Why Ultrasonic Cleaners Provide the Best Green Option for Industrial Cleaning

Ultrasonic cleaning systems offer superior cleaning performance as well as a cleaner environmental footprint. Traditional cleaning involves the use of toxic cleaning chemicals and mechanical scrubbing. The chemicals have to be aggressive to clean the part surfaces completely in a reasonable time. However, some industrial cleaning applications take longer periods to complete. They involve other procedures such as prolonged soaking and the final step of mechanical scrubbing to remove leftover traces of contaminants. Mechanical parts are also labor-intensive and can damage the parts to be cleaned. 



Despite these procedures, some contaminants may remain on the part surfaces, and even more so in harder-to-reach places such as holes and crevices, along cracks and inside tanks and reservoirs. It results in poorly cleaned parts that may contaminate processing. Ultrasonic cleaning systems, on the other hand, do not require chemicals or mechanical brushing. They require only plain water, or plain water and mild detergent to clean the parts quickly and thoroughly.



In an ultrasonic cleaning system, the ultrasonic transducer creates high-frequency sound waves in the cleaning solution and the sound waves, in turn, produce microscopic cavitation bubbles in the low-pressure troughs. The bubbles collapse in the high-pressure peaks of the sound waves, releasing a jet of cleaning solution that strikes the part surface, removing the dirt particles. The cavitation bubbles even pass-through holes, crevices, and complex shapes, cleaning them thoroughly.



Ultrasonic cleaning systems don't require purchasing, storing, handling, and neutralizing chemicals. Thus, the work environment is safer for workers and free of aggressive chemicals that require protective measures.

As environmental legislation and worker safety regulations have become stringent, ultrasonic cleaners are the wave of the future. They are environmentally friendly and do not require the use of caustic chemicals. Other benefits of ultrasonic cleaners include low operating costs, low capital costs, lower compliance costs, improved productivity and output, and safer work environment.

Is De-Ionized Water Needed for Ultrasonic Cleaning?

The use of de-ionized water can improve the performance of ultrasonic cleaning systems and for rinsing components that have been cleaned. The use of ordinary water is adequate for cleaning lightly contaminated parts or for parts that can withstand robust cleaning. A mild detergent or the application of heat may be needed when cleaning heavily contaminated parts or fragile parts. For parts that cannot withstand mild detergent or heat, the use de-ionized water is the best way to speed up the cleaning process and to ensure even and thorough cleaning.



Ordinary water naturally comes with traces of impurities. To turn ordinary water into de-ionized water, it is first filtered to remove organic matter. Then it is passed through an ion exchange bed. The ion exchange resins attract an remove the dissolved ions which produces very pure water.



De-ionized water helps the performance of ultrasonic cleaning systems in a number of ways. As it doesn't contain contaminants, ultrasonic cleaning applications using de-ionized water and detergents are more effective. The detergents maintain their cleaning power due to the absence of impurities of de-ionized water. Once the detergents are used, the cleaning solution has to be rinsed off after cleaning is done.



If the rinsing is done with de-ionized water, it doesn't leave any residue when dry. Ordinary water, on the other hand, leaves traces of impurities such as salts or organic films on cleaned parts.



Parts such as machined components or metal parts can have metallic dust on the surfaces. The microscopic cavitation bubbles produced by the ultrasonic cleaning systems can dislodge the dust particles and de-ionized water quickly absorbs all the metallic ions which dissolve in the cleaning solution. This type of cleaning application benefits from the use of de-ionized water but the detergents and heating are not needed.

Using Industrial Ultrasonic Cleaners to Clean Disk Drives

Disk drives and components that include aluminium disk platter blanks and metal read/write heads are usually manufactured in standard industrial facilities. The processes used in their fabrication includes machining, stamping, punching, polishing, and molding using industrial chemicals for cooling, lubrication and as abrasives.

Before they are sent to special facilities for assembly, the hard drive components arriving from the industrial manufacturer must be cleaned thoroughly. Traces of industrial chemicals, contaminants added during shipment and particles adhering to platter surfaces must be removed completely. The components of hard disk drives must be especially clean, since the heads float very close over the platter surface and excessive contamination will not allow them to gather and store data.

