The Kärcher HD 9/23 De is a heavy-duty diesel-powered cold water pressure washer designed for demanding professional cleaning in areas without access to mains electricity. Built for off-grid performance, high mobility, and reliable day-to-day operation, it is ideal for tough environments such as construction sites, farms, industrial yards, and municipal workspaces.

Powerful Cleaning Performance

With an operating pressure of up to 270 bar and a flow rate of up to 15 litres per minute, the HD 9/23 De delivers strong cleaning power for removing stubborn dirt, mud, grease, and heavy contamination from equipment, vehicles, and outdoor surfaces. Its maximum pressure reaches 270 bar, giving it the capability needed for intensive professional cleaning tasks.

Independent Off-Grid Operation

Powered by a reliable Yanmar L 100 V diesel engine, this machine generates the power it needs itself, making it ideal for use in remote locations and demanding outdoor environments. It can also draw water from alternative sources such as lakes or ponds, which makes it especially useful where infrastructure is limited.

Built for Tough Professional Use

The HD 9/23 De is equipped with a robust base frame built to withstand heavy-duty daily use in harsh working conditions. A large water filter and thermostat valve help protect the pump during operation, while the durable cart-style design supports dependable long-term performance.

Mobile and Easy to Use

Its ergonomic frame design helps make transport easier over uneven ground, while puncture-proof wheels provide lasting mobility on site. The machine also includes the EASY!Force Advanced trigger gun, Servo Control, on-board accessory storage, and EASY!Lock connections that speed up setup and dismantling compared with conventional screw fittings.
