General info
Payback within 6-24 months after implementation
Our Infrafone cleaners (low-frequency acoustic cleaning) improves the profitability of boilers. This has been achieved thru more efficient soot cleaning in e.g. economizers, air-preheaters and catalysts (SCR’s), with a general payback time of about 6 to 24 months. Traditional soot cleaning technologies such as steam sootblowing, shot cleaning, sonic cleaning (high frequency), and manual cleaning are generally heavily reduced or eliminated in these applications.
Our range of products is the result of our unique knowledge and our customer focus. We calculate the optimal size and design of the acoustic cleaner for each customer’s particular need and the spatial possibilities of each installation.

Infrasound cleaning case studies
HEW Tiefstack, Hamburg Germany
Initially there were 4 layers in the catalysts at HEW Tiefstack. No soot cleaning equipment was installed from the beginning, since the boiler manufacturer Steinmüller was convinced, that by guiding the flue gas in parallel, the cat stones would not become dirty. The catalyst reactor was also built by Steinmüller.
Värtaverket, Stockholm Sweden
A case study and results from our infrasound cleaning installation at Värtaverket, Stockholm. The purpose of installing the infrasound generator on Värtaverket was to remove ashes stuck on the inner walls of the silo.
Idbäcksverket, Nyköping Sweden
A case study and results from our infrasound cleaning installation on a biomass boiler at Idbäcksverket. The reason for installing the Infrasound generators on Idbäcksverket was that the steam soot blowing causing extensive damages to the tube bundles, resulting in unplanned stops for repairs.
Suralaya Power Station, Suralaya Indonesia
There are two size 28 secondary Air Preheaters on Suralaya Power station (APH) and two size 22,5 primary APH on the 400 MW boiler. Infrasound cleaning is installed on one of the secondary APHs. All APHs are equipped with four steam soot blowers each, which were operated every 12 hours.