High performance industrial ultrasonic cleaners can perform these types of cleaning tasks quickly and effectively. An industrial ultrasonic cleaning system produces microscopic cavitation bubbles in the solution of a cleaning tank. The bubbles form and collapse in time with the ultrasonic frequency. When a bubble collapses by the surface of a hard disk component, it produces a scrubbing action that removes dirt and contaminants. The bubbles form wherever the cleaning solution can penetrate, even around crevices, tinier holes and irregular shapes of disk read/write head.

To achieve optimum cleanliness, hard disk drive manufacturers usually use several frequencies to clean various components to remove specific contaminants. Deionized water is the preferred cleaning solution since cleaning agents leave traces that then have to be removed as well. For components that have surface lubricants, a mild detergent and/or heating the cleaning solution may make complete removal easier.

Kaijo offers free consulting to help customers choose the right industrial ultrasonic cleaners that will meet their requirements.

How an Ultrasonic Cleaner is Configured for Different Cleaning Application

From delicate parts to large machined components, the job of an industrial ultrasonic parts cleaner can be challenging and complicated largely due to different cleaning needs. The best manufacturers offer both standard and customized solutions, with components which can be mixed and matched to any specific needs.

The essential components that are selected for configuring ultrasonic parts cleaners consist of:

1) Generator – creates and amplifies an ultrasonic signal;
2) Transducer – creates physical ultrasonic sound waves from the signal created;
3) Cleaning bath – holds the parts or items that need to be cleaned.

Each of these parts is selected at the configuration stage. Custom features can also be added to these standard components as well in order to meet specific customer’s needs.

When configuring an ultrasonic cleaner, the first step is to look at the cleaning requirements which are usually described by the customer. Then, the design personnel determines the specific equipment needed to meet those requirements, depending on the various factors that include the nature of the contamination and the material of the part being cleaned. Other variables including the size of the parts being cleaned are also considered. For instance, for a single-use application, a low-frequency generator may be used; in the case of larger cleaning baths, multiple transducers can be installed to achieve optimum cleaning performance.

Once the design characteristics are determined, the designers start to look at the kind of transducers to use – there are immersible, mounted and bolt-on varieties – which can be used for different cleaning needs. For example, if the bath to use is an existing tank at the customer's own facility, an immersible transducer is ideal to use. There are also other customizable options which include mounts, a heater and the use of the resonance system, among others.

How Ultrasonic Cleaners Provide Effective Cleaning Before Plating or Coating

Ultrasonic parts cleaners are the ideal choice for cleaning metal or plastic parts that will be plated or coated. Parts often have contaminants as a result of machining, buffing compound, or shop dirt. Surface parts that are contaminated will encounter problems with adhesion when they're being coated or plated. Ultrasonic cleaners provide a fast and thorough cleaning of part surfaces, saving time and ensuring complete adhesion. The use of ultrasonic cleaners is completely safe and does not require the use of chemicals to remove dirt or contaminants. The benefits include quicker processing, better throughput, and higher quality results.

How does an ultrasonic parts cleaner work in cleaning parts to be plated or coated? It involves the production of microscopic cavitation bubbles in the cleaning tank. An ultrasonic generator produces a high-frequency electric signal to a transducer, which converts the signal into sound waves as they encounter the cleaning solution.

These sound waves in the cleaning liquid have high-pressure peaks and low-pressure troughs. Cavitation bubbles are formed at low pressure and collapse at high-pressure peaks. The continuous cavitation action results in a mechanical cleaning action and scrubbing effect on the surfaces of the parts to be cleaned. Contaminants and particles are dislodged and carried away by the cleaning solution.


Choosing the appropriate frequency, power and cleaning system configuration is important for effective cleaning before plating or coating. The frequency depends on the structure of the parts as well as the nature of the surface contamination that needs to be removed. Kaijo’s experts work with customers to ensure the right frequency, power and system configuration is used to provide optimum results for their specific cleaning application. 

