High-pressure cleaner HDS 8/18 -4 St EU-I

Designed for continuous operation: The stationary HDS 8/18-4 St hot water pressure washer with oil burner is built for demanding cleaning tasks

The HDS 8/18-4 St is a stationary hot water high-pressure cleaner with an oil burner that provides an operating pressure of up to 180 bar. Its 4-pole, low-speed electric motor delivers the required power for continuous operation. The crankshaft pump with brass cylinder head delivers up to 800 liters of water per hour. The water break tank integrates a limescale protection system and a water filter to protect the pump. Detergent is drawn in and metered via a control valve, with a low-level indicator alerting the user when the detergent container is empty. Electronic monitoring of the oil burner and system parameters provides continuous operational control. A rotary switch or an optional remote control enables system operation, while service and maintenance points are structured for ease of access. A range of available accessories allows the HDS 8/18-4 St to be adapted to different cleaning tasks. The unit can be equipped with a pressure gauge, an operating hours counter, a second detergent dosing system, and a pressure relief system.
