We first started using ultrasonics to clean heat exchangers that were impossible to clean with normal methods and exchangers that had difficult to reach areas.



The combination of chemical, heat, agitation and ultrasonic power in the right combination was very successful in removing industrial scale, calcium build up, varnishes, corrosion and other build up on tubes, in crevices, blind bolt holes and other cavities.


The results were excellent, exchangers were de-scaled with no damage to the parts. We were soon approached by our clients to de-scale other equipment such as valves, manifolds, housings , pipe-work, condensers, and other parts so changed the process to a multi-stage/ multi tank process of cleaning passivation and drying.



The process works by converting electrical energy through transducers into high frequency sound waves, ultrasonic energy. In effect tiny bubbles form and then implode on the part which lifts the contamination when used in combination with the mix of chemical, heat and agitation. That combination process is now documented in procedures that include the passivation and drying of the part.



Other advantages of the ultrasonic cleaning process over the more traditional methods are reduced labour costs (cheaper prices for our clients) and reduced detrimental effect on the environment in comparison to high water consumption steam cleaning and the problems associated contaminated water.


When pressure testing is required such as with heat exchangers the procedure includes a NATA endorsed test procedure to AS 17025. Responding to our customers requirements, we have a specific process for the cleaning of Heat Exchangers, Industrial Radiators and Valves.
