Ultrasonic cleaners use high-frequency sound waves to shift grease, scale and other contamination from parts quickly and thoroughly. If you are purchasing an ultrasonic cleaner for use in your workshop, there are a few things you should consider before making your purchase to ensure that you choose the right cleaner for your needs.
Tank Capacity and Dimensions
The size of the tank is the first aspect to consider, smaller units for the workshop are available in 3-10 litres, but a Large Ultrasonic Cleaner starts at 20 litres and can be as large as 200-500 litres. To select the correct size, you must first measure the largest part you are going to clean and include clearance on all sides, this must then be compared to the internal dimensions of the tank, not the number of litres it holds.
Ultrasonic Frequency
The most common frequency for general parts cleaning is 40 kHz. This frequency will produce the strongest cavitation and is ideal for removing grease and carbon deposits from components. Higher frequencies, around 80 kHz to 130 kHz are used for cleaning more delicate items such as optical components or fine jewellery. These frequencies produce finer bubbles which are less likely to cause surface damage.
Heating Capability
Most large Ultrasonic Cleaners come equipped with a built in heater. This allows you to heat up the cleaning solution to around 50-60 degrees Celsius, which is far better at removing grease and oil than cold cleaning solution. Check the wattage of the heater as well as the machine’s ability to hold temperature over long cleaning periods.
Basket and Racking Options
Most cleaners come with a standard basket, but some manufacturers offer additional racks, dividers, or even hanging fixtures. This is particularly important if you are cleaning large numbers of small items, such as nuts and bolts, as they can easily get damaged by being knocked against other parts in the cleaner.
Cleaning Fluid Compatibility
Selecting a suitable cleaning solution is just as important as selecting the correct ultrasonic cleaning equipment. Some cleaning jobs are better suited with the use of a water-based detergent, while others require the use of a more specialised solvent. Make sure to follow the safe handling of cleaning agents at work guidance and select the correct products for your cleaning job.
