Ultrasonic Cleaning Solutions

There are a wide range of components and solutions for ultrasonic cleaning in a liquid bath or special reactor cleaning applications. System solutions may be grouped as follows:

High Volumetric Power Systems and Standard Baths: Such systems are used when it is important to deliver uniform and homogenous ultrasonic energy over a large surface as found in standard bath systems. Using transducer elements with a large radiating surface the power density is usually on the order of 0.5 to 2 Watts per square centimeter. Such power is providing very good cavitation effects and uniform power distribution throughout the liquid bath or special cleaning chamber.


Through the use of plate mount transducers, submersible box transducers, tubular arrays, or a single-transducer with an integrated resonating bar or tube, standard bath systems or custom solutions that adapt to an existing cleaning process could still be provided. Both fixed frequency systems and wideband frequency systems use unique MMM technology.

Advantages of wideband MMM technology include:

¡ïUniform distribution of ultrasonic energy throughout the bath.
¡ïWideband frequency modulations create a wide range of cavitation bubble sizes offering faster and more thorough cleaning of parts.
¡ïComplex MMM modulations eliminate standing waves to improve parts cleaning and reduce damaging hot cavitation zones.
¡ïReduction of standing waves reduces transducer pitting and extends operational life.
¡ïFaster liquid conditioning and degassing of fresh cleaning solutions.
¡ïAdjustable inductive compensation, available on OEM modules, allows simple adaptability to 3rd party transducers and the possibility for field upgrades to existing systems.
¡ïMMM generators can drive multiple high amplitude clamp-on transducers to make unique radial cleaning chambers of any diameter or length.

High Surface Power Systems are available for ultrasonic cleaning applications where it is desirable to deliver extreme or high ultrasonic power to a focused area. Probes may be designed to deliver maximum acoustic power to the tip face where amplitudes are greatest or we can offer probes providing a combination of radial energy along the sides of the probe in addition to high axial power at the end tip face. Probe tip surface power density can be in the range of 10 w/cm2 to hundreds of w/cm2. This high power ultrasonic energy from the probe tip gives the added benefit of strong acoustic streaming that is directed outward in a straight tight pattern. Advantages in cleaning applications include:

¡ïIntense acoustical pressure at the probe tip generates a combination of ultrasonic cavitation plus strong mixing and streaming liquid currents.
¡ïThe strong acoustic streaming energy helps to break apart large flocks and surface contaminants allowing the combined cavitation to further act on smaller particles and exposed surfaces.
¡ïStrong acoustic streaming allows cleaning of problematic parts with very small holes or cavities. Gas bubbles trapped in small holes prevent entry of cleaning solution and hinder cleaning. Normal ultrasonic baths that rely only on cavitation may not drive air bubbles from small and long holes. Strong acoustic streaming acts to drive the air bubbles from the void allowing the cleaning solution to enter.

There exits offers the industry¡¯s one and only effective solution for ultrasonically assisted extrusion and drawing applications. The patented MMM ultrasonic generators have the unique ability to apply high power ultrasonic energy to large mechanical systems like extruder heads and drawing dies.

In these applications the key benefits to ultrasonic vibrations are:

¡ï Friction reduction between the tool and the extruded or drawn material

¡î Improved Material Flow
¡î Reduced Pressure
¡î Faster Extrusion or Drawing
¡î Less breakage in a drawing process improves production yield.
¡î Improved surface quality of extruded or drawn material.

¡ï In some processes the material structural characteristics may improve.

The ability to implement such systems in production environments has been restricted due to limitations of conventional ultrasonic technology. The MMM solution is a breakthrough in this regard and allows us to greatly expand and create new applications.

Key benefits to the MMM ultrasonic technology are:

¡ï Can stimulate wideband (sonic to megahertz) acoustic activity throughout the extruder head or die greatly improves the process.
¡ï MMM eliminates standing waves, the areas of low and high acoustic energy, as seen in fixed frequency systems.
¡ï MMM technology will effectively drive most any size tool or mechanical systems.
¡ï Wave-guides connecting the transducer to the tool can be extended up to 3 meters for very high heat environments or unusual applications requiring the transducer to be located away from the working tool.

Ultrasonic Liquid Filtering and Inline Filter Cleaning

The ultrasonic technology offers new design flexibility and adaptability to most any size inline filtration system for micron or submicron materials dispersed in a liquid.

Ultrasonic Filtration Advantages:

¡ï Significant increase in flow rates.

