Multiple Frequencies Maximize Ultrasonic Effectiveness

In our last blog we explored a fundamental phenomenon related to ultrasonic cleaning: frequency.  We arrived at the observation that lower frequencies produce relatively larger and higher energy cavitation bubbles, and higher frequencies produce smaller bubbles that are able to penetrate into smaller areas.  We saw that the most common frequency compromise between scrubbing power and cleaning penetration is found at 40khz.

However, while this is certainly one good takeaway from the study of frequency in ultrasonic cleaning applications, UPC wanted to come up with a solution that worked well to incorporate multiple frequencies into the cleaning process, to better take advantage of the different ways in which the different frequencies work.  The result is our Vibra-Bar®technology that reliably produces multiple frequencies simultaneously (Simultaneous Multi-frequency®).  While the advantages of such an arrangement may be apparent, the technique for the creation of these frequencies is less readily so.

The typical shape of a vibrating membrane to produce sound waves is a circle – think drum heads, and audio speakers.  The advantage of a round shape is that it produces a more uniform signal dispersion to minimize distortion.  However, for cleaning purposes (that are out of range of the human ear), distortion is actually desired because it is the very presence of multiple resonant frequencies that is advantageous.  The rectangular shape of our Vibra-Bar® and its structural design allows Simultaneous Multi-frequency® resonance even though only one (40khz) is supplied to the piezoelectric stacks.  This happens because of the complex resonant properties of a three dimensional rectangle shape, when driven by two separate piezoelectric stacks.

The technology behind UPC’s flagship product is certainly complex, but the results are clear: faster operation, deeper cleaning, less erosion, higher reliability, and wider range of cleaning capability.  At UPC, we’re continually pursuing new and innovative ways to help our customers get the most out of this technology, and our Vibra-Bar® design providing Simultaneous Multi-frequency® is just a manifestation of that pursuit.

Ultrasonic Cleaning: Frequency ranges and Applications

Now that you have read information on the UPC website, and our previous Blogs, you likely have a good feel for the basics about the technology behind precision ultrasonic cleaning.  There are many different aspects of the cleaning process that are application-specific and technically complicated, but for the purposes of this blog, let’s explore just one important aspect: frequency. High-frequency sound waves introduced into liquid to create cavitation, effectively scrub contaminants from the targeted parts in a cleaning tank.

A Closer Look at Cavitation

There are many technical papers written on the subject of cavitation, including some with respect to minimizing the adverse effects of cavitation in relation to propeller design.  Yet, at UPC, rather than finding ways to circumvent the adverse phenomenon, as those in the marine industry seek to do, we’re seeking to take advantage of cavitation by manipulating the amplitude and frequency of sound waves to make it work in useful ways, to promote precision ultrasonic cleaning.

Characteristics of the phenomenon of cavitation change as a result of the frequency at which the rarefaction and compression of the wave occurs.  The key concern is the size of the bubbles created – the lower the frequency, the larger the pressure waves. The larger the pressure waves, the larger the bubbles.  Larger bubbles create greater energy, and so bubble diameter size and ultrasonic frequency is an inverse relationship; the ultrasonic energy produced by cavitation (scrubbing) increases as frequency decreases.

One related point to consider is that while larger bubbles have higher energy output, they have less potential for cleaning penetration in small cracks, crevasses and blinds because of their size.  The frequency that is most often used as the ideal compromise between power and penetration for ultrasonic cleaning is 40kHz, which creates a cavitation bubble with a diameter of approximately 1 micron.  For industrial applications involving heavy mechanical equipment such as cleaning engine blocks, radiators, dies, and other metals where the finish isn’t a critical consideration, 25khz is often used – a lower frequency, a more powerful cleaning technique, but potentially destructive if used in the wrong parts cleaning applications.  Accordingly, for more delicate operations, such as precision optics, hard drive parts, and the like, 68kHz is another common frequency.  On the higher end of the spectrum, 170kHz is occasionally employed, often for pharmaceutical products, medical implants, and titanium components.

In our next blog, we will explore some other techniques that we employ (and have patented) for optimal application of much of the information we have covered here.  Be sure to check back here for our next blog – and in the interim, tweet @ultrasonicpower or visit our website to get in touch, – we would love to hear from you.

It’s Music to Your Instrument Tech’s Ears

As any musician will tell you, keeping their instrument clean and in top working order is vital to the integrity of the performance, and for the longevity of the instrument – neglected instruments, or those that are cared for rarely or poorly won’t perform well, and won’t last as long.  Here at Ultrasonic Power Corp, we do a lot of business with various musical instrument manufacturing and repair companies, and with school music programs, because they have seen enormous benefits using our technology for their cleaning processes for brass and woodwind instruments.  One current example of our involvement in the industry is our participation in the annual Texas Bandmasters Convention, which began yesterday, and ends Wednesday – If you’re here, stop by booth #2101 and say hello!  We’d love to talk to you, and to tell you more about our cleaning solutions for your band.

