Green Cleaning With High Performance Ultrasonic Cleaners

Ultrasonic cleaning technology has proven to be an ideal choice for purging products of unwanted contaminants. High frequency sound waves in a liquid cause a cavitation which is key to cleaning away impurities. The lower the frequency means there will be larger pressure waves. The larger pressure waves results in larger bubbles. The downside of these high energy bubbles is the larger bubbles are less likely to penetrate into small cracks. The frequency is a paramount factor to determine how efficient an ultrasonic cleaner will function based upon your application. Ultrasonic cleaners which are equipped with adjustable frequency settings are often sought after depending on the requirements of product and situation. An ideal bubble size for most job tasks is generally 1 micron which is .00004 inches. This size bubble is generated from a frequency of 40kHz. However there are various advantages for utilizing lower frequencies. Applications involving cleaning engines, radiators or heavy duty metals usually require a frequency of 25kHz to adequately clean the product. This frequency allows for a strong cleaning force but could possibly damage weaker parts.

Typically the cavitations which ultrasonic cleaners produce have a circle structure. However, newer innovations in the ultrasonic field allow users to create other shapes such as rectangles. These breakthrough devices result in faster and deeper cleans. Manufacturers have also noticed there is less product erosion and higher reliability associated with this style of cleaning. There are still advantages for circle bubble however. The round shape results in a more uniform signal dispersion which minimizes distortion. Researchers are continuously developing newer and innovated ultrasonic cleaners which can transition easily between multiple frequencies.

A key advantage associated with newer ultrasonic cleaners is they are more spatial ultrasonic activity which results in a more uniform process and thorough cleaning without damaging delicate components. Fast liquid conditioning is important for switching between acoustic spectrums. Another advantage is there is a higher level of reliability and consistency of ultrasonic cleaner compared to manual cleaning. This consistency extends the longevity of products and utilizes less resources overall.

Ultrasonic cleaners are a staple of the “green” revolution and are an outstanding alternative compared to traditional cleaning solutions. Many older toxic solvents have proven to be unsafe for human contact as well as the environment. Due to these adverse affects a variety of toxics have become illegal resulting in many people switching to other cleaning processes such as ultrasonic cleaners. These machines actually save money in the long run due to cuts in time consuming labor. The faster operations allow many manufacturers to have quicker lead times which serves as a catalyst for faster product delivery. These high performance ultrasonic cleaners allow many manufactures to keep pace with today’s market.
