Our machines

Our mobile cleaning machines have been developed in the Netherlands under our own management and have a European patent. In addition, they have the CE quality mark and a Kiwa BRL-K14032 certification. The machines allow for the safe, efficient and rapid cleaning of drinking water systems. As a result of a singular combination of cold and hot water, air and environmentally-friendly chemicals, both Legionella pneumophila bacteria and biofilm are removed from drinking water pipes (see animation).
