The DOFF system heats water to temperatures of up to 150°C, allowing effective removal of grime, paint residues, algae, moss, lichen and biological growth without abrasion.
Crucially, the temperature and water flow are fully adjustable, allowing the system to be precisely controlled to suit the surface, its condition and the level of contamination. This ensures delicate materials are cleaned safely, while heavier soiling can be treated effectively without risk of damage.
