Annovi & Reverberi 6640N - Hot Water Pressure Washer - 150 Bar - 600 L/h

The 66 Series 6640N professional hot water pressure washer is an upgraded model in the AR Blue Clean line, equipped with a range of professional accessories. Thanks to its ability to remove stubborn dirt, such as oil and grease, it is particularly effective for a wide range of applications.

This model is designed to meet the needs of professionals who need to carry out frequent and intensive cleaning tasks, guaranteeing exceptional performance and a long service life.

The core of the 66 Series 6640N is a pump with a brass head and three ceramic axial pistons, equipped with a connecting rod-crank system and an automatic by-pass valve that resets the pressure in the pump head to zero.

The electric induction motor, complete with thermal protection, ensures reliable and safe operation.

The vertical boiler with double coil and refractory base, fed by a 22-litre diesel tank, allows an output water temperature of up to 110°C, as long as all operating conditions are met.

A safety pressure switch automatically switches the boiler off in case of water shortage, while the integrated thermostat allows the outlet water temperature to be regulated.

The TST (Total Stop System Timed) system activates the by-pass mode for a 20 seconds window when the gun lever is released, ensuring a timely restart within this period and reducing wear on the pump-motor unit, as well as limiting energy use.

After 20 seconds, the machine goes into Total Stop mode, an ideal feature for contexts of use with frequent interruptions and restarts.

The ergonomic handle and the pivoting front wheel facilitate transportation over different types of ground.

The professional accessories included, which can be connected via a threaded brass coupling, include: a 10 m steel-braided reinforced high-pressure hose, a high-pressure gun with safety catch and metal core, a 56 cm steel high/low-pressure lance head to be connected to the gun via a threaded screw coupling, and a high-pressure water outlet nozzle.

This combination of advanced features and high-quality accessories makes the 66 Series 6640N the ideal solution for professionals looking for a powerful, reliable and versatile pressure washer.

Why choose a hot water pressure washer? The use of a hot water pressure washer is required when oily or particularly stubborn dirt must be dissolved in the shortest possible 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. All things considered, the use of a hot water pressure washer allows: shorter washing time (for the same amount of dirt), improved disintegration of non-water soluble dirt, shorter drying time and less detergent; in short, lower fixed cleaning costs.

The HRC_EM pump is an essential component for those seeking reliability and high performance in professional cleaning operations.

This pump is equipped with three ceramic pistons combined with a connecting rod-crank system, a configuration that guarantees strength and durability even under prolonged stress.

The brass pump head adds further robustness, ensuring a long service life and superior corrosion resistance.

One of the most important features of the HRC_EM pump is the automatic safety valve that allows the pressure in the pump head to be reset. This mechanism not only protects the pump itself, but also increases the operational safety of the entire system.

The single-phase induction electric motor, equipped with thermal protection, is designed for efficient and reliable operation, minimising the risk of overheating. This additional protection extends the life of the engine and ensures its safe use in all conditions.

The system also features a remote total stop, which allows the pressure washer to be switched off without having to physically intervene on the machine, offering more convenient and safer control during use.

Finally, the HRC_EM pump is designed for suctioning water from a tank with a self-priming function, which allows it to be used even in situations where water is not supplied under pressure, making the entire system extremely versatile and suitable for a wide range of applications.

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

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

A crucial safety element is the safety pressure switch, designed to automatically switch the boiler off if water is not supplied, thus preventing overheating situations.

The pressure washer is also equipped with an easy to inspect water inlet filter and a diesel intake filter, both of which are crucial to maintain optimal 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 mention 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.
