Improving forest industry productivity with NIRAFON® Acoustic Cleaners


Main advantages of the NIRAFON® in the forest industry

In the forest industry, as well as in the power and energy sector, acoustic cleaners offer significant benefits. NIRAFON® applications boost overall productivity, enhance heat transfer efficiency, and reduce the need for manual cleaning. 

NIRAFON® systems cut down on plant downtime, eliminate the requirement to shut down dust collectors, and minimize damage risks during cleaning. Acoustic horns, especially effective at cleaning dry, loose, powder-like deposits, prove their versatility across various industries.