Kaijo’s ultrasonic parts cleaners provide fast and thorough cleaning of parts, ensuring total and effective adhesion of coatings and planting applications.

How to Buy the Right Ultrasonic Cleaner for Your Application – Part 2

The most important things to consider in choosing an ultrasonic cleaning system are the size of the tank, the frequency of the system and the power it can provide. Aside from these the accessories such as a tank temperature heater and holding basket should also be considered when choosing the right system for a cleaning application.

Cleaning tank heater:

Ultrasonic cleaners work by generating tiny cavitation bubbles which clean and scrub surfaces of parts to remove contamination. However, when contaminants on surfaces are hard deposits that are difficult to clean, the cleaning action of the bubbles will take more time. In these cases using a heating, the liquid in the cleaning tank will help to soften or loosen the hardened contamination from the surfaces being cleaned. That's where the cleaning tank heater enters the picture.

While cleaning tank heaters are a useful option for ultrasonic cleaning systems, they should be designed for the application. Untreated plain water (below 100 degrees centigrade) may be used most of the time but mild cleaning solutions can also be used. If the cleaning solution is considered, the heat settings should be controlled so that solution won't start boiling. The ultrasonic transducer should also be designed in a way that it will be able to withstand high temperatures.

Using sweep frequencies:
Kaijo’s ultrasonic cleaning systems operate at certain frequencies and are designed to achieve the optimum cleaning results according to the size of the cavitation bubbles and their cleaning intensity. However, a system may experience some unpredictable negative effects. This results in the ultrasonic waves canceling each other and no cleaning occurs. Using sweep frequencies will reduce this effect.

Water resonance system

The water resonance system helps ensure even cleaning action throughout the tank. The water treatment of a water resonance system provides an even distribution of nuclei essential for bubble formation. This allows bubbles to form everywhere within the cleaning solution rather than mostly above the ultrasonic transducer. This provides an even cleaning action on everything placed in the cleaning tank.

How to Buy the Right Ultrasonic Cleaner for Your Application – Part I

Industrial ultrasonic cleaners can effectively clean parts rapidly and completely if they are correctly configured for the specific cleaning application.

An ultrasonic cleaning system typically consists of a signal generator, a transducer, and a cleaning tank. Each component of an ultrasonic cleaning system should be carefully selected, and they must work together so that the entire system can clean parts and tools effectively.

Cleaning application – Ultrasonic cleaners usually remove light contamination like dust, films, and residues quickly and effectively. For cleaning parts that have heavy contamination (such as grease), the application of heat or mild solvents may be added.

Size and power – Effective cleaning also depends on the size of the parts to be cleaned, as well as the power selection. For bigger parts or parts that have unusual shapes, a custom-made tank may be appropriate. Naturally, bigger tanks will require more power than tanks of a standard size. However, too much power can cause pitting on the surfaces of the parts being cleaned, that's why selecting the right amount of power is as important as selecting the right tank size. The bottom line is that the ultrasonic waves need to be evenly distributed in the cleaning tank so that it can clean parts thoroughly and effectively.

Since industrial ultrasonic cleaning is carried out by the high-frequency sound waves in the cleaning solution, the cleaning tank (and the parts inside it) may vibrate slightly as cleaning takes place. This means that the parts should be suspended in the cleaning solution to avoid contact with the walls and the bottom of the cleaning tank, as even slight vibrations can cause damage.

Do you have questions? For more details read the complete article, “How to Buy the Right Ultrasonic Cleaner for Your Application – Part I”. You may also call Kaijo at 408-675-5575 or email info@kaijo-shibuya.com if you have questions or would like to discuss your industrial cleaning needs.

Selecting an Ultrasonic Transducer for Your Cleaning Application

An ultrasonic cleaning system consists of a generator, an ultrasonic transducer, and a cleaning tank.

The role of the ultrasonic cleaning transducer is to transform an electrical high-frequency signal from the generator into ultrasonic sound waves in the cleaning solution contained in the tank.

