DOFF is a steam based stone cleaning system. It’s unlike any other steam system and can achieve temperatures of up to 150°C at the nozzle end. The operator is able to vary the temperature and pressure to remove many different types of paint and biological matter.
THE DOFF SYSTEM EFFECTIVELY REMOVES
- Paint coatings
- Certain types of graffiti
- Bird or vermin fouling
- Algae, moss, fungi
- Other biological matter
- Wax coatings
The TORC system creates a gentle swirling vortex using a mixture of low air pressure, little water and a safe inert fine granulate.
The Torc Head is modularised into separate components which results in an efficient and gentle swirling vortex using even less water and granulate than the original Jos system.
The removable nozzle cone can easily be changed so that a larger cone can be used to clean large areas such as ashlar or a smaller nozzle cone can be used for more intricate detail such as an elaborate capital or rustications.
THE TORC SYSTEM EFFECTIVELY REMOVES
- Carbon sulphating
- Lime & cement-based paints
- Paint residues
- Some old oil based paints
- Bitumen
- Lime scale
