DOFF CLEANING SYSTEM
The DOFF system is unique in achieving temperatures of up to 150 degrees at the nozzle end making it a superheated water system which, unlike high pressure washers, does not cause harm or shock to fragile substrates.
The steam/superheated water will remove paint, moss, algae, fungi and other biological matter and will also kill off spores.
There's then no need to use a chemical biocide during the removal process or as a protection against further biological activity.
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 (approximately 80% less water). The surface is therefore not saturated and will be dry within minutes avoiding damage to the building fabric as a result of trapped moisture.
It is a useful sterilisation tool for kitchens, toilets, swimming pools, hospitals and factories. There are no harmful chemicals being used.
DOFF is ideally suited for use on brick, stone, concrete, tiles, wood, faience and terracotta.
