A new version of the Berthoud professional-specification knapsack power sprayer uses a faster-charging battery that also trims a significant amount of weight off the operator’s back.
Powered pump drive in place of manual operation makes the Berthoud Vermorel 3000 Electric less tiring to use over long periods, while the electronic pressure control provides accurate and consistent spraying performance, with fast spray shut-off and self-calibration among its other features.
Weighing 6.2kg complete with battery, the ‘3000’ is more than 1.5kg lighter than its predecessor, which can only enhance the sprayer’s reputation as one of the most comfortable and secure battery-powered knapsack units available.
An ergonomic frame and harness similar to that used on top-end rucksacks is the key to comfortable use of all models in the Berthoud Vermorel range. Air can circulate between the sprayer and operator’s back, while support pads and wide padded shoulder and waist straps hold the sprayer securely in place.
“A sprayer that moves around on your back is the last thing you need when using a knapsack for long periods, especially over rough ground,” says Ian Sutton, professional products sales manager at Hozelock Exel. “The Vermorel’s harness ensures a snug but comfortable fit that helps the operator keep his balance and footing – which together with the powered pump makes a day’s work less tiring.”
The new Vermorel 3000 Electric has a light weight lithium-ion battery housed neatly beneath its 18-litre translucent tank. Unlike a conventional battery, it charges faster and provides consistent performance until fully discharged rather than gradually tailing off.
It will typically last five to six hours depending upon the spray pressure used but takes no more than two and a half hours to regain full power. Four LEDs on the control panel indicate the charge status in 25% increments and, being so light, it is no burden to carry a spare for long work sessions.
Alongside the charge status lights is an on-off rocker switch and another that selects one of three pressure settings – 3 bar and 1.5 bar for single nozzle spraying, and 1 bar for swath spraying with a Berthoud triple nozzle boom.
An electric control unit operates the double diaphragm pump and sets the pressure regulator; calibration after a nozzle change requires nothing more than a quick spray.
“The electronic control unit does the rest, adjusting the regulator to the selected pressure,” Ian Sutton explains. “Together with instant shut-off when the trigger is released, the Vermorel 3000 Electric is an easy as well as comfortable sprayer to use with precision.”
Other Berthoud features that are also part and parcel of the new sprayer’s professional specification are a generous tank opening and easy-to-grip lid, a place to store the lance, and Viton seals together with high-quality materials, fixtures and fittings for durability and a long service life.
The Berthoud Vermorel 3000 Electric comes with a 60-120cm telescopic lance and three nozzles. A trolley conversion is among the options available.
