The innovative HDS E 3.3/25-4 M Ec is an electrically-heated hot water pressure washer that boasts outstanding energy efficiency and a particularly high work temperature. With an innovative and highly effective boiler insulation made from a special foam, power consumption is drastically reduced in continuous standby mode. This allows energy savings of up to 40%. An eco!efficiency mode automatically switches the machine into the particularly efficient 60°C mode, saving valuable resources. The high work temperature (up to 85°C) is especially advantageous on greasy and oily stains, where a temperature of up to 70°C can be maintained in continuous operation thanks to servo control.
