Industrial ultrasonic cleaning machines are an effective solution for many cleaning applications. They usually work faster and clean more thoroughly than traditional cleaning methods. The use of harsh chemicals and hand scrubbing can be avoided when the proper ultrasonic cleaning machine is configured. The key is to choose a cleanser with the right features and functions. Important factors to consider when choosing an industrial ultrasonic cleaning machine include frequency, container size, power, cleaning fluid, and operating temperature.

1. Choose the best ultrasonic cleaning frequency

The ultrasonic frequency determines the energy level of the cavitation bubbles that produce a cleaning effect in the cleaning fluid. Low frequencies result in larger, more energetic bubbles that are more powerful for cleaning, while high frequencies produce smaller, lower energy bubbles. Low frequencies between 25kHz and 40kHz are suitable for cleaning hard surfaces or removing oil, but these frequencies can cause pitting if the part surface is soft. The ideal frequency is based on the material of the object being cleaned, the surface size, and the nature of the contamination.

2. Size of ultrasonic cleaning tank

The container size of the cleaning system is critical because the parts to be cleaned must be immersed in the cleaning fluid. For single-use ultrasonic cleaners, custom vessel sizes suitable for cleaning specific components are appropriate. For general-purpose cleaners, the jar must fit the largest part of the longest size.

A basket may be required if many different parts are to be washed at the same time. The basket keeps the widgets clear at the bottom or side of the tank, because vibration on the tank walls during cleaning can damage the components. If a basket is large enough, the sink must be large enough to hold the basket.

3. Ultrasonic clean power

The ultrasonic cleaning system must produce enough ultrasonic waves to fill the cleaning tank. If the power is too low, will produce dead spots, uneven cleaning. The turn-key system automatically provides the correct power level for the ultrasonic cleaning system, but if the ultrasonic generator, sensor and cleaning tank are purchased separately, it is important to ensure that the power is large enough to be effective for cleaning.

For large tanks, several sensors may be required. Suppliers of industrial ultrasonic cleaning machines can analyze the requirements and recommend appropriate power levels to customers. Both the ultrasonic power rating and the configuration of multiple sensors will affect cleaning performance, especially if the ultrasonic cleaner is added to an existing tank.

4. Clean with mild soap and detergent

Industrial ultrasonic cleaners can be used for light cleaning with deionized water, but some heavier cleaning applications can benefit from the use of soaps, detergents or mild solvents. If a particular contaminant is difficult to clean, a particular solvent contaminant tends to speed up cleaning and improve cleaning performance. Mild soaps and detergents can help clean oily residues, but harsh chemicals are usually not used.

5. Use Heat to improve cleaning effect

Industrial ultrasonic cleaning machines can remove heavy pollutants made up of hardened grease and carbon deposits, but the cleaning process may take more time. These types of deposits can be softened by heating, and the soft material is easier to remove. Heating the cleaning solution just below the boiling point speeds up the cleaning of these applications and helps ensure complete decontamination.

To use heat, tanks and ultrasonic sensors must be able to operate at temperatures below 100 degrees Celsius. The fuel tank must be fitted with a heater and the parts themselves must be able to withstand high temperatures.
