During the shutdown maintenance ultrasonic cleaner can be used for the cleaning of large process components, one of the most common being the one used for heat exchanger fouling cleaning. HX Power Cleaning has developed a transportable autonomous ultrasonic cleaning vessel, a container cleaning machine which can be temporarily located at the customer’s site during the maintenance shutdown.  This container equipped with ultrasonic tank is prepared for outside use thanks to its autonomous power generation and weather resistant construction. Thanks to these features, shell and tube heat exchanger fouling can also be removed from the largest parts during the refinery maintenance shutdown.Compared with the traditional hydroblasting method used for heat exchanger maintenance, ultrasonic heat exchanger cleaning provides considerable water, labor, and energy savings.

For example, conventional hydro-jetting can use over 20,000 liters of water per one heat exchanger unit. Furthermore, all the used water needs water treatment. In the case of the ultrasonic cleaning process the water is contained in a tank and changed only after the cleaning of several bundles.  This means that the tank cleaning equipment is providing huge savings in the long term.  The ultrasonic cleaning method cannot damage the surface as is the case with high-pressure jetting and reduces the safety concern of operators compared with the high-pressure cleaning method.
