Ultrasonic Cleaning Technology Ultrasonic cleaning is a science which has not yet been recognized by the industrial educational community. Not a single learning institution in the country teaches courses on this vital cleaning Technology, yet every manufacturer in the world has needs for these cleaning systems. As a result, many individuals approaching Zenith for equipment rely totally on us to provide them with all of the answers. We at Zenith are more than happy to do just that. However, a good background on ultrasonic cleaning technology is vital before an educated purchasing decision can be made. In short, the ultrasonic cleaning systems produce scrubbing action through a process known as "cavitation," a physical process during which ultrasonic energy is emitted into a cleaning bath. Sound waves are composed of 2 components; an expansion cycle during which the liquid molecules are being pulled apart, and a compression cycle, during which the molecules are being compressed. If the expansion cycle of the wave has enough energy to overcome the surface tension of the liquid, a "cavity" is produced, a microscopic tear in the fluid medium which grows in size for the duration of the expansion cycle. Immediately following the expansion cycle, the compression cycle follows, rapidly compressing the cavities created, thereby producing millions of microscopic liquid jets which have been shown to travel at speeds exceeding 400 km/hr. As a result of the instantaneous collapse of the cavity, the liquid surrounding the cavity can heat to temperatures higher than that on the surface of our sun. This combination of physical scrubbing action and extreme temperature produces a cleaning effect which can not be outperformed by any other mechanical cleaning method for most applications. Parts which are submerged in the ultrasonic cleaning tank are continuously scrubbed by millions of imploding cavities which gently scrub the parts clean in the smallest recessed part areas and blind holes. When you contact Zenith, our engineers will take the steps necessary to educate you on the ultrasonic cleaning process to ensure that you understand WHY our engineers are recommending a particular product line, or option. Only then can one understand if and how an ultrasonic cleaning system can address your particular cleaning application. The links listed at left will provide additional information on the ultrasonic cleaning process, written in a manner which is understandable, and not utterly confusing. Combined, these pages will provide the average engineer with specific information on how ultrasonic systems operate, and how to maximize their performance. As you will see, there are many issues which can affect the process. Although this web site has been designed to include a good deal of information, even more is included in our full-color catalog which can be mailed to your attention immediately. ADDITIONAL INFORMATION LINKS The PART DESIGN link will describe how the design of the parts will affect the decision making process in the system designs. SWEEP FREQUENCY circuits have been used for decades to even out the scrubbing action produced by ultrasonic cleaners. Select this link for information on this circuit, which is included on every Zenith ultrasonic system. The CHEMISTRY link discusses the importance of chemistry selection, and what effects this has on the the cleaning process. OTHER ULTRASONIC CLEANER ISSUES describes the importance of temperature, detergent concentration, shadowing, and oscillation, all of which can greatly affect the ultrasonic cleaning process. We hope that this section provides you with information that you have not found elsewhere, and look forward to providing even more. Feel free to contact us at any time for additional information on the ultrasonic cleaning process, and equipment options.