Kaijo's ultrasonic cleaning transducers are made up of an electrical section that receives the electrical high-frequency signal from the generator and a mechanical section that vibrates at a high frequency. Once received, the electric signal is applied across piezoelectric crystals which change the signal into vibrations.

When the transducer is immersed in the liquid or cleaning solution, these vibrations result in corresponding ultrasonic waves in the solution. These ultrasonic waves travel through the liquid as compression peaks and troughs. Cavitation bubbles form in the troughs because of the low pressure, and they collapse again in high-pressure peaks. As bubbles collapse, they release an extremely powerful jet of cleaning solution that dislodges dirt, grime, and other forms of contaminants from the surface of the parts that are being cleaned in the solution.

These bubbles create a fast and effective cleaning action without damaging the underlying surface; they can clean even in the most inaccessible areas of the parts being cleaned. The result is rapid, efficient and thorough cleaning.

Types of ultrasonic cleaning transducers:

• Immersible transducer – A more flexible type of transducer, it can be placed in any tank in the cleaning solution. It can be positioned horizontally or vertically, as long as it is completely submerged in the liquid.
• Bolt-on or mounted transducer – It is permanently installed onto the walls or bottom of the cleaning tank.

For more details read the complete article titled “Selecting an Ultrasonic Transducer for Your Cleaning Application”. If you have questions about Kaijo’s ultrasonic transducers or would like to discuss the specific cleaning requirements for your application call 408-675-5575 or email info@kaijo-shibuya.com.

How Ultrasonic Generators Work to Provide Optimum Cleaning Results

The role of an ultrasonic generator is essential since it generates the high-frequency electric signal that is required for an ultrasonic cleaning system to operate efficiently. These devices will produce frequencies that range between 20 kHz up to 1 MHz. Ultrasonic generators also ensure that the selected power and frequency are properly controlled and maintained.

Ultrasonic cleaning systems work by creating high-frequency sound waves within a cleaning solution to remove surface contaminants and dirt from various parts and devices. The parts and components being cleaned are immersed within a cleaning tank. When the right frequency is selected, the ultrasonic cleaning system will clean the parts and components quickly and effectively – even for items that have holes, irregular shapes, curves and crevices.

The cleaning performance of the ultrasonic cleaning system depends on the action of the cavitation bubbles created by the high-frequency sound waves within the cleaning solution. These bubbles are formed in the wave pressure troughs and disappear in the pressure peaks – this action creates a powerful and intense scrubbing and cleaning action, dislodging contaminants from the surface of the immersed parts.

An Ultrasonic generator needs to fit the production environment and also match cleaning application requirements. Once the specific cleaning application requirements are defined, selecting the right ultrasonic generator which produces the appropriate frequency, as well as the corresponding transducers and cleaning tank is clear. If an ultrasonic cleaner is used the same way, to clean one kind of part made of the same material with the same contaminants, a single-frequency generator is usually the most cost effective option. The power of the ultrasonic generator must also be high enough to fill the cleaning tank with ultrasonic waves and the design must ensure that the wave pattern is uniform for effective cleaning.

How Ultrasonic Cleaning Systems Are Used to Clean Industrial Lenses

Ultrasonic cleaning systems can effectively clean glass lenses, however due to the special characteristics of lenses, selecting the correct ultrasonic frequency, power and bath is critical.

Industrial lenses that are made of pure glass are ideal candidates for ultrasonic cleaning. The ultrasonic generator produces high-frequency electronic signal, and the transducer immersed in the ultrasonic bath converts that signal to ultrasonic waves within the liquid.  The waves within the cleaning bath generate cavitation bubbles in the pressure troughs, and then they collapse in the pressure peaks. The action of the cavitation bubbles produces a powerful scrubbing and cleaning action against the hard surfaces of the lenses, dislodging contaminants from the surface.

While glass itself would not be affected by ultrasonic cleaning systems, it may have been treated with a special coating or surface treatments that can be damaged at certain frequencies, in heated baths or when used with added detergents.

Lower frequencies – Produce larger cavitation bubbles with a more robust cleaning action.

High frequencies – Produce smaller cavitation bubbles with a gentler cleaning action.

