The innovative electrically heated hot water high-pressure cleaner HDS E 8 / 16-4M impresses with outstanding energy efficiency and a particularly high working temperature. Thanks to the innovative high-insulation boiler insulation made of special foam, the power consumption of the unit is reduced drastically in continuous stand-by operation. This allows up to 40% energy savings. The eco! Effiency mode automatically switches the device into a particularly efficient 60 ° C operation, thus saving valuable resources. The particularly hot working temperature of maximum 85 ° C is particularly advantageous for grease and oil-containing contaminants, whereby servo control can keep up to 80 ° C in continuous operation. The pre-heating time is significantly reduced by means of a rapid heating chamber. The hot-water high-pressure cleaner is used wherever exhaust gases are disturbed or even prohibited, eg in foodstuffs, hospitals, large kitchens or industrial kitchens.
