Infrasound cleaning
Improve the Efficiency, Lifetime and Availability of you asset
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
Stenvalls Trä, Piteå, Sweden
Stenvalls Trä in Lövholmen, is a sawmill in Piteå, Sweden. The boiler and the economiser are used to heat water for the drying process and fulfil other heat needs. The boiler is in operation for the whole year and must be stopped up to 3 times for manual cleaning. Each stop for manual cleaning results in a 48hr production loss and required compensation firing with oil.
Sandviksverket, Växjö, Sweden
A case study and report from our Infrasound cleaning installation at Sandviksverket, Växjö, Sweden. The installation of the Infrasound Cleaner leads to a 50% reduction of steam sootblowing in the economiser and air preheater, and full elimination of sootblowing in the catalyst.
Södra Wood, Långasjö, Sweden
A case study and report from our Infrasound cleaning installation at Södra Wood, Långasjö, Sweden. The goal with the Infrasound Cleaner projects at Södra Wood was to reduce the need for manual cleaning and auxiliary firing due to the reduced number of stops.
Iisveden Metsä OY, Iisvesi, Finland
The purpose of the project is to maintain cleanliness of the vertical smoke tube passes on a biomass-fired boiler. That way, differential pressure will remain stable and operational and maintenance costs will be kept low.
