Kärcher HDS Hot Water Pressure Washers: HDS 7/10 to HDS 18/18
Cutting through oil, grease and heavy soiling on vehicles, plant, workshops and production areas, where hot water cleans faster than cold and needs less detergent. Kärcher HDS and HDS-E, 700 to 1,730 l/h.

Kärcher
The HDS at a glance
A Kärcher HDS heats the water it sprays, so oil and grease break down faster and less detergent is needed. Most fire an oil burner on mains power; the HDS-E heats electrically, and the engine-driven versions need no power connection.

New to order
New Kärcher HDS built to order
New specifications ordered from the factory, built to the capacity, mast and options you choose. New machinery lead times are as low as 2-3 weeks.
Electric and engine-driven
The HDS-E 8/16-4 M gives 760 l/h at 160 bar and up to 85 °C with no burner, for food plants, hospitals, kitchens and other indoor areas. It comes with 12, 24 or 36 kW of heating, and the higher ratings hold more heat in continuous work.
Away from mains power, the HDS 8/20 De (diesel) and HDS 8/20 G (petrol) deliver 800 l/h at 200 bar. The HDS 1000 De (diesel, 200 bar) and HDS 1000 Be (petrol, 210 bar) give 900 l/h, and all four sit in a steel frame built for crane lifting.
