There is a situation when industrial enterprises are forced to spend huge amounts of money to fight with hard deposits (scale) occurring in cooling systems and thermal-power devices on the surface of heating or cooling. The resulting scale reduces the heat transfer, a reduction in the cross-section of the pipes, or a decrease in the period of exploitation and productivity of the equipment used. A new method of non-reagent treatment, based on the combination of acoustic and rotating magnetic fields in the working zone, is proposed. The new method will be called acousto-magnetic. By means of acousto-magnetic treatment, it is possible to slow the formation of inorganic deposits significantly, to reduce the rate of internal corrosion, to remove the film of fungi and bacteria from the inner surface of pipelines, without interruptions in the system, without interference in the operation of the system, without reagents and harm to the environment. One of the main factors affecting the efficiency of the device is the form of a pulsed supply voltage. The results of the investigation of the influence of the impulse voltage on the change of the voltage gradient of the magnetic field in the working zone of the acoustic and magnetic device (AMD) model are presented in the article. To conduct the research, a hypothesis is advanced about the possibility of increasing the efficiency of the acoustic and magnetic field of the device by means of various forms of impulse voltage. For the experimental study of the hypothesis, an AMD model was developed, using the ELCUT 6.1 software complex. In the process of modelling, a geometric model was created, then the physical properties of the model blocks were set, and spectral analysis of the signals was conducted using the MATLAB software application package. The obtained results show the possibility of increasing the efficiency of AMD based on the pulse voltage of different forms.
