How to Select an Industrial Ultrasonic Cleaner

Industrial and commercial ultrasonic cleaners can represent a sizeable investment. The global market, including industrial ultrasonic cleaners, is expected to reach $2.43 billion by 2028 according to Data Bridge Market Research.  The report states that this represents a CAGR of 5.85% between 2021 and 2028, and that “Rising industrialization and growth in the number of manufacturing industries will emerge as the major market growth driving factor.” 

The information in this article will help you select the correct industrial ultrasonic cleaner.

Defining an Industrial Ultrasonic Cleaner

The job to be done – not the size of the cleaner or items being cleaned – defines a commercial ultrasonic cleaner. Heavy-duty ultrasonic parts washing usually means long-term (multi-hour) cleaning cycles, which calls for more rugged construction including heavier gauge stainless steel cleaning tanks. These are available as benchtop and floor mounted units, which brings us to the first specification tip.

Ultrasonic Passivation for Stainless Steel

Ultrasonic passivation of stainless steel

Stainless steels such as AISI* Types 304, 310 and 316, are favored for strength and corrosion resistance.  Applications include food, chemical and pharmaceutical processing, surgical implants, architecture and transportation.  Over time starting from initial fabrication, free iron and other contaminants adhere to surfaces and must be removed. Ultrasonic passivation for stainless steel accomplishes this to meet ASTM** A967 standards.

What is Stainless Steel “Passivation?”

Machining and otherwise fabricating and handling stainless steel components may deposit iron particles and other contaminants (such as from machining or grinding tools) on the stainless steel.  These contaminants must be removed to forestall corrosion between the different metals once the stainless steel components are put into use.

Passivation removes these contaminants, forming a “passive” oxide film that becomes a chemically inactive or inert surface that enhances corrosion resistance.

Passivation vs. Electropolishing

There is some confusion between passivation and electropolishing as both relate to treating stainless … Read the rest

Ultrasonic Cleaner Degas: Why it’s Important

Ultrasonic Cleaner Degas

Getting the best results from your ultrasonic cleaner requires more than turning it on and immersing parts in the cleaning solution.  Whether using a fresh cleaning solution or one that has been idle for a period of time, an ultrasonic cleaner degassing procedure yields improved cleaning results.  Here we explain why and how the degas procedure is important.   

What is Ultrasonic Cleaner Degassing?

In a sentence, it is getting the air (a gas) out of your ultrasonic cleaning solution.

And why is that important?

Let’s start  with a simple illustration.  In the morning, the glass of water you placed on your night stand the night before (but did not drink) has bubbles adhering to the glass.  That demonstrates that water, a liquid, contains air. 

The same applies to ultrasonic cleaning solution formulations, especially but not exclusively those you dilute with water.  Examples include cleaning solution chemicals offered by iUltrasonic, our … Read the rest

Selecting an Industrial Ultrasonic Cleaner

Elmasonic xtra ST Ultrasonic Cleaners

If you have tough cleaning jobs characterized by heavy, tenacious contaminants or run cleaning cycles over long periods of time, regardless of part size, you should consider an industrial ultrasonic cleaner.  This post describes the various features and functions offered by industrial ultrasonic washers and how they contribute to achieving desired results. 

What is an Industrial Ultrasonic Cleaner?

You might think an industrial ultrasonic washer must be “big” because they handle industrial products.  Not necessarily so. Your industrial parts washer size (or cleaning solution capacity) is governed by the size of parts you are cleaning. Industrial ultrasonic cleaners are offered as benchtop and floor mounted models. 

Another consideration to keep in mind is the duration of your cleaning cycles.  ong-term cleaning cycles (i.e. operating … Read the rest

An Ultrasonic Gun Cleaning Tank Maintains Firearms

Gun Cleaning Solvent

Investments in firearms by individuals and organizations can be substantial. Here you will learn how to use an ultrasonic gun cleaning tank to maintain firearms.  It offers you guidance on when and how to use gun cleaning solvents and lubricants, explains why ultrasonic gun cleaning tank is a wise investment for maintaining firearms, and offers two equipment options for you to consider.

Gun Cleaning Solvents Described

Firearm owners may be aware of many gun cleaning “solvents” available on the market, but just what is a solvent?  According to the Encyclopedia Britannica, a solvent is “ordinarily a liquid in which other materials dissolve in order to form a solution.”

When it comes to maintaining firearms, gun cleaning solvents are generally employed just after a session on the shooting range or in the field.  Savvy firearm owners recognize the importance of cleaning and lubricating their weapon immediately after use using rods, … Read the rest

Ultrasonic Cleaners with Remote Generators

Ultrasonic Cleaners with Remote Generators

Industrial-scale ultrasonic cleaning involving flammable solvents with low flash points* requires special equipment as well as special procedures.  The American Chemical Society publishes a table of common organic solvents that includes flash points.  In terms of equipment specifications, you will need ultrasonic cleaners with remote generators to comply with NEC and NFPA as well as local codes to minimize dangers of fire or explosions.       

Ultrasonic Cleaner Generators – What they Do

Sol XP Ultrasonic Cleaner
SOL XP Explosion-Proof Ultrasonic Cleaner

Benchtop ultrasonic cleaners and most floor-mounted industrial-sized units used with non-flammable aqueous cleaning chemicals have self-contained ultrasonic generators mounted in the unit casing along with the ultrasonic bath tank, transducers, control panel and, if so equipped, heaters.

These generators power the ultrasonic transducers that create billions of microscopic bubbles that implode on contact with items being cleaned to blast and carry away contaminants.  For more on this see our post on how ultrasonic Read the rest

Using Acetone Solvent as an Ultrasonic Bath

Acetone, a solvent and thinner available in paint and hardware stores, carries on its container a warning that it is extremely flammable and quickly evaporates.  These two characteristics are always important to users but particularly important when acetone solvent is used as a degreaser in ultrasonic bath for residue-free removal of contaminants.  This post provides information on the safe use of acetone solvent as an ultrasonic bath.

But first, some background.

Why Caution is Critical with Acetone

Acetone and similar solvents such as toluene and IPA are characterized by relatively low flash points.  

A flash point is the temperature at which a particular organic compound such as an acetone cleaner gives off sufficient vapor to ignite in air when given an ignition source.  And as noted above, acetone evaporates quickly. 

The American Chemical Society publishes a table of common organic solvents that includes flash points.  Acetone’s flash point … Read the rest

Ultrasonic Cleaning Tanks: What You Should Know

Elmasonic Flex 2 Header

While a variety of ultrasonic cleaners are the market, one component they have in common is the ultrasonic cleaning tank where cleaning action takes place.  Whether you select a basic model ultrasonic cleaner, an advanced benchtop or a floor-mounted industrial-scale model, long-term reliability depends on the industrial ultrasonic cleaning tank and how you use and care for this essential component.

Ultrasonic Cleaning Tank Size

Cleaning tank size – which also governs the cleaning solution capacity – must be sufficient to accommodate whatever you are cleaning in such a way that parts are fully immersed in the ultrasonic cleaning solution.  

Although this may seem a no-brainer, remember that parts being cleaned must not be in contact with each other or the tank itself.  Otherwise, parts can be damaged, and perhaps more seriously, the tank itself can be damaged due to ultrasonic vibration. 

That is why most cleaning is accomplished in … Read the rest