The power produced by the ultrasonic system affects the cleaning time. If the power is too low, too few bubbles are generated, and the cleaning process will take longer. The power level should be exactly enough so that it can produce the maximum amount of cavitation bubbles that will allow the quickest and most thorough cleaning action on industrial lenses.

Robust cleaning with the addition of detergents and/or heat will speed up the cleaning process on pure glass lens. However, if the lens has any coating, the same cleaning measures may damage the lens coating. Thus, the required frequency for cleaning coated glass lenses must be high enough to avoid damaging coatings that are softer than pure glass.

What Is the Definition of Ultrasonic and Megasonic Frequency?

Sound exists at much higher frequencies, which includes both ultrasonic and megasonic ranges. While these may not be audible to human hearing, these frequencies can be used in practical applications in megasonic and ultrasonic cleaning systems.

So how do megasonic and ultrasonic cleaning systems work? When liquids and gases are subjected to high-frequency sound at powerful energy levels, it leads to the formation of microscopic tears in these mediums.

When megasonic or ultrasonic sound energy goes through these mediums, it causes the microscopic tears to form into bubbles every second, and these bubbles collapse quickly. This process is known as “cavitation.”

Cavitation bubbles are high-energy bubbles. As each of these bubbles forms and collapses quickly, it generates shockwaves. When you place an object into these cavitation bubbles, it tends to be subjected to the energy of these implosions. These cavitation bubbles are so powerful that they can dislodge dirt or other contaminants off the surface of the object exposed. This is the kind of phenomenon which both the megasonic and ultrasonic cleaning system approach utilizes.

The megasonic and ultrasonic cleaning approach is revolutionary. This cleaning approach is faster, more thorough and more efficient. Since megasonic and ultrasonic cleaning systems are contactless cleaning systems, they do not require the use of harsh cleaning chemicals or mechanical scrubbing as conventional cleaning methods do.

The ultrasonic andmegasonic cleaning system approach are also environmentally friendly, since neither use cleaning chemicals. In conventional cleaning methods, they require the application of an involved chemical disposal system to meet compliance with environmental laws.

Kaijo has been a global leader in the development and use of megasonic and ultrasonic technology for industrial applications for over 60 years.

Using Ultrasonic Cleaners in Disaster Restoration

Items recovered from disasters (like floods, hurricanes, and fires) are often covered with dirt, soot and mold. There are traditional cleaning methods for cleaning recovered items such as wiping, soaking in harsh chemicals or rough mechanical scrubbing. These methods may leave residue or cause damage to these items, while there's little assurance that they would come out completely cleaned.

Ultrasonic cleaning system is the ideal alternative to the traditional methods in cleaning these items.

This system works by generating ultrasonic waves and the tiny cavitation bubbles in the water (or water mixed with a mild detergent). The bubbles form and collapse in time with the frequency of ultrasonic waves. When these bubbles collapse against the surface of the items being cleaned, they create a strong cleaning and scrubbing action, knocking off and loosening dirt and contaminants from the surface.

One of the greatest advantages of ultrasonic cleaning over traditional cleaning methods is that the former cleans the items thoroughly – even items with complicated shapes and hard-to-reach holes and crevices. It cleans effectively and precisely, without the risk of damage to the items being cleaned.

Choosing the right frequency is the key for successful cleaning. For robust items with hard surfaces, opt for the low frequency (26 to 38 kHz) which produces large, energetic cavitation bubbles for the robust cleaning action. For cleaning delicate items, choose higher frequencies (450 to 950 kHz) which generates smaller bubbles for gentler cleaning.

Adding mild but specific solvents to the cleaning solution is required only for cleaning more stubborn dirt and contaminants. This is to ensure rapid and complete cleaning of the items.

Do you need to restore items after a natural disaster? Read the complete article “Using Ultrasonic Cleaners in Disaster Restoration” to learn how ultrasonic cleaners can help.

