Time, heat, detergent and ultrasound combine in cleaning of industrial surfaces

The cavitation caused by ultrasonic waves with a frequency of 28kHz has a cleaning power comparable with micro-brushing. The advantage of this cleaning method is its efficiency and the capacity to clean without damaging pieces. Gone are the days of procedures that are much more aggressive with the materials to be treated, with the evident consequences of the wear to them.

Thanks to ultrasound with a frequency of 28kHz it is possible to reduce the use of detergents by up to six times in relation to other cleaning methods, with a clear advantage in terms of economic savings and greater safety in the workplace. The prevention of occupational risks is much easier to implement in the company through a system of these characteristics. Once the cleaning cycle has been started up, the machine does not require the intervention of the operator.

Time, heat, detergent and cavitation are the factors that come into play in the cleaning process. They can be combined in different ways depending on the debris to remove, the surface to clean and the aims of the cleaning process. If one of the factors is reduced, it needs to be compensated by one or more of the other factors in order to obtain a satisfactory end result.

Our frequency of 28kHz makes it possible to generate cavitation that releases more energy than 38-40 kHz for example. This is why Ultratecno can reduce the times of the cleaning cycle and the amount of detergent used. The balance between the power of the ultrasonic waves, time, water temperature and detergent is what makes a cleaning process work. Also, Ultratecno can add another factor, which is the movement of the lift, which helps and speeds up the cleaning of the piece.


Selecting the right detergent for a specific material (steel, aluminium, copper, plastic, etc.) and to get rid of a specific type of polluting particles is a key factor in the cleaning process. The time for the cycle depends on the surface to be cleaned and the dirt to be removed.

Even reaches the most difficult spots

This cleaning system makes it possible to access small orifices, that was undoubtedly very difficult with traditional cleaning procedures. The benefit of using ultrasonic waves in a water tank is that the energy released has an effect anywhere where the water can penetrate. And the power generated by the ultrasound of a lower frequency like 28kHz helps to obtain greater cleaning power, while always respecting the material.
