Efficient boiler cleaning with

Shock Pulse Generators

Cleaning method

With our proven online cleaning technology, deposits on heat exchanger surfaces, e.g. membrane walls and tube bundles, can be successfully prevented in large boiler plants. In retrofit projects, the deposits can be  significantly reduced. This innovative Shock Pulse Technology enables you to achieve longer operating periods, higher boiler availability and a reduction in maintenance and operating costs!

More than 1000 installed Shock Pulse Generators (SPG) are keeping critical boiler areas permanently clean, for multiple fuels like municipal solid waste, industrial waste and coal, as well as in process plants. Waste, industrial, coal-fired power plants and process plants permanently clean!


Our product series, the Shock Pulse Generator SPGr, revolutionizes automated industrial boiler cleaning. The innovative further development of our existing technology enables even higher cleaning performance with reduced maintenance and space requirements. This effectively meets customer requirements for high plant efficiency and sustainability.