How Ultrasonic Waves Are Produced for Industrial Cleaning Applications

Industrial ultrasonic cleaners deliver cleaning performance that is faster, safer, and more efficient than traditional cleaning methods that use chemicals. Along with being more effective, this method is more environmentally friendly since cleaning doesn't require the use of harsh chemicals or mechanical scrubbing. Tiny cavitation bubbles generated by the ultrasonic system do the removal of impurities from a variety of parts and components, which range robust metal and ceramics to delicate semiconductors.

The three main components of the ultrasonic cleaning system consist of the ultrasonic generator, the transducer, and the cleaning tank.

The cleaning tank holds the cleaning solution as well as parts to be cleaned. It must be heavy and durable enough to withstand the cleaning action of the ultrasonic waves, and big enough to contain the biggest parts to be cleaned.

How doultrasonic cleaners work? The ultrasonic generator produces the electric signal which, in turn, generates the ultrasonic waves via the transducer.

The function of the transducer is to handle the frequency and power produced by the generator to create the ultrasonic waves in the cleaning solution. When the ultrasonic waves travel through the cleaning solution, it creates compression peaks and troughs. The tiny cavitation bubbles form in the troughs where there is low pressure and collapse in the peaks because of high pressure.

When the bubbles collapse, each of them releases a small but powerful jet of liquid, which produce an intense cleaning action on the surfaces of the parts being cleaned. This effectively dislodges any contaminants and any other impurities from the surface of the part being cleaned. The microscopic bubbles can clean even intricate shapes and hard-to-access holes and crevices. Result is fast and thorough cleaning.

Using Ultrasonic Cleaners for Medical Devices

Ultrasonic Cleaning Systems are often utilized to clean medical instruments, devices and implants that have delicate, high-precision designs and complex surface geometries. Medical devices typically have various sorts of contaminants and impurities that include carbon deposits, grease, chemical remnants, fungi and bacteria. Because of that, they often require thorough but also gentle cleaning at the same time – and ultrasonic cleaners are effective in addressing these requirements.

The technology used in ultrasonic cleaning systems employ the power of cavitation. When liquids are subjected to strong forces, they tend to fracture and form microscopic bubbles. When these small bubbles form and collapse (often millions of times every second), they create high temperatures and powerful impact over microscopic areas. These are the forces that are utilized by ultrasonic cleaners.

Ultrasonic cleaning systems use powerful high-frequency sound waves to agitate liquid placed in a cleaning bath or tank. This reaction causes cavitation bubbles to form. When medical tools are placed inside the cleaning bath, these microscopic cavitation bubbles form over the surface. As these bubbles form and collapse over the surface of the medical tools, they dislodge impurities from them, with pinpoint precision.

With an ultrasonic cleaning system, there is no need to use harsh chemicals or scrubbing that can undermine delicate medical devices and implants. Plus, it's also cost-effective and environmentally safe. Ultrasonic cleaners ensure a powerful, thorough but also gentle and safe cleaning process for delicate medical devices.

Both the CDC (Centers for Disease Control and Prevention) and the WHO (World Health Organization) recommend the use of ultrasonic cleaning technology for medical applications. Ultrasonic cleaners play a vital role to ensuring that medical devices and implants meet high levels of cleanliness.

How Medical 3D Printing Benefits from Ultrasonic Cleaning

Hospitals, medical research centers and facilities produce 3D printed models of human body parts or internal organs to create prosthetics for the purposes of surgical procedure, diagnosis, or for educational purposes. Industrial ultrasonic cleaners are now being used to ensure that parts manufactured for medical use are ready for use.

3D-printed models of human body parts and organs are made with build material. The support material, on the other hand, holds the build material until the latter has hardened and self-supporting, and then the support material must be removed to ensure model accuracy. This is where industrial ultrasonic cleaners are used to provide precise cleaning without damaging the material being cleaned.

The ultrasonic cleaning system uses a generator that produces ultrasonic electrical signal. The transducer, then, converts this signal into ultrasonic waves that travel through the cleaning solution inside the tank. Microscopic cavitation bubbles form from the waves, and then collapse in the pressure peaks.