¡îCleaner filter element
¡îUltrasonic acoustic effects are actively working to reduce surface tension, cohesive forces, and/or adhesive forces.

¡ï Allows in process self cleaning of the filter for continuous processing.
¡ï Greatly improves reverse flow filter cleaning and deblinding.

Example Applications:

¡ï Micron and submicron materials dispersed in liquids
¡ï Metal powder slurry
¡ï Ceramic slurry
¡ï Biotech and Pharmaceutical products
¡ï Water and wastewater processing

New Technology Offers Adaptability:

¡ï New transducer clamp-on technology allows easy adaptation to existing housing designs and retrofit possibilities.
¡ï For any filter type: Sintered Metal Filters, Membrane, Ceramic, etc.

 

New Multi-Frequency Ultrasonic Systems:

There now exits the industry¡¯s most advanced ultrasonic technology for liquid and liquid slurry filtering applications. The patented MMM (Modulated, Multimode, Multifrequency) ultrasonic generators can stimulate highly efficient wideband (sonic to megahertz) acoustic energy to most any liquid filled filter chamber. Compared to conventional fixed/frequency solutions The wideband ultrasonic techniques improve filter throughput, improve inline cleaning continuously, and improve reverse flow back flush.

Key benefits to the new technology are:

¡ï Wideband (sonic to megahertz) acoustic energy provides greater acoustic stimulation to improve process flow rates.

¡ï MMM eliminates the standing waves seen in fixed frequency systems.

¡î Eliminates blinding in low amplitude nodal points
¡îEliminates damage to filters in high amplitude nodal points.

¡ï Fully programmable power and modulation technology
¡î Power adjust 1% to 100% (standard power modules in 300 watts, 600 watts, 1200 watts, and up to 20 kW on request)
¡î Pulse Width Modulation Period (Period 10 ms to 1,000 ms)
¡î Pulse Width Modulation Ratio (0% to 100%)
¡î MMM special modulation settings (fast sweeping, sweeping, & tracking)

¡ï Transducer from 20 kHz to 45 kHz and higher frequencies on special order.

¡ï MMM technology will drive most any size and shape filter housing.

¡ïMMM driven converters may be connected to most any efficient point on a cylindrical stainless steel filter housing.

¡ïA field adjustable resonant frequency option allows filter housings to be built without specific ultrasonic resonance tuning. This means filter housing designs can be simplified and produced at lower cost.

Example: Transducer mounted directly to filter housing end. (Sintered metal filter)
Example: Clamp mount Transducer systems allows easy adaptation to existing housings
¡ïMMM Frequency Agility:
The same DSP technology that allows the MMM generator to be adaptable to any size or shape filter housing is used to provide unprecedented frequency agility. Other fixed-frequency systems are driving the total acoustic system (converter, filter housing, & liquid) at a frequency optimized for the converter without full consideration of how the filter housing and contents are changing the whole system resonant frequency. Rather than fighting physics The systems may be adapted to the new resonant frequency when an un-tuned mass is attached to a converter. Normal MMM factory options allow for system resonant frequency adjustment within a 12 kHz window (e.g. 25 kHz to 37 kHz). Such agility allows fine tuning for optimum performance.

Ultrasonic Sonicator / Homogenization

In combination with The fixed frequency generators we offer a wide range of acoustic elements to meet all of yThe high power Sonicator / Homogenization needs. Using advanced digital generator technology we have set a new standard in high power liquid processing.

The new generator design offers new capabilities in tracking shifts in the center operating frequency. Normal generators are unable to manage even minor shifts (30 Hz to 100 Hz) when probes become de-tuned due to cavitation wear. The systems can track simple probes over a very large frequency range of ¡À 500 Hz, a 1,000 Hz window in some cases. That means extended probe life, more reliable operation, and less maintenance.

The converters feature a sealed front mass interface with upper air cooling ports for continuous operations. Boosters are available in titanium or aluminum, with or without mounting rings. Probes may be constructed to The specifications. Standard probes are made of high grade titanium in diameters up to 60 mm.

Applications include:

¡ï Sonoreactors
¡ï Homogenization
¡ï Emulsification
¡ï Dispersion of solids in liquid
¡ï Disruption of bacterial cells, viruses and spores
¡ï Acceleration of chemical and enzymatic reactions
¡ï Liquids degassing
¡ï Liquid Processing in static or flow cell chambers.
¡ï Laboratory or industrial applications.
