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.
The steam/superheated water will remove paint, moss, algae, fungi and other biological matter and will also kill off spores. This means there’s then no need to use a chemical biocide during the removal process or as a protection against further biological activity.
We recommend the DOFF for use on surfaces such as brick, stone, concrete, tiled (glazed and encaustic), wood, faience and terracotta.
The DOFF is also a useful sterilisation tool for kitchens, toilets, swimming pools, hospitals and factories.
Water Dispersed Per Minute
As the Doff uses super-heated steam, there are no harmful chemicals being used.
After being used outdoors, the debris needs to be separated from the water and disposed of in accordance to local regulations. The water, however, will simply run into the ground to be absorbed back into the earth.
The DOFF Recovery System or DRS is a specialist ancillary to the DOFF system for internal cleaning works or for use in areas where water recovery is an issue.
It has a hooded lance which extracts all steam, water and debris in to a specially developed vacuum unit via a heavy duty, high temperature hoses.
Water is pumped out of the unit automatically and debris is collected in a catch tank.
With the Telescopic DOFF Pole, reaching inaccessible areas becomes a lot easier.
Maintaining complete water pressure over a long distance allows you to give those tricky areas as deep of a clean as any other.
