With the new Accu Star 1.5, Birchmeier is launching a handy and comfortable battery-powered hand sprayer that offers consistent spray performance without manual pumping, making it ideal for precise application on potted and ornamental plants.

An integrated rechargeable battery generates a stable working pressure of 1.5 bar, enabling a consistent spray pattern. Users can operate the device for around two hours before the battery needs recharging, which takes approximately three hours using the USB-C charging cable supplied. The 1.5-liter tank is designed for small to medium-sized applications and offers sufficient volume for plant strengthening and protection measures.

This makes daily work much easier: the device operates at the touch of a button, requiring no effort whatsoever. Consistent pressure control ensures reproducible results—a particular advantage for sensitive crops that require finely metered wetting. An adjustable brass nozzle allows the spray pattern to be adapted to the crop.

The Accu Star 1.5 also scores points in terms of ergonomics: its compact design makes it easier to use for longer periods, while the 360° spray function allows you to work overhead or at an angle without interrupting the flow of liquid.

Birchmeier presents the two wheel battery pressure sprayer C 50 with CAS system (18 V LiHD / 8.0 Ah) and an electronic control system. This allows you to preset the pressure and maintain it at a constant level. It also monitors important functions such as the pump and rechargeable battery. A constant pressure results in constant spray characteristics. This maximises effectiveness while reducing the amount of solution used.

Depending on the pressure and the accessories used, the rechargeable battery lasts to 22 hours.

Birchmeier devices are famous for their well-thought-out, practical details. For example, the C 50 has a built-in mixing function. When the stirring mechanism is switched on, the spray liquid in the container is mixed with the help of the pump. Not only does this prevent liquid settling at the bottom of the container – it also allows spray solutions to be mixed in the device.

The benefits of the new sprayer are obvious: no smell of petrol or exhaust gases when working, and a lightweight, economical device which like all Birchmeier products is extremely easy to operate.

- The user sets the desired operating pressure anywhere from 1 to 6 bar using a rotary control.
- Thanks to a 50 litre scale on the plastic container, the fill level can be read easily.
- The 10 metre long hose which is wrapped around the neck of the device when it is not being used allows flexible use even at long distances.
- A practical holder on the side of the device is provided to store accessories like spray tubes.

Birchmeier is now offering his manual sprayers Iris 15, Flox 10, RPD 15, Profi Star 5 and Profi Star 3 with the new PR 3 pressure control valve as standard. Users not only benefit from the adjustable pressure and the resulting constant and even spray quantity, they also save spray liquid and thus protect the environment. In addition, the pumping effort is noticeably reduced by 30%.

The PR 3, which is simply pre-assembled between the trigger valve and the hose, ensures a constant operating pressure.

Before starting work, the user selects a pressure of between 1 and 3 bar, which is normal for plant protection applications, on the adjustment wheel of the valve. The pressure control valve regulates to this preset operating pressure, regardless of the pressure that is applied. If this is lower than the pre-set pressure, the flow will be interrupted. Higher pressure is regulated down to the pre-set pressure. If the pressure is constant, the flow will also remain the same.

In this way it can be applied with an even spray pattern. This saves money and protects the environment. A by-pass position can be set as well. The pressure control is switched off or the pressure in the tank will be reduced down to 0 bar to empty or to clean the sprayer.

The «Accu-Power» line won the Taspo Award 2017 in the category "Innovative Product".

In addition to the battery backpack sprayers REB 15 , REC 15 and REX 15 and the two-wheel battery sprayers A 50  and C50, the company now offers the b attery spray blower AS 1200  and pump station BM 1035 , the wheel barrow sprayers A 75 and A 130 which can be converted into rechargeable devices. This means that the manufacturer provides zero emission free products with reliable technology in various performance classes. 

As the first manufacturer the company introduced a comprehensive range of battery sprayers for plant protection. These powerful products are a real alternative to engine-powered sprayers.
Instead of noise and exhaust gases, users enjoy sophisticated technology, highly convenient operation and practical features.
The electronic regulating system acts as a control centre in all «Accu-Power» devices. First used in the REC 15 backpack sprayer, the intelligent control system has proven extremely successful in use.
Birchmeier attaches great importance to providing products tailored to the needs of all users in the plant sector. Because of this, various «Accu-Power» devices are available, offering different pressure ranges, application rates and operating times: 
Horticulture and landscaping/ cemeteries: Generally speaking, pest control in relatively small areas is required here. With a pressure of 4.5 bar and an operating time of more than four hours, the REB 15 will be adequate for most applications. For higher pressures and longer operating times, e.g. when applying fungicides, the REC 15 with up to 6 bar is recommended.

Sports grounds and golf courses: With an operating time of more than ten hours, the REX 15 is recommended for applying herbicides. The REC 15 is suitable for smaller areas.

Tree nurseries, fruit-growing and wine-growing: The REX 15 with 10 bar offers the manoeuvrability of a backpack sprayer with a high pressure for spraying range and stock penetration. The device’s high application rate also allows quick and efficient spraying.

Indoor plants: The A 50 cart sprayer or the «Accu-Power» pump station BM 1035 with an application rate of four to five litres per minute are ideal here.

Flowers and decorative plants: For propagation and young plants, high flow rates with low pressures are very important. With an operating time of more than eight hours, the REC 15 is ideal here. If a high level of stock penetration is needed for established or specimen plants, it offers ample performance thanks to a pressure of 6 bar.

Vegetable-growing/ speciality vegetable-growing: Large quantities of spraying solution and a long operating time are important here, e.g. in tunnels at the edge of a company site. With a 50 litre capacity and an operating time of up to 22 hours, the A 50 and C 50 meet these requirements. The rechargeable A 75 and A 130 cart sprayers are suitable for larger areas. The BM 1035 can be used as a pump station for even larger tanks.
