The main advantage of the new 'standing' class of hot water high-pressure cleaners is the horizontal machine concept. This ensures a low weight and compact dimensions, so that they can be loaded and transported without problems. They can also be transported in vertical position in a station wagon. Thanks to their compact design, these devices take up a minimum of storage space when not in use. The large wheels and ergonomic push / pull handle ensure excellent maneuverability and mobility, even on difficult terrain. The axial high pressure pump is equipped with three plungers of hardened stainless steel and a brass cylinder head. A pressure switch automatically switches off the machine when the hand spray gun is closed. This relieves the pressure on the components and prolongs their lifespan. The high-pressure pump, the fan of the burner and the heating oil pump are driven by an electric motor and together form a drive module. This principle not only ensures a very compact assembly and high yield, but also makes the devices particularly reliable. The characteristics of Karcher's proven boiler technology are high performance in a limited place and full compliance with the legal emission standards. Single-phase device with two-pole, air-cooled electric motor. Axial pump with three plungers of hardened stainless steel. Detergent dosage at low pressure.
