Colorado 530

Hot Aqua Blaster COLORADO 530

The Hot Aqua Blaster COLORADO 530 is equipped with an industrial – liquid cooled – Kubota turbo diesel engine which is connected to an industrial Pratissoli high pressure pump by gear belt transmission.

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 to the  desired final temperature. With this Waterkracht Ecoboiler system, you save up to 20% fuel consumption.

As a standard, the COLORADO is equipped with a “Waterkracht-zero pressure control system” which ensures 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 resuming the cleaning job, the workload of the installation immediately restores the required pressure.
