Ultrasonic anti-scaling
Using this method reduces the consumption of chemicals and, while reducing costs, increases the life time of the tube. This method as a preventive method for sedimentation is very effective in preventing the formation of deposit and minimizes the number of frequent shutdown in production lines for descaling purpose.

Mechanisms of work:
Firstly, when water is sound up by ultrasound of sufficient intensity, crystals of hardness salts formed in heated water are destroyed or split.
Secondly, ultrasound excites high-frequency vibrations in metal heat exchange surface. Spreading by the surface, ultrasonic vibrations prevent formation of scale deposits on it, slowing down precipitation of salt crystals formed. Due to different mechanical rigidity of metal and scale deposit layer, flexural vibrations of the heat exchange surface destroy the scale layer formed. But, if a scale layer has already been formed on the heat exchange surface, ultrasound destroys it.