The cavitation bubbles encounter the support material and effectively dislodge it from the build material. The great thing about ultrasonic cleaning is that it doesn't cause any damage to the build material that is being cleaned.

Depending on the 3D model being cleaned, Kaijo’s industrial ultrasonic cleaners can operate at frequencies delivering the precise cleaning strength. Lower frequencies (26 kHz or 38 kHz) produce larger cavitation bubbles which perform a more robust cleaning action on typical 3D models. For more cleaning delicate models or models with fragile material, higher frequencies (450 kHz or 950 kHz) are used to produce smaller bubbles which deliver a gentler cleaning action.

Medical 3D models benefit from ultrasonic cleaning. First, it does rapid and thorough cleaning of support material. Second, it is free from human errors. Third, no harsh chemicals or scrubbing is involved. And fourth, disposal of wastes doesn't require additional measures.

Kaijo can help hospitals and medical facilities realize the benefits of using ultrasonic technology with 3D printing.

Why Use Ultrasonic Cleaning Systems with a Heater?

Ultrasonic cleaning systems can remove a wide variety of contaminants from the surfaces of parts that need to be cleaned, however removing certain kinds of contaminants require more time than other cleaning applications.

The performance of an ultrasonic cleaning system depends on the parts to be cleaned and the type of the contaminants that have to be removed. For instance, robust parts like automotive components can be typically cleaned in plain water, using the strong cleaning action of the lower frequencies (which produce larger and more energetic bubbles for more robust cleaning). More delicate and fragile parts like semiconductor wafers are usually cleaned using higher frequencies (which produce smaller and less energetic cavitation bubbles for delicate cleaning).

But sometimes, cavitation bubbles alone are not enough to remove tough deposits such as oil-based dirt and grease. That's where additional measures like a mild detergent and heat come into the picture.

In some cases, a combination of a mild detergent and heat can be tailored to a particular object, and the proper selection can help in improving the ultrasonic cleaning system's performance significantly. The detergent increases the solubility of the contaminants while heat softens them. The heat increases the effectiveness of the detergent. These measures will help in removing these contaminants quickly and completely.

Kaijo’s ultrasonic cleaning systems consist of ultrasonic generators (which produce the ultrasonic signal and are selected depending on the frequency needed for the cleaning application), transducers (which should be matched to work with the selected generator), and a tank (which holds the bath and the objects to be cleaned in it).

For cleaning applications requiring heat, both the transducer and the tank should be designed for a heated cleaning solution. Typical temperatures range from 80 degrees Centigrade (or 176 degrees Fahrenheit). Kaijo’s ultrasonic transducers and tanks can accommodate heating requirements up to 100 degrees centigrade (212 degrees Fahrenheit) and the company will work with customers to select right equipment and systems from their full line of products.

How Ultrasonic Cleaning Systems Promote Profitability

Having an effective cleaning process is essential to many industries. In recent years many companies have made the switch from degreasing and other conventional cleaning processes to a more cost-effective cleaning approach.

The chemicals involved in the conventional cleaning process and are expensive to buy and also need to be safely stored. Another consideration for choosing a new cleaning method is the protection of workers who use these chemicals, plus the safe disposal of toxic waste adds further expense. Other industries need to find alternative cleaning alternatives due to environmental concerns.

In industries that require cleaning of industrial parts and equipment, ultrasonic cleaning systems have emerged as a preferred alternative to traditional cleaning methods. These systems utilize ultrasonic energy to clean contaminated tools or parts.

Ultrasonic energy works rather simply – when dense, elastic media such as water is subjected to high-frequency energy, it expands and contracts quickly as to cause millions of microscopic fractures or tears. The microscopic bubbles that are created form and collapse so quickly that they create a great force. When these bubbles touch close to the surface of an object, the force can knock the contaminants off the surface.

Ultrasonic cleaners consist of a tank that is usually filled with water. A transducer can generate high-energy ultrasonic frequencies between 20 to 200 kHz. When contaminated items are a placed in a bath inside the tank, the ultrasonic waves from the transducer generate millions of tiny cavitation bubbles which do the cleaning action. Depending on the frequency chosen, ultrasonic cleaning systems can do effective cleaning on all parts that range from machinery tools to delicate medical equipment.

