How Ultrasonics Work

Dirty items come clean in ultrasonic cleaning systems when millions of superheated bubbles scrub grime and oxidation away with stunning results. How? Through the process of de-cavitation.
Ultrasonic cleaning systems send high frequency sound waves ripping through an ultrasonic cleaning solution leaving superheated bubbles in the waves’ wake. When these bubbles (aka cavitation’s) collapse (de-cavitation), the heat and energy of their implosions work with the specially formulated ultrasonic cleaning solution to remove dirt, oils, residue, and oxidation from the surface of the contaminated item. Imagine the ability to get into the tiniest of nooks and crannies where dirt and grime hide, and then imagine scrubbing that surface ultra clean. With conventional cleaning – brushes, rags and elbow grease – this task seems impossible. But the cavitating cleaning action of an ultrasonic cleaning system does just that – It goes where brush bristles can’t.

What is Ultrasonic Cleaning Technology?
Ultrasonic cleaning technology is high frequency sound waves creating a phenomenon in a fluid called cavitating action, or cavitations. Cavitations, the superheated bursting of bubbles in a fluid, are what make ultrasonic cleaning work.

How Can Sound Waves and Ultrasonic Cavitations Clean?
When a sound wave travels through fluid, it stretches and compresses the fluid to transmit sound. When the sound wave’s amplitude increases to a threshold level, when the fluid cannot hold the “stretch” of the sound wave, the sound wave energy literally tears the water apart and vacuum bubbles are formed. Each vacuum bubble grows in size until it can grow no more – equilibrium is reached between the bubble and the fluid – at equilibrium, the bubble is compressed by the surrounding fluid pressure until it collapses. At collapse, a tiny liquid jet is created in the bubble’s place.
Each liquid jet creates estimated temperatures and pressures of over five thousand degrees Celsius and ten thousand PSI when the collapse occurs. The extreme pressure and temperature of the jet provides the phenomenon responsible for the effective ultrasonic cleaning action. This action occurs millions of times, over and over, while the sound waves are traveling through the fluid.

Ultrasonic Cleaning Cleans Every Nook and Cranny
When the item being cleaned is submerged in the ultrasonic tank’s fluid, the millions of jets created by ultrasonic energy are capable of reaching into fine depressions and intricate details. Every surface area is exposed to the ultrasonic cleaning action; cracks, crevices and hard to reach corners of every nook and cranny get cleaned by the ultrasonic cavitating action. Ultrasonic sweep cleaning technology enhances the system’s ability to clean.

Ultrasonic Sweep Cleaning Technology
Ultrasonic sweep cleaning “sweeps” multiple ultrasonic frequencies through a single ultrasonic tank. This sweeping controls the creation of standing waves, allowing no single frequency to resonate in the tank thus eliminating the root cause of standing waves, and tank dead spots.

Ultrasonic Cleaning Power and Frequency
Ultrasonic system power is rated in how much energy, in watts, is generated in the ultrasonic tank. Higher power systems generally mean shorter part immersion times in the fluid.
The ideal cleaning frequency is determined by the size of dirt being cleaned. Simply speaking, higher frequencies are more capable it is of removing smaller particles, lower frequencies are better suited for large dirt particles.

Before You Start Cleaning

CAUTION

•  Do not place parts or containers directly on the bottom of the cleaning tanks; use a tray or wire to suspend items.
•  Do not allow the solution to drop more 1 ½” from top of tank.
•  Do not ever use alcohol, gasoline or flammable solutions. Doing so could cause a fire or explosion. Use only water-based solutions.
•  Do not ever use mineral acids. These could damage the tank.

Failure to comply with these cautions will void your warranty.

should reach operation level line (one inch from the top)
3| Add cleaning solution to the tank of water
4| Plug the cleaner into a ground outlet

Attention
Machine shuts down automatically if not in use for a prolonged period of time

Operating Your Cleaner

1. Plug in your machine and flip on the On/Off control switch in the back of the unit.

2. Fill the machine with your water/chemicals. Pay close attention to the directions for temperature and duration from the chemicals SDS information paperwork (Included in your package or available on our website).

3. Remove the basket put the lid back on the unit..

4.  First set the desired temperature by pressing the up arrow “temperature button” Second set the ultrasonic cycle time by pressing on the time up arrow “time button”. After setting the temperature and the time, press the ON/OFF middle button to start the unit.

5. Keep the basket out and the lid on while it is heating up to quicken the waiting period. You can also run the ultrasonic for an additional 10
   degrees per hour.

6. Place the basket back into the unit with parts for cleaning.

7. When the cleaning cycle is complete, you can rinse the parts in the sink, and dry. Strain the chemicals with a cheese cloth to keep them fresh for the next cleaning. If you are removing oils, you can find an “oil diaper” online for reasonable price and quantity. This can be placed on the water surface and will absorb the oils. This way the parts will not be coated again once the cleaning is complete. We do not offer the cheese cloths or the oil diapers.

AUTOMATIC DEGAS / SWEEP TECHNOLOGY
This unit has automatic degas and sweep technology, the first 5 minutes of usage. The Degas will expel all the gasses and/or air out of the water in the tank, for better cavitation for the ultrasonic power. The Sweep will move the cavitation around in the tank in a more uniform fashion making the ultrasonic cavitation more efficient.

