NEC Acoustic Horns are unique cost effective, low maintenance, innovative effective solution that operates better than any other traditional methods of preventing particulate build up and aid material flow within a wide range of industries. NEC Acoustic horns prevents particulate build up and aids material flow within a wide range of industries and process applications wherever ash, dust, powders or granules are processed, generated, stored or transported. Acoustic Cleaners provide a powerful and effective solution to Boilers, Electrostatic Precipitators, Super-Heaters, Economizers, Air Heaters, Ductwork, Filters, ID Fans, Spray Dryers, Horizontal & Rotary Drum Vacuum Dryers, Mixers and Blenders, Dry Material Bulk Vehicles, Ship Cargo Holds, Air Classifiers, Silos and Hoppers, etc. Operational Features Acoustic horns consists of wave generator and amplifier, which are made from 316-grade stainless steel as standard. Acoustic horns are designed to produce acoustic energy and amplify low frequency sound at high intensity for effective removal of unwanted particulate build up and aid material flow. Acoustic horn produces extremely high-pressure acoustic energy, level with a fixed frequency band. The powerful sound waves are produced when the short bursts of standard plant compressed air enter the wave generator and force the only moving part, titanium or high grade material diaphragm to flex creating the powerful “base” sound wave. This “base” tone is then transmitted by a range of different bell sections into selected fundamental frequencies between 75- Specification
