Application: Due to the velocity or speed of sound [344 m/sec] of these cleaners the higher the frequency (the shorter the wavelength path) produced high intensity localised cleaning power [1 – 3 m] i.e. Models PAS-210/PAS-350. The lower the frequency (the longer the wavelength path) allows powerful long distance deep penetrating cleaning power [20 – 30 m] i.e. PAS-60/PAS75/PAS-100 to occur. PrimasonicsTM Audiosonic Acoustic Cleaners have successfully been employed in a wide range of applications
PrimasonicsTM Audiosonic Acoustic Cleaners have many distinct advantages over other conventional methods of ash removal namely steam sootblowers, waterjets and tumbling shot. Steam sootblowers are usually only employed once per 8 – 12 hour shift thus allowing the ash to build up and sinter. They attack only the leading edge of the tubes and cause corrosion and wear resulting in expensive and unscheduled repairs. Waterjets can cause severe thermal shocks to the tubes and vessels, again resulting in reduced lifespan of systems. Tumbling shot is costly, dirty and indeed can itself cause severe blockages within the economiser section tube bundles. Also within ESP mechanical rapping systems can be expensive to maintain and by their very nature can cause damage to the key ESP components.
PrimasonicsTM Audiosonic Acoustic Cleaners on the other hand are 'sounded' for a few seconds every few minutes, thus preventing a build up from occurring in the first place. Sound waves travel in all directions, enveloping every tube and reaching every structural surface. They cause absolutely no structural or vibrational damage and their continued employment is automatic and virtually maintenance free.
By continually preventing ash from building up on conductive surfaces, maximum thermal conductivity may be maintained. A further benefit is by continually removing small quantities of ash; it minimises the opportunity for opacity spiking to occur.

The benefits of employing PrimasonicsTM Audiosonic Acoustic Cleaners within the plant are
Safety - Minimise the risks involved in personnel entering confined plant areas to manually clean and carry out repairs.
Environment - Reduces the occurrence of opacity spiking and resulting environmental pollution
Output - By preventing material build up, thermal conductivity is maximised and fuel usage reduced
Reliability - By preventing material build up and replacing harsh cleaning methods, the operational life of the various plant sectors is enhanced.
