What a Multi Ultrasonic Frequency Generator Does and the Benefits It Offers

October 27, 2016

What a Multi Ultrasonic Frequency Generator Does and the Benefits It OffersManufacturing companies often have a variety of cleaning needs for a wide range of items. They may have to clean parts and components during or at the end of the manufacturing process or they may have to regularly clean tools. Incoming parts may have to be cleaned before use or containers before and after being filled. Using traditional cleaning methods, many cleaning systems, chemicals and scrubbers might have to be stored and used.

With ultrasonic cleaning, most of these cleaning applications can be carried out with one ultrasonic system. Even if the applications require different cleaning intensities and the removal of different contaminants, a multi-frequency ultrasonic generator may be an effective and cost saving solution.

Multi-Frequency Ultrasonic Generators

Ultrasonic cleaning systems rely on sound waves that create bubbles in the cleaning solution. The ultrasonic sound waves are produced by an ultrasonic frequency generator linked to transducers submerged in the cleaning liquid. Different frequencies and powers deliver varying cleaning intensities. The higher the frequency, the gentler the cleaning action while higher power delivers more bubbles and greater cleaning power. For varied cleaning applications a generator that can produce different frequencies and deliver different power levels can represent an ideal cleaning solution.

Such a multi-frequency ultrasonic generator should be able to produce low frequencies around 30 kHz for intensive cleaning of robust parts at high power levels as well as frequencies over 100 kHz for more gentle cleaning of delicate parts. Transducer arrays must be able to handle the complete range of frequencies without major refit or set-up work. Such systems are flexible enough to handle various cleaning applications using the same equipment and cleaning set-up.

The Kaijo Quava Multi Ultrasonic Generator

Kaijo Corporation has developed a complete range of ultrasonic frequency generators covering almost all cleaning applications. The company offers both turnkey systems and individual components ranging in frequency from 19.5 kHz to 950 kHz. For cleaning applications that require multiple frequencies due to a variety of parts that have to be cleaned, Kaijo can supply the Quava Multi generator in two versions.

Each version can generate three frequencies, with the lower range model producing 26/78/130 kHz and the higher range model producing 38/100/160 kHz. The models have an eight-step power output with a maximum of 600 W and both models work with an array of transducers that can handle all three frequencies.

This means that the cleaning system can switch frequencies and adjust power output as required without having to change transducers or the ultrasonic generator set-up. Different types of parts and devices with different cleaning requirements and varying cleaning intensities can be cleaned by the same system. The Quava Multi generator is flexible enough for remote control operators to adjust the cleaning process as required.

The Quava Ultrasonic Frequency Generator Features

The Quava Multi generator is designed for multiple cleaning applications with easy changeover from one cleaning task to another. The generator has four selectable oscillation modes and automatic frequency tracking. It features Soft Start and Soft Stop functions that can be controlled via an RS 485 port and monitored with a 0 to 5 V output or a 4 to 20 ma signal. The power supply is 200 to 240 V single phase 50/60 Hz and the current at maximum power is 10 A. At installation or for the replacement of a transducer array or a generator, no field calibration is required.

Kaijo’s multi ultrasonic frequency generator is the ideal solution to varied cleaning requirements in a manufacturing environment with diverse cleaning needs. Kaijo has designed a cost-effective system that is built with high-quality components to deliver excellent reliability and performance.

The Benefits Industrial Ultrasonic Cleaners Offer over Traditional Industrial Cleaning Methods

October 19, 2016

The Benefits Industrial Ultrasonic Cleaners Offer over Traditional Industrial Cleaning MethodsMany manufacturing facilities have processes that require the cleaning of a wide variety of parts and devices. Traditional cleaning methods involve harsh chemicals and mechanical scrubbing, but environmental regulations make such processes less attractive. Parts that have complex shapes and crevices are hard to clean and traditional cleaning can be time-consuming.

The use of industrial ultrasonic cleaners as an alternative to traditional methods has become more widely accepted. Such cleaners are quick and effective with low operating costs. As companies become familiar with the technology and the benefits it provides, they often decide to try ultrasonic solutions for some of their more challenging cleaning applications and eventually switch over to the new technology for almost all their cleaning needs.

Ultrasonic Cleaning Systems

Industrial ultrasonic cleaning systems are made up of an ultrasonic generator, transducers and a container for holding the cleaning solution and the parts to be cleaned. The generator produces a high-frequency acoustic signal to power the transducers. The sound waves produced by the transducers in the cleaning solution create bubbles that provide the cleaning effect. Lower frequencies produce energetic bubbles with a robust cleaning action but they can damage the surface of delicate parts. Higher frequencies produce smaller bubbles with more gentle cleaning. It is important to choose the right frequency and system power for a particular cleaning application.

When the right industrial ultrasonic cleaner is used to replace a traditional system, parts and devices can often be cleaned more effectively. Ultrasonic systems can work in plain water or with mild solvents so the manufacturing facility can save the cost of chemicals and the cost of their disposal. If the company supports positive environmental policies, such a change is also desirable.

Ultrasonic systems work quickly so there may be savings in the time spent on cleaning. The systems are especially advantageous when traditional systems require mechanical scrubbing or when delicate parts are heavily contaminated and have to be cleaned. Working with different frequencies, system powers and cleaning solutions can satisfy most cleaning requirements.

Kaijo Ultrasonic Cleaning Systems

Ultrasonic cleaning system provider Kaijo Corporation is at the leading edge of advanced ultrasonic technology. Kaijo’s industrial ultrasonic cleaners emphasize ease of use and flexibility to meet the needs of a variety of cleaning applications. The system can deliver high power at frequencies between 19.5kHz and 1.6MHz.

Low frequency systems operating at up to 38 kHz can provide strong and robust cleaning for parts and devices such as glass, ceramics, lenses, medical devices and machined parts. The Kaijo Phenix III turnkey ultrasonic cleaning system can operate at 26 or 38 kHz and can deliver 600 or 1200 Watts of power. It comes complete with an ultrasonic generator and a stainless steel tank that has transducer crystals built in.

For higher cleaning frequencies Kaijo has a wide variety of systems and equipment for many different applications. The Phenix Legend ultrasonic generators handle frequencies up to 160 kHz and the Quava generators can operate at up to 950 kHz. These higher frequencies deliver gentler cleaning for more delicate parts. Components such as hard disk drives, LCDs, solar panels and aluminum parts often require more gentle cleaning while items such as electrical components, semiconductors, LEDs and some medical instruments are the most delicate and require the highest frequencies.

Kaijo can supply complete industrial ultrasonic cleaning systems or components to work with existing cleaning installations. While manufacturers may want to replace small traditional cleaning units with a turnkey ultrasonic system, it may be more cost-effective to add a generator and transducers to an existing cleaning tank for other systems. Kaijo can work with customers to help with their transition to ultrasonic cleaning and make sure they install the best combination of components, systems and frequency/power configurations to match their requirements. The result can be reduced costs and improved overall performance of the manufacturing facility.
