      Function

      • The high pressure pump is driven by an intermediate transmission by a diesel engine.

      • Between the float container and the high-pressure pump, the water is heated via a heat exchanger located in the motor's cooling circuit.

      • When the jet operation is interrupted, the overflow valve switches to pressure-free water circulation and the motor continues running at idle speed.

      • The water is heated by a pressure-side burner with oil firing.

      • During hot water operation, softening agents are added to the water.

      • HDS 9/50, HDS 13/35 only (optional with HDS 13/20, HDS 17/20): The operating pressure can be selected via the speed control of the motor.

      • HDS 13/20, HDS 17/20 only: The high-pressure pump draws detergent. The proportion of detergent in the water can be adjusted using a dosing valve.