Ultrasonic cleaning systems are cost-effective but are also a fast, powerful and safe choice for even the most challenging cleaning applications. It needs little supervision and does not require cleaning with chemicals or the need toxic waste disposal. Since there are very few moving parts ultrasonic cleaners require little maintenance as well.

How Utility Companies Cut Grease, Grime and Costs with Ultrasonic Cleaners

The large compressors are usually used by utility companies to move natural gas through pipelines into storage. The compressors themselves, as well as the engines that drive them, are exposed to a lot of grease, grime and deposits and thus require extensive cleaning and maintenance.

Many utility companies use conventional methods of cleaning those heavily and hardened grease- and oil-based components. However, industrial ultrasonic cleaners now offer a better alternative solution to traditional cleaning methods. They use powerful ultrasonic generators and transducers to generate microscopic bubbles in the cleaning solution. These bubbles act as “scrubbers” which cleans parts quickly and thoroughly.

Traditional cleaning methods use strong cleaning chemicals which may corrode or damage the surface of the parts being cleaned. Using industrial ultrasonic cleaners on the other hand only requires a gentle water-based cleaning solution to clean parts. A mild detergent may also added, and/or the solution can be heated if needed for cleaning off grease and oil-based materials.

Unlike manual scrubbing, microscopic bubbles generated by ultrasonic cleaners can reach inaccessible interior surfaces (such as holes, bolt threads and deep crevices) of the parts being cleaned. The result? When a part is submerged in the ultrasonic tank all surfaces are cleaned equally and completely.

Using industrial ultrasonic cleaners will significantly reduce the need to soak soiled materials in a harsh cleaning solution. Not only will ultrasonic cleaning system will save you time, it will also save you money as well. When machine parts are cleaned down to the bare metal throughout, maintenance is more effective, easier to carry out and provides improved reliability for the compressors and engines. Parts that are completely clean will usually have a longer life and extend the lifetime of the corresponding machines. Overall facility operating performance will be more cost-effective and energy-efficient.

Kaijo can help utilities realize the benefits of using ultrasonic technology. For more details read the entire article, “How Utility Companies Cut Grease, Grime and Costs with Ultrasonic Cleaners”. For a free consultation or quote call Kaijo at 408-675-5575 or email info@kaijo-shibuya.com.  

The Power behind Ultrasonic Cleaning Systems

Ultrasonic cleaning systems offer an ideal alternative to the traditional cleaning methods, which apply substances or physical contact such as using harsh chemicals or mechanical scrubbing.

But an ultrasonic cleaning system, as the name implies, uses sound rather than substance or scrubbing. It utilizes the principle of cavitation in cleaning contaminated tools and parts.

The principle of cavitation refers to a phenomenon in which disturbances in liquids lead to the creation of short-lived cavities bubbles of gas or vacuum. When the bubbles reach high levels of energy, the bubbles implode and generate a considerable amount of force. The impact created by the imploding bubbles powers the ultrasonic cleaning method.

An ultrasonic cleaning system consists of a tank fitted with a special loudspeaker (transducer) which generates the high-energy ultrasonic waves. As the waves pass through a liquid of water, they reach a desired level of disturbance which leads to the formation of millions of tiny bubbles. As these bubbles form and implode many times each second, they create the cavitation energy needed to dislodge dirt, grease, and grime of the article immersed in the cleaning tank. Despite being tough and effective in removing dirt because of the cavitation energy, these bubbles otherwise will not damage even the most delicate tools.

Kajjo’s ultrasonic cleaning systems offer versatile cleaning ability which are also cost-effective and energy-efficient. A unit has a transducer which produces ultrasonic energy that range from 20 kHz to 1.5 MHz.  These systems employ piezoelectric transducer technology which promises – and delivers – superior cleaning performance over a wider range than other technologies. Piezoelectric transducer technology is far more suitable for ultrasonic cleaning because it has the ability to create ultrasonic sound energy at very high frequencies.
