Established in 1998, Primasonics® International Ltd is the worldwide leader in design, manufacture and supply of Acoustic Cleaning Systems and Technologies. Based in Penrith, Cumbria, and augmented by a network of agents spanning the globe, our products are used in a variety of industries such as Power Generation, Cement, Petro Chemical, Food, Gypsum, Carbon Black, Chemical, and many more.
We design, manufacture and sell Acoustic Cleaners and Sonic Soot Blowers for the prevention of particulate build up and blockage in a wide range of industrial applications. We also sell a Prima Whip for the safe, efficient and remote cleaning of already blocked silos.
We are one of the few companies in the world that actually specialise in Acoustic Cleaning technology and offer the widest range of frequency models which can be tailor made to fit most installations and environments.
Acoustic Cleaning encompasses the realm of sound transmission through solids. It is best described by the creation of rapid pressure fluctuations. These pressure fluctuations are transmitted into the particulate matter or “bonded” dry material causing the solid particles to resonate and dislodge from the surface they are deposited on or bonded to. Once dislodged, the materials fall, either due to gravity or are carried away by the gas or air stream within the process.
The powerful sound waves are produced when the short bursts of standard plant compressed air enters the wave generator and force the only moving part, an aerospace grade titanium diaphragm, to flex creating the powerful “base” sound wave. This “base” tone is then transmitted by a range of different bell sections, depending on the application, into selected fundamental frequencies between 60 – 420Hz in our Audiosonic™ Acoustic Cleaner Range.
This non-intrusive, affordable technology can be used to aid, and often replace, more damaging cleaning methods such as Steam Soot Blowers, Air Cannons, Mechanical Rapping Systems and Vibrators. They can increase the efficiency of process plant, provide improved thermal conductivity, prevent material blockage and remove particulate build up wherever ash, dust, powders or granular materials are processed, generated, stored or transported.
