The TORC system is a complete surface cleaning system that creates a gentle swirling vortex using a mixture of low air pressure, little water and a safe inert fine granulate. This vortex is then directed onto the surface to be cleaned and is safe, gentle and very controllable, remaining effective even on delicate or friable surfaces of stone, brick, terracotta, ceramic tiles, concrete and even glass.
The system can be used for the safe removal of pollutants such as carbon sulphation, lime, most paints, graffiti, fungi, bitumen and lime scale. It is also suitable for the cleaning of oxidation and sulphation from bronze, brass, copper and aluminium surfaces.
A changeable nozzle allows for the creation of a different size vortex cone, so a cleaning methodology can be specifically designed for each specific surface within each project. A larger vortex cone will allow for larger areas of ashlar façade to be cleaned more quickly, while a smaller vortex cone is suited to cleaning more intricate, uneven or detailed surfaces. This process can also be used in conjunction with environmental barrier products that can make the cleaning easier and more cost effective.
