How Much Chemistry – Liquid

Using the right amount of chemistry is important to successful industrial cleaning.  Since there is no standard convention for expressing the amount of chemistry to use, it sometimes takes a little effort to sort things out.  Chemistry is supplied in either liquid or powder form with several different conventions for each.  Let’s look at liquids …

Hot Air Drying – Tips and Pitfalls

Drying is the last and often a critical part of a cleaning process.  In many cases it is also the most time and energy consuming.  It is often the most difficult part of the process to specify and control.  Although there are several drying technologies available, blowing with hot air is simple and by far …

Stainless Steel Compatibility

With its well-deserved credentials for chemical resistance and durability, stainless steel and particularly 316 grade stainless steel is a “go to” for the fabrication of ultrasonic cleaning tanks.  Although it performs well in most applications, there are still those where stainless steel has its limitations.  Stainless steel achieves its “stainless” characteristic by developing a very …

Ultrasonics – Near Field and BEYOND!

The term “near field” is not new to ultrasonic cleaning.  In general, it refers to cleaning parts in near proximity to the ultrasound source.  It is well known that increasing ultrasonic power density can produce improved cleaning results in many cases.  Increasing power density can be accomplished by reducing the size of the cleaning vessel to …
