Hot Aqua Blaster HUDSON 350 hot water high pressure washer

The Hot Aqua Blaster HUDSON 350 hot water high pressure washer is equipped with an industrial liquid cooled – Kubota diesel engine which is connected directly to the Aquabar ®
high pressure pump by a gearbox. The diesel engine is equipped with a heat exchanger, connected to the primary cooling system of the engine, the secondary water tank and the suction side of the high pressure pump.

The preheated water is subsequently – by a high-pressure high-efficiency heating coil – brought tthe desired final temperature. With this Waterkracht Ecoboiler system, you save up to 20% fuel consumption.

As a standard, the Hudson is equipped with a “Waterkracht-zero pressure control system” whichensures that; when closing the gun, the high pressure drops across the whole pressure group….from the high pressure gun up to the high pressure pump, also including the hose. When resuminthe cleaning job, the workload of the installation immediately restores the required pressure.
