Dualtech Tecnology System

Dualtech Technology System (DTS) is the innovative technology system for Annovi Reverberi patented high pressure washers that have 2 Power Units inside the machine.
 It can provide an increase in Washing Performance Power of up to 50%, both in terms of intensity and extension of the jet, with a resulting reduction in cleaning times. In fact, the flow rate from the 2 Power Units can reach up to 850 l/h, double that of a normal home & garden high pressure washer.
This also means that the jet can reach up to 5 metres away, allowing you to easily clean even very large overhead surfaces, which is difficult to do with a home & garden high pressure washer. Therefore, excellent performance but a high level of customisation. Based on the type of work to be performed, just one or both of the Power Units can be used with the Dualtech Technology System, thus varying the flow rate according to the surface to be treated.



e-4 Twin Flow D is the most lavishly equipped Twin Flow high pressure washer, complete with all standard model accessories plus Power Brush, the high pressure paving scrubber for cleaning large areas with incredible speed and precision. With its 3 nozzles and its bristles, it can triple the area cleaned to deliver better results in a much shorter time.
Like all Twin Flow machines, this high pressure washer increases cleaning performances by 50% with the Annovi Reverberi Dualtech Technology System (DTS) with its 2 power units. Thanks to this special system, this cold water high pressure washer is extremely versatile and powerful. If you have to deal with light dirt and small areas, such as motorbikes, cars, bikes and gates, you can activate 1 power unit for gentler washing. If you need to get rid of more stubborn dirt and process large surfaces such as outdoor walls, steps, swimming-pools and outdoor paved areas, you can operate 2 power units. This doubles the flow rate to 810 l/h, releasing all the power needed for in-depth cleaning.

The e-4 TWIN FLOW D high pressure washer is ideal for taking care of outdoor areas of the home, because it is particularly powerful and is complete with a floor cleaning brush. It is much higher-performing than a conventional domestic high pressure washer thanks also to its accessories, such as Twin Nozzle, an innovative fitting that enables the use of two wash nozzles at once, halving cleaning times.
e-4 TWIN FLOW D also features a hose reel and very manageable, easy to handle supersoft pressure hose, while with telescopic handle and wheels the machine is easy to move around.
