DOFF Integra Stone Cleaning Machine
What can DOFF be used for? The steam/superheated water will remove moss, algae, fungi and other biological matter and will also kill off spores. This means theres then no need to use a chemical biocide during the removal process or as a protection against further biological activity.
How does it work? DOFF cleans stonework and masonry using high temperature steam. Whilst the temperature in the system is high, the pressure on the surface being cleaned is very gentle and the volume of water is low. The surface is therefore not saturated and will be dry within minutes.
It is a high temperature steam-based cleaning system with nozzle temperature up to 150°C. Suitable for use in removing paint, biological matter and general dirt and grime without causing harm or thermal shock to the substrate. The DOFF system can be used in building restoration, industry, food production, hygiene control, hospitals, factories, transport and vehicle depots, and workshops.