Draining Your Cleaner

Warning Do not immerse the cleaner in water. Unplug the cleaner from the power source.
2L, 3L, 4L, and 6L models do not have a drain. To empty, use the side of the rim to pour the used solution into a waste disposal unit, rinse the tank thoroughly and refill with new solution.

Optimizing Your Cleaner

• Cleaning – check the tank for contamination whenever you change solution. If necessary, remove contaminants with a nonabrasive cloth and water.
• Emptying – always unplug the cleaner before emptying the tank. Empty the solution into a waste disposal unit.
• Filling – always unplug the line cord before filling the tank. Fill the cleaner to the operating level (one inch from the top with beaker/tray in place), using warm tap water. Low solution level – will cause the cleaner to fail. When you remove heavy or bulky loads from the cleaner, the solution level may drop below the operating level. If so, be sure to replace lost solution and degas, if necessary, depending on the amount used.
• Overload – do not rest any items on the tank bottom. Weight on the tank bottom dampens sound energy and will cause damage to the transducer. Instead, use a tray and/or beaker positioning cover to support all items. Allow at least one inch between the tank bottom and the beaker or receptacle for adequate cavitation.
• Covers – allow the cleaner to heat up to a higher temperature, faster and reduces excessive liquid evaporation.
• Heater – the heater may cause some discoloration of the tank wall. This is normal and will not affect the performance of the unit.
• Solution – the fastest method to heat your cleaner is to fill with warm solution, use heat, ultrasonics (which also adds heat), and a cover.
• Solution activity – the amount of visible activity is not necessarily related to optimum cavitation for cleaning.
• Degassing – fresh solutions contain many dissolved gases (usually air), which reduce effective ultrasonic action. Although solutions will naturally degas over time. Solutions that have been sitting unused for 24 hours or longer have reabsorbed some gases
• Heat – increases the chemical activity of cleaning solutions.
• Surface tension – can be reduced by adding solution to the bath. Reduced surface tension will increase cavitation intensity and enhance cleaning.
• Solvents – never use solvents. Vapors of flammable solutions will collect under the cleaner, where ignition is possible from electrical components.
• Renewal – replace cleaning solutions often to increase ultrasonic cleaning activity. Solutions, as with most chemicals, will become depleted over time. Solutions can become contaminated with suspended soil particles which coat the tank bottom, inhibiting ultrasonic activity.

Application Hints

• First time cleaning – first experiment with one piece, then proceed with the remainder.
• Solution level – Be sure to maintain solution level within 1 ½” of top of the tank. Surface activity can vary with liquid level.
• Load size – It is faster and more efficient to run several small loads rather than a few big loads.
• Placing items – Never allow items to sit on the bottom of the tank. Always place them in a tray or beaker or suspend in the solution.
• Rinsing items – After cleaning, use a clean water bath to rinse away chemicals adhering to items.
• Lubricating items – When necessary, re-Iubricate items immediately after cleaning.
• Drying items – Air drying at room temperature works for some items. Place parts requiring faster drying time under hot air blowers or in ovens.

Cleaning Methods

There are two methods of cleaning – direct and indirect. Each has advantages and disadvantages. When in doubt, run test samples using both methods to decide which one produces the best results for you.

Direct method

•  Items in perforated insert tray
•  Item suspended

How it works:

•  Fill the tank with warm water and a cleaning solution.
•  Place the items to be cleaned in a perforated tray and lower them into the tank. You can also suspend items on a wire and then immerse them in the solution.

Indirect method

•  Items laid randomly in solid insert tray
•  Items placed in beakers

How it works:

•  Fill the tank with warm water and a cleaning solution.
•  Pour your solution medium into one or more beakers or into a solid insert tray.
•  Place the beakers in a beaker positioning cover or a solid insert tray to fit your cleaner. Beakers should not touch the tank’s bottom.

The advantages of this method are:

•  Removed soil stays in the beaker or tray so you can easily examine, filter or discard it.
•  You can use one or more solutions at the same time.
•  Two completely different cleaning solutions.
•  One beaker or tray with a cleaning solution and one with a rinse solution.
•  Cleaning solution in your tank needs to be changed less often.

Cleaning Solutions

Solution Types
Water-based solutions are either slightly acidic or alkaline. They include detergents, soaps and industrial cleaners designed to remove specific soils. Acidic water-based solutions: remove rust, tarnish or scale. They range from mild solutions that remove tarnish, to concentrated, and inhibited acidic solutions that remove investment plaster, milk-stone, zinc oxide and rust from steel and cast iron as well as smut and heat-treat scale from hardened steel. Alkaline water-based solutions: include carbonates, silicates and caustics. These cause emulsifying action, which keeps soil from redepositing on the cleaned surface, and improves cleaning action in hard water.

base buffing and polishing compounds, milk residues and carbohydrates.
Heavy-duty| Mill scale; heat-treat scale, corrosion or oxides.

Change the cleaning solution periodically. Cleaning solutions can become contaminated with suspended soil particles which coat the tank bottom. This coating dampens the ultrasonic action and reduces cleaning efficiency. Certain solutions will cavitate better than others. Contact your local distributor for further information.Heat and cavitation: increase the chemical activity of cleaning solutions. Some materials may be damaged by this stronger chemical action. When in doubt, test run samples of items to be cleaned. Caustic solutions: used to remove rust from steels, metal alloy corrosion and a variety of tenacious soils.

Solution Amounts
Solution amounts may vary. The amount you use depends on the detergent and the type of soil to be removed. Follow instructions on the solution container and refer to the table below for the effects of solutions on metals.
