Karcher HDS 5/11 UX Professional Hot Water Pressure Washer 110 Bar

The Karcher HDS 5/11 UX is a professional hot water pressure washer. It is compact and stands upright. It is built for light to medium duty jobs where time matters. The controls are simple. You pick OFF, COLD or HOT. It heats with a diesel burner and runs from a 230 to 240V mains supply.

Hot water melts grease that cold jets only smear. This washer heats to a maximum of 80°C. Operating pressure is 110 bar. Flow is 450 litres per hour. A 3-piston axial pump does the work. The motor is air-cooled and rated at 2.2 kW. Rated use is up to one hour a day.

It weighs 69.9kg but it moves well. Large wheels help on unpaved ground. The footprint is 620 x 620mm and height is 1160mm. That fits many car boots and small service vans. The pump and fuel tank are spill proof, so you can carry it lying down. The 6.5 litre tank uses 2.4kg of fuel oil per hour. A hose reel winds the 15 metre hose fast.

Protection is built in. A fine mesh filter guards the pump. A full ceramic valve gives a lifetime Karcher puts at five times longer. The auto shutdown stops the motor when you release the trigger. A detergent suction hose is fitted. It suits mobile valeters and maintenance crews.

A hot water washer heats the water as it passes through a burner coil. Heat softens grease and oil. Then 110 bar of pressure lifts it off. Flow is 450 litres per hour from a 3-piston axial pump. In real use that means cleaner vehicle parts and workshop floors in less time. The full ceramic valve cuts wear. Auto shutdown stops the motor and saves fuel when you release the trigger.

Hot water at up to 80°C can scald. Keep hands and feet clear of the jet. Never aim it at people or animals. Run it in a ventilated area, as the burner gives off exhaust. Refuel only when it is cool. Use the correct fuel oil. Check the mains lead before use. Wear heat resistant gloves and eye protection.