As we mentioned in our previous blog, there are certain safety benefits to using ultrasonics – specifically for instrument cleaning applications, using ultrasonic eliminates the need to use harsh chemicals in the cleaning process, which has a double benefit: the risk to the repair technician is eliminated, as they no longer have to handle harsh chemicals, and the musician is also no longer at risk of ingesting any leftover chemical dip residue that could potentially reside on instruments after a chemical cleaning process. Additionally, the cleaning time is dramatically reduced – with a chemical cleaning, the process can take more than an hour, but with ultrasonics, a range of about 2-5 minutes is standard.

One of our clients, Adam Martinez, was particularly happy with his purchase.  Adam is the manager at High School Music Service in San Antonio, a local music store and repair/restoration center for local musicians and schools.  He recently purchased a 90 gallon unit from us, and hasn’t looked back.   His previous cleaning process, which included degreasing, a chemical dip, and a final manual brushing, has been totally reorganized:  The chemical dip, which had a tendency to damage the lacquer finish on some instruments has been eliminated.  The degreasing is no longer necessary.  The need for manual brushing has been eliminated.  In short, his cleaning time has been cut in half, and he no longer has to spend money on the chemical cleaners, or worry about regulations for their disposal.

As a general rule, ultrasonic cleaning is safe and effective for all types of brass, nickel, and other metal instruments.  Repair technicians will know the details of other instruments or parts of instruments that can also be cleaned with ultrasonics – things like clarinet keys, and other woodwinds.  Individual instruments will have different levels of disrepair, or other anomalies that technicians will be able to ascertain.

Taking care of musical instruments is important, and we’re glad we can offer a great solution to our customers.  If you’re curious to find out more, our website has a lot of good information, and feel free to contact us via phone, email, or social media to talk specifics with our experts.  We hope to hear from you!

We are also just a few days out of June, which was declared National Safety Month by the National Safety Council – but we think that every day should be a safe day!  All this provides a fitting backdrop for a discussion on the safety-specific merits of ultrasonic technology, and how they could help your employees, the environment, and your bottom line.

Whatever part you’re cleaning, whether it’s a gun, greasy engine parts, a smoke-damaged electronic device, or less-than-shiny trombone, traditionally that cleaning involves different toxic cleaning chemicals and solvents.  With any hazardous materials come several complicating factors – personal protective equipment (PPE) for proper handling and application, safety training standards, Safety Data Sheets (SDS) documentation, environmental disposal permits, and emergency procedures for spill or incident response.  From the perspective of employee health risk exposure, ultrasonic technology improves processes by eliminating risk exposure to toxic chemicals, and eliminating the risk of contamination, or spill incidents.  Ultrasonic cleaning technology is more “green” as for this reason – no more use of harsh chemicals and solvents or potentially improper or unsafe disposal.

If your business involves chemical cleaning, one safety consideration you should investigate is an investment in ultrasonic cleaning technology. Do the numbers, the Return on Investment for an ultrasonic solution can be impressive. Consider safety a value in your business ROI, as we do here at UPC and contact us today for more information about our safe and effective ultrasonic cleaning technology solutions.

Ultrasonic Power Technology: On the Frontlines of the Clean Drinking Water Battle

Bangladesh, China, Ghana, Haiti, and scores of other countries face a daunting task of providing clean and safe drinking water to their citizens.  Often thought of as a developing world problem, there are countries like China that are finding that toxic waste from the country’s burgeoning factories are polluting rivers and lakes that are the source of drinking water for its people.  In fact, in a dramatic challenge, a leader of the Chinese environmental protection agency was offered a large sum of money to take a swim in a local river that is heavily polluted.  Despite the monetary reward, the official declined due to his fear of the river’s pollution and toxicity.

Even in the United States there are many examples where water sources such as wells, rivers, ponds, and even lakes have become contaminated with unhealthy amounts of various elements like mercury and arsenic due to mining accidents, bacteria from sewage back-ups, or toxic substances from small and large industrial catastrophes.  It is clear that having access to clean drinking water is something we all have in common and an issue for the majority of the global population.

Fortunately, there are many businesses and organizations that are working to change this growing problem.  Charitable groups like The Water Project and Charity: Water are focusing attention on the problem and providing solutions that work to provide clean drinkable water, by maintaining the quality and potability of their local water sources.  On the private side, many businesses and industry sectors are developing products and services to alleviate the problem.

