Choosing the Right Industrial Ultrasonic Cleaner Features and Options

Industrial ultrasonic cleaners can represent a sizeable investment.  Here we define these units, what to look for when purchasing, and offer equipment options to help you make the right selection.  Included are examples of industrial ultrasonic cleaner applications.

Industrial Ultrasonic Cleaner Defined

Industrial ultrasonic cleaners are heavy-duty cleaning systems designed for continuous operation and the effective removal of contaminants from large or numerous parts. The job to be done – not the size of the cleaner or items being cleaned – defines these products.

That’s why industrial units are available in benchtop and floor mounted configurations.

Heavy-duty ultrasonic parts washing usually means long-term (multi-hour) continuous cleaning operation.  This calls for capabilities such as heavier gauge stainless steel cleaning tanks, automatic time and temperature safety shutoffs, and other features/benefits described here. 

Key Industrial Ultrasonic Cleaner Features to Consider

Tank Capacity

Cleaning tanks are specified by dimensions (length, width, depth) and cleaning solution capacity. Key points to consider when selecting tank capacity:

• Parts must be fully immersed in cleaning solutions
• Parts should not contact each other or the tank
• Cleaning baskets, used in most applications, are smaller than tank dimensions
• Dividers and trays offer options for part separation in baskets

Large and/or heavy parts can be suspended in the tank or rest on specially constructed supports on tank bottoms offered on certain industrial units. 

Ultrasonic Frequency

Ultrasonic cleaning occurs when billions of microscopic vacuum bubbles implode against surfaces being cleaned to blast loose and carry away contaminants. 

• Lower frequencies such as 25 kHz produce larger bubbles.  When these bubbles implode they release strong cleaning energy.  For removing caked on grease, lapping abrasives or polishing pastes use a low frequency. 
• Higher frequencies such as 37, 45 and 80 kHz produce progressively smaller bubbles.  These are better for delicate, highly finished parts and those with complex surfaces, blind holes, cracks and crevices.
• Dual-frequency units allow you to broaden service offerings.

Industrial Ultrasonic Cleaner Operating Features

Unit size and operating frequency are two critical specification criteria.  Other features that may be important in helping you do the job most efficiently include:

• Temperature controls let you set cleaning solution temperature to the level recommended by the cleaning solution manufacturer.
• Timers control the duration of the cleaning cycle.  Some units are designed to start cleaning when the selected temperature is reached and shut down at the end of the cycle.
• Degas mode speeds the removal of trapped air in fresh cleaning solutions.  An alternative is allowing the equipment operate for a period of time without a load.    
• Sweep provides a slight ± fluctuation in the ultrasonic frequency and serves to even out the cleaning action to avoid “hot spots” or possibly damaging cavitation action, “dead zones” or no cleaning action, and harmonic vibrations that can damage delicate parts such as PCBs.  
• Pulse mode boosts ultrasonic power up to 20% to remove stubborn contaminants. 
• Dynamic mode optimizes cleaning results by automatically combining the sweep mode for uniform cleaning with the pulse mode that removes stubborn contaminants.
• Eco Mode provides gentle cleaning and a quieter operation, achieving a lower intensity cleaning cycle with sweep frequency.
• Adjustable Power lets you set the cleaning parameters to the job at hand.

Ultrasonic Cleaning with Volatile Solvents

Ultrasonic cleaning using volatile solvents such as IPA, acetone and toluene require precautions including meeting local and national regulations to avoid fire and explosions. The SOL XP series of explosion-proof ultrasonic cleaners in 6 tank sizes to 33 gallons help you meet these requirements.

Typical Applications for Industrial Ultrasonic Cleaners

The extent and type of contamination (i.e. dirt, gunk, greases and oils) to be removed may require longer cleaning cycles, pointing to the selection of a heavy-duty ultrasonic cleaner.  The following examples provide you with greater detail on when and how these units are used. 

• Automotive and power train cleaning and degreasing
• Cleaning costly plastic injection molds to maintain quality output
• Ultrasonic passivation for stainless steel to meet ASTM A967 standards
• Safely remove 3-D printing mold support
• Degreasing heavy parts
• Nondestructive testing of aircraft engine parts
• Cleaning new and reconditioned filters using flammable solvents

Marine engine repair, manufacture and sales companies rely on the marine industrial ultrasonic cleaner to remove dirt and contamination for their engine parts so that vessels run better and more efficiently. The marine environment is tough on large and small engine components, but ultrasonic cleaning works effectively on even the most delicate parts.

Marine industry business owners understand the need to keep marine engines, parts and components clean after manufacturing and repairs are performed. The marine industrial ultrasonic cleaner is a powerful and highly efficient and effective cleaning solution for the specific needs of the marine industry. Ultrasonic cleaners remove a wide range of build-ups and contaminants, gently yet powerfully, in order to preserve performance and extend the life of the parts and equipment.

Benefits of the marine industrial ultrasonic cleaner

Traditional cleaning methods require taking parts components apart and hand-scrubbing with chemicals harmful to both the environment and the workers cleaning the parts. With ultrasonic cleaning you will save time and money and limit vessel down-time because there is no need to disassemble equipment before cleaning. Ultrasonic cleaners use water-based cleaning solutions that are gentle on the environment and the parts and safe for workers. The life of your costly marine equipment will be extended. Through a process called cavitation, microscopic bubbles form from ultrasonic waves, then implode on the part’s components; thereby vigorously yet gently scrubbing and cleaning surfaces and crevices. Through its highly effective process, all of your large or small engine parts will look like new even if they were covered in tough to clean substances like salt, oil or grease. Ultrasonic cleaning can be used on-board for added convenience.

Ultrasonics can clean:

• valves, pistons and cylinder heads
• injectors
• tooling
• heat exchangers
• engine blocks
• fuel injectors and filters
• inboard and outboard parts
• circuit boards and computerized components
• plastic and rubber molding
• fabricated and machined parts
• diesel engine components
• subassemblies
• transmissions and drivetrains

Ultrasonic cleaners efficiently remove:

• salt deposits
• sediment and silt
• carbons
• varnishes and paints
• oil and grease
• metal shavings
• lubricants
• rusts
• carcinogens
• molds, mildew and algae
