DOFF machines water supply is fed via a pump into a hot-box where it is rapidly heated to temperatures of up to 150 degrees.
This superheated water is then fed through high-temperature heat-resistant hoses to the nozzle at a rate of between 3-5 litres per minute to provide exceptional cleaning capability and is commonly used to remove:
● Paint coatings (most oil and plastic types)
● Graffiti
● Algae, moss, and fungi
● Wax coatings
● Chewing gum
● Bitumen, oil, grease, and much more
The surface being cleaned does not suffer any damaging pressure, thermal shock, or deep saturation. The surface dries within minutes, with no long-term damage from trapped moisture.
DOFF is widely used in building conservation and restoration, industry, food production, hygiene control, hospitals, factories, transport & vehicle depots and workshops, etc. There’s no need to use a chemical biocide during the removal process or as a protection against further biological activity after using the DOFF.
