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
SCG Banpong, Thailand
The purpose of installing Infrasound Cleaning from Heat Management was to reduce, or preferably eliminate, the existing shot cleaning system, prolonging the tube life while maintaining cleaning efficiency.
Setra Heby Sawmill
The Customer has a 16MWth biomass furnace with a hot water smoke tube boiler and subsequent economizer in Heby, Sweden. Their focus is mainly on delivery to all lumber dryers, and the facilities on the sawmill area. The Customer had a different automatic cleaning system installed, which they were not satisfied with.
Moelven Bioenergi, Norway
At Moelven Langmoen, a smoke tube boiler is fuelled using byproducts from production to generate extra electricity. The preexisting air soot-blowing system could not preventatively clean the tube bundles, which caused unstable flue gas temperature and required regular maintenance and additional stops for manual cleaning.
Kraftvärmeverket Eskilstuna, Eskilstuna Sweden
Before the installation, the primary superheater had large deposits that built up between the tubes. In the duct after the economizer, there was a 200 mm thick layer of dust.
