Kärcher HDS 10/21-4 ST Gas EU-I | Stationary Gas Hot Water Pressure Washer

Industrial Gas-Heated Hot Water Pressure Washer for Continuous Heavy-Duty Cleaning

The Kärcher HDS 10/21-4 ST Gas EU-I is a high-performance stationary hot water pressure washer designed for intensive industrial and agricultural cleaning applications. Delivering an impressive 210 bar operating pressure and a water flow rate of 1,000 litres per hour, this powerful cleaning system is engineered to remove heavy grease, oil, mud, soot, and stubborn contaminants with maximum efficiency. Its gas-heated hot water technology provides exceptional cleaning power while reducing cleaning times and detergent consumption.

Built for fixed-location installations, the HDS 10/21-4 ST Gas is ideal for factories, farms, transport depots, food processing facilities, vehicle wash bays, and industrial workshops where a reliable, permanently available cleaning solution is required.

Powerful Gas-Heated Cleaning Performance

Unlike conventional electric hot water pressure washers, the HDS 10/21-4 ST Gas features a highly efficient gas burner system that generates hot water quickly and economically. Hot water penetrates grease and oily deposits more effectively than cold water, allowing operators to achieve superior cleaning results while using less water, energy, and cleaning chemicals.

The combination of high pressure and elevated water temperatures makes this machine particularly effective for cleaning heavy machinery, agricultural equipment, production areas, vehicle fleets, and industrial surfaces.

Engineered for Continuous Industrial Operation

Designed for demanding commercial environments, the machine incorporates a robust crankshaft pump with a durable brass cylinder head for maximum longevity and consistent performance. A low-speed, water-cooled four-pole electric motor reduces wear while ensuring reliable operation during extended cleaning sessions.

The powder-coated steel frame and housing provide outstanding resistance to corrosion and harsh working conditions, making the unit suitable for both indoor and protected outdoor installations.

Advanced Safety and Monitoring Technology

The Kärcher HDS 10/21-4 ST Gas EU-I is equipped with sophisticated electronic monitoring systems designed to maximise operational safety and minimise downtime. These include:

• Flame monitoring system
• Exhaust gas temperature monitoring
• Air pressure monitoring
• Water shortage protection
• Safety valve pressure protection
• Overcurrent protection
• Temperature limiter
• Automatic burner shutdown protection
• Integrated limescale protection system
• Electronic fault diagnostics and status indicators

These intelligent systems continuously monitor machine performance and help protect critical components, ensuring dependable operation in demanding industrial environments.

User-Friendly Design and Maintenance

A simple rotary control switch provides intuitive machine operation, while the integrated water storage tank, large water filter, and automatic limescale protection help reduce maintenance requirements and extend component life. The detergent dosing system enables precise cleaning chemical application for enhanced cleaning performance across a wide range of applications.

Optional remote-control solutions can also be integrated, allowing operators to start, stop, and control cleaning functions directly from designated wash stations.
