The preceeding blog discussed what is probably the “granddaddy” of all cleaning challenges – burned-on carbon.  But, as those of us who have been in the cleaning business since Noah launched the ark know, there are a bunch of other cleaning challenges that defy modern technology.  In general, these challenges fall into a small group … Continued

As a leading ultrasonic manufacturer, we are often asked to manufacture large, industrial ultrasonic cleaning systems producing a particular ultrasonic power density based on laboratory trials.  In fact, it may not be appropriate to base the watts per gallon requirement for a large industrial application on those found effective on a laboratory scale.  A paper at the following … Continued

It should be clear by now that heat plays an important role in drying.  Delivery of heat to a drying system is critical and can be accomplished in a number of ways.  Today’s blog will explore two options for heat delivery – conduction and radiation. Conduction seems to be the “go to” when it comes … Continued

High velocity compressed air blow-offs are a viable means of drying or de-watering parts in many applications.  They are especially useful if parts don’t need to be “super dry” (as completely free of water) or if there is a requirement to remove “excess” water from a part prior to final drying using another means such as hot … Continued

Deep in a file drawer in my office on a couple of pieces of paper yellowed by time is an article that, written and published in 1954, is a literal snapshot of the notion and perceived traits of an engineer over 50 years ago – when I was only 9 years old.  Every once in a … Continued

Well, sometimes stuff happens!  As I was checking the blog today I discovered that the wrong sound clip somehow wormed its way into yesterday’s blog Sounds of Silence – Pulse Period and Duration I have made the appropriate correction and now the sound clips in the published blog are actually the ones that they should … Continued

Using a slow rate of pulsed ultrasonics is an excellent way to speed the degassing of liquids in preparation for use in ultrasonic cleaning and rinsing applications.  The blog Ultrasonics – How to Degas Liquids explained the mechanism by which dissolved gasses are extracted from liquids by ultrasonic cavitation.  Although this degassing mechanism is very effective … Continued

A previous blog Ultrasonics – Degassing – What Gas? and Why? revealed why dissolved gas is detrimental to ultrasonic performance.  This blog will describe various ways in which dissolved gas can be minimized and eliminated to facilitate ultrasonic cleaning.  Since the most common liquids used in ultrasonic cleaning are water and water-based solutions, the following applies … Continued

Just about everyone is familiar with the term “hard” water but few know what it really means.  In this blog I’ll try to explain what “hard” water is and why we prefer water that is “soft.”  In the blog It’s Time To Talk About Water – Again, items 2 and 3 in the list of water contaminants … Continued

The blog It’s Time To Talk About Water discussed the variations in water from different sources.  Today’s blog is the start of a series on how to purify and prepare water for use in cleaning and rinsing applications. Water from municipal and other sources may have characteristics that are deleterious to a variety of processes.  Many of … Continued
