrasonic bath. Unlike many ultrasonic baths available on our market, our ultrasonic baths are intended for professional use, and their manufacturing quality ensures durability and reliability.

The power of the ultrasonic generator affects the speed and quality of cleaning. If the ultrasonic bath is equipped with a weaker generator, it will take significantly more time to clean the items, which will increase the operating resources of the ultrasonic bath. The proper relationship between volume, the power of the ultrasonic generator, and the number of piezo transducers ensures the necessary density and strength of ultrasonic waves, as well as the speed and quality of cleaning.

Many ultrasonic bath sellers, in case of a malfunction during the warranty period, replace the ultrasonic bath with another one, and after the warranty period expires, they do not provide repair options. Often, ultrasonic baths last only as long as the warranty period, and after that, users are forced to buy new ones.

The designed operating resource of our ultrasonic baths is approximately 3000 operating hours, after which they can be repaired, and their working resource is extended like a new device.

Since we are the manufacturers of every component of the ultrasonic bath (printed circuit boards, transformers, dampers, heaters, piezo transducers, housings, etc.), we guarantee service for our devices even after the warranty period.

Ultrasonic baths efficiently generate high-frequency sound waves through ultrasonic piezoelectric transducers and probes, which are submerged in a liquid and begin to vibrate. These vibrations act on the solid surface to clean it. Ultrasonic baths are used for maintaining items such as watches, jewelry, electronic parts, glass, ceramics, metals, and mechanical parts, as well as for homogenizing solutions in certain chemical reactions. Non-aggressive chemicals are not used as solutions for ultrasonic cleaning in ultrasonic baths, making them the best option for items made from sensitive materials.

Ultrasonic baths can quickly and efficiently clean objects of various shapes and sizes. There is a wide range of models, from small and portable ultrasonic baths for home use or workshops, to high-performance ultrasonic cleaning systems for industrial use. They can clean multiple items at once, depending on their size. Additionally, ultrasonic baths offer long-lasting, high-quality results. The detergent solution for ultrasonic cleaning, combined with ultrasonic waves, provides the necessary power to remove dirt, while the same power helps soften the surface being cleaned. Cleaning with these devices leaves no traces. Furthermore, tools can be automatically cleaned by programming the desired time and cleaning duration.

In recent years, people’s awareness has been changing rapidly. We can say that more and more people are becoming aware of the advantages of ultrasonic cleaning devices every day. To make their work easier, reduce cleaning costs, and provide the best quality service to the end user, more and more users have decided to purchase ultrasonic baths.

We can confidently say that ultrasonic cleaning is used in all branches of industry, as it is one of the most advanced and effective cleaning techniques in the industry today. The ability of ultrasonic cleaning to efficiently and safely remove contaminants from different materials makes it a key cleaning method in many sectors, from automotive to medical and pharmaceutical industries.

As we mentioned earlier, ultrasonic cleaning is a method that is much faster and more efficient than other traditional methods. Moreover, it has minimal environmental impact. This is a great advantage for many companies that want to reduce emissions of harmful gases and carbon dioxide, thus contributing to a better world, or striving to meet the increasingly stringent legal requirements in this field. Another advantage of ultrasonic cleaning is that it can be used on a wide range of surfaces. This means it can be used to clean everything from the smallest to the largest devices. This is useful for companies that work with different types of equipment and systems of various shapes and volumes. Additionally, ultrasonic cleaning is a cost-effective option for businesses. The energy used for the process is relatively low, which allows companies to reduce their costs without compromising the quality of results. On the other hand, ultrasonic cleaning saves time, as it usually takes less time than other methods.

In practice, the application of ultrasonic cleaning in an industrial sector is not solely dependent on the needs of technological processes, but rather on the decision of the company’s management. If the company manager is familiar with the possibilities and advantages of ultrasonic cleaning, it is highly likely that the decision to implement ultrasonic cleaning will be made and executed.

After recognizing the benefits of ultrasonic cleaning, company managers see the advantages of this method and decide to implement it, as they become aware of its efficiency, savings, and ultimately profit.

Preventive maintenance of tools and systems in all industrial sectors plays a crucial role in preserving their resources, significantly reducing corrective maintenance costs, and reducing the depreciation of fixed assets. Clean and functional tools and equipment contribute to higher-quality products and services, while also reducing the possibility of scrap in production, which has a significant impact on the company’s profits.

It is well known that tools and equipment must be kept in the best possible condition to optimize their performance. This is the reason why cleaning and maintaining tools has become of great importance for manufacturers as well as for end users.

