The new TLK 35 battery compressor replaces the classic hand pump and transforms pressure storage sprayers into fully-fledged systems for continuous use. Its high air output, intelligent energy management, and compatibility with the CAS battery system make the compressor an efficient solution for all professional spraying, foaming, and dusting applications. The TLK 35 eliminates the need for manual repumping, enabling continuous operation without physical effort. Thanks to its high air output, the battery compressor builds up pressure very quickly. It can even be used to operate foam and powder pressure storage devices without any loss of performance throughout the entire contents of the container. Unlike hand pumps, where pressure inevitably drops, the TLK 35 uses electronic technology to maintain a constant working pressure. Users can freely select the pressure within a range of 0.5 to 3.5 bar. The result is a consistent output and a defined spray pattern with a homogeneous droplet size. A clearly visible LED display provides information about the operating pressure used and the current charge status. Power is supplied via the manufacturer-independent CAS interchangeable battery system. Compatible with batteries from 2 Ah to 10 Ah, the TLK 35 offers flexible running times. Thanks to its intelligent control system, the pump only runs when needed (“pump-on-demand”), which maximizes the range per battery charge. With the development of the TLK 35, Birchmeier is launching a new generation of devices called the e-line. The series includes various models for different applications—from spraying and foaming to dusting—and thus offers a wide range of uses for a variety of professional requirements. The manufacturer's hand-operated three-, five-, and seven-liter plastic pressure storage devices can be retrofitted with the powerful compressor—in line with the principle of sustainability.

In fine vegetable cultivation, rock flour and powdered plant additives are among the proven means of specifically supporting soil activity, plant health, and nutrient dynamics. With the new e-DR 5, a battery-powered powder duster, Birchmeier is introducing the first device specifically designed for the efficient and even application of these substances. The device is powered by the TLK 35 battery compressor, which is the heart of the manufacturer's new e-line.

The main advantage of the system lies in its constantly available working pressure: the pressure generated by the TLK 35 is strong enough to apply even the finest material safely and continuously – without the physical strain that is typical of purely manual devices. The electronic control reliably maintains the set pressure at the desired level, thus producing a homogeneous dust plume. Users can flexibly adjust it between 0.5 and 3.5 bar to suit the culture, medium, and application target.

The powerful compressor builds up pressure in seconds. In practice, the 5-liter device can apply around three kilograms of powder in less than three minutes, depending on the agent. This makes the device attractive for larger areas as well. The high amount of dust per unit of time enables efficient work progress with consistent application quality. The replaceable 4.0 Ah 18-volt rechargeable battery from CAS allows the user maximum flexibility.

The e-DR 5 is part of the new e-line, whose devices are powered by the TLK 35 battery compressor. The series includes various models for different applications—from spraying to foaming to dusting—and thus offers a wide range of uses for a variety of requirements.

Birchmeier presents the e-Foam 7, a new 7-liter battery-powered foam device for the professional disinfection of plant trolleys and cultivation tables. Powered by the powerful TLK 35 battery compressor, the device generates a dry, adhesive foam, offering maximum efficiency when working. 

CC carts, crates, and other transport containers pass through numerous stages in the supply chain. Adhering plant residues or soil particles can introduce pathogens such as fungi, bacteria, or viruses, which then spread to the cultivation tables. This increases the risk of operationally relevant infections for nurseries. Foam disinfection offers effective hygienic protection. 

Birchmeier has developed the new e-Foam 7 battery foam device for mobile and flexible use in nurseries. The battery compressor builds up a working pressure of up to 3.5 bar and ensures uniform foam formation. The adhesive foam significantly extends the contact time of the disinfectant. With a 4.0 Ah CAS battery pack, around 300 to 600 m² of surface area can be foamed. The electronic control system keeps the pressure constant and enables even application – without any manual repumping. 

The e-Foam 7 is part of Birchmeier's new e-Line. All devices in this line use the TLK-35 compressor with CAS replaceable battery. This makes not only foam applications, but also spray and powder applications easy and convenient. At the same time, existing three-, five-, and seven-liter plastic devices from the manufacturer can be sustainably retrofitted with the compressor

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.

Birchmeier presents the e-Profi 7, a new 7-liter battery sprayer for professional users in horticulture. Equipped with the powerful TLK 35 battery compressor, the device offers comfort and maximum efficiency when working. 

At the heart of the e-Profi 7 is the TLK 35 battery compressor, which replaces the manual hand pump and builds up pressure in seconds. The desired working pressure can be continuously adjusted from 0.5 to 3.5 bar, and an electronic control system keeps it constant. 

The user can work for up to 200 minutes with a 2 Ah battery and a working pressure of 2 bar, applying up to 70 liters of liquid. The integrated, clearly visible LED display on the compressor provides information about the current pressure and the battery charge status at all times. The practical replacement batteries from the CAS family allow the use of different capacities from 2 to 10 Ah. 

The further development is also evident in the comfort and ergonomics: the newly designed device base with optimized support surface ensures stability. The multifunctional additional ring on the upper part of the container has a holding device for the compressor and, in addition to the traditional horizontal spray tube storage in the compressor handle, also allows vertical storage of the spray lance. 

The powerful battery compressor can be used not only for spraying applications, but also for foaming and powder application with the respective pressure storage devices. In line with sustainability principles, the manual pump can be replaced by the convenient compressor in the existing Birchmeier three-, five-, and seven-liter pressure storage devices.

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.
