Pressure washer HD 9/18-4 ST
The space-saving stationary high-pressure cleaners from Kärcher with up to 6 supply points can be individually configured according to requirements and impress with low wear and tear.
The particular strength of the new generation of Kärcher cold water high-pressure cleaners is that they can be individually configured. This means that buyers only pay for precisely the equipment features which are really needed. Individual details can be easily retrofitted at a later date on request. The equipment features available include: A hot water version, which can be operated with a maximum input temperature of 85°C. A stainless steel casing for hygienically sensitive areas. Pressure relief to increase the service life. Dry running protection. Water softening for an especially hot water supply. An operating hour counter for efficient servicing. One or two cleaning agent suction option in high or low pressure use. Thanks to a wide range of accessories, the supply points can be specifically adapted to the cleaning task on site. Various remote controls, hose guide systems or a coinremote control are available. As individual as it gets!

Configurable components
Configurable components
The frame and cover are made from powder-coated steel and are therefore particularly robust.
The casing and frame are made from high-quality stainless steel. This makes them corrosion-resistant and less vulnerable to disinfectant cleaning agents. The components are therefore ideal for applications in the food sector – and wherever hygiene is of particular concern, strong disinfectant or cleaning agents are used or strict regulations apply. Even if the devices concerned are located directly at the place of use, corrosion due to strong aerosol formation can be prevented.
After the timer function has turned off the device, the high-pressure unit is still under pressure. The pressure relief reduces system pressure, thereby protecting the pressurised components. Especially recommended if lengthy pauses occur between the individual usage intervals.
Limescale formation in the system can be reliably prevented through continuous injection of water softener. In this way, damage due to calcification on the pump and other important components can be effectively prevented. Especially recommended for high feed temperatures and the ST-H version.
The device running time can be precisely determined with the operating hour counter. Ideal for high usage frequency – for service interval optimisation.
The preparation enables the control of the cleaning agent injection by remote control directly at the supply point. The low-pressure application is especially economical. No additional cleaning metering pumps are required. Minimal aerosol formation (spray) occurs during use. The "remote control preparation" is recommended especially for supply points which are repeatedly used by the same persons and for cleaning tasks which can be performed in the low-pressure range.

No additional cleaning metering pumps are required. Minimal aerosol formation (spray) occurs during use. The "remote control preparation" is recommended especially for supply points which are repeatedly used by the same persons and for cleaning tasks which can be performed in the low-pressure range. The variant with two cleaning agents is suitable, for example, for more complex cleaning tasks, distant supply points or for car cleaning.
The preparation enables the control of the cleaning agent injection by remote control directly at the supply point. The advantage compared with the low-pressure variant lies in the fact that no changing of the nozzle is necessary to apply the cleaning agent. The "remote control preparation" is recommended especially for supply points with frequently changing users, since no changeover at the nozzle which needs an explanation is required here, for operation by coin remote control and for cleaning tasks which require high pressure.
