Over 35 years of acoustic cleaning for various industries 

The advantages of the NIRAFON® system:


NIRAFON doesn’t cause any harm to structures. It causes no mechanical wear, no corrosion, or erosion. Acoustic cleaners require little space, and the maintenance and operating costs are low.


NIRAFON is cleaning during the process. It also cleans the shadow areas and around the corners. Acoustic cleaning drastically reduces the use of water at the plant.


The NIRAFON refund time of the system is short. A tailor-made plan is always drawn up by NIRAFON Oy according to the buyer’s needs and application.


Heat transfer and other surfaces to be cleaned stay permanently clean and the process can continue without interruptions, rendering expensive shut-downs unnecessary.
