NACS® Operation Principle

Nirafon Acoustic Cleaning Systems utilise the energy in the low frequency sound waves (60-250Hz) generated by a pneumatically operated Acoustic Horn. This energy resonates and dislodges dust, soot or other particulate matter which tends to deposit on various surfaces of industrial equipment. The ability of sound waves to move in three dimensional space, even into nooks and crannies, makes it possible for Acoustic Cleaners to reach and clean all inaccessible places and even surfaces that are hidden around corners, which otherwise cannot be cleaned using conventional methods.

Nirafon Acoustic Cleaning Systems generate sound pressure levels of more  than 150dB by pneumatic activation of a specially designed Diaphragm housed inside the Generator of the Acoustic Horn.These pressure peaks are generated in controlled bands of frequencies found to be most effective in breaking bonds between the particles of the deposits and the equipment surfaces as well as between the particles themselves, leading to their dislodgement.

Our present range of Acoustic Cleaning Systems can work effectively up to application temperatures of 1000°C for which suitable material of construction (Cast Steel/Stainless Steel) is selected.

Nirafon Acoustic Cleaning Systems (NACS) come with a high degree of operational flexibility suited to the requirements of the applications.

The sounding cycle parameters can be set individually to optimize the cleaning effect.
