The hot water pressure washers of the new middle- and super-class, including the KARCHER HDS 10/20-4 M, convince with their 5 main features: Environmental protection – Greater efficiency with the new ECO mode, service switch for controlling water hardness, turbo fan, precision detergent metering, optimized burner technology and a high-efficiency pump. Cleaning performance – Highly efficient cleaning is guaranteed by patented nozzle technology, ceramic pistons, turbo fan as well as increased pump efficiency. Accessories are optimized for specific applications and designed to exactly suit customer requirements. Mobility – The mobility concept features two casters, large rubber-tyred wheels, ergonomic handles, lifting points for handling with a forklift, lashing rings, and a recessed tread for tilting the machine to guarantee maximum manoeuvrability. Reliability – Guaranteed by flue gas monitoring, a corrosion-proof, flexurally stiff, robust chassis, machine protector system, three-piston axial pump with ceramic pistons, heat resistant flue outlet, and much more. Service friendliness – Easy access to all components that require servicing and a service switch to call up operating data at any time for troubleshooting. In the Eco setting the KARCHER HDS 10/20-4 M operates in the most economical temperature range (60°C) with full water flow. Burner cycles are optimised to reduce fuel consumption by up to 20% compared to full-load operation. The large, integrated fine-mesh water filter reliably protects the high-pressure pump against dirt particles. An integrated exhaust gas thermostat switches off the drive motor if the exhaust gas temperature exceeds 300°C. The soft damping system (SDS) compensates for vibrations and pressure surges in the high-pressure system.