To ensure this, timely and adequate cleaning is necessary, and this is where ultrasonic cleaning comes into play. Ultrasonic devices are indispensable equipment in the world of manufacturing and tool maintenance.

Ultrasonic cleaning offers numerous advantages, such as: not damaging metal components, efficiently cleaning narrow and hard-to-reach spaces, and providing a good level of hygiene and sterilization.

There are different detergents for ultrasonic cleaning, each with specific characteristics that allow it to achieve a particular goal. The choice of solution for ultrasonic cleaning depends on the material and type of dirt you want to remove. For example, the liquids used for cleaning metal will not be the same as those used for cleaning glass. Suitable liquids for ultrasonic cleaning may contain various types of salts, such as sodium chloride, sodium carbonate, phosphate, nitrate, and various acids. These salts should have high solubility in water so the liquid can easily remove dirt from the surface. Detergents are often added to the liquid to enable deeper cleaning. Liquids used for ultrasonic cleaning must be free of contaminants to avoid damage to the item. Therefore, it is very important to periodically change the liquid or filter it to ensure that it is free of unwanted particles.

Since we didn’t want to leave this very important aspect of ultrasonic cleaning to chance, we are manufacturers of various types of ultrasonic cleaning detergents. Each of our detergents is specially and carefully developed to ensure maximum ultrasonic cleaning results. In our product range, we offer several dozen types of ultrasonic cleaning detergents, each with its specific purpose.

If you are unsure about which ultrasonic cleaning detergent you need, please contact our team, who will provide you with expert help and support.

Heating the solution in ultrasonic tank reservoirs affects the quality of ultrasonic cleaning.

In many ultrasonic cleaning systems, the reservoir is equipped with heaters that help increase the temperature of the solution, which improves cleaning efficiency. The heating itself serves a dual purpose. The first purpose of the heater is to warm up the detergent solution, which works more efficiently at higher temperatures, and the second is to accelerate the degassing process of the solution.

When filling the ultrasonic tank reservoir with detergent solution, the solution contains gas molecules (air) that can significantly dampen and interfere with the propagation of ultrasonic waves. The process of expelling trapped air molecules from the solution is called degassing. Degassing is a process that will occur even without increased solution temperature in ultrasonic tanks, but it will take significantly longer time.

When heating the solution during ultrasonic cleaning, it should be noted that temperatures above 60ºC can reduce the effectiveness of the ultrasonic waves. Empirical results have shown that the ideal temperature for ultrasonic cleaning in ultrasonic tanks is between 40 and 55ºC.

1. Preparation of items:
   • The larger pieces of dirt or debris are first removed. This can include manual cleaning, blowing with compressed air, wiping, or using mechanical tools.
2. Submerging the item for ultrasonic cleaning:
   • The items are carefully submerged into the reservoir with the prepared solution. It is important that all parts of the item are fully submerged to ensure even exposure to ultrasonic waves.
3. Activating the ultrasonic waves:
   • Once the ultrasonic generator is turned on, waves begin to transmit through the liquid. The cleaning time can vary from a few minutes to half an hour, depending on the complexity of the contamination and the type of material.
4. Rinsing and drying:
   • After the process is completed, the items are typically rinsed in clean water to remove any remaining solution and contaminants. They are then dried either by air or using a dryer.

Like any technological method, ultrasonic cleaning has certain limitations:

1. Material Incompatibility:
   • Some materials, such as soft plastics or colored metals, may be sensitive to ultrasound and could be damaged.
2. Choice of Solution:
   • Inappropriate detergents may reduce efficiency or even damage items. It is important to use detergents specifically formulated for the type of contamination and material being cleaned.
3. Adjustment:
   • Each application requires adjustment of the ultrasonic cleaning time and temperature, which may require additional testing and optimization.
4. Equipment Costs:
   • In the short term, the investment in ultrasonic equipment may be high, especially for industrial systems, but it quickly pays off through savings and optimization of technological processes.

Ultrasonic cleaning technology is constantly evolving. Future trends are expected to include:

• Intelligent systems: Integration with smart sensors and IoT technology for automatic adjustment of cleaning parameters based on contamination analysis.
• Eco-friendly solutions: Development of biodegradable and environmentally friendly detergents that will further reduce the negative impact on the environment.
• Combination of technologies: Merging ultrasound with other cleaning methods, such as laser or plasma, to achieve even better results.
