The Annovi Reverberi 2591 hot water pressure washer, equipped with professional accessories, to remove the most stubborn and annoying stains like oil or grease. It is a semi-professional model suitable for demanding hobbyists and professionals.
Inside is an aluminium head pump with 3 oil-bath hardened stainless steel axial pistons , driven by an oscillating plate equipped with an automatic by-pass valve with pressure reset in the pump head.
The single-phase induction electric motor with thermal protection delivers a power of up to 2.2 kW, with a maximum flow rate of 420 l/h and a maximum pressure of 140 bar.
To raise the water temperature up to a maximum of 90°, the pressure washer is equipped with a vertical boiler with double coil and refractory material bottom, fed directly from the 4-litre diesel tank; there is also a safety pressure switch to switch the boiler off if there is no water.
Equipped with the Total Stop System, the high-pressure washer is able to remotely shut down completely when the gun lever is released and switch back on when the user resumes work, thus preventing overheating, extending the life of the high-pressure washer and reducing water and economic consumption.
The model also has an inspectable water inlet filter and a diesel suction filter. On the side of the pressure washer is the rotary switch for hot or cold operation, without the possibility of temperature control.
Its classic design ensures practicality and manoeuvrability, making it much easier to move the pressure washer around.
Why use a 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.
