The ultrasonic cleaner has proven to be one of the – if not the – best methods for cleaning in an array of industries, although it has historically been used mostly in the automotive sector as well as the aeronautics sector. With ultrasonic cleaning, you can benefit from gentle and precise cleaning which does away with all sorts of contaminants and pollutants, and it’s a process that’s quick and truly effective. But there are different ultrasonic cleaners out there, each with different capabilities, and you can even have an ultrasonic cleaner made according to your exact specifications. So what does it take to choose the best ultrasonic cleaner for your needs? It is an investment, so you need to choose wisely. Here’s how you can decide on your ultrasonic cleaner for your business.
1. The power and frequency of the ultrasonic cleaner
Most of the ultrasonic cleaners available today will operate between 28 kHz and 120 kHz, and a lower-frequency ultrasonic cleaner will create larger bubbles in the cavitation process, which results in cleaning that is rougher and more abrasive. The larger frequency is recommended by experts and providers of ultrasonic cleaning services for coarse and rough cleaning, such as the removal of compounds from a metal surface that’s sturdy and solid. If you are planning to clean delicate objects and parts, however (which include soft metals with a polished or finished surface and jewellery), an ultrasonic cleaner with a higher frequency is ideal.
Bear in mind, though, that the most common frequencies for ultrasonic cleaners are from 38 kHz to 40 kHz, as they are often suitable for the majority of industrial and commercial cleaning objectives and applications. The power your ultrasonic cleaner generates should be able to deal with your most difficult applications. The controls on the generator should also allow you to reduce the power when necessary, particularly for more delicate applications.
2. The wave sweep and generator adjustability
You can also utilise an ultrasonic cleaner with wave sweep capability, and this capability is highly recommended and ideal for almost all applications and cleaning processes. In fact, with a wave sweep, you can make use of different frequencies (which also come with varying wavelengths), so you can eliminate any inactive or even ‘dead’ zones within the cleaner’s cleaning tanks. With the wave sweep, you can benefit from a more uniform, effective clean, even if you have parts which are more intricate and detailed.
3. The right-sized racks and baskets
One important note to remember as well is that you should choose the right-sized racks and baskets. The items you are planning to clean in your ultrasonic cleaner mustn’t touch any part of the ultrasonic transducer, which is found within the tank. This means, then, that your baskets and racks must be chosen specifically for your precise application. Any basket or part which makes contact with the transducer or touches the transducer may make scratches or etches on the surface, which can cause erosion over time and destroy the transducer pack’s overall integrity. Once the integrity is destroyed, the transducer pack cannot be repaired and will, instead, have to be replaced.
