One of the most advanced gentle but effective swirling abrasive systems available, remotely controlled by operator. Removes brittle soilings and coatings such as carbon sulphation, lime encrustation and limewash.
VorTech is a 'swirl-abrasive' system, born out of the "Jos" (pron. "Yoss") technology, originally developed in Germany, in the 1980s. The system uses a selected abrasive carried by a flow of compressed air to a nozzle, at which point water is added. The mixture then passes through the nozzle and exits in a vortex, which is directed at the substrate to be cleaned.
