While many equipment features of our HD 9/18-4 ST cold water high-pressure cleaner are freely configurable, a working pressure of 180 bar and a flow rate of at least 900 l/h also mean that it earns the title "all-rounder" for a variety of fields of application from industry to agriculture. Optional functions such as pressure relief, dry-running protection and water softening can also be integrated to protect the machine. For hygiene-sensitive areas, there is a variant with stainless steel casing, while very demanding cleaning tasks are best tackled with the hot water version and the option to suction cleaning agents. The recently developed innovations EASY!Force and EASY!Lock are always on board: While the EASY!Force high-pressure gun makes use of the recoil force of the high-pressure jet to reduce the holding force to zero, the EASY!Lock quick-release fasteners enable handlingthat is five times faster than with conventional screw connections, without losing any robustness or longevity. An extensive range of accessories and added details complete the sophisticated concept of the HD 9/18-4 ST.

Configurable components
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. 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 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.

The device running time can be precisely determined with the operating hour counter. Ideal for high usage frequency – for service interval optimisation.
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 dry running protection detects a shortage of water in the float tank and switches off the pump. The pump is thus prevented from running dry and becoming damaged. The dry running protection is recommended especially in cases where a constant water supply is not guaranteed or fluctuations are expected.
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.
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.
The frame and cover are made from powder-coated steel and are therefore particularly robust.
