Annovi & Reverberi 4590 - Hot water pressure washer - 160 bar - 500 l/h

The Annovi Reverberi 4590 hot water pressure washer is a semi-professional model, perfect for demanding hobbyists and professionals, equipped with professional accessories to remove stubborn dirt such as oil and grease.

Inside is a pump with an oil-bath crank-rod system with a brass head equipped with an automatic by-pass valve with pressure resetting in the pump head.

The single-phase induction electric motor with thermal protection delivers power up to 2.5 kW, with a maximum flow rate of 500 l/h and a maximum pressure of 160 bar.

To raise the water temperature to a maximum of 90°, the high-pressure cleaner is equipped with a vertical boiler with a double coil and refractory bottom, fed by a 4-litre diesel tank. A safety pressure switch switches the boiler off in the absence of water.

The Total Stop System allows the high-pressure cleaner to automatically stop when the gun lever is released and restart when work is resumed, preventing overheating, prolonging the life of the machine and reducing water and energy consumption.

The model also includes an inspectable water inlet filter and a diesel suction filter. On the side of the pressure washer is a rotary switch for hot or cold operation, with no possibility of adjusting the temperature.

The classic design of the pressure washer ensures practicality and manoeuvrability, making it easy to move the appliance around.

Why the hot water pressure washer? The use of a hot water pressure washer is necessary when oily or particularly tenacious dirt needs to be broken down in the shortest possible time. The washing efficiency of hot water is considerably higher than that of cold water (up to 50 per cent higher on certain types of residues), as the heat promotes the loosening of dirt, and the incidence of heat on the surface facilitates rapid drying. By using a hot water pressure washer we therefore have: shorter washing time (for the same amount of dirt), better disintegration of non-water soluble dirt, shorter drying time and less detergent; in short, lower fixed cleaning costs.

MOTOR: single-phase electric (230 V).

- Integrated diesel tank (4 l).

SCOPE:

• Max. flow rate 500 l/h (8.3 l/min). The flow rate is the most important data of a pressure washer, because it identifies, even before the pressure, the real power of the machine.

OPERATING PRESSURE:

• 160 bar max.

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

SCOPE:

• Max. flow rate 500 l/h (8.33 l/min). The flow rate is the most important data of a pressure washer, because it identifies, even before the pressure, the real power of the machine

OPERATING PRESSURE:

• 160 bar max, among the highest in its class.

Details:

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

To raise the water temperature to a maximum of 90°C, the pressure washer in question uses a vertical boiler with a double coil and refractory bottom.

This boiler is fed directly from the 4-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 if water is not present, thus preventing overheating situations.

The pressure washer is also equipped with an inspectable water inlet filter and a diesel suction 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 you to choose between hot or cold operation.

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

The controls are simple and straightforward, allowing the machine to be used quickly.
