Product information and benefits

With a pressure of 210 bar and a flow rate of 1000 l/h, this stationary hot water HDS machine with a gas burner is ideal for continuous use in industrial and agricultural applications. It features a robust crankshaft pump with a brass cylinder head and durable powder-coated steel casing and frame. The pump is protected by a large water filter. The high-pressure cleaner includes an integrated water storage tank with limescale protection and empty indicator as well as a four-pole, low-speed electric motor with water cooling. The detergent is drawn in via a dosing valve and the empty level is displayed. The rotary switch makes operating the machine extremely easy. Installation and maintenance are also designed to be user-friendly, and the electronic monitoring system ensures a high level of operational safety. The machine is supplied without accessories; these can be selected individually for each workstation (point of use). Optionally available: pressure gauge, time counter for second detergent inlet, automatic pressure relief, various remote controls.

Easy and intuitive operation

Just one rotary switch for all functions guarantees simple operation without long training times. Practical error display informs users immediately and saves time. Self-explanatory symbols and a clear operating field make the machineeasy to understand, which increases productivity.

Gas burner tested, inspected and certified by Kiwa

Kiwa certification: objective requirements are fulfilled. High heat output. With proven and efficient Kärcher burner technology for low fuel consumption.

High-performance crankshaft pump

Reliable and durable Kärcher high-performance crankshaft pump ensures optimal pressure. Robust reciprocating pump with brass cylinder head and high-quality materials ensure a long service life. Longer working times, less maintenance effort and lower costs. Ideal for industrial use.

Water-cooled 4-pole electric motor (oil-heated)

Water-cooled motor for a high performance and long service life. For high performance and low maintenance costs. 4-pole, slow-running electric motor guarantees a long working time.

Electronic monitoring for greater operating safety

Flame and emission temperature monitoring, protection against water shortage/overpressure, limescale protection with empty indicator and malfunction monitoring ensure safe, long-lasting operation. Switches off in case of leaks or phase failure. Automatic shutoff in event of low voltage range or overvoltage.

High-quality equipment

The integrated water reservoir with limescale protection and empty indicator protects the heating coil and the entire system from lime deposits. Robust casing and frame made of powder-coated steel. The detergent intake system with dosing valve and empty indicator is just part of the high-quality equipment supplied as standard.

High flexibility

Truckwash A time counter and pressure gauge as well as automatic pressure relief to protect accessories and pipelines are available as options. In its extensive range of accessories for high-pressure cleaners, Kärcher has the right accessory for every cleaning task and every objective.

Large, transparent water fine filter

Easy-to-access water filter protects the pump against dirt particles in the water. Ensures long service life for all high-pressure components. Integrated water filter can be removed and cleaned without any tools.

Cleaning agent suction and dosing system for even better cleaning results

Using the dosage setting function, detergents can be dosed with precision to match the degree of soiling. The detergent intake system with dosing valve and empty indicator is just part of the high-quality equipment supplied as standard. A second detergent inlet with empty indicator and dosing valve is available as an option.

Simple maintenance and very easy servicing

Easy access to all service and maintenance components. Comprehensive service network with highly trained service technicians. Display of error codes, operating status, pump maintenance intervals and monitoring for faulty operation of the burner and the entire machine make servicing easier.
