ROI, or Return on Investment, sounds like a daunting calculation, but it actually isn’t hard to figure out when you’re looking at buying a piece of equipment for your business, such as an ultrasonic cleaner. Also known as the “payback period,” ROI simply expresses when you’ll earn more money from the purchase of a piece of equipment than it cost you to buy it in the first place. [Read more…]
You have made the decision for your business to purchase an ultrasonic cleaner. Now that you have the basics of the machine that you want to buy it is time to take a look at some of the options that you can add to your machine.
While choosing all of the available options will surely give you a very nice cleaner, they may not all be necessary for you to have or use. Read on to find out which will work best for your applications. [Read more…]

When disaster strikes a home or business recovery can take a long time. Services like the Red Cross offer the basics of what people will need to get through their disaster, like food, shelter and emergency response. Others companies begin to help people put their lives back together in the aftermath of the disaster.
For years companies have been cleaning and restoring personal property contents for victims of all sorts of disasters. While traditional methods still exist, ultrasonic cleaners have taken a major role in disaster recovery.
The Traditional Way of Restoration
Traditionally companies that did this type of work did all the cleaning by hand. This meant having several workers using rags, chemicals, brushes and Q-tips in order to remove as much dirt, dust, mold and smoke damage as they could from recovered items. This process was very time consuming and often involved harsh cleaners and other chemicals. It was very limited in what it could recover in some cases. Even items that were restored might still have a mold or smoky smell to them.
Enter Ultrasonic Cleaning
The limitations of this process is why Omegasonics provides a better way for these companies to get their jobs done. Ultrasonic cleaners are well suited for contents cleaning.
In order to restore items that have been damaged in a disaster, cleaning time and effort must be spent getting all contamination removed. Smoke odors, mold, water damage and soot can find their ways into the smallest corners and openings in objects. While traditional cleaners are limited in what they can do based on the size of the brushes and where they will fit, ultrasonic cleaners can get anywhere and clean any part of an object no matter how small.
Ultrasonic Cleaning is a Better Way
Chemicals and brushes are limited in the amount of cleaning power they have. Detergents are there to dissolve the bonds between the dirt and the surface it is attached to, while brushes are there to remove the dirt once it has been loosened up. A brush can only carry so much energy; this means repeated passes to get things clean.
Ultrasonic cleaners use cavitation action to get items clean. Cavitation works by using very tiny, high-energy bubbles that crash into the surface of the object and blast dirt and contaminates away. Not only does this get items clean and looking as good as new, it also helps remove the odors that can be associated with fire and mold.
Ultrasonic cleaners also save time. What might take a team of workers an entire day to get through can be done in mere hours using an ultrasonic bath. This speeds up the time it takes to return these items to victims and helps them get back on their feet quicker.

In a previous post we examined the basics of ultrasonic cleaning, and learned how ultrasonic cleaners essentially “pressure wash” objects at the microscopic level. In this post, we take a closer look at the liquid medium used to transmit the ultrasonic sound waves and clean objects in industrial ultrasonic cleaners.
First, a brief review of ultrasonic cleaning. An ultrasound generator along with special transducers mounted to the bottom of a liquid-filled stainless steal bath, alternately compresses and expands the liquid between 25,000 and 130,000 times a second, depending on the application. This, in turn, generates bubbles, which collapse at high speed, increasing the temperature of the liquid and producing a high energy liquid stream which collides with the surface of the object being cleaned. Essentially, the object is cleaned with a high energy jet spray at the microscopic level.
The choice of liquid for can have a significant effect on the performance of industrial ultrasonic cleaners. While water is most often the choice for ultrasonic cleaning, plain water can be augmented with detergents, or even replaced with other solvents in certain applications.
Adding detergents lowers the surface tension of the liquid which reduces the energy required to form bubbles. This can dramatically increase the cavitation, or process by which the bubbles collapse producing the high temperature liquid streams which clean the surfaces. The increased efficiency in producing this cleansing agitation along with the inherent cleaning properties of the detergent results in increased effectiveness of industrial ultrasonic cleaners.
The choice of cleaning medium (called the “chemistry”) is critical to the effectiveness of ultrasonic cleaning. The substrate – or material to be cleaned – as well as the kind of contaminants to be removed, are key factors to consider in selecting the cleaning chemistry. While water or detergents dissolved in water are the most common chemistry used in industrial ultrasonic cleaners, other solvents might by better suited for particular applications.
Future posts will look at additional ways to increase the effectiveness and efficiency of ultrasonic cleaning.