Ultrasonic Power Corporation is happy to be a part of the solution in this ongoing struggle.  One of our Canadian customers, an OEM, has utilized our ultrasonic technology to create a water filtration system for Canadian municipalities.  This system enhances the quality and potability of the city’s water system.  The company has been successful in implementing the filtration systems by utilizing Ultrasonic Power’s cleaning technologies.  This technology aids in the disintegration of biological cells such as bacteria that can be found in water.

Ultrasonic Power Corporation’s mission is to provide cleaning solutions for our customers and we are proud that our technology is on the frontlines of technology to create clean, quality, and potable water.

Ultrasonic Gun Cleaning Technology

As a gun owner, cleaning your weapon is as important as knowing how to discharge it safely and how to properly store it.  An important aspect of gun ownership is routinely cleaning your gun for both safety and preservation of the firearm.  Guns and gun ownership is personal and so too are the many opinions for maintaining guns in pristine readiness, including method(s) to clean a gun. While these methods have their proponents; we believe that using Ultrasonic Gun Cleaning Technology is the best way to achieve precision cleanliness.

With two sizes to choose from – HG 1206 for handguns – LG 3606 for rifles, the Ultrasonic Gun Cleaning Technology uses our patented Vibra-bar® technology.  This technology is the most advanced transducer design in the ultrasonic cleaning industry.  It provides multi-frequency waves for cleaning all surface areas of any weapon.  With the Ultrasonic technology, guns also receive Simultaneous Multi-frequency® and UP-Sweep TM technologies that provide both high performance cleaning, as well as an overall safe cleaning environment.

The benefits of Ultrasonic Gun Cleaning Technology include a high level of cleanliness, reduced cleaning time, complete lubrication of the firearm, and decreased drying time.

Cleanliness:  Because the technology is almost hands-free, there is very little prep and clean-up needed for a firearm to be deep-cleaned down to one micron.

Cleaning Time:  With less prep time, you already have saved time, but in addition to this, the overall cleaning time is 3-5 minutes for most weapons, unlike manual cleaning that can take up to an hour or more.

Lubrication:  The Ultrasonic Gun Technology has a lubrication tank designed to use ultrasonic energy.  This unique design provides complete coverage of the every surface of the firearm.  Areas that are difficult to thoroughly lubricate such as the barrel, magazine catch, hammer, and cylinder are easily coated with gun oil.

Drying Time:  Utilizing a hot air dryer that blows 29,250 cubic feet per minute of hot filtered air reduces total drying time for most weapons by 80% compared to other methods.

In addition to these benefits, other aspects of our cleaning technology are integrated to provide the best cleaning environment for most weaponry.  These other attributes include a cleaning detergent that is specifically chosen for weapon cleaning, as well as a rust prohibitor to protect the firearm from oxidization and other harsh elements.  In addition, the lubrication portion of the cleaning technology has been formulated for gun cleaning with both water displacement and low temperature properties.

Our products are made in America and have our full backing.  Ultrasonic Power Corporation provides the best warranty in the industry for this type of product.  If you ever have questions or concerns, you can speak directly with our staff that designed and built the system.  There is no middleman involved when it comes to addressing your concerns and questions.

We are excited to have this technology available for gun owners and will be exhibiting it at the 142nd National Rifle Association Annual Meeting from May 3rd to the 5th.  If you are at the meeting, please stop by Booth #5062 to visit with us and learn more about the Ultrasonic Gun Cleaning Technology.  We’ll be happy to tell you more and show you our product.

Ultrasonic Power Corporation today, launches a new Blog. Our purpose is to educate businesses about the technology, applications, and equipment. We believe in transparency and lifting the curtain on marketing hype because an informed customer is our best spokesperson.

Today’s businesses continually seek performance improvement in a hyper-active competitive world. The phenomenon of ultrasonics was first observed during the early part of the 20th century. Yet, the benefits of industrial cleaning applications were not fully realized until the early 1960s. As businesses entered the  21st century, their relentless pursuit of productivity, safety and health, to be good corporate stewards by producing sustainable products and services and naturally increase profitability, caused a serious look at ultrasonic cleaning technology. Today’s industrial grade ultrasonic cleaning systems operate at frequency ranges from 18kHz to over 170 kHz.  Typically, during the early years of industrial ultrasonic cleaning, most of the cleaning applications operated at frequencies of 25 to 40 kHz. With ever more sophisticated products, and an expectation by governments and communities for environmentally safe manufacturing processes, businesses have turned to precision industrial ultrasonic cleaning systems to deliver these expectations as well as boost productivity and profitability. Ultrasonic Power Corporation, has since 1972, been an innovator and leader in delivering industrial ultrasonic cleaning technology to customers globally.

Ultrasonic Power Corporation is focused on customer satisfaction and technological leadership for precision ultrasonic cleaning systems  while continually enhancing the ultrasonic technology to help our customers’ business achieve higher cleaning performance.
