Annovi & Reverberi 6670 - Hot Water Pressure Washer - 190 Bar - 780 L/h

The professional hot water pressure washer 6670 is an excellent model in the AR Blue Clean range, designed to perform at a high level. This device includes a range of professional accessories that increase its versatility and efficiency, making it suitable for a wide range of applications.

Thanks to its ability to generate hot water, this pressure washer is particularly effective in removing stubborn dirt, such as oil and grease, that often resist traditional cleaning methods.

The pump with brass head and 3 pistons ceramic with a connecting rod-crank system is a major component. Other features include:

• Automatic by-pass valve with pressure reset on the pump head.
• Three-phase electric induction motor with thermal protection.

The vertical stainless steel boiler with double coil and refractory bottom, fed directly from the 22-litre diesel tank, allows an output water temperature of up to 110°C. A safety pressure switch automatically switches the boiler off in case of a water shortage, while the thermostat on the machine body allows the user to select the outlet water temperature. Other boiler specifications include:

• Feeding from the 22-litre diesel tank.
• Integrated safety pressure switch.
• Thermostat for water temperature selection.

Equipped with TST – Total Stop System Timed – this machine activates in by-pass mode for a 20-second window when the gun lever is released, ensuring a timely restart within that period. After 20 seconds, the machine switches to Total Stop. TST system features include:

• Activation in by-pass mode for 20 seconds.
• Reduced wear of the pump-motor unit.
• Power consumption limitation.

The ergonomic handle and pivoting front wheel allow smooth movement over different types of ground.

Why choose a hot water pressure washer? It is mostly required the use of a hot water pressure washer whenever there is the necessity to remove oily or particularly stubborn dirt in the shortest time. The hot water washing performing levels turn out to be considerably higher than the ones reached by cold water (up to 50% higher in some cases), because the heat favours the dirt dissolution. Thus, the heat on a surface results in a quick-drying. Using a hot-water high-pressure cleaner therefore involves less washing time (for the same amount of dirt), better breakdown of non-water-soluble dirt, less drying time and less detergent; in short, lower fixed cleaning costs.

MOTOR: three-phase electric (400 V).

- Integrated diesel tank (22 L)

FLOW RATE:

• Max. flow rate: 780 L/h (13 L/min) The flow rate is the most important technical data of a pressure washer, because it indicates, even more than the pressure, the real power of the machine.

OPERATING PRESSURE:

• Max. 190 bar

Axial pump, brass head with three high-strength steel pistons.

FLOW RATE:

• Max. flow rate: 780 L/h (13 L/min) The flow rate is the most important technical data of a pressure washer, because it identifies, more than the pressure, the real power of the machine

OPERATING PRESSURE:

• Max 190 bar, among the highest levels of its category.

Specifications:

• Auxiliary motor for boiler ventilation.
• Vertical boiler with steel high-thermal efficiency coil.

To raise the water temperature to a maximum of 110°C, the pressure washer in question employs a vertical boiler with a double coil and refractory bottom.

This boiler is fed straight from the 22-litre diesel tank, which ensures efficient combustion for water heating.

A key safety element is the safety pressure switch, designed to automatically switch the boiler off in case of water shortage, thus preventing overheating.

The pressure washer is also equipped with an inspectable water inlet filter and a diesel intake filter, both of which are crucial to maintain optimum performance over time by reducing wear and tear on internal components.

On the side of the pressure washer is a rotary switch that allows the user to choose between hot or cold operation.

It is important to point out that there is no water temperature control once the desired option has been selected; this feature makes the pressure washer particularly suitable for applications where specific water temperature is not adjustable but needs to be constant, as in many industrial and professional applications.

Simple and immediate controls for a rapid use of the unit.
